Hi All
I laid 50sqm of indian stone (Fossil Mint) a couple of weeks ago and once i had completed it realised i wasn't as careful as i thought i'd been in regards to staining the indian stone with the mortar. However i'm lucky enough to have a plant and tool hire company so had a range of equipment to solve the problem and thought i'd share it with you.
I tried an industrial pressure washer which for the most part did no good. I then used an angle grinder with a crimped wire brush cup, this removed the stains perfectly but left a metallic residue on the surface which came off with the pressure washer. Please note i used a CRIMPED wire brush cup not a TWIST KNOT wire brush which is far more aggressive.
Must admit i breathed a sigh of relief cos the next step was to go nuclear and bring the sand blaster home!!!
Hope this helps someone
