Hi Jeremy. Assuming the coating is still in good shape, you can apply an equivalent or higher-quality clear coat with an anti-slip media mixed in. This article here discusses how to use anti-slip media. It would require that you first degrease and then rough up the current coating with 120-grit sandpaper to prep for the additional coat. Garage floor coating companies can do this for you or you can do it yourself.

Hi Christy. Hopefully, Tom can back to you. In the meantime, Rust-Oleum has created a new product that you can use on their garage floor paints (not coatings). It’s called Rust-Oleum Clear Finish Topcoat. You can find it here on Amazon. Some home improvement centers are beginning to carry it as well. It’s a water-based acrylic clear coat with a gloss finish that is compatible with paint (not coatings). It won’t make the paint color glossy, but the finish of the clear coat is. We do not recommend the garage floor paint or the clear topcoat if this is for a garage with vehicle traffic. It’s not a long-lasting flooring solution and you will experience hot tire pickup (peeling) where the car tires sit. It does not matter what the marketing on the can says – it will happen. If it’s for foot traffic only, then this combination will work fine. This article hear discusses applying clear coats to paint. In addition, this article here discusses the differences in paint vs coatings so that you get a better idea of what you are purchasing. I hope the additional information helps.

Tom, did you find a solution to this? We just purchased the same paint+primer and was surprised at the dull finish as well. Looking for a top sealer.

Hello Jim and thanks for the kudos. I think you are overthinking this. A 40 mesh fine grit anti-slip additive will work well in a polyaspartic or polyurea top coat. It’s a fairly standard application that the pros incorporate into their floors. If you were applying it in a 100% solids epoxy, then you would have issues of it sinking below the surface before the epoxy cured enough. And yes, you can apply polyurethane over polyaspartic, but it is not recommended. Most polyaspartic coatings perform slightly better than polyurethane.
