Acid stain for concrete interior floor
We are looking to stain our new concrete (interior) slab. We have all ready added a pigment to it, so we don’t want to cover it with something opaque. I love the look of the acid stains. I have a dozen or so 12X12″ blocks from the same pour of concrete to experiment with colors.
We had a friend apply a few colors of Soy based stain and it came out very opaque, basically covering the pigment we added to the concrete. On their web page they say the soy stain in semi-transparent, while the acid stains say they are translucent.
Does anyone have experience with one or both of these types of stains? What do you like or dislike about working with them? Can you thin the soy based stain so it is less opaque and still get good results?
I can’t find information about how toxic acid stain really is. Some say the acid stain isn’t really toxic, but the sealer is.
