Sorry peeps, another pasterboard question
I will etiher attach plasterboard onto battens or if space allows, onto plywood/chipboard/mdf that would first go onto the battens and plasterbaord on
top.
Not sure which would be the best from to use - it is to make a partition around an airing cupboard housing hot water tank and pipework in a bathroom -
away from shower; requirement is strong but thin. The extra board to add a bit of strengh, may not be necessary as the parttion is 700 x 2450.
I am not a believe of the "no-nails" adhesive so would use screws into the p-board; but would I need to use penny washers to spread the
load? I will be tiling over the p-board so the tiling adhesive would need to be applied so as to cover the screw heads - sound like a good plan?
Or is there a better way?
Skimming - some mentioned from other post n this topic that that would be needed ... but if I apply tling adhesive, then tile, then will that not
achieve the same result?
Any other tips appreciated. (and yes, I will cut the board so the ends are over a batten.)

No need to use washers, just use plasterboard screws.
Have you considered a tile backing board rather than plasterboard? It is very strong and stable in wetter conditions and as the name suggests its for
tiling on! I used it in the shower area of my bathroom and was very pleased with the way it went on and the way it tiled.
Depends how wet it might get and how heavy your tiles are really.
If you use plasterboard then battens at 400mm centres will be fine.

plasterboard screws have a curved head that helps stop them pulling through. If its dry, just tile straight onto it.
Beware! Bourettes is binfectious.

This is the stuff birdii recommends Wickes
You will need the ceramic tipped screws to fix it.

Dont forget white side outside on the plasterboards, when using plasterboard screws tighten so the head is just flush below the surface dont rely
entirely on the torque setting on your drill driver what might be just right on one screw might bury another.

Backerboard (aquapanel) as advised has the advantage that it's strong. however it is also more expensive and blooming heavy (so whatever you
screw it to needs to be robust). Just build a stud partition box with noggins depending on the p/board thickness used, screw it in place with
plasterboard screws (as mentioned no need for washers), slap the tiles on top. Job's a good'un. the most tricky bit will be tiling the
edges if you've got an external edge  No need for skimming, you can tile straight onto p/board.
The main issue will be that p/board can flex. Tiles can't and most tile adhesives don't flex much. So you'ld want to make sure
it's firmely held in place. IE lots of noggins and I'd be tempted to use 12.5mm p/board not 9.5. As much as you're not a believer in
no-more-nails personally I'd screw+glue it Kind of like sikaflex + rivetting a chassis!

I think the plasterboard ideally needs sealing before tiling, just a brush coat of thinned PVA is needed other than that should be fine.

Hardi backer board is designed for just this purpose - nail, glue, screw to wooden battens then just slap the tiles on.

no need for backer boards etc behind a sink, they're for wet areas like showers.
most adhesives say they can go straight onto plasterboard but i usually seal it anyway but not with PVA, use a proper acrylic primer

as said no need to skim, it also alows you to put on heavier tiles as plasterboard can carry more weight than plaster.
unless your using small tiles i would use a cement based adhesive, i use this one most of the time
