me again.plaster board & bathrooms

[kickinside]

Hi all,

well i WAS hot on the trail of dot and dab plasterboard to the walls and tile away having cleaned the walls back to bare brick...

I have now been advised on no account to use plasterboard anywhere in a bathroom - that i should be using waterproof plasterboard at the least, preferably aquaboard -problem is as far as i can see they cant be dot & dabbed so that means stud work....and for 10mm poc tiles thats goign to mean 2"*2" (walls area bit out as well..)

The problem with this is that if i put stud work in all the baths/showers etc wont fit!

OOPS....

What say you guys to this sage advice ( the shower is a sealed 'shower cabin' so not in contact with the walls, bath will be bath only (no shower)

No one was mentioning this on her so i guess it may be BS im being told?

never dot and dab any boards just asking for trouble i can across a new build job that was dot and dabed boards they had to change shower tray took screen off tiles and boards fell off wall

oh dear, seems I may have got it wrong about MR boards and dot and dabbing them! (altho' it's perfectly ok with normal boards). I'll give British gypsum a ring today to clarify the situation😳

we dot and dab walls all the time and never had a problem, in the case you mention something is not right, whether the tiles exeed the 32kg per m2 limit, not used correct adhesive for dot and dab,whatever happened i have never heard of that before

phoned British Gypsum today (08705 465123 option 4!), absoutely no problem dot and dabbing MR boards, excellent material to tile onto.The adviser said the only cautionary note was to leave d&dabbed boards 7 days to fully cure before tiling (as I guess the added weight could possibly de-bond the dry wall adhesive from its substrate)

Doug, thank you very much for taking the time!

7 days is a bit of a pain though i was hoping to board and tile this weekend....wonder if thats MR specific - as others have said a matter of hours normally if you use adhesive for 'normal' board...i guess they may just be covering themselves good and proper as well.....

anyway many many thanks for taking the time!

You could also screw & plug the plasterboards, along with dot & dab fixing. I had to do this on a Pine end wall last year, when boarding the stairway/pine end to stop boards slipping. This was part of loft conversion I was working on.

Is that seven days just for the MR boards Doug

 

[doug boardley]

you got me there Whitebeam:lol: I was that pleased with myself in a smug little way that I forgot to ask on the normal ones I assumed that maybe the moisture resistance ran right through the board and therefore the curing time for dry wall was slower, but now I'm not so sure! I feel another phone call coming on :lol::lol:

I do know BG say the MR boards have to be pva'd before skimming:smilewinkgrin:
