Huber Residence, Birmingham, MI
This is the garage of a new home in Birmingham, Michigan. The homeowners were so pleased with the job we had done acid-staining their basement floor that they asked us if we could do the garage the same way - they didn't want the synthetic look of the traditional epoxy color flake system that is done in most garages.
We had acid-stained their basement floor a dark brown, almost black color, and we used the same color - Brickform's Ebony - on the garage floor. We had to be careful, though, because the concrete was sloped toward the sewer grate in the middle of the floor. To prevent the stain from running, we applied 6 very light coats instead of 2 normal coats.
Despite being a new garage, the floor (above left) still needed a great deal of cleaning, and there were a lot of unsightly saw-cut joints. So prior to staining, we spent a few days cleaning, sanding and scraping the floor, and filled the saw-cuts, and a large crack around the sewer grate, with a dark brown polyurea joint filler (above right) to blend with the acid stain.
We then applied the acid stain with a 2-gallon, acid-resistant pump-up sprayer. The photo above left shows the color of the floor immediately after applying the 6 light coats of stain. The photo above right shows the color of the floor after the stain was allowed 12 hours to react with the concrete, and the excess stain residue was rinsed.
The final color of an acid-stained concrete floor rarely looks the same before and after applying the sealer. Though the acid stain only reached a dark brown hue after staining, we knew the sealer was going to darken and enhance the depth of color to look close to black. Above left, you can see the sealer being applied. Above right, you see the finished product.
Here are two last photos of the floor. We applied 3 coats of a clear, gloss polyurea sealer to protect the acid-stained concrete. Included in the sealer was a glass bead additive for slip resistance. Notice how the numerous, unsightly saw-cut joints at the outset of the project have just disappeared, making the floor look line one, monolithic uniformly colored slab.
