How to Paint a Floor

Painting a floor is a great way to refresh a tired space and add durability underfoot—especially in garages, laundry rooms, and basements. But floors take more abuse than walls or ceilings, so proper prep and the right paint are key to a long-lasting finish.

Here’s how to do it right.

What You’ll Need:

• Floor paint or epoxy paint coating
• Concrete or wood floor cleaner/degreaser
• Sandpaper or concrete etching solution (if needed)
• Paint roller with extension pole
• Angled sash brush for edges
• Painter’s tape and drop cloths
• Primer (if required by your coating)
• Floor patch or filler (for cracks)
• Safety gear (gloves, mask, eye protection)

Step 1:

Clean and Prep the Surface

Start by removing any furniture, rugs, or obstacles. Sweep thoroughly, then clean the floor with a degreasing cleaner to remove oil, dirt, and residue. For concrete, the best prep is our On-Floor grinder or to use a specialty cleaner or etching product.

If you’re working on a wood floor, lightly sand the surface with 120–150 grit sandpaper to dull the finish and help the paint bond.

Step 2:

Repair Any Damage

Patch cracks or holes using a floor filler designed for your surface (concrete or wood). Allow it to dry fully, then sand smooth. This step ensures a level surface and prevents your paint from wearing, cracking or peeling prematurely.

Step 3:

Prime (If Needed)

Some floor paints are self-priming, but not all. Check your product instructions. If priming is required, apply a suitable primer using a roller, and allow it to dry thoroughly—typically 4 to 6 hours.

Step 4:

Paint the Edges

Use painter’s tape to mask off baseboards or walls. Then, use an angled sash brush to paint a clean line around the perimeter of the floor—this gives you a crisp edge and easier access when rolling.

Step 5:

Roll the Floor

Pour your floor paint into a tray and load the roller evenly. Work in small sections, using long, even strokes. Roll in one direction for consistency, and avoid going back over areas that have started to dry.

Allow the first coat to dry fully, then apply a second coat for added durability and better colour coverage.

Pro Tip: Avoid walking on the floor between coats. Use boards or cardboard to step on if necessary.

Step 6:

Let It Cure

Even if the paint feels dry to the touch in a few hours, most floor coatings require 24–72 hours to fully cure—especially for heavy furniture or foot traffic. Check the label for specific cure times before moving everything back in.

A Smooth Finish That Holds Up

With the right products and prep, painted floors hold up beautifully against foot traffic, water, and wear. Plus, they’re easier to clean and maintain than unfinished surfaces.
