Acid-based chemical stains react with the minerals that make up a concrete slab. The end result is an etched surface in a range of earthy tones. Add a stamped design, and you can create the look of anything from natural stone to polished marble to stained wood.
These stains are semi-transparent, however, so be advised that they won’t cover any cracks or preexisting color. Proper surface preparation is key to any project, but it’s especially important when you’re using acid-based chemical stains.
