So, I have a wall in bathroom. All its old plaster now removed. Wondering wether to dot & dab or batton it AND which plasterboard to use; moisture shield / vapourshield or straight forward normal plasterboard.

I'd prefer a moisture shield board but I've read that this must be battoned & not dot and dabbed, which puts me off. Wondered if anybody cud offer their advice on this?

if its not in a wet area you coud D & D with plasterboard

Do you mean moisture resistant board or one with a vapor check board with the foil on the back

hi, thanks mikethetile and whitebeam. its not that wet. one bath, no power shower etc. so normal plasterboard cud be.

I was going to use the moisture shield board. I then read the whickes website for gypsum based moisture shield board, but it advised not to d & d????? - only mechanical fix?? which board wud u rec' 4 d&d of this bathroom. and what's the difference?

I would use a standard board and prime if you wish with a sbr, the moisture board has very low suction.

I have standard boards in my shower, like yourself I do not have a power shower but used bal epoxy for the grout.

I would use a powdered adhesive and a good grout, mapei ultracolour is a good one

Thanks whitebeam. It turns out today infact that we are to be having the moisture shield. Not that pricey actually. But you mentioned that it has a low suction? how wud this affect my tiling then, is there anything i should be prepared for, am gonna be D&Ding them onto block work on friday....& i cant wait... oh and i have another wall thats skimmed and in good nick am currently using a bit of patching plaster and sanding to tile straight on top but wondered wether i could d&d plasterboard straight ontop of the skimmed surface but have read plasterboard should be dot and dabbed onto the brick or block work ideally...... whats ur oppinion on this one chap???

Standard board is dot and dabbed, I would fix the board with battons on the wall just so to follow wickes advise.

hello fellows. Just wondering i've now gone for regular plasterboard.... and cut it to size and ready to d&d on the wall. the substrate is breeze block, was going to PRIME the block work first? thats what av read in my college notes.

BUT WHICH PRIMER TO USE FOR THIS & WHATS THE OPEN TIME OF SUCH A PRIMER?

I don't prime before dot and dabbing plasterboard with adhesive, just damp the areas with water before fixing

that's sorted then. cheers. But which dry wall adhesive, normal whickes bonding compound?

That will be fine.

Any of the adhesive stick like the proverbiale to a blanket. Never had one that didnt do its job

cheers lads. thats the plan for tomo then. av also bin using patching plaster to bring a skimmed wall out slightly prior to sanding and tiling straight onto. how long shud this be left prior to tiling onto with ceramics? bin about 1 week now. that probably sounds like a real novice question

If its only the thickness of skim then it should be ok by now

Should be ok, did you use a pva/sbr before you put the patching plaster onto the new skimmed wall

well, in places Scottlley its about 12mm thick! Also av D&D the p boards up - lovely. enjoyed it. But should i use mesh tape for the p board joints together with an adhesive, and if so which mesh and adhesive?

Whitebeam
- the skimmed plaster was an old skim. And NO i didn't pva/sbr!!!!!!!!!!!! that gonna be an issue do u think?

Just check the patch dos'nt sound hollow
