Hello Mathew. The potential problem is how well the EpoxyShield Clear Coat has adhered to the RockSolid color base coat. According to Rust-Oleum, EpoxyShield and RockSolid should not be applied over each other during the recoat window due to compatibility issues. Applying RockSolid Clear Coat over EpoxyShield just doubles the problem. We recommend contacting Rust-Oleum Customer Support for guidance.

Hi,

I just laid the Rock Solid Polyacuramine in my garage with the flakes then used the Epoxysheild and anti skid not realizing the Epoxysheild clear coat was a different product? Can I apply the Rock Solid top coat over the Epoxysheild top coat now? What’s the best way to handle the situation without ruining the flakes and Rock Solid Polyacurmine that was just applied? It’s been less than a week and no cats driven on surface yet

Hi Wendy. Coatings don’t tolerate moisture from under the slab very well. Particularly if it’s enough for water to pool. This can be fairly typical in basements and why coatings are not always a good choice. If you apply a coating, chances are it will peel up during the rainy season due to the moisture. If you still like the idea of a coating, it’s extremely important to moisture test before you apply it. Again, the best time to moisture test is during the wet season.

We recommend covering the concrete with a breathable flooring surface. Interlocking tiles are an example. They will allow for air circulation under the tiles. This allows moisture vapor to pass through and will help to keep the concrete dry. We have an article here that discusses what you should know about interlocking tiles, including the pros and cons.

Hi Dave. Yes, an area that receives only foot traffic would be considered a candidate for the recoat primer. If it was a garage where cars are parked, we would not recommend applying it over paint since hot tires could peel underlying paint up. Our only concern would be moisture from the basement floor. Paint breathes and will allow some moisture vapor to escape. Coatings such as RockSolid does not breathe and will trap it below the coating. This can lead to the coating peeling at some point in the future. Has a moisture test ever been conducted? Does it ever humid in the space or do you have to run a dehumidifier?

Assuming there are no moisture issues, we recommend taking a paint scraper to the surface to remove any loose paint that may appear adhered. Especially the edges where the bare concrete is. Scuff up the bare concrete with 100 grit sandpaper and then degrease. Wait a few days or so for the surface to dry before starting with the recoat primer. Coatings do not do well with water vapor that is still evaporating from within the concrete.
