When we built our home 2 1/2 years ago, we used the Quikrete cement stain on our floors. We read the instructions, and on my birthday, we spent the entire day scrubbing the bare concrete with the acid to prep it for the stain. It's tedius work, but we figured it was important to do it right.
The stain went on real easy and looked very impressive. We chose a dark brown color, but I forget the exact name of it for sure. After about a month, we noticed that it was starting to wear in high traffic areas and where the stools slid on it.
Today it looks terrible. It's an eye sore that we've decided to cover with tile in some areas and laminate flooring in others. I would never recomend this product to anybody.
I don't even think it's a real stain, but more of a type of paint for cement. it didn't penetrate the concrete and the areas that it's wore off look like the concrete in our shop. I think it will come off real easy if I ran a buffer over it, or any sort of wire wheel.
As for the acid etching stain, that might be different. I don't remember it having that name to it, so maybe you will have better luck then I did.
