Protect Your Surfaces Against Fuel Stains With CoverShield U140 Matte Gas And Oil Resistant Concrete Sealer
These days, concrete is everywhere. Outside its used in walkways, driveways, and patios. Indoors, flooring includes workshops, garage floors,and commercial flooring. As such, it’s important to protect your concrete from everyday wear and tear that could result in unsightly stains, spills or cracks. Fortunately, you can do just that with a gas and oil resistant sealer. By applying this sealer, you can ensure that your concrete surfaces remain sealed and shielded from potential damage. In this blog post, we’ll explore exactly how a gas and oil resistant sealer works and how it can help protect your concrete surface. So read on to find out more about one of the best ways to protect your concrete!
A Quick Breakdown of Key Points
CoverShield U140 Matte is widely considered to be the best gas and oil resistant concrete sealer available. It offers superior protection from oil contamination but also from water, moisture, chemicals, UV rays, and salt with minimal effort needed for maintenance.
What Is A Gas And Oil Resistant Concrete Sealer?
A gas and oil resistant concrete sealer is an important part of protecting your concrete flooring. This sealer is designed to provide a barrier across the concrete, which contains a network of polymers that help repel gas and oil-based fluids, dirt, and oils. It should be applied in two thin coats. First, the base layer provides a long-lasting protective coating that helps repel fluids before they can penetrate the concrete. Then, the topcoat not only provides additional protection against solvents, fuels, and chemicals but also adds different shine and gloss levels to the surface of the concrete. This shine levels range form matte flat finish to a high gloss finish
This type of sealer provides several advantages when used on exposed or non-polished surfaces like driveways, sidewalks, and patios where exposure to gas and oil spills are more likely to occur. The most obvious benefit is increased protection from oil and petroleum based fluids but also form dust, dirt, stains, and damage caused by exposure to these types of materials. Not only will this help protect industrial or the decorative concrete finish below it; but it will also help extend its lifespan as well as make it easier to clean up any spills should they occur.
On the other hand, there are some drawbacks associated with using this type of sealer. For example, since this sealing product does not let air in or out of the concrete surface there can be problems breathing properly due to humidity trapped underneath the sealed surface during humid weather conditions. Additionally, some types of topical sealer can be difficult to reapply once it has begun deteriorating due to the number of layers already present on the surface. Sealers applied in thin coats with adhesion promoters can help mitigate these issues
Gas and oil resistant concrete sealers offer reliable protection for machine troweled interior surfaces and exposed exterior surfaces and can be beneficial in preventing further damage from occurring due to spills or exposure to harsh elements. The next section discusses some of the key benefits that come from protecting your concrete with this type of sealer.
The next section will explore an important aspect of concrete care – protecting your investment with gas and oil resistant sealers – outlining its key benefits for your property’s longevity.
- A study published in 2020 found that polyurethane-based concrete sealers are among the most effective options for protecting against gas and oil penetration.
- Concrete sealed with a polyurethane-based sealer can typically resist fuel spills of up to 33 PSI (pounds per square inch) without compromising adhesion.
- According to research from 2020, acrylic- or epoxy-based concrete sealers can protect against water, salt, and mild acids but may not provide adequate protection against gasoline or other petroleum products.
The Benefits Of Concrete Protection
Protection is key when it comes to concrete surfaces. A sealant helps preserve the longevity of concrete with added strength, lower maintenance, and improved aesthetics that make all the difference in appearance, saving you both money and time in the long run. Gas and Oil Resistant Sealers provide superior protection to concrete from any potential spills or leakages from fuel-based substances, safeguarding the surface from any damage caused by their chemicals.
The benefits of concrete protection are numerous, one of them being that protective coatings help reduce staining, cracking and spalling that can occur on concrete due to extreme weather conditions or improper curing processes. This will ensure you achieve a superior outdoor living area that stays beautiful for as long as possible. Moreover, using a protective coating on your outdoor surface will increase its strength, making it resistant to abrasion and protected from potential freeze-thaw cycles which can weaken the structure of untreated surfaces over time.
Gas and oil resistant sealers also extend the life span of the concrete outdoors by providing a barrier between the surface and contaminants such as dust, moss, mold or dirt that could seep into the structure of your paved area. Besides improving the overall look of your concrete paving structures, protective coatings using a anti slip additive also improve traction on wet surfaces reducing slip hazards – an important consideration for areas with high foot traffic.
However, there are those who argue that protecting concrete surfaces with sealants is an unnecessary expense as some treatments can create a slippery surface or shine to otherwise dull concrete slabs. In spite of this debate, it is important to note that applying protective sealants provides more advantages than drawbacks in terms of preventing costly repairs down the line and ensuring you have a safe and hygienic environment for years to come.
Therefore, whatever your preference is in terms of protecting interior concrete or decorating exposed aggregate slabs – it is clear that applying gas and oil resistant sealants provide numerous benefits ranging from improved aesthetic appeal to greater performance when compared to untreated surfaces.
With that said, it is essential to understand how certain types of sealant behave when they come into contact with harsh industrial chemicals – what level of protection they offer and how easily they can be uniformly applied. This will be discussed in further detail in the next section about ‘Protection from Harsh Chemicals’.
How Does A Sealer Work?
When it comes to protecting concrete surfaces, one of the most important components is chemical resistance. Exposure to harsh chemicals can be damaging for many surfaces, but particularly for concrete structures that are often used for storing and transporting combustible materials. Fortunately, there are a variety of sealers available that can protect concrete from the damaging effects of chemicals such as gasoline, oil, and other flammable liquids.
Proponents of using gas and oil resistant sealers to protect concrete point out that these products are specifically formulated to block the permeation of dangerous chemicals. They also note that their effectiveness increases with use over time, creating a long-term protection for any concrete surface subject to harsh chemical exposure. In addition, they point out that by applying a protective barrier on the surface of the concrete, it more easily withstands spills and regular maintenance procedures.
Critics argue that while gas and oil resistant sealers can be effective in preventing some types of hazardous chemicals from reaching the concrete’s surfaces, they often do not provide complete protection against all types of chemical exposure. For this reason, larger concentrations or more dangerous substances may still be able to penetrate the sealer’s barrier and cause potential damage.
Though there are both pros and cons associated with using a sealer to protect concrete from chemicals, it is clear that when used correctly it can offer added protection to many surfaces exposed to harsh compounds or frequent spills. Whether you are looking to protect a commercial building or your own home garage, investing in an appropriate gas and oil resistant sealer is one way you can help ensure long-term durability for your structures.
Now we’ll turn our attention to how these sealers work – both in terms of construction and ingredients – in the next section: How Does a Sealer Work?

