Coval Primer is a fast-drying, acetone-based acrylic sealer designed to fill in the pores of the concrete prior to applying Concrete Coat. When the Concrete Coat is applied, it will incorporate the acrylic into the coating and bond to the concrete surface as one. This will also reduce the amount of Coval Concrete used because you are not losing material that is seeping into the surface pores. Concrete Primer is also used for porous stone and masonry surfaces to seal the interior pores before sealing with Concrete Coat.
Do not over-apply. The Primer is an acrylic. When the Concrete Coat is applied it will re-emulsify this acrylic into the coating. If you overapply the Primer, then it will create a barrier that can prevent the Concrete Coat from bonding with the surface and will peel off. Once you can see that the primer is not being absorbed by the concrete then stop applying.
This should NOT be used on polished concrete or any other non-porous surfaces. If you can see a white residue, then you have applied to much. Remove using an acetone-soaked rag or microfiber and start again.
HOT TIRE PICKUP:
If you are coating a garage floor where there will be hot tires, then you need to make sure you are getting a good bond with the floor. Over-application of the primer on garage floors will result in delamination due to hot tires. We recommend reducing the volume of Primer when coating garage floors or driveways.
