Application

Installation Guidelines

New Concrete

CoverSeal DS160 can be applied to green concrete when the concrete is strong enough to be walked on without leaving a mark, typical 2 to 3 days.

Existing Concrete

The surface must be clean and porous enough to allow penetration into the substrate.

Surfaces should be clean and free of surface laitance, dust, dirt, debris, mildew, oil, grease, previous sealers, curing agents, paint or other surface coatings, and other contaminants. If acid or other cleaning compound is used for cleaning or etching the surface, neutralize the surface completely before application of DS160.

Test Area

Before application to the whole surface, test a small area to verify absorption, application rates and desired results especially on dense surfaces.

The concrete must be dry prior to treatment.

Stir DS160 thoroughly before use. Substrate and ambient temperature should not be below 40°F or above 95°F during the application or drying period.

Apply an even layer of product with a low-pressure sprayer, lamb’s wool applicator, roller, or brush.

Work in small, manageable areas to ensure the product is applied uniformly and does not dry out on the surface.

Allow DS160 to fully absorb into the surface for 10 minutes without puddles.

Any product not absorbed after 10 minutes should be spread using a soft broom, roller, or lamb’s wool applicator.

Over-application may leave a white residue on the surface. This residue can be cleaned off when dry by scrubbing or by pressure washing. 

Applying DS160 to a surface that has low pH content may also lead to the formation of white residue. To reduce this likelihood, it is recommended that the surface is rinsed thoroughly with water 2 hours after final application of sealer.

One or two coat application is typically required.

Very porous or dusty surfaces may require a second application. Localized areas may require a second application.

If the surface is porous and more product can be absorbed, wait 1-2 hours before the second application following the same method described above.

DS160 is recommended for used as a primer for any of CoverTec’s stain resistant sealers to maximize the durability and effectiveness of the stain proofing.

Water Vapor Emission Testing

Before surface coatings, paint, floor covering etc. are applied over the DS160 treated concrete it is important to test that moisture level is within acceptable limits according to floor covering manufacturer’s warranty. Test the concrete to determine the moisture vapor transmission rate (MVER) using the ASTM F1869 anhydrous calcium chloride test.

Vertical Surfaces

On vertical, formed surfaces, apply DS160 as soon as the forms have been stripped and the surface rubbed, (if required). Apply from the bottom up, going over the area twice to ensure saturation. Pay attention to the quantity of material applied by square footage (square meter). You should apply one gallon to every 200 ft2 (1 liter/ 4.9 m2) of wall surface. Do as many light applications as required to result in that application rate.

Limitations

  • Do not apply to wet surfaces.
  • Do not apply below 40°F or above 95°F (5-35⁰C)
  • Allow grout and mortar to fully cure before application This product is not a “ topical sealer” and will not prevent staining. Use CoverShield products if you wish to seal and protect from staining.
  • Do Not Dilute Ready-To- Use Product.
  • Will not accommodate dynamic movement cracks.
  • DS160 is designed to work only on porous natural stone and concrete is not intended for asphalt.
  • The use of high alkaline or acidic cleaners on the treated surface is not recommended and can be damaging.

Frequently Asked Questions

When should you densify concrete?

Densification is typically performed when the concrete has cured but is still fresh, usually after the initial set. This timing allows the densifier to effectively penetrate the concrete surface and react with the calcium hydroxide to strengthen the concrete matrix.

 

What is the best concrete densifier? Several high-quality densifiers are available in the market, offering different formulations to cater to specific project requirements.

Factors such as the desired outcome, concrete type, and environmental conditions should be considered when choosing the best concrete densifier. Consult with CoverTec to determine the best densifier for concrete floors and achieve optimal results.

Is densifier the same as sealer? No, densifiers and sealers are different products with distinct purposes. Densifiers penetrate the concrete surface, reacting with the calcium hydroxide to strengthen the concrete matrix. They primarily focus on enhancing the concrete’s strength, durability, and resistance to abrasion. Sealers, however, create a protective layer on top of the concrete, primarily to prevent moisture penetration, stains, and chemical damage.

