Greyman 25,165 Posted August 13, 2020 Report Share Posted August 13, 2020 Feck me rusty you must love work, just dot and dab it with plasterboard, but if the tiles are stuck firm and straight I would recon it’s ok to go over them, have hacked off hundreds of bathrooms over the years and many of them had more than one layer of tiles on 1 Quote Link to post Share on other sites

foxdropper 17,092 Posted August 13, 2020 Report Share Posted August 13, 2020 DONT ply it mate .It will lift trust me .Latex the floor if needed but don’t ply it out .Pva the surface when it’s dry and tile . 5 1 Quote Link to post Share on other sites
foxdropper 17,092 Posted August 13, 2020 Report Share Posted August 13, 2020 Ply has a bad habit of taking on moisture and if the Dpm isn’t spot on you’ve got a problem .Weve just done a floor in a huge house near Bath that some tiler thought was ok to ply . Only advice mate no need for the racist imogee. Quote Link to post Share on other sites

Why would it lift never seen anybody say that before ? I had a new bathroom done there that was wooden floors. Tiler told me to stick down 12mm ply before he started and have it screwed down so it wouldn't budge. This was only 6 month ago Done my downstairs bathroom and kitchen myself. 12mm ply screwed to f**k onto the floor tiles in top. None have moved in 6 years Your tiler was cutting corners mate .Bathrooms need to be decked out with cement board over T and G boards . Take it or leave ,no sweat here .

eggy74 31 Posted August 13, 2020 Report Share Posted August 13, 2020 Tile backer is a couple of quid more than ply and designed for the job, can be screwed down or laid on an adhesive (cement board). Ive used ply before and never had an issue, but i have also replaced loads of bathrooms with tiles on ply that have popped of as soon as i start gunning them up, also sometimes the laminated ply sheet itself has come apart. as above check for door clearances and appliances will fit if going on top. 1 Quote Link to post Share on other sites

Atb j If I was doing the job, I'd take up the old ones first - if there's only 1 layer of tiles down already and they're all sound, you could go straight over the top. It'll make the job quicker and cleaner. As has already been said, you might need to sort the clearance on a door or 2. If you take them up, depending how rough you leave the floor, you might want to put down a leveling compound before tiling - if you go that route, use a tilers primer (not PVA) over the new surface before tiling.
