What Is CoverShield U140 Gloss Concrete Sealer

CoverShield U140 is a heavy duty oil resistant concrete sealer.  It’s a water-based, polyurethane sealer that is highly stain resistant and provides a very effective resistance to: 

  • Oil
  • Acid
  • Chemical stains.

We recommend using it mainly for interior applications such as:

  • Trowel finished concrete
  • Smooth concrete.

Typical areas include auto garage floors, workshops, pole barns, or factories. The product has a lot of industrial applications, but it’s suitable for consumer-type situations as well. Customers report using it successfully on residential garage floors, driveways, etc.

It can repel virtually any petroleum-based chemical or oil solution that might get into a concrete surface. It’s ability to repel oil, diesel and hydraulic fluid spills is unparalleled.

It’s also used on decorative concrete. It’s a sealer for protecting colors on stained concrete. Simply apply it after staining your surface and it will provide a highly oil resistant concrete sealer to the surface.

CoverShield U140 oil resistant concrete sealer also has strong industrial uses due to it’s ability to resist and repel:

  • Diesel
  • Hydraulic motor oils
  • Cutting oils.

In factories where cutting fluids and lubricating oils are used, it’s a challenge to prevent those chemicals from penetrating the slab.  CoverShield U140 has no problem repelling these from entering a concrete surface.

One of the benefits customers rave about with U140 is that the surface prep is insanely easy.  As long as the floor is clean and it’s absorbent (water will soak into it), you can apply CoverShield U140.  It’s the exact opposite of applying an epoxy coating that requires surface grinding or expensive prep.

While epoxy coatings provide oil and chemical resistance, you have to significantly grind the concrete down so it sticks to the floor.   You also have to apply a very thick layer of the epoxy to get the maximum protection.

CoverShield U140 provides extreme protection… but with a very thin coat. On top of that, because it’s very thin, it doesn’t lift and peel like an epoxy would.

CoverTec’s U140 oil resistant concrete sealer clearly offers contractors and DIY-ers more bang for the buck because it:

  • Requires very little surface surface prep
  • Provides higher a coverage area
  • Is extremely easy to application. 

Warehouse Owner Erik T. Shares His Story About Using CoverShield U140

EPA Rules, Factory and Safety, OSHA, Customers Or Workers

Another area of application for CoverShield U140 is on floors where it’s critical to keep them clean and safe for workers, customers or the public.

Situations like:

  • OSHA & EPA regulations
  • Potential contamination areas
  • Clean rooms
  • Safety areas.

In these environments, keeping the contaminants from soaking into the workshop or factory floor concrete is no problem for the U140.  It will keep those substances on the surface, and allow you to see them and clean them easily.

Best Applications For U140 Concrete Sealer

The most suitable applications for CoverShield U140 are:

  • Concrete floors
  • Smooth concrete
  • Trowel finished concrete
  • Machine finished concrete
  • Polished concrete.

For example, floors you’ll find inside a workshop, a factory, a garage and auto-body shop. In cases where the floor area is large square footage, laying down solutions like epoxy coatings can be very expensive. Aside from the hefty costs of an epoxy product, they also tend to lift and peel easily.

CoverShield U140 outperforms epoxy solutions in every way.

The product is very effective as an oil resistant concrete sealer. It is much cheaper, does not lift and peel, and it lasts several years. Not to mention that it has higher coverage, typically 800 square feet per gallon.

The minimal surface prep is also another reason why customers love the U140. So long as the floor is clean and absorbent, you can apply the product to the surface.  With two coats you get a very oil and stain resistant sealer that easily holds up against:

  • Diesel
  • Cutting oil
  • Motor oil
  • Gasoline
  • Hydraulic fluids
  • Jet fuel
  • Etc.

The U140 provides great stain resistance in environments where these contaminants threaten the safety and cleanliness for workers and the publicWith regard to exterior use situations, CoverShield U140 performs very well in places like:

  • Parking decks
  • Loading docks
  • Driveways
  • Access ways
  • Ramps.

The U140 is also UV-resistant, making outside applications an easy decision. So long as the concrete is smooth or dense, and passes the water test, it’s a perfect fit for your situation. You can also use U140 oil resistant concrete sealer on decorative and stamped concrete surfaces.

