Painting cement floors is an affordable home improvement that can give an interesting look to a room in a few days. Compared to installing wood floors, tile or carpet, painting a cement floor can be done for a fraction of the cost and requires less work. With proper preparation of cement before painting followed by careful application of all materials, an ordinary cement floor can be transformed into a design element to complement any room.
Thoroughly clean the cement surface. Clean any substance or material that is stuck to the floor with the spatula and sweep the floor completely. The home improvement website recommends removing any oil or grease from the cement by applying cat litter and a hard bristle brush to rub the area with trisodium phosphate (TSP). Rinse the floor and let it dry for several days.
Repair cracks or gaps by applying patches for concrete or using hydraulic cement. Use the brush to apply the adhesive into the crack or hollow before applying the concrete patch mixture to the area, according to Dixieline ProBuild. Use a metal spatula to soften the concrete patch and let it dry according to the manufacturer’s instructions.
Glue the tape to paint the bases around the perimeter of the room to protect it from primary paint, paint and sealant.
Apply the primary paint for cement. Ask a professional in a store for the right type to use on cement floors. Use the roller to apply the paint to the entire surface and let it dry for the time indicated by the manufacturer.
Use a clean roller with a long handle to apply paint to the floor in thin layers. Home Improvement recommends applying two to four layers for durability and a more consistent color, allowing the floor to dry between layers.
Apply the sealant to protect the floor. Apply the roller to the entire surface of the cement floor. Use a mask to avoid inhaling gases. Apply a second layer of sealant after the first one has completely dried.
Tips & Warnings
- Use primary paint and paint in a well-ventilated room to avoid inhaling gases.
- Ask a professional to make sure the paint is compatible with concrete and consider floor additives to make the surface less slippery.
- Use a mixture of concrete patches prepared for minor repairs.
- Use a brush, not the roller, to paint the floor around the bases.
- Use a clean and new roller when applying primary paint, paint and sealant.
- Always start painting at the farthest point of the door and do the work in the direction of the exit to avoid getting trapped in a corner.
