Hey everyone,
I'm currently slate tiling my concrete front walkway and a small patio in the back. It's come out really nice, but it's been a long process. I applied a final sealant to the tiles before I grouted, and then followed the grout directions and misted the walkway with water twice over two days. This made the grout lighten up, but I wasn't concerned. It's rained several times since then and I haven't had two dry days in a row to apply the finish sealer to the grout. Looking at it now, the dark gray grout is light blue with a bubbly crust. It takes a bit of scrubbing to get the crust off, and I can't get all of it everywhere. It looks like its a lime deposit, or something like that, that's now leaving white (or very light blue) streaks following the flow of water from the grout lines across the tiles. I still figure I have to wait for at least two or three dry days in a row before I can apply the final coat of sealant, and I'd like to know if I should get on my hands and knees with a scrub brush to take this deposit material off before I do. Does anyone know?
