The tiles will be laid in a new build property, its lterally been built a few months back.
Concrete floors must be full dry (1 day per mm thickness) before tiling but if it was built a few months ago, you should be OK.
The tiles are going to be floor tiles and they will be BNQ porcelin tiles, with a glazed finish. They look pretty big, 60x60cm.
They are big & the floor needs to be very flat, if not use an SLC first or the finished tiles will be all over the place &, at that size, it will notice. Use only cement powder adhesive for that size tile & you will need a large format trowel for the floors & a thick, solid bed trowel for the walls.
Still unsure if you’re doing the walls but if so, what thickness & weight are the tiles? What are the walls, plasterboard or render/skim? If either is plaster skimmed & the tiles are more than 8mm thick, the plaster won’t take the weight. You need either raw plasterboard (no good for wet areas unless tanked) or a suitable waterproof tile backer board if you want it to last.
I'll be tiling downstairs, on the newly concrete floor, laid a few months ago.
Do you know what type of screed is it, conventional sand/cement or Anhydrite? Anhydrite must be acrylic primed or you may get a reaction between the two.
Also tiling upstairs onto new flooring. The floor appears to be thick MDF. Its not got your standard floorboards.
It’s probably chipboard not MDF, is it green? Chip (even green moisture resistant) is probably the worst possible tile base you could get, it’s crap & if it’s MDF it’ll be even worse. You can overboard with minimum 12mm WBP ply but TBH your better off ripping it up & replacing with 18-25mm WBP to keep the door threshold reasonable; actual thickness you need depends on your joist size/pitch/span.
I've done a lot of tiling using ceremics and done some quartz tiles, all with excellent results, but i've never used porcelin before so was hoping for a few tips! I;ve heard they are hard to cut and even with a wet cutter, have a tendancy to chip a lot.
You will need a diamond wet cutter on that size tile; a decent budget one will do but I would not advise you attempt to cut them on a budget manual cutter.
The adhesive is likly to be Unibond procelin adhesive from BnQ.
I would definitely advise you pick another brand of tiling products; you need to use a quality trade adhesive/grout, own brand & DIY stuff is mostly crap & that one doesn’t have a particularly good reputation. BAL Ardex, Mapei etc but not the one sold in B&Q, it’s not trade Mapei.
Tiling isn’t rocket science but there are many things that can catch you out. With walls, you must consider tile weights, prep & materials & suspended timber floors really do need special consideration if they are to last any length of time. I would advise you read the Tiling Sticky & Forum Archive posts before doing any work or buying tiling materials, it could prevent you making disastrous & potentially expensive mistakes. As already said, it’s also important to use only quality trade tilling materials of the correct type for your tiles & tile base; cheapo own brand & DIY stuff is mostly crap.
Post back if you want more advice on anything.
