Help!: a few trade secrets please

[pete37a]

hi all

hope you dont mind me invading your forum,
i have a couple or three questions to ask all you professional tilers
here goes
1, ok we are talking newly skimmed plasterboard here, do i seal/bond if so what with?
2, am i right in thinking that for standard wall tiling the adhesive goes on the wall?
can it go on both wall and tile ? can it go just on the tile then fixed to wall .
3, is there any product on the market that is rapid set but also ready mixed (in a tub)

ok 4 then
4, if a ready mixed adheasive is uased and it is not rapid set how long should i wait before grouting and why.

thanks guys for any responses am not a tilier just a chap who has to sort a few tiles falling off the wall and leaking shower issues

What size tiles are you using 1st ?

Hi pete and welcome..

A tad more info please..?

[pete37a]

hi

size of tiles 300mmx 200mm x 6-7 mm
any other info let me know

[Sir Ramic]

right dont use ready mixed adhesive. You are much better getting fast setting white cement based adhesive. Mix it up in the amounts you require and grout within few hours usually. You can spread the wall or the tile as long as you get good full coverage.

And yes prime the wall 1st with SBR or Mapei G or similar...NOT PVA !

thanks this is good stuff,

why not pva? !
is there any ready mixed rapidset on the market ( im really looking for you to say no on this one )

[Sir Ramic]

ready mixed rapid set ... Not that i know of. For any ready mixed adhesive for walls you would need at least 24 hors drying time before grouting. I wouldnt entertain any ready mixed adhesive for floor at all .

PVA will break down when wet so dont use it for tiling.
