WILF 47,282 Posted August 13, 2020 Report Share Posted August 13, 2020 Most houses over here are built on a slab, the method looks to be very different from most UK houses lads. Jethro I’m guessing will be going onto solid concrete. @jetroI could be wrong mate, so it worth checking, but I think you need a special adhesive if you are tiling over existing tiles. 1 Quote Link to post Share on other sites
PLEDGEY 496 Posted August 13, 2020 Report Share Posted August 13, 2020 Used to refurb pubs and if the floor had tiles on it we would just go over the top. As long as what you're going on top of is sound there's no problem. If the door opens into the tiled room you'll have to trim the bottom off of the door, and you may have to add a transition strip. This goes in the door way and covers the 'transition' between your tiles and what ever is the other side of the door. https://www.google.com/search?q=carpet+to+tile+transition+strip&client=firefox-b-d&source=lnms&tbm=isch&sa=X&ved=2ahUKEwiS5Mfp_5jrAhVRQMAKHX4KBEAQ_AUoAnoECA0QBA&biw=1280&bih=618&dpr=3 1 Quote Link to post Share on other sites

It's a slab house wilf. Was looking at them this eveing, and it will be cheaper and easier in the long run to rip them up. Instead of shaving doors to close properly again and other problems.

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 The trouble with tiling over ply is after six and a half or seven years tops the ply delaminates and it costs an absolute fortune to put right.... 1 1 Quote Link to post Share on other sites
Waz 4,266 Posted August 13, 2020 Report Share Posted August 13, 2020 I tiled over existing tiles once for a client, scuffed up the glaze on the existing with a disc cutter and used a primer before retiling, all good. 1 Quote Link to post Share on other sites

Qbgrey 4,113 Posted August 14, 2020 Report Share Posted August 14, 2020 Never lay ply or any wood ontop of concrete,moisture trap,and if you use 18mm ply,then adhesive,then tile your going to be up about 30,40mm depending on tile.plying is fine on joists as you have that airgap underneath.ply should only ever sit ontop of insulation,called floating floors. 1 1 Quote Link to post Share on other sites
