If you need to paint a concrete surface, you need to paint it the right way. When painting concrete, it's important to remember, concrete can be slippery when wet. Consider incorporating an additive to combat the slick surface. Always wait 3 to 4 weeks before painting new concrete.
Things You Will Need
Apply cat litter to grease or oil stains. Allow it to sit overnight. Sweep away cat litter and all surface dirt and dust with a stiff broom.
Wash your concrete with detergent and hot water. Scrub the entire surface with a stiff broom.
Rinse the concrete at least twice. If you have any remaining stains, use muriatic acid. Wear protective clothing, safety glasses, gloves and a respirator when working with it. Use extreme care when handling and using muriatic acid. Muriatic acid is available in hardware stores and home improvement stores.
Allow the concrete to dry completely. Use paint made specifically for concrete such as an alkyd enamel. This type of paint is very durable, but slippery when wet. There are other types of concrete paint and additives which will "rough" the surface. Never use latex paint because latex will peel away especially if it comes in contact with tires due to a chemical reaction.
Use a large floor roller to apply your paint or if you are experienced with a sprayer.Painting a concrete floor can really bring back the life to it. Do it right the first time so that you are not repainting your floor in a short amount of time.
