I've been fitting some laminate flooring at a house and the homeowners were also having some tiling done by two "builders". Obviously interested, as soon as they went out I had a nose in the bathroom. Skimmed plasterboard and painted walls. Not ideal! Looked in one of the bedrooms and next to the Bal Green Star was some PVA:mad2: They came back and started unloading the tiles... 600x300 porcelain!! I had a word with the homeowner about making sure they didn't use the tubed adhesive and make sure it was a cement based one. I said, other wise you'll be getting a headache, literally!! So, would you say anything to the "Builders"/homeowner? Or not get involved?
