Q. - Can I still stain my concrete even though it had a curing agent used? If so what do I need to do and how? Thanks
Hello Noel,
A. - Many times, certain curing agents will wear off on their own, so first you need to determine if the curing agent is still present. You can do this by pouring water on it to see if it readily soaks in which means it is likely not a problem, or if it beads up and/or just kinda sits there a while which usually means the curing agent still needs removed. Another method is to get down on the concrete and use a pocket knife to scrape the surface of the concrete, a curing agent will scrape off and be like a waxy substance.
If it does in fact still have the curing agent on it, you will need a citrus type stripper or our CSP stripper to remove the curing agent. If you do not get it all up with the stripping, then will need to lightly sand it using either a rented commercial floor sander or a floor buffing machine with the fine grit sanding disks. Then you can go forward with staining.
