If the stain remains after a few years of exposure to the sun. It is most likely that it has become permanent on the concrete. If that is the case there is no way you can remove the stain with cleaners or muriatic acid. The stain is not a surface stain the stain has deeply penetrated the concrete.
The only solution that we have discovered works very well is to color/seal the concrete surface.
The process is simple:
|1. Wash the concrete surface with SealGreen Color Stain Primer
2. After washing allow the concrete to dry for 12 hours
3. Apply SealGreen Tintable Sealer mixed with SealGreen Color, Color Chart watch video:
4. Allow to dry and apply some more if necessary.
5. The final look will be a mate finish and it will not change the surface of the concrete see pictures. SealGreen Photo Album look at Plain Concrete Stain section.