Important Note:

If you’re dealing with a rough or broom finish concrete surface, a penetrating sealer like CoverTec’s PEN 55 may be more appropriate. It’s also very oil and stain-resistant but works better in those highly textured environments.

Applying CoverShield U140 - Recommended Steps

When applying the U140, follow these simple guidelinesThe concrete needs to be clean. It needs to be absorbent in order to apply the product.  If you’ve got new concrete, it may require some densification. You can use a densifier like CoverTec’s SurfaceFinish CD80.

It’s a good Colloidal Silica Concrete Hardener to use prior to sealing the surface. That’ll give you an even harder surface to bond with, and increase the results of the sealing processOnce the floor has been cleaned and densified, then you can apply the U140.  It’s best applied with a microfiber flat-mop. And you’ll typically get around 800 square feet of coverage per gallon. (You get very good coverage.)

At CoverTec, our customers use the term “thin to win.”

It’s all about thin coats. Two thin coats is the minimum requirement for any application.  You can also spray down the product, and then spread it thin. You can choose to pour it out on the surface, and then spread it around with a flat mopIf you’re doing large areas, I would recommend using a 3/8th Nap rollerpreferably 18 inches wide. This way, you get more efficient production.

Each coat takes about 3 hours to dry. It depends on the temperature of the slab, but if you’re in the mid 70 degree range, it’s typically about 3 hours.  The product’s ready to use, so you don’t have to dilute it. You just mix the 2 parts together and spread it out on the surface. Wait 3 hours for the first coat to dry properly, then apply the second coat.

If you need more time between coats, no problem. You can apply the second coat the next day… actually up to 48 hours after the first application.  The U140 has what we call “a long re-coat window.” As long as the surface is clean, you can come back and re-apply it. It bonds very well to itself.

Here is something to watch out for:

If the temperature is low… everything takes longer. Once you’re below 70 degrees (Fahrenheit), the dry time can double. In extreme cases, you could need 6 to 12 hours before the first coat dries.

Important Note:

Make sure the first coat is completely dry before you apply the second coat.

Oil Resistant Concrete Sealer - The Best Way to Protect Warehouse, Auto Shop and Industrial Concrete Floor Surfaces

Concrete is a great way to add structure to virtually any space, providing a durable and easy-to-style surface. But, not all concrete is created equal. And using an oil resistant concrete sealer is key to ensuring the protection of your heavy duty warehousing, automotive and industrial substrates so they can last for years to come.

Today, we’ll explore the benefits of using an oil resistant sealer to ensure your concrete stays looking great and is further protected from the wear and tear of everyday life. We’ll discuss what oils and chemicals it’s resistant to, how to select the right oil resistant sealer (a.k.a. oil repellent concrete sealer) , and tips for applying it for maximum effect. Let’s dive in and make sure your concrete is properly sealed for the long haul!

A Key Point About Oil-Resistant Concrete Sealers

For oil-resistant concrete sealers, it is best to look for a water-based acrylic sealant that is specifically designed for use on concrete surfaces. CoverShield U140 Gloss is the best product available today in this product category.

What is an Oil Resistant Concrete Sealer?

An oil resistant concrete sealer is a special type of concrete sealing agent designed to protect the surface from oil and other petroleum products. It provides adhesion properties, water repellency, and resistance to staining caused by oil and other petroleum-based materials. The need for oil-resistant concrete sealers has become increasingly important as more cities are turning to concrete rather than pavement asphalt as their preferred paving material, due to its cost benefits and durability. However concrete rather than asphalt is highly susceptible to oil staining and must be protected from stains by regular cleaning and re-sealing with an oil resistant sealer.

Oil resistant sealers come in both solvent-based and water-based varieties. Solvent-based sealers traditionally have been used as they offer protection against notable stains such as oil, gas, acid rain and grease; however, they can also produce dangerous fumes that may harm workers if not properly vented or monitored. Water based sealers provide protection against some but not all of these common stains unless they are specially formulated for this purpose. Also, they emit fewer dangerous fumes than their solvent-based counterparts. Ultimately, any home or business owner considering the use of an oil resistant sealer should weigh the pros and cons of each variety prior to selecting a product.

