Frequently Asked Questions About Acid Stain

I purchased acid stain for concrete and the liquid looks different in the bottle than what I want my floor to look like. I purchased “English Red acid stain” and it is a pale green color in the bottle. Is this right?

Expert Answer: Great Question. Acid stains are a reactive product, meaning they react with the concrete. Our “English Red acid stain” has a greenish color in the bottle, but when applied to concrete that is free of sealers and paints, it will react with the floor and turn a brownish shade of red. The important thing to remember with acid stains is that they take on a mind of their own with your concrete and form all kinds of neat variations. Have fun!
