How to Paint New Concrete Floors

Updated February 21, 2017

Concrete floors are very susceptible to moisture creeping up through the concrete. Applying a good sealer and paint will not only seal the floor, but add years of beauty to your new concrete floor. Paint for concrete floors is available in a wide array of colours and textures depending on your specific project needs. Once complete, your concrete floor will not only look better, but will stand up to daily traffic as well.

Sweep the floor clean of any dirt, sand or debris.

Clean the floor as needed to remove any concrete residue or film from the surface of the newly poured concrete. Use either the TSP solution or a citrus-based solution to pour on the floor, and lightly scrub to clean or etch the floor. This will remove the residue that might prevent the primer and paint from adhering to the concrete surface.

Clean away the TSP or etching solution from the floor using the mop and bucket of water. Allow the floor to dry completely.

Vacuum the floor thoroughly to remove any residual powder left over from the TSP or etching chemicals. Make sure the concrete floor is completely free of any debris.

Apply the primer, using the roller, by starting in a far corner away from a door, and rolling it evenly. Apply an even coat as you work your way back to the door or room opening. Allow the primer to dry, following the manufacturer guidelines, which is typically overnight or a 24-hour time period.

Start in the same corner as you did when applying the primer and begin rolling on one coat of paint/epoxy at a steady pace. Use the paint brush to trim around any areas in the room that abut the floor. Allow the first coat to dry overnight, and apply a second or third coat as needed.

Use the mineral spirits to clean any paint drips, as well as for cleaning the paint brush and roller.

Apply a sealer if desired for your project. Begin in a corner opposite the door and once again roll the sealer over the paint/epoxy in an even coat. Work your way to the entrance of the room, until the entire floor is covered. Allow this coat to dry overnight.


Most concrete paints/epoxy comes with a sealing chemical already mixed in so depending on your need, you may not need to apply a separate sealer. Also it is helpful to remember that should the paint/epoxy become scuffed, it is more difficult to touch up and adhere new paint to existing paint with a sealer coat on the floor. Use of a citrus-based etching chemical is less abrasive to the surface of the concrete and less likely to make it more porous.


Avoid direct inhalation of the paint fumes or mineral spirits as this could lead to internal injuries. Use only in a well-ventilated room.