Oil resistant concrete sealers provide an effective way to protect one’s paved surfaces from the damaging effects of oil and other petroleum-based materials. Next, we will discuss the different types of sealers available on the market today for various applications.

  • According to a 2018 study, an acrylic-based sealer was found to be most effective in protecting concrete against water, oil and abrasion.
  • An epoxy-based sealer is highly resistant to chemicals and solvents, making it a suitable choice for oil resistance in concrete sealers.
  • Polyurethane based sealers offer the highest level of protection against oil, water, and abrasion, as well as providing a durable finish that resists degradation over time.  

Types of Sealers

When it comes to protecting your concrete surfaces, the right sealer is key. With so many options to choose from, it’s important to understand the differences between the types of sealers available – and then decide which one is best for your project.
There are two major categories of sealers: film-forming (or topical) and penetrating (or impregnating). Within these categories, there are a variety of specialty products such as acrylics and epoxies, as well as natural oil-based polymers like tung oil. Some sealers also contain solvents and volatile organic compounds (VOCs), while some are labeled as VOC-free.

Topical Sealers

These are film-forming sealers which create a visible top layer on the surface that will help protect against scratches, filth,oil staining and weathering over time. The downside of this type is that if they are not formulated correctly they can yellow or discolor with age and exposure to ultraviolet light, depending on its composition. Moreover, heavy use or extreme wear can degrade the performance of certain film forms if not applied correctly.

Penetrating Concrete Sealer

These penetrate below the surface of your concrete and form a protective bond which can help repel spilled liquids like oils. These types of sealers provide protection from within without changing the look or texture of your concrete; however, most penetrating concrete sealer products require multiple layers for complete protection and may need to be re-applied every two years or so after significant wear.

While both types have their pros and cons depending on the particular application, many professionals recommend using an oil resistant concrete sealer such as a natural water based topical sealer or oil-based polymer when protecting an interior floor surface against spills and other common abuses of foot traffic wear. Not only do these offer excellent waterproofing features with minimal yellowing over time, but they can often be applied in two thin coats or just a single coat with easy maintenance over time.

To reap the full benefits of an oil resistant concrete sealer, it’s important to fully understand its use, application processes, and potential pitfalls before beginning any project. In the next section, we will explore some of the major advantages offered by these types of sealers to understand why they might be suitable for your needs. Next up: Benefits of an Oil Resistant Concrete Sealer!

Critical Takeaways For Achieving Oil Repellent Concrete

It is important to choose the proper sealer for any concrete project. There are two major categories – film forming and penetrating. Film forming creates a visible layer that helps protect from scratches, dirt, and weathering, but can yellow or discolor with age or wear if not formulated correctly. Penetrating seals provide protection from within without changing appearance, but may require multiple applications over time. An oil resistant concrete sealer, such as natural oil-based polymer, is recommended for interior floors as it waterproofs the surface, with minimal yellowing, and can often be applied in two thin coats with easy maintenance. It is important to understand application processes and potential pitfalls before beginning a project.

Benefits of Using Oil Resistant Concrete Sealers

Protecting concrete surfaces from oils and other harmful liquids is an important task for any homeowner or business owner, as untreated spills and leaks can cause unsightly damage to floors and other surfaces. One way to protect concrete surfaces from these liquids is by using an oil resistant concrete sealer. This type of sealer offers many benefits over traditional sealing methods, including protection from dangerous fumes and improved longevity.

One of the most significant benefits of using an oil resistant concrete sealer is that it helps to keep the surface clean and free of potentially damaging oils, grease, and other hazardous liquids. Because these sealers form a permeable barrier on the surface, they can quickly absorb and contain hazardous liquids before they have a chance to seep into the underlying material. As a result, a treated surface will be protected from potential staining and discoloration caused by oil and other chemical spills.

In addition to providing protection from oil-based liquids, an oil resistant sealer will also provide a greater degree of protection against gas vapors emitted from machinery or chemical processes. These vapors can cause permanent damage to concrete surfaces if not properly sealed, so the presence of an effective sealer provides an extra layer of defense against these dangerous fumes. Furthermore, an oil resistant concrete sealer provides much better longevity than non-resistant sealers, requiring fewer reapplications over time for ongoing protection.

The use of oil resistant sealers isn’t without its drawbacks; some of them can be more costly than standard sealants and require careful application during installation in order to ensure maximum protection. More importantly, many oil resistant sealers are composed of potentially hazardous chemicals or volatile organic compounds (VOCs) which must be handled with caution according to label directions; misuse could lead to personal injury or property damage.

Despite drawbacks related to cost and potential hazards associated with VOCs in certain concrete sealers, using an oil resistant sealer offers the best way to shield surfaces from potentially damaging oils and fumes. In the following section we will discuss additional methods used to achieve maximum protection from hazardous fumes when using an oil resistant concrete sealer.

Protection from Dangerous Fumes

Using an oil resistant concrete sealer is an important consideration when it comes to protecting your concrete surfaces from potentially dangerous fumes. Oil-based products, such as motor oil, paint and solvents, can release hazardous fumes into the air if not properly sealed. These fumes can contain carcinogens and other toxic chemicals. By using a sealer that is specifically designed to be oil-resistant, you can help keep these dangerous fumes out of your home or business environment.

For concrete surfaces that are regularly exposed to motor oil and other petroleum-based liquids and fumes, the best method for protection is to use a sealer that contains artificial chemical agents designed to resist absorption. Many sealers also offer protection from naturally occurring vapors such as radon gas and formaldehyde from building materials.

Another type of oil-resistant sealers are those that are composed primarily of natural ingredients such as vegetable oils, resins and waxes. Although these types of sealers may have limited resistance against saturated oils, they do provide environmental advantages due to their natural sources. Opponents often argue that these sealers lack the endurance necessary to survive harsh conditions – although this largely depends on the strength of the individual product.

Overall, oil-resistant concrete sealers should be used judiciously depending on the particular application. Selecting a product with the appropriate level of protection is essential in order to ensure safety from dangerous fumes. With this in mind, let’s move onto the next section which looks at how to choose the right oil resistant concrete sealer.

How to Choose the Right Oil Resistant Concrete Sealer

When it comes to maintaining the safety and appearance of auto shop, gas station and industrial surfaces, selecting the appropriate concrete sealer oil stained environments like these need is essential. There are various products on the market that claim to offer superior protection, so it can be difficult to determine which one is best for your project. To make sure you get the best protection available, there are a few key factors to consider.

First, look at the type of surface you aim to protect. Different types of surfaces will require different formulas and levels of protection. For example, oil-based sealant may not provide adequate protection for exterior surfaces exposed to salt and moisture, such as parking lots. In these cases, epoxy-based sealant might be the better option.

Next, consider the size and complexity of the project. If it’s a small area with just a few cracks or joints, you might want to go with a water-based sealer instead of an oil-based one. Water-based sealers typically provide thinner layers with less chemical buildup and are often easier to apply than oil-based ones. However, if you have highly porous surfaces or areas that require more intense treatment, an oil-based sealer may be a better option due to its thicker and longer lasting layers of protection.

Finally, inspect the product labels before making your purchase. Make sure that the chosen product is certified by reputable third parties and complies with industry standards for durability and environmental safety.

Selecting the right oil resistant concrete sealer requires research and consideration in order to ensure maximum long term protection for your concrete surface. With this knowledge in mind, you can rest assured that you have made an informed decision based on your exact needs and requirements.
The next section explores the lasting durability of your sealed surface – a key factor when determining how much protection your project needs now and in the future. 

The Lasting Durability of Your Sealed Surface

The lasting durability of a sealed surface is an important factor to consider when choosing the best sealer for your concrete. Sealed surfaces have the advantage of being more resistant to moisture and dirt, which can protect the integrity of your concrete for a longer period of time. Many of the newer sealers are formulated to provide superior protection against oil stains, as well as making sure that the sealer does not wear off too quickly. Oil resistant concrete sealers are ideal for protecting against oil spills or other oily substances, as they will allow them to “bead up” on the surface, making them easier to clean off.

