Hi Guys,
I'm the not very proud owner of a 10 yr old timber frame building in Bath. Which is plagued by design and build issues and I have had to virtually re-build it, look at "Homes from Hell" next spring.
Anyway, I have an on-suite and a bathroom on the 1st floor which both leak like a sieve and have caused timber and plaster issues and so have never been used (apart from to realise that they were un-usable).
This experience has kinda soured me and as a consequence I am doing belt and braces (with a bit of string just in case) on evrything I do.
I am now doing these 2 areas, I have taken the wall tiles off, the walls were normal pbd skimmed and painted then tiled, no bond between paint and skim so the tiles came off whole, I have lifted the floor tiles,floor is 18mm T&G chipboard, bond between chipbd and tile was average and about half the tiles came up whole, the grout between tiles on the floor was cracked as you might expect.
The pbd is in the skip and the timber frame exposed, only slight mould damage evident, and the builders had put up a 1000 guage poly sheet between frame and pbd, the spread who did the pbd must have had issues getting his board to fit as he took his stanley to the plastic in several places, and the plumber did much the same, and then the electrician must have as well, so if it ever might have worked after the trades had been in it didn't stand a chance, the shower spigot wasn't secured and water just went from the back of the spigot past tile, past pbd, past plastic (no attempt to collar seal) and down to the floor and found its way through a big hole where some one had ****ed up and not made good, to the ceiling downstairs.
I am proposing :
Make good walls with a screwed on concrete board like 9mm "no more ply", or hydropanel, or aquapanel, or hardi. Make good the floor with 6mm "no more ply" or similar (screwed & glued). There will be a height diference at the floor threshold so I need to find a trim of appropriate height (schluter / gemmini/ others??).
The floor can then have a decoupling membrane (ditra / others) and the walls a waterproof membrane (kerdi / homelux / others) with corners and overlap strip and collar seal for pipe work, also need a seal for a separate 4" vent pipe.
Job can then be tiled.
questions:
Threshold trim strip, must be others on the market but I'm not finding them.?
Sealing collar for a big pipe?
What products (primer / adhesive / cement) are best to use for bonding membranes ( waterproof and decoupling) to backer board on wall and floor?
