When you decide on painting concrete floors, the process can be either a basement project or garage floor job. Concrete is well suited to be painted, as long as certain procedures are followed and the proper products are used.

On this page you will find information and how to advice for painting your concrete floors.

Prior to to getting those floors coated, talk to your local paint supplier or home improvement dealer, regarding the tools or products that you will need and application advice for the job at hand.


Below are a list of products and tools that you may need, (depending on your project) to help you with painting concrete floors.

Cut can and 2 1/2" sash brush.
Roller/cover, tray, extension pole.
80 to 120 grit sand paper, pole sander.
Caulking/gun, fillers (paintable).
Painters tape, duct tape, plastic, masking, etc.


Use primers and paints that are recommended for coating concrete. Coatings used, should also be of the highest quality. Cheaper coatings will not, in most cases adhear well to high traffic area like floors.

Alkyd, latex, flat, semi gloss, epoxy, what you use, depends on the floor project being done and the amount of money your willing to spend.

Talk to your local paint supplier for product advice.


Every concrete floor is different. Some floors have been painted before and are in excellent shape. In such cases little prep is needed, unless the floor is shinny, then the shine must be removed by either priming the floor or sanding the finish until the shine has been removed.

New or very dirty floors will need to be acid etched prior to coating. Talk to your local paint dealer regarding acid etching and painting concrete floors.

Old flaking or peeling paint, and raised bumps and imperfections need to be scraped off, then sanded with 80 or 100 grit sand paper.

Holes, divots and cracks need to be filled with paintable fillers that are made for concrete then left to dry. Some areas may need to be refilled as fillers can shrink and crack.

Wet or damp concrete must be thoroughly dried out before painting concrete floors. To check for dampness, tape 6" by 6" squares of plastic on the floor leave the plastic on for 24 hours or so then check the plastic regularly to see if there are beads of moisture on the plastic.

If you see moisture don't apply paint. Keep in mind, brand new or damp concrete depending on environmental conditions, can take a month or more to dry out.

Oil and grease on a concrete floor must be removed before paint stick to it. A degreaser normally used to clean car engines can work but I have found that if a floor such as that in a garage has fluid, oil or grease stains they don't always come out and in some cases will not even let an epoxy paint stick.

Unfortunately, the only way to find out how well your paint job is going to work is to do it.


If you would like to jazz up your concrete floor, then try one of these design ideas. As a tip, draw your design on paper so that you can see how different ideas work then using flat paint apply your design in layers once its dry coat the hole floor with a sealer.

Talk to your local paint supplier, regarding the best sealer to use for your situation.

Faux finish.
Wall decorating technique (e.g. stripes, color blocking, splatter).
Geometric shapes.
Cartoon caracter.
Theme (African, cityscape, ocean, etc).
Stone, brick, tile, marble.


Before you begin painting concrete floors, keep in mind that the entire process can take more than a day or two. If you need to use your floor then hold off on applying until a time when your not having to walk on the floor for up to a week (depending on your project).

A paint sprayer can be used but before doing so, be sure you have a good understanding of your sprayer. If your not spraying, a brush and roller with an extension pole will work just fine.

The procedure below is for a raw unpainted concrete floor. If the floor has been painted before and is thoroughly sanded (shine removed) then only two coats of paint (depending on color) should be needed.

1. With a brush and cut can 1/3rd filled with your coating, cut in the floor around the room, were the roller isn’t going to be able to get at.

2. Using your filed paint tray, roll on your coating in sections, the same way you would roll a large wall. The difference between a wall and floor is, with the floor you don’t want to paint yourself into a corner.

3. Once the coating is dry, fill any cracks or holes that show up with filler, let them dry, the spot prime with the coating your using, let that dry.

4. Now, lightly sand the floor with the use of a pole sander and 120 grit sand paper. With the primer done you can start painting concrete floors.

5. Finally, cut and roll on two more coats of paint, making sure to sand between coats. At this point the sheen of the paint depends on whether your going to draw on a design or not.

When buying your paint, talk to your local dealer for product, tool and application advice regarding the project being done.

6. With the floor painted, you can if you want, begin layering on any design you like. After your design is done and dry, apply a coat or two of clear sealer.
