What is best to stain vertical walls and cinder blocks?

Ask a Pro

Q. -  Shotcrete vertical exterior retaining wall being installed and want to stain it. What product do you recommend? Also plan to stain a concrete cinder block wall and what works best with that?
Sincerely, Ed
Hello Ed,
 A. -  The artist grade concrete acid stain by Concrete Camouflage is best for both applications. Here's a couple points to remember. Stain is liquid like water and will tend to run easily, so you will spray it on lightly and follow behind with an applicator brush in a circular motion to ensure complete coverage and to remove any runs as you go. You can do additional coats to darken it up if you choose.
   Also, have your shotcrete guy to shoot you a couple sample board pieces to test the stain colors on later to ensure you like the color before doing the entire project, and keep a couple extra cinder blocks for that same purpose.
   The shotcrete and the cinder blocks will stain a different version of the color you are using. So it's important to do plenty of testing before hand. Then you can be sure that you are using the correct color or colors to compliment each other as well as their surroundings.
   A final thought is that while most standard grade concrete stains require you to seal them, the artist grade concrete stain by Concrete Camouflage does not require being sealed. Therefore, if you prefer the natural unsealed look with the vertical surfaces you can leave them unsealed.
