Tilling over plywood in a shower

Anonymous user 09/03/2024 - 2.56 PM

Hi there guys I am a tiler myself and to be honest very rare Tilling on plywood walls actually just a few times in small areas like kitchens but never a shower. The problem is that the tiles needs to be replaced as the old ones are popping out and the guy said that there was some tanking done and he wants this time the job done proper. Is a looft conversation exterior wall acutually both shower walls in a corner of the room and he said that the builders used some exterior panels outside than some insulation and inside plywood. I told him that we need to identify why the tiles are coming off and I know that plywood is not suitable for wall tilling especially shower. In the same time I said I will search the best way to fix the problem in the shower ( the odd thing is that only in the shower are coming off ). I mean not that odd as the temperature and moist and condensation is there and probably the thin wall temperature difference popped out the tiles. What do you suggest ? Acording that I will have to take out the actual popping tiles and replace just the tiles in the shower but finish flush with the ones left and right corner I was thinking about thin Hardy board and waterproof ( but that will push me out to much and I'll get in trouble finishing flush with the other tiles around and the taps of the shower) Or a schluter waterproofing membrane and kit and tile over Definitely using some great Keraquick adhesive for this job I am open to suggestions from professionals The job wasn't done by me ...

Are you a tradesperson and able to answer this question?

My guess, is that the outfit that installed the tiles over the ply originally, probably did not give it a good coat of tile primer. In which case, the timber drew excessive proportions of moisture out from the adhesive mix, first time around. Bal makes a good primer which will give the tiles better substrate adhesion - once dry. Use a flexible tile adhesive leaving clear spaces between the tile, and be extra thorough when applying grout; watching out for tiny air bubbles, make sure all gaps are sufficiently grouted, take your time. The costs of these materials can be pricey but essential, given the situation. Your client is unlikely to want you to cut corners a second time around the job afterall is remedial, good luck with it.

As before ...SBR prime ( diluted) and use a good flexi s1/s2 adhesive plus flexi grout Make sure that previous installers have put silicon behind wall profiles!! GW.
