just the boy
I work for a plumber who does his own tiling. Current job porcelain tiles walls and floor with same tile. Customer wants the same colour grout on both. As I`ve been landed with the grouting I have a question. 2mm joints on walls and 3mm on floor. I`ve been given 2 different grey grouts to use but neither specificly states that they are suitable for walls, but one does a joint from 3mm the other from 4mm. As I take a bit of pride in my work I have been down this road before and found the floor grout was too gritty for a decent finish on walls. He tells me he has problems sourcing grey wall grout locally, and basically get on with it. Any comments.
