carlyai Posted May 24, 2023 Share Posted May 24, 2023 Yesterday 3 tiles popped up on my swimming pool. Extreme heat for the last 2 weeks and maybe gap between the tiles too small, but these 3 tiles are the only ones that have pooped and all the others have the same gap between them. I was thinking I would clean them up and re-glue them into place. I would like a recommendation on thin set adhesive to use. Something like just a smear of adhesive on the tile and concrete base.

Don Chance Posted May 24, 2023 Share Posted May 24, 2023 It's because the concrete subfloor underneath is wet. You need an underlayment. https://www.bobvila.com/articles/tile-underlayment/ 1 1 Link to comment Share on other sites More sharing options...
Skipalongcassidy Posted May 24, 2023 Share Posted May 24, 2023 The underlayment is fine... the thin set used originally was more than likely the cheapest possible and not really for wet installations... just find a tube of acrylic adhesive and you will be good to go... do not clean up surfaces... just dust and glue 1 1 Link to comment Share on other sites More sharing options...
Popular Post Muhendis Posted May 24, 2023 Popular Post Share Posted May 24, 2023 I had a similar problem with some balcony tiles a few years ago. I ground down the edges a bit to make sure the expansion problem was no more and used "No Nails" construction adhesive. Never had any problems since. Village builders are notorious for not knowing much about laying tiles with the correct spacing. 3 Link to comment Share on other sites More sharing options...

Muhendis Posted May 25, 2023 Share Posted May 25, 2023 Why are people arguing about underlayings, whatever that is, when the OP is about glue to stick a tile. 1 Link to comment Share on other sites More sharing options...

Purchased the 'nails' and about to do it today. Also ordered the SS316 bolts etc from Abpron Bangkok link given. Nice people. One wonders why pool shops sell pool ladders with no SS316 bolts. Thanks again. 1 Link to comment Share on other sites More sharing options...
Gsxrnz Posted May 25, 2023 Share Posted May 25, 2023 Had to force the bloke laying my tiles to use 3mm spacers, and leave a 5mm gap against the wall to be siliconed. He thought I was bonkers. 1 Link to comment Share on other sites More sharing options...

Try citing some supporting information... even your hero Bob Villa lays tiles directly over a properly poured concrete substrate... cement board is not required for outdoor Installation.
