Hi been doing a large Indian stone patio over the last few days about seventy m2. Ended up running out of sand needing a couple of bags to lay last few slabs. As it was peeing down this morning I left the apprentice on job to clean off the slabs with a jet wash ready for pointing next week. When I come back I seen on a few slabs dark blue blotches of ink. The marker pen was suddenly missing too. Don't know what's gone on but the apprentice was keeping stumbled. Anyone know of my thing to shift the ink. Don't really want to change slabs. Coated in sbr and on a mortar bed a nightmare to get up. Thanks in advance