Penetrating The Surface
When applying a gas and oil resistant sealer, one of the most important steps is adequately penetrating the concrete’s surface. Penetrating sealers are formulated to deeply penetrate into the pores of concrete and masonry substrates and chemically react with it. This reaction forms a durable protective barrier that blocks out staining agents from oil and gas from being absorbed.
Penetrating the surface correctly requires user comfort and knowledge of when to stop applying the sealer for fear of forming a film rather than penetrating. Once a “wet look” appears on the treated surface, it is past the point of penetration. Users should be aware of this to prevent any permanent damage or staining on concrete surfaces.
Furthermore, if penetrating sealers are applied too heavily or not given enough time to fully penetrate into the substrate, they may not bond correctly upon drying and can end up creating undesired cloudy patches instead of a consistent coating. It is always important to properly follow instructions when using any sort of masonry membranes as failure to do so could result in wasted material and money without gaining any benefit in performance.
Now that the importance of adequate surface penetration has been established, let us move on to understand how these sealers work to bond with masonry and substrate materials in the following section.
Top Takeaways
When using a gas and oil resistant sealer, it’s important to penetrate the concrete’s surface sufficiently to create a durable protective barrier against staining agents. Too much sealant or not enough time for penetration can lead to cloudy patches, so users should follow instructions in order to prevent any wasted material or performance issues. Properly penetrating the surface and forming a bond with masonry and substrate materials is key.

Bonding With Masonry And Substrates
The bond between the concrete and substrate, or masonry, is key to a successful topical or film forming sealer installation. Without proper bonding, it may be difficult to create an even layer and it can even lead to unsealing in spots that were not properly sealed. Many substrates and masonry materials will accept bonding agents, including Acrylics, Polyaspartics, Epoxies, and Acrylics with Silanes and Siloxanes.
Epoxies are known for forming strong bonds between different materials. They also provide good adhesion for a variety of concrete surfaces when used as a bonding agent. However, epoxy resin can come with its own set of complications if used incorrectly. If the temperature isn’t kept optimal during application or if the material does not cure correctly, sealing may be compromised.
Acrylic sealers are thinner and easy to apply when used as a bonding agent. Acrylic bonding agents usually require a curing period before being applied on top of a concrete surface, but they can provide an adequate bond once fully cured. Unfortunately, acrylic bonds may reduce the longevity of the sealer because it can separate from the concrete due to water absorbing into the material layers over time.
Polyaspartic sealers are extremely durable which makes them useful in extreme weather conditions and harsh UV exposure environments. Additionally, the product bonds firmly with most masonry surfaces making it ideal for absorbent substrates like brick and stucco. It is important to note that these bonds need to be supported by an appropriate priming layer and must be done so only after proper moisture testing has been accomplished as this can void warranties if done improperly or without caution.