There is debate, however, over whether the additional protection from oil is worth investing in. Some argue that all sealers will eventually wear off over time and regular maintenance and cleaning will provide better protection in the long run than investing in an oil resistant concrete sealer. This may lead some people choosing to go without an extra layer of protection entirely, or use a non-oil resistant sealer which may be more cost effective in the short term.

No matter which option you choose, it’s important to weigh the pros and cons carefully and decide what fits best within your budget and needs. In either case, it’s crucial to properly maintain your sealed surface to ensure maximum longevity. Next, we’ll discuss how best to apply an oil resistant concrete sealer for maximum protection and longevity.

Applying an Oil Resistant Concrete Sealer

Applying an oil-resistant concrete sealer is the best way to protect your concrete from damage caused by oil spills, stains, and harsh weather conditions. This type of sealer creates a barrier between the concrete surface and any contaminants so any liquids that come into contact with the concrete are not able to penetrate it. When purchasing this type of product, it is important to select one specifically designed for concrete, interior floors or exterior decks. Additionally, you should consider the amount of protection it will provide, ease of application, drying time, and durability before making a purchase.

For DIYers, the best option is usually a polymer-based sealer. These are typically paint-on products that form an invisible film on the surface of the concrete wall or floor. Once applied, they create a watertight layer that prevents moisture and oils from penetrating into the concrete and causing damage. Polymer-based sealers tend to be resistant to UV light, chemicals, and abrasion which makes them perfect for exterior applications where there is more exposure to these potential hazards.

Another option for DIYers is a solvent-based sealer. These create a thicker coating than water dispursed polymer-based products but still form a barrier that resists water and oil penetration. They are also heat resistant which makes them great for areas where high temperatures may be present. However, it is important to note that solvent-based coatings are not as durable as their water based polymer counterparts and will eventually break down after extended exposure to hot or cold conditions.

Due to their increased cost and labor intensity, professional installation services often opt for modified acrylic resin sealers. This type of product creates an even stronger bond with all types of concrete because it penetrates deeper than other types of sealers. When applied properly, this bond can last up to 10 years without needing reapplication or repairs – making it perfect for commercial settings where frequent foot traffic can cause extensive wear and tear on surfaces over time.

No matter what type of product you choose when applying an oil-resistant sealer, it is important to read the instructions carefully in order to ensure proper application and maximum performance. Proper preparation is key for all types of sealants so make sure any loose debris has been removed from the surface before beginning any work. Additionally, always apply multiple thin coats rather than one thick layer in order to get the most out of your product’s lifespan and guarantee maximum protection against potential oil damage in the future.

Applying an oil-resistant concrete sealer is essential for protecting surfaces from liquid spills and other damaging elements that can have long-term effects on their structures but finding the right product type depends on many factors such as location, exposure levels, desired results, etc. Now that we have examined some popular options available today let’s move onto creating a strong adhesive bond in the next section.

Creating a Strong Adhesion

Creating a strong adhesion between the concrete and oil resistant sealer is essential to ensure maximum protection. These types of sealers typically require careful surface preparation, good cleaning, and thorough drying before application. The surface must be free of dust, dirt, grease and other contaminants in order to achieve optimal adhesion. Many contractors suggest using an acid etching compound prior to application to help create a rough profile on the concrete that will anchor the sealer. This can be labor intensive depending on the size of the area needing treatment but it is well worth the effort for an optimal end result.

For some projects where labor costs are high, mechanical abrasion may be used instead of chemical etching. Products like abrasive blasting or diamond grinding can expose fresh pores and peaks that will aid in proper adhesion. As with any type of surface treatment, care must be taken to ensure complete coverage for a successful installation. Next generation sealers like CoverShield U140 are formulated with special adhesion promoters that eliminate the need to etch or grind the concrete surface.

Once appropriate preparation has been done, the next step is to apply the sealer. It is generally recommended to apply two coats; it’s often helpful to use alternate application techniques (i.e., spraying one coat and roller brushing another) to enhance adhesion between the sealer and concrete. This will help form a nearly impenetrable shield so that oil won’t be able to seep into your concrete surfaces over time.

