I didn't think you were supposed to seal brick because then you'd lock in the salts. They'd come to the surface but get locked below the sealant, and be more white. This is contrary to what I've always been told.
Grout that’s been hardened on brick what should I clean it off with. I’ve tried using just water and it leaves a white spot where the grout is still at? I can’t use high pressure or it just blows the grout out.
I have the Same issue, I had a brick layer do a sloppy job on my House 12 months ago. now i need to figure out a way to fix it so it looks half decent.
@@jobber1984 Muriatic Acid should do the trick. If there are huge globs, you can use a wire brush. If you have globs as in the grout joints, try chipping them away. If you chip inside the grout joint, outwards, you risk messing up the joint, if you chip from the outside, you risk blowing out the edge of the brick. I usually go from the inside at minimal angle, and usually parallel with the joint. GL
cleaners that penetrate a dry wall can cause efflorescence. You pre-soak the wall to keep cleaners working on the surface and not going into the brick.
