Concrete Bathroom Floor Remodeling
Concrete bathroom floor refinished with white concrete overlay, stained with Black and Coffee Brown acid stains. Sealed with water-based acrylic sealer


My husband and I have wanted to do acid stain concrete for many years.  After much back and forth, we finally decided to use our master bathroom floor as a testing room if acid stain would be a true viable option for our entire house, instead of tile or carpet.  We had never done a project like this before.  We digested some informative articles and videos on your website and thought to ourselves, “Hey, this might be something we can do.”

We tried looking at other websites, and after hours of research, Direct Colors was the one that made sense, was most informative, and “how-to’s” were easy to follow. Next, we perused your many color options, and really fell in love with the cola and coffee brown combination.

Now, let’s get into the meat and potatoes of how we did it!

Pick a Room

We picked a room (our master bathroom floor which was previously carpet, GROSS!!!) that if our project was a complete failure we could use other options as a backup.

Bathroom Floor Clean Up and Preparation

  1. Removed carpet, carpet padding, and all the filth that came with it.  Yuck!
  2. Removed tack strips, after research we found out prying is not the way to go here, merely tapping away gently until it releases on its own, this seemed to do the trick.
  3. Start cleaning the bathroom floor…

Surface Preparation for Acid Staining Concrete Floors

We Found

• Glue residue (not actual carpet glue) – To remove we sprayed with water, let soak for about 10 minutes and used a sanding block to remove.
• Paint- Scraped thick paint off with razor blade.  We found that a belt sander with 80 grit sand paper was the quickest way to remove thin or over spray paint, however it was very messy.
• Carpet glue -We also used the belt sander on carpet glue as well.

After all the paint and glue were removed from the concrete, we wiped down the entire bathroom floor with an organic degreaser and water solution to remove any remaining residues. We protected the walls from acid stain over spray with contractor’s paper and painter’s tape.

Now for the FUN part… Acid Staining the Floors


 After inspecting pieces of granite, I decided on an application pattern I wanted to replicate with Concrete Acid Stain.

I used Coffee Brown to start with for the darker areas.  I then took Cola and went around the edges of the dark areas.  I then took more Cola and mixed it 1:1 with water, and used it on the outlying areas of the full concentration Cola.

Finally, I used 1:2 to fill in the remaining untouched concrete areas, and allowed it to dry completely. By using this process, I was able to navigate throughout the room stepping on the untouched concrete areas.

We neutralized with baking soda and water (2 tbs. of baking soda per gallon of water) and applied it using a mop allowing the bathroom floor to dry completely.  Then we used a sprayer with the same baking soda solution. We then mopped the floor several times until our water was clean and allowed to dry.

We sealed the bathroom floor using Direct Colors Water Based Polyurethane.

“Et viola!  Thank you to Direct Colors for providing the tools and resources for us to complete a project we would have never dreamed possible with amazing results. The prep work is the most challenging part but well worth it in the end, we were so excited after finishing the master bathroom floor, that we have since completed our master bedroom, with plans to finish the entire house.”

Thank you,
