Can I acid stain my stamped concrete patio?

Ask a Pro

Q. -  This is a colored and stamped concrete patio that is a really ugly bright red, I would like to tone down the color to something with a more brown/black look.  Can I restain this, I have found that when I have used bleach on the patio the color would run, will this be a problem in restaining?
 
Hello Margaret, 
 
A. -  So long as the concrete is not sealed, and when you pour water on it - the water soaks into the concrete rather than just sitting there or beading up, then it should work out fine for you. The color bleeding is likely because the residual release agent that was used when it was stamped (which keeps the stamps from sticking to the concrete) is being washed off.
   Though you may want to do a test in an out of the way place first to be sure and to also ensure that you like the new color, before doing the entire project. I would suggest using the Concrete Stain Prep and then a good powerwashing for prep. Also, for a brown/black color I would suggest the Coffee artist grade acid stain by Concrete Camouflage.
 
I hope this helps.

What's the difference between Artist grade, Standard grade, and acrylics?

Ask a Pro
 
Q. - can u please tell me the difference between your artist and standard grades of acid stains? also what is the difference between your concrete stains and the acrylic / semi transparent / water base concrete stains that i have seen locally?
 
A. - The difference in our standard and artist grade concrete acid stains is that the Artist grade is a 1 coat acid stain as where the standard grade is a 2 coat acid stain. Therefore you will get double the coverage out of the artist grade. The standard grade is just that, the standard grade of acid stain that you'll find on the market today. The artist grade is pretty much the best that money can buy and actually ends up being a better value per square foot when all is said and done.
   Acrylic stains, semi transparent stains, water base stains, etc. or actually only disguised concrete paints that are using the name "concrete stain" to try and trick you into buying them. Make no mistake, acid stains are the only true concrete stains and are to concrete as wood stain is to wood.
