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.
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 the application of DS160.
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.
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.