Finally, Acrylics mixed with Silanes and Siloxanes are an effective sealant option thanks to their hydrophobic properties making them resistant to water absorption. When installed correctly, acrylics mixed with Silanes and Siloxanes create a great molecular bond between the substrate and sealer providing excellent adhesion and protection from weather elements. As with any bonding agent choice, it is essential that proper surface preparation takes place first which should include power washing prior to application for optimal results.
Bonding with masonry and substrates is an important step to a successful sealer installation on concrete surfaces and shouldn’t be taken lightly. Choosing the right bonding agent is key as each one has its own properties that offer varying levels of protection depending on the environment they will ultimately be exposed to. With that in mind, let us now explore how best to apply a sealer on concrete surfaces in the next section.
Applying A Sealer To Concrete Surfaces
Applying a sealer to concrete surfaces is an effective way of protecting against oil and gas spills. The application process is fairly straight-forward, but it does require some special tools, such as a roller or brush for larger areas. Additionally, for best results, the sealer should be applied to concrete that is completely dry and free from any dirt or debris.
Before actually applying the sealant, a quick test should be done on a small area of the concrete by pouring a few drops of water onto the area. If the water beads up and forms droplets, then there is no need to apply the sealer yet; however, if the water seeps into the concrete, it’s time to move forward with applying the sealer.
As with any product, there are two sides to the debate concerning applying sealants. One side suggests that regularly applying a sealer to the concrete will help guard against staining over an extended period of time, while also helping reduce cracking caused by freeze-thaw cycles. On the other side of the discussion, opponents contend that regular sealing isn’t necessary because properly cared for and maintained concrete will exhibit a high degree of resistance to both oil and gas spills without needing additional protection.
Regardless of which side you take in this debate, it is still essential for any homeowner who wants to protect their concrete surfaces to know what to look for in a resistant concrete sealer before making a purchase and beginning application. The following section will discuss this in further detail.
What To Look For In A Gas And Oil Resistant Concrete Sealer
When in the market for a gas and oil resistant concrete sealer, there are several qualities to consider. For starters, one should evaluate the product’s active solid content and ability to resist evaporation. This will ensure that the longevity of your sealant is well worth the cost. Additionally, it is important to make sure that any sealant is water based. Solvent-based sealers are moisture sensitive and may not properly bond to the concrete beneath it. Additionally, make sure that the sealant has superior water-repellency and resistance to alkali detergents and acids, as this will greatly improve its durability when exposed to various exterior elements.
Another quality to look for in a sealer is UV-resistance. Ultraviolet light from the sun is one of the most common causes of fading in paint and other coatings, so an adequate UV barrier should be included in any concrete sealing product. When evaluating products, it’s also important to consider repairing cracks in the surface before application. Most sealers will not provide adequate crack resistance. So they should be fixed first A crack in the seal can cause water infiltration which can lead to premature failure of the coating.
Finally, while a product may be certified as gas and oil-resistant, it is important to read through safety instructions to ensure proper usage and protection against hazardous materials. While many professional contractors might prefer a more generic solution, more specialized products offer increased protection against specific threats such as fuel spills, road salt corrosion and asphalt degradation due to engine heat.
While there are pros and cons associated with purchasing a specialized versus generic ready-made product when looking for a reliable concrete sealer, ultimately what matters most is finding one that meets your individual needs for protection (or lack thereof) from various hazards. And all things considered, maintenance and durability should still be top priority when making an informed decision about which product will best serve your needs. In the following section we’ll discuss what steps need to be taken to ensure durability and maintenance of your sealed concrete surfaces.
Maintenance And Durability
When it comes to protection and maintenance, concrete is a diverse material. For instance, many concrete surfaces are regularly exposed to elements such as heat, water, and oil which can lead to considerable wear and tear with time. In order to effectively protect concrete from such damage and extend its lifespan, it is important to use sealants that provide superior resistance against gas and oil. The effectiveness of any gas and oil resistant sealer largely depends on the quality of the product itself and its proper application.
The most common type of gas and oil resistant sealer that is used for concrete surfaces is polyurethane. This type of sealer offers superior protection against penetration by both gases and liquids, allowing for easy cleaning without causing any damage or discoloration to the surface. Additionally, high-grade polyurethane sealers also help keep a concrete surface protected from mold, mildew, and staining.
Due to their robust nature, polyurethane sealants are often preferred over other forms of sealing when it comes to durability. However, they do require regular maintenance in order to maintain their protected state or else they can start to become brittle or tarnished over time due to various environmental factors. It’s important to note, like all general purpose sealant products, it may lose some of its efficacy in harsher climates where temperatures are typically high.
On the other hand, acrylic coatings provide an additional layer of protection with less maintenance required as compared to polyurethane sealants. These coatings tend to be durable as well as more aesthetically pleasing and provide reasonable protection against oils and liquid spills with minimal loss of gloss over time. Unfortunately, acrylic coatings lack the same level of resistance toward gases which makes them a less ideal choice when dealing with potential petroleum-based contamination.
In conclusion, the best way for homeowners and business owners alike to ensure long-term protection for their concrete surfaces is by selecting a high quality gas and oil resistant sealer that meets their needs in terms of performance as well as longevity. Regular maintenance must also be done to ensure that the applied coat remains at peak efficiency throughout its lifespan. With this in mind, we now move into our conclusion in regards to protecting your concrete surfaces with gas and oil-resistant sealers.
Conclusion
When it comes to protecting your concrete from harm, a gas and oil resistant sealer like CoverShield U140 Matte is a must-have product. As discussed in this article, the benefits of using such a sealer far outweighs the cost of replacing unsightly, damaged concrete. The key feature of such a sealer is that it offers lasting protection against breaking, flaking, staining, oil and gas spills. This can provide an item of peace of mind for those who use their garage floor, driveway or patio on a regular basis. In addition, such products are designed to be easy to clean, meaning that they won’t require as much maintenance as other potential types of sealers would.
All in all, using a gas and oil resistant sealer is an effective solution to protecting your concrete surfaces. While this product might not be the most aesthetically pleasing choice, it is worth considering if you’re looking for long-term protection that doesn’t require frequent maintenance or repairs.
Ultimately, it will be up to you to weigh up the pros and cons depending on your individual needs and budget.

