Marbled Granite Look with Direct Colors Concrete Acid Stains
The marbled granite look is probably our most popular how-to application request. Tina N. supplied with an excellent description of her acid stained patio project that should give any home or business owner what they need to know to duplicate her results.
“I recently stained the concrete on my back porch, which had been covered in green outdoor carpet for about 30 years. After much elbow grease and with the assist of your Bean-e-doo product, I was able to apply your Desert Amber, Cola, English Red, and Sea Grass concrete acid stains. Good floor prep can’t be emphasized enough. We had old astroturf glued to the concrete. After several passes with a scraper, Bean-e-doo, and the use of a floor sander, the concrete was ready for stain. This process was definitely more work and took twice as long, but would not have yielded our final result had it been skipped or abbreviated.
A manageable sized section at a time was worked, blending the next section in as the work progressed. All 4 colors were in their own sprayer and used concurrently. First the concrete was dampened with water. Then Desert Amber was used as a base color. On top of that, Cola and English Red were applied making sure to duplicate the graining pattern like that in marble and always blending with the next section to continue the look. Sea Grass was added as a highlighter to the pattern. Leaving areas with the Desert Amber exposed is important to the look.
A good amount of all the colors were used, thoroughly saturating the concrete with the stain. This ensures you get enough color down, and helps the colors flow better. It’s not important to have an exact idea of how the whole project will look in the end, but you should have a general idea of how the graining pattern should flow.
It’s difficult to imagine the final version anyway, because the actual color of the stain is one color going on and turns to the final color later. On this project, the porch was installed when the house was built and has a slight drain angle away from the foundation. This was used to help determine which way the graining stripes should go and the overall pattern. You can run water on the concrete and watch the flow pattern to decide how to use that to your advantage. If you do this immediately before staining, you may have to squeegee off the excess water. The final look is a sheer stain color as opposed to a painted look. Any imperfections or major stains on the concrete might show through. These things can be worked into the overall design, if needed.
I live in North Texas and did this in the early summer. Frank was such a great help in telling me the best time of day to apply the stain, neutralizer, and sealer. He also provided valuable information such as how long to leave the stain on before neutralizing and scrubbing off the excess. I stored the unused stain in the original container. One of the sprayers was rinsed out and used for the sealer. Then that sprayer was discarded upon completion of sealer application. I purchased the spike shoe covers as well.
Even though one section at a time was done, I still found myself having to step on a few spots where the stain was already applied. This was done to position myself to continue the pattern, making sure to walk on the applied stain as little as possible. or wear acid stain resistant shoes.
I was going for a marble-granite look, and got it. Many thanks to the several conversations with your technician, Frank. I wanted you to see the results.”
