Hello
I am a DIYer and after a successful shower tile project set about tiling bathroom floor. Victorian terraced house, previous floor - exposed original floorboards. After research and consultation with a carpenter, I understood that the deflection wasn't bad and that I should screw down any loose-ish floorboards and overboard with 6mm No More Ply using the NPM mega strength adhesive. Having done this and having been pretty pleased with my efforts I asked a tiler (and paid for consultation services) round to give me his opinion. He said that my floor has too much deflection and that the grout and possibly the tiles will crack. He gave me a couple of suggestions - the most expensive being to start again and lay down 18mm ply. This could be tricky as I understand that even in the event of a nuclear war the NMP will probably still be sticking to the floorboards because of the strength of the adhesive. The other option he said was to get some expensive adhesive - bal single part fastflex I think it was - which has an elastic ingredient and get flexible grout that you can add an additive to that will make the grout very flexible.
This evening I have been wondering if it isnt possible to double up with overboarding with a layer of ply or another layer of NMP. I also did a test that I have read about which involves filling a glass of water and placing in centre of room and getting biggest person you know to jump about a bit. Well I fit that profile so I have done that and no water was spilt. I can see some deflection in the floor but I am not sure what to think now. I am not sure what is acceptable, what remedial actions to take..
Anyone got any thoughts on this? I dont want to do a cr*p job but I dont want to pull the house down!
