After ripping out the carpet, we were left with a plywood subfloor. Luckily our plywood was in decent shape and not OSB.

OSB is the stuff that looks like chips of plywood have been glued together to form a sheet. You can paint OSB, but you will still see the chipped wood texture beneath it.

If you’re wondering why on earth we are painting our plywood floor, I got carried away with a room makeover and decided that I couldn’t stand to have carpet for one second longer.

We painted the plywood floor because I was convinced that I could make it look good. And I did! I can’t wait to show you how it turned out.

Be sure to check out how we painted a checkerboard pattern on the floor!

How to Paint a Plywood Floor

Supplies Needed:

• Paintable Caulk
• Primer
• Floor and porch paint
• Paintbrush
• Roller (we used an 18″ roller to get the job done faster)
• Roller frame
• Paint bucket (if you get an 18″ roller, you will need one that is large enough)
• Polycrylic in satin

Notes About Supplies

Primer. Although we skipped the primer, I highly suggest using a primer. Not only does it make the paint stick to the floor better, but it will also prevent the nailheads from discoloring the paint finish. It also helps you use less paint since the raw plywood soaks paint up. Since primer is cheaper than paint, I like using it instead for that initial coat.

Floor and porch paint. Don’t try to use regular latex paint for painting floors. The paint will peel up eventually. We used Valspar paint matched to Sherwin Williams colors. Since I skipped the primer, this room took about 1 1/2 gallons of paint. (This room is 12′ x 25′.)

18″ Roller. We used a giant roller to make painting the floor faster. I highly recommend doing this. We used this when we painted our deck as well and loved how fast it went.

If you use the same roller frame that I recommend, be sure to turn the roller upright when you’re tightening the bolts. This lets gravity force it to push down so that it is nice and secure. It’s a pain when it pops out because it’s not secure, but this method makes it work correctly.

Prep Work for Painting a Plywood SubFloor

1. If your floor has any splintered parts, it will need to be sanded. I didn’t sand the whole floor, just the rough spots. Pay close attention to the edges of the wood.
2. Clean your floor well. I vacuumed up the dust and then I mopped the plywood. It was just as hard as it sounds.
3. Let the wood dry.
4. Use paintable caulk to fill any seams of large gouges. (These areas will show up if you use light-colored paint.)
5. Let the caulk dry.
6. Apply primer to the wood.
7. Paint around the edges of the room with a paintbrush.
8. Use a roller to get the center areas, making sure you back yourself out of the room as you go.
9. Let the primer dry.
10. At this point, only enter the room wearing clean socks. Bare feet and shoes will mess up the paint. (Don’t worry, it will dry and be strong!)

Painting the Floor

1. Use a paintbrush to paint around the edges using floor and porch paint.
2. Use the roller and paint the center of the room, walking your way out of the room as you go.
3. Let the paint dry.
4. You will need 2-3 coats of paint, depending on the color. We used Sherwin Williams Passive (a light gray.)
5. Apply 2-3 coats of polycrylic to protect your floor.
6. Try to let the paint dry for about 12-24 hours before replacing furniture. We had to paint the walls still, so they had plenty of time to dry.
