Hi all
I may have a potential issue with some work a builder has done / is doing in a new shower room and would like to understand what could possibly happen and how to rectify it at this stage.
So currently, the builder I'm using has put NoMorePly 10mm XPS tile backer board on stud walls. I discussed using these with the builder and picked them as they were a good choice for being waterproof.
However, the builder has not used the recommended NoMorePly products such as the recommended Tile Backing Board Screws + Washers or the recommended NoMorePly Mega Strength Tile Backer Board Adhesive or the recommended waterproof jointing tape such as the NoMorePly Waterproof Tape.
Instead they have just normal screws to fix the XPS Tile Backer Boards to the stud walls, along with THIS PRODUCT - Sticks Like Clear All Weather Adhesive to glue it down. However, they have not used the Sticks Like Clear Adhesive within every joint line, nor have they used any waterproof jointing tape whatsoever!
I noticed this after all the XPS tile backer boards were in place, but thought the waterproof jointing tape or sealant would be put all over the XPS tile backer boards wherever there were joints before the tiles were laid. Unfortunately I went to work and came back to find most of the tiles were fixed to the wall but no waterproof jointing tape or adhesive had been laid across any of the exposed joints.
I did question the builder about this and was told it wouldn't be a problem, that they do this all the time, and that the grout and the silicone would mean no water would ever get through.
However, after speaking with someone at Topps Tiles today they said the grout wouldn't prevent issues if the XPS tile backer boards haven't been waterproofed / joint sealed etc. The staff member I spoke to seemed quite nervous that the job wouldn't last!
Therefore my concern is that over time, or even immediately, moisture is going to penetrate the wall structure and I'm going to end up with mould, damp, failing tiles and ultimately the job needing to be re-done.
My questions at this stage therefore are?
1) How likely is it that my tiles and the walls behind etc are going to be ok?
2) Is there a particular grout & sealant I can use to prevent moisture / damp issues and also try and prevent ultimate failure of the tiles etc?
3) Do I re-question the builder and insist the job is started again?
4) Any other suggestions please?
thanks in advance, feeling quite stressed and frustrated with this as I don't want to be paying thousands of pounds for a job that isn't going to last or is going to cause other damage to my house.