Frequently Asked Questions Answered
Before applying a gas and oil resistant concrete sealer, it is essential to thoroughly clean the concrete surface to be sealed. This means sweeping and removing any dirt, dust, grease, and loose materials from the surface in order to ensure that the sealer is able to bond onto the surface effectively. After cleaning, check for absorption. It the concrete is not absorbent it may be necessary to etch the concrete with a mild acid solution to create a rougher surface for better adhesion.
Once the surface has been prepared, the next step is to carefully apply the gas and oil resistant sealer. Make sure to use painter’s tape to mask off any nearby finishes or surfaces that you don’t want to get sealer on, such as wood or metal finishing. As you’re applying, pay special attention to drips or runs that can affect the overall finish of your project. Use a brush to evenly spread out the sealer, and if needed use a roller for larger flat surfaces. Be sure not to get too much sealer on your project since it will become difficult to work with once it starts drying.
Once you have applied enough sealer for your project, allow it time to dry completely. With some types of sealers this can take up to 24 hours for full curing and full protection. Check around for potential puddles or runs that need touch-ups after the initial application and make sure you let it dry properly before walking on it or using any furniture on top of it.
Finally remember if you don’t use a gas and oil resistant sealer then never to let gasoline come into contact with a SEALED concrete surface as this could cause staining and discoloration that cannot be easily removed without causing further damage to your concrete slab/surface.

Using a gas and oil resistant concrete sealer can have numerous advantages. First and foremost, it helps to proactively protect the concrete surface from deterioration caused by gas and oil spills. Gasoline and motor oil contain compounds that can be very corrosive when they come into contact with a concrete surface. These liquids can cause damage, staining, and even discoloration of the concrete if not sealed properly. The gas and oil resistant sealer will provide an extra layer of protection against any damage that these substances may cause.
In addition, the sealer will also help to reduce maintenance costs associated with the concrete surface in the long run. If a spill were to occur, the sealer could make it easier to clean up and prevent further damage from occurring. In many cases, using this type of sealer can also increase the life expectancy of the concrete. This is because it helps to create an impermeable membrane on top of the concrete which will protect it from wear and tear over time.
Overall, using a gas and oil resistant sealer can provide numerous benefits for concrete surfaces. It provides much-needed protection against potential damage caused by gasoline and motor oil; it reduces maintenance costs; and in some cases, it may even extend the life expectancy of your concrete surface.
There are several types of concrete sealers that are resistant to gas and oil. The most common type is an acrylic sealer, which forms a water-resistant barrier on the surface of the concrete while still allowing it to breathe. Acrylic sealers are easy to apply and relatively inexpensive, making them a popular choice for sealing concrete.
Epoxy sealers provide more protection than acrylic sealers but come at a higher price. They form a hard, durable and chemical-resistant layer on the surface of the concrete, protecting against both water and oil/gas residues. They are also more difficult to apply than acrylic sealers and require special preparation before use.
Urethane sealers provide excellent protection from moisture and chemicals, including gas and oil. They’re highly durable and long lasting, but can also be more expensive than acrylic. However they are less costly than epoxy sealers. Siloxane sealers are also quite effective in sealing against water and natural elements with excellent adhesion to the concrete. They don’t do well as gas & oil resistant sealers,. Additionally, Siloxane sealers can penetrate deeper into the surface than most other types of seals, providing better overall protection from damage caused by water and salt attack mold and mildew.

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

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.
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.
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.

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.
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.
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.

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.
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.