Proper surface preparation and meticulous attention during application are key factors in making sure you have a strong adhesion between the sealer and your concrete surfaces. When these steps are done with care, your oil resistant concrete sealer should give you many years of protection against oil-related wear and tear.

Now, let’s look at what types of products are available so we can determine which type of oil resistant concrete sealer will best suit our needs; this will be explored further in the following section about “review of the best oil resistant concrete sealers”.

What to Look For in an Oil Repellent Concrete Sealer

When looking for a way to protect your concrete from any type of oil, the best option is to use an oil resistant concrete sealer. There are many different types and brands of concrete sealers available, so it can be difficult to determine which one will work best for your specific needs. Fortunately, there are some key factors that should be considered when selecting the right oil resistant concrete sealer for your project.

The first factor to consider is the composition of the sealer. Some oil resistant sealers are water-based, while others are solvent-based or contain a combination of the two. For example, solvent-based alternatives tend to offer better protection against oils than water-based options, but they can cause environmental damage if not properly handled. Similarly, water-based sealers are more environmentally friendly and easier to apply but unless they are formulated correctly lack the same protective quality as solvent-based alternatives.

Another factor to consider when selecting an oil resistant concrete sealer is its ability to resist various types of oil. Solvent-based options tend to provide better protection against hydrocarbons than other alternatives, while some water-based models have been formulated specifically for petroleum-related spills and stains. Depending on the area being sealed and the type of exposure it will face, it’s important to select a product that will be able to withstand exposure to oils you may encounter in a given environment.

In addition to composition and resistance factors, it’s important to also consider the application method and coverage area provided by the product you choose. Different products come equipped with different instructions, so make sure you read them thoroughly before getting started with any application project. Furthermore, most oil resistant concrete sealers come in containers that denote their range of coverage; this is an important number to understand since it will inform how much product you will need for your particular project.

When searching for an oil resistant sealer that meets all your needs, it’s essential that you evaluate all the criteria outlined above prior to making a selection. While there isn’t one “ideal” option out there for everyone, doing research and considering all available options beforehand can help ensure you purchase the best product for your specific situation.

With all this information in mind, let us move onto our conclusion section which explores why selecting an oil resistant sealer is so important.  

Conclusion

When it comes to protecting your concrete surface, oil resistant concrete sealer is the best way forward. It is a cost-effective solution that is reliable, easy to apply and can provide protection against oil for as long as two years before reapplication is needed. With proper application and maintenance, concrete surfaces that are sealed with an oil resistant sealer will last for many years without the need for frequent repairs that non-sealed surfaces sometimes require.

On the other hand, when using an oil resistant sealer, it is important to remember that it is not completely impermeable and may eventually let some oils leak through. This should be taken into account when first applying the sealer, by ensuring everything has been properly prepared beforehand. Ultimately however, due to its affordability, reliability and proven track record in dealing with oils; oil resistant concrete sealer remains the top choice of professionals worldwide.

Frequently Asked Questions

How does U140 work?

CoverShield U140 is a tough, industrial grade, water based clear gloss or matte finish polyurethane sealer. We use  a low viscosity highly crosslinked advanced blend of polyols resins in a water-based formulation.  When these resins react together the thin film formed, that is highly resistant to oil and automotive fluids, acids, alkaline solutions, solvents, food stains and cleaning agents. U140 is designed to penetrate the subsurface of the concrete and form a thin film on the top surface which provides an absolute barrier to oil.  This thin film is non yellowing, does not lift and peel (like thicker coatings) and is easy to keep clean repair and recoat.

How does CoverShield U140 compare to a penetrating sealer?

Our product is an aliphatic polyurethane.  It forms a  thin film across the surface of the concrete that is and absolute barrier to oil and  harmful chemical staining.

Penetrating  sealers do not form a film at the surface. The work by blocking the pores in the concrete and restricting the oil and other contaminates getting into the sub surface of the concrete.  The very top surface is still exposed however so staining is still possible and there are limitations to the amount of oil exposure the penetrating can withstand.

How does CoverShield U140 compare to an epoxy coating?

