For a beautiful transformation, come learn how to paint concrete floors. It’s amazing the difference that some paint and elbow grease can make!
Hi! I am thrilled to share how to paint a concrete floor! Here’s a before and after of my concrete mudroom floor:
So much better, right?!? Here’s the process for how to paint a concrete floor:
Step 1. Clean and Etch
Our first step was giving it a good scrub down, followed by etching. You need to etch the concrete to give the porch or concrete paint a good surface to adhere to. This keeps the paint from flaking off immediately. I used a long-handled shop broom to scrub the floor. Directions vary from product to product, so follow the directions for the cleaner you choose. We used Valspar Fast Prep, which is a premixed degreaser and etcher in one.
Step 2: Paint first color of concrete floor paint
After allowing our floors to completely dry, I put a coat of pure white porch/concrete paint on all of the concrete surfaces. Don’t bother with a paint tray for this, I just poured it out of the bucket as I went, then rolled it smooth.
Step 3: Draw your pattern and tape the lines
After waiting for the paint to cure (I only waited two days, but I should have given it more time. I ended up causing myself more work! Check the directions on your can of concrete paint), draw your lines using a pencil, a level, and a tape measure. I started on the far wall, and measured the starting lines for the points of my diamonds. My diamonds are 22 inches long, so I marked each spot. After that, it was simply a matter of measuring and drawing. This is tedious! Then, on to taping. I used Frogtape for delicate surfaces, and I put my tape on the outside edge of only the diamonds that I was planning to paint gray. I used a putty knife held at an angle to give myself a good clean edge when I tore my tape off.
Step 4: Paint second color of concrete floor paint
I used a foam roller to get a nice even coat of my gray paint (the color is New Concrete by Valspar). I gave the gray diamonds two coats each and used a paint brush to do the edges next to the tape. While my paint was still wet, I started pulling off the tape. Remember how I said two days curing time wasn’t enough? This is why! I had to go back with a paint brush and touch up ALL the edges. Frustrating!
