    UK Primer G on no more ply - dilution?

    I have the old stock no more ply down unprimed. (Their new stock comes pre-primed). Mapei suggested using Primer G before tiling with keraflex maxi s1. They did not recommend using SBR for some reason. Why might that be? What is the correct dilution of primer G to use on no more ply? The...

    Hi I’m a total beginner. I had a builder fit some laminate in dining room and while he did that he noticed we had the tiles for the hallway. Long story short he did the tiling but after few months we had grout coming up and tiles coming loose. Then discovered he hadn’t put anything over the top...

    'No More Ply' on old floorboards...

    Hi, I bought 6mm No More Ply for my bathroom floor before I tile. As you can see the floorboards are not perfect, and there is a piece of ply patching in one section. It all feels quite solid to me, but not perfectly flat everywhere as the boards are old. My worry is that when I put down the...

    Priming and laying No more ply

    Of the new NMP boards, which side comes already primed? The smooth side or the rougher side? Is it necessary to prime the side facing down before using the mega strength adhesive? I expect the megastrength would bond better to a porous surface so I think better to fit the non primed surface...

    Hi, I'm installing aluminum spreader plate under floor heating between joists (1930s house), and I'm thinking of using 22mm No More Ply over the joists, then tiles. What do you think about this setup? Is that better than ply plus a thinner backer board? Will I still get enough heat transfer...

    No More Ply for laying 600x300 porcelain

    Hello, I am planing on using no more ply over my existing 18mm flooring to lay 600x300 porcelain tiles. Would there be any benefit in laying 2 layers of the 6mm no more ply to create 12mm covering. Will this make the floor stronger or is the 6mm enough. The joist are 8x2 at 16inch...

    Apologies this is so long winded, but hopefully you're an understanding bunch & you'll stick with the novel and provide a straight opinion on this. I'm a competent DIY'er (ex-spark), but it's a while since I've done any DIY tiling at home. I'm now re-doing the kitchen floor/walls in a 1960’s...
