Can I Stain Concrete that was Colored when it was poured?

Ask a Pro

   Q. -   Is this acid staining product compatible with tinted concrete. The poured cement didnt come out the color I wanted.

Hello Lisa,
   A. -  Yes it is compatible with concrete that was colored when it was poured. It works fine with Integral colors, which is color that is added into the concrete in the truck and mixed in before being poured, and also with Color Hardeners, which is a colored powder that is added after the concrete is poured and then worked into the concrete's surface.
   However, the concrete must be free of any and all curing agents, sealers, oils, grease, wax, and other contaminants. So, if it hasn't been sealed yet you can go right ahead staining it.
   Please note: The final color that the stained concrete will be, will be affected by the existing color of the concrete, so tests are certainly needed before staining the entire project to ensure that you like the color it's going to be.
I hope this helps