CoverShield U140 creates a thin, highly durable layer on the surface of the concrete that is very oil resistant.  The product that resists peeling and scratching, holds up heavy foot and forklift traffic. Furthermore, U140 matte or gloss finish is UV resistant and can be used interior and exterior.

U140 does not require extensive surface preparation in order to bond to a smooth surface.  This makes the product very effective on smooth   steel troweled, densified or polished concrete. The high coverage per gallon.( 800 sq. ft /gal or greater)  compared to 150 -200 sq. ft per gal for an epoxy coating .  This makes the U140 a high-performance high value solution.  A lot of bang for the buck!

Epoxy coatings have excellent oil and chemical resistance but are not UV resistant and are for interior use only.  Application thickness is higher and surface preparation needs are greater for an epoxy . This drives up the overall cost of and epoxy coating compared to the CoverShield U140.

Is CoverShield U140 Shiny?

U140 comes in two sheens, Semi-Gloss, and Matte. The matte is a flat no shine finish.  The semi-gloss has a medium gloss appearance. The gloss level can be increased by applying a prime coat first and/or densifying the concrete using our SurfaceFinish CD80 product.  U140 can also be burnished with a high-speed burnishing pad to increase the gloss. To increase gloss by burnishing, wait at least 24 hours after the final coat is applied. Then use a high-speed burnisher (1500–2500 RPM) fitted with 800, 1500 and 3000 diamond grit burnishing pads, or Hog Hair pads. Start with 800 grit and burnish at a fast walking pace.

Can I color the floor first?

For best results we recommend staining the concrete first using our color stain UV products.  The ColorStain UV can also be added directly to U140 to impart color in a single step.

Should I use a concrete Densifier?

The use of a concrete densifier depends on the quality and strength of the concrete. Densifying the concrete can harden the concrete and increase overall sealer adhesion and durability.  Densifying can also help with increase shine.   We recommend the use of  our Surface Finish CD80. This product is a colloidal silica with very small  particle size (3 to 8 nanometers).  These nanoparticles mean that the densifier penetrates deeper and reacts faster (30 to 60 minutes) than standard concrete hardeners.   SurfaceFinish CD80 is supplied in a concentrate (1 gal makes 4 gals ready to use) so it is very economical.

Is the Product chemical resistant?

Yes, U140 is very chemical resistant to a variety of substances you would see in a garage setting, for example brake fluid, oil, acid, bleach, salts, etc. We use  a low viscosity highly crosslinked advanced blend of polyols resins in a water-based formulation.  When these resins react together the thin film formed  is highly resistant to oil and automotive fluids, acids, alkaline solutions, solvents, food stains and cleaning agents.

A major benefit of the CoverShield U140 is that it is a thin film system.  It penetrates the  sub surface and leaves a thin film on top of the concrete. This film is very oil resistant and makes concrete easy to clean and maintain.  Also, it does not  flake and peel like epoxy.

How long does it last?

This depends on the amount of use, type of use, chemical exposure, and of course how well the finished surface is cleaned and maintained. Typically, you should expect to 3 to 5 years before having to do a recoat.  Based on foot and vehicular traffic, floor should be swept clean with broom or a microfiber dusting pad.

In a workshop environment or where there is heavy vehicular traffic, floor surface should be mopped daily or cleaned with a floor machine using a neutral cleaning solution.

Will it scratch?

Yes, All coatings will scratch, no coating is total scratch proof!

Having said that U140 is a very durable sealer and has a high scratch resistant.  If the surface does get scratched it is easy to repair.   Sand the damaged area with 400 grit sandpaper. The aim is to feather out the scratch and prepare the repair area for to coating. Then wipe up the dust using neutral cleaner or rubbing alcohol.  The repair area needs to clean dull and dry. When dry apply 2 or 3 thin coats of U140 .  Allow 24 -48 hours before opening to vehicular traffic depending on temperature and humidity.

Is it easy to apply?

Yes, U140 is simple to apply. On a smooth trowel finished concrete you simply spray the first coat using a pump-up sprayer, and then use a flat microfiber mop and spread a nice even thin coat. Allow the first coat to dry before applying the 2nd coat.  The 2nd coat should be applied in the same manner as the 1st.

