1. Determine why your concrete floor is damp. If the dampness is an ongoing problem, you may need to undertake structural repairs, or repair any leaking appliances . If the dampness is not an ongoing problem, wait for the concrete to dry thoroughly before attempting to paint it.
2. If your concrete floor is old or stained, clean it thoroughly with a solution of tri-sodium phosphate before sealing it.
3. Seal the concrete. Use one of the floor paint rollers to spread a thin layer of sealant over the concrete floor. Wait at least 24 (and preferably 48-72) hours for the sealant to dry as much as possible.
4. Prime the concrete floor with damp concrete primer. Make sure that the product is specifically made for damp concrete floors. Use the floor paint roller to spread a thin layer of primer over the entire floor. Wait 24 hours and give the floor a second coat. Wait 48 hours before proceeding.
5. Paint the concrete floor using concrete floor paint. Make sure that the paint is specifically made for floors, as normal latex paint will produce a slippery finish, especially on floors prone to dampness. Use a third floor paint roller to spread a thin coat of floor paint over the concrete floor. Wait 24 hours and apply a second coat.
For the first step be aware, you have to wait 24 hours and look under the plastic. If the plastic and the floor below it are dry, then proceed. If not, try putting a dehumidifier or desiccant material in the area to reduce the amount of ambient moisture in the room and repeat the test again.
