I’ve just laid 30sqm of tumbled unfilled travertine. I filled the pits with grout and the customer is really pleased. I now need to seal. However, there is a slight grout haze which is really annoying me. When I wipe the tile it goes, but of course it comes back again. I have been doing the room in sections and at one point I had one third of the room with freshly laid tiles, one third that had been grouted and washed down with water (shiny look), and one third that I had done the previous day i.e. grouted, washed down & hazy. The customer saw all three stages of the project and is overjoyed with the hazy look! Will it be ok to seal the hazy look? Or will the sealer react with the haze? Cheers Sean