If the surface is polished (maximum 800 grit ) or very dense we recommend you apply a prime coat first.  Apply the prime coat by pump up spray only.  No mopping.

If the surface is  very textured uneven or broom finished, then a U140 should be applied by 3/8th nap microfiber roller. Please refer to the technical datasheet for more in depth application instructions.

How long does it take to dry?

Light foot traffic is possible after 6-8 hours and heavy foot traffic is possible after 12 hours at 77deg F (25 deg C) and 50% humidity. Dry time is very dependent product thickness, temperature and humidity.  The higher the temperature and humidity the faster it will dry. If the slab is cold and the air is dry the dry time will be significantly extended.  It is very important to allow each coat ( including primer cost if used) to dry fully  before applying the next coat (topcoat). That way the whole system will dry faster. When the last coat is tack free Allow a further 24- 48 hours before vehicular traffic depending on application thickness, the temperature and the relative humidity in the room.

What condition should the concrete be in before I coat?

The concrete surface being coated must be a minimum 7 days cured, structurally sound (200psi or greater according to ASTM D4541), clean and dry. It must have low moisture-vapor transmission (6 lbs./1,000 ft ²/24 h (or 15 g/m²/24 h) or lower).

It is very important to make sure that the concrete is absorbent. Any existing sealer or curing agent etc. that might interfere with the absorption of the u140 sealer should be removed.  A quick test for existing sealers is to conduct a water test to see if the concrete will darken when wet.  Simply pour 1 fl.oz of water on the concrete and see if it will darken the surface after standing for 5 minutes.  If after 5 minutes the surface does not darken prepare the surface by sanding the floor with a 60-200 grit sanding screen or diamond abrasive pad. Remove all residue before sealing.

Is the pot life important?

Yes, the pot life is very important.  The pot life is basically the amount of working time you have  to apply the product once the product is mixed.  CoverShield U140  has a 2 hours pot life at 77deg F (25 deg C). Any remaining  after that point must be thrown away. Using product once in its past its pot life will result in product failure.

Can I recoat CoverShield U140?

If the surface is clean you can recoat with CoverShield U140 within the first 48 hours of previous application. After 48 hours, sand or scrub entire surface using After 48 hours, mechanically abrade the entire surface using an auto scrubber fitted with a 220-sand screen or a Marron Surface Preparation Pad (SPP pad). Clean with GlossClean neutral cleaner and allow substrate to dry. Apply CoverShield U140 within one hour.

Can I use the CoverShield U140 Floor Coating outside?

Yes, CoverShield U140 is a UV resistant non yellowing polyurethane coating and can be used exterior and interior applications.

Does the floor get slippery?

CoverShield U140 has good anti slip properties when dry but it can get slippery when wet on a smooth surface.  Increase slip resistance can be achieved by mixing in our CoverGrip anti slip additive at the time of application.

How many square feet will a full kit cover?

Approximately 800ft2/gallon (19.6 m2/liter) per coat depending on the density and porosity of the substrate. Coverage can be higher on the 2nd coat. The important thing is not  to over-apply. This product should be applied thinly and evenly.

Can U140 be used for other surfaces other than concrete?

CoverShield U140 is recommend for use on concrete and terrazzo surfaces only.  These include steel trowel, polished concrete( up to 800 grit) .  U140 is not recommended for non-porous surface like epoxy, polyurethane or ceramic and porcelain.

Can You Apply U140 Over Epoxy?

No, if you are going to use epoxy, then you would use our product called StrongSeal Plus.

Can You Apply U140 Over Acrylic Paint?

No, if you have an acrylic product on your floor, you must strip this product first, then apply the U140.  Alternatively, you can use StrongSeal Plus.

Can You Paint Epoxy Over U140?

Yes, if the U140 is sanded to create a profile, you could then coat with an epoxy product.

What are the cleaning and maintenance procedures?

Based on foot and vehicular traffic, the floor should be swept clean with broom or a microfiber dusting pad.

In a workshop environment or where there is heavy vehicular traffic, the floor surface should be mopped daily or cleaned with a floor machine using a neutral cleaning solution.
