We recently had a bathroom fitting in who said he used dot and dab to fix tiles to the wall and in the shower areas and also stated that any gaps behind tiles e.g. Mosaics would get filled in by grout so it would be fine. We can however hear what we think are some voids behind the large format tiles.
We have challenged him with info from tile association and what we know of British standards but he has now said (to counter our argument against dot and dab) he "back buttered" and this is recommended. He also stated "the skill of the installer is paramount".
We also challenged him and said that the shower area should have been waterproofed. He said it was unnecessary and now is saying water resistant adhesive and grout is enough. We don't believe this is the case according to tile association but don't know re British standards. Also is a domestic shower classed as a "wet area"?
He also said the British standards can't take into account "differing situations that may be encountered in different properties " but surely a standard house and bathroom installation shouldn't cause so many issues and should still be covered by what is stipulated in Brit standards ?
Lastly he has said there is no excess lippage as per bsi recommendations. Does anyone know the recommendations and how we can check them? We know there are some significant dips in the mosaic especially at the edges next to large format tiles...
Any advice greatly received. The tiler has accused us of picking out our own grout and has lied throughout our comms with him. It's heading towards full on dispute :-(
