During the 80's Gypcrete became popular because it was fire resistant, light weight and it did not corrode copper tubing used for radiant heat. It is typically white compared to grey concrete and usually has a dusty surface. It is very difficult for most paints to bond to this material and requires a special primer. Unfortunately, the only primer we've ever found for this type of concrete is full of toxins. The best way to know if our AFM Concrete paint (formerly Deckote) will bond properly is to order a small sample and test it out: https://www.greenbuildingsupply.com/A... If your subfloor is not Gypcrete, then as long as it is clean, dry and free of grease, oils or wax, the Concrete Floor Paint should work well. Two coats are required. It has very low odor which dissipates quickly.