How deep does concrete densifier penetrate? The depth of penetration of a densifier depends on several factors, including the type of densifier and the concrete’s porosity. In general, densifiers can penetrate several millimeters into the concrete surface, reacting with the calcium hydroxide to form calcium silicate hydrate, which fills the pores and increases the concrete’s density.

Does densifier darken concrete? The effect of a densifier on the concrete’s appearance can vary. While some densifiers may darken the concrete slightly, others are designed to have minimal or no impact on color. It is important to consider the desired aesthetic outcome when selecting a densifier. Conducting a small test area before full application is recommended to evaluate the effect of the specific densifier on the concrete’s color.

What is the difference between concrete hardener and densifier?

Although the terms “hardener” and “densifier” are sometimes used interchangeably, they serve different purposes. A concrete hardener densifier is a surface treatment that forms a protective layer on top of the concrete, primarily focusing on enhancing surface hardness and abrasion resistance. On the other hand, a densifier penetrates the concrete, chemically reacting to increase the density, strength, and durability of the concrete from within.

Densifier for Concrete: Enhancing Strength and Durability

The Revolutionary Role of Reactive Penetrating Densifiers

With concrete being a vital component in construction, the importance of its longevity cannot be overstated. As concrete protection experts, we at CoverTec have been focusing on a groundbreaking solution redefining concrete protection – using a reactive penetrating densifier for concrete as a primer for concrete sealers and coatings.

Concrete: More Than Just Stone and Cement

When we think of concrete, we tend to picture a grey, dull material. But there’s more to it! Concrete is porous, intricate and needs protection from the elements to prevent degradation and preserve its structural integrity and appearance.

So, what’s the key to safeguarding concrete? Let’s dive in!

Concrete Sealers: The Conventional Route

Sealers have been the go-to solution for concrete protection. By creating a protective barrier, they repel water, resist stains, and shield against deicing salts in frigid conditions. However, while effective on the surface, they don’t penetrate deeply into the concrete to offer thorough protection.

What if we had a product that could act as a sealer and also infiltrate deep into the concrete? Here’s where the real game-changer comes in – the reactive penetrating densifier.

Unveiling the Reactive Penetrating Densifier as a Primer for Concrete Sealers and Coatings

Reactive penetrating densifiers are innovative substances that chemically interact with the concrete upon application, resulting in a denser, harder surface. This effect reduces concrete’s porosity and enhances its resistance to wear and tear, rendering it ready for the application of sealers or coatings.

How does this chemical interaction occur, you ask? Let’s delve into the specifics.

The Chemical Intricacies of Reactive Penetrating Densifiers

The underlying science of these densifiers is intriguing. Reactive penetrating densifiers comprise compounds like silicate, which reacts with free lime or calcium hydroxide present in concrete. This reaction forms a new, insoluble compound known as calcium silicate hydrate (CSH), which fills up the pores in the concrete, making it denser and less permeable.

Perks of Opting for Reactive Penetrating Densifiers

You might be pondering, “What’s in it for me?” The benefits are numerous!

  1. Enhanced Durability: By densifying the concrete, the material becomes more resilient to wear and tear and can withstand heavy traffic.
  2. Aesthetic Improvement: As the densifier decreases the concrete’s porosity, it lowers the likelihood of staining and discoloration.
  3. Preparation for Additional Protection: The densifier is an excellent primer, readying the surface for sealers or coatings application.

Sealers and Coatings Application Following Densification

Once the densifier has been applied, the concrete is primed for further protection. The type of sealer or coating to be applied will depend on the specific requirements of the concrete, such as the level of protection needed, desired appearance, and more.

Preserving the Protected Concrete: Guidelines

Maintaining the densified and sealed concrete is just as critical as the initial treatment. Regular cleaning, avoidance of harsh chemicals, and routine inspection form part of an effective maintenance routine.
