Quick one for you. Are there any drawbacks to using plywood instead of plasterboard to partition off a very small portion of kitchen? I'm looking to partition a small walk in cupboard.
I'm yet to try my hand at plastering, so I'm thinking it might be easier to use plywood ontop of the studwork, given the small size. The finished appearance shouldn't prove too much of a problem (I hope) as I've experience wet sanding and re-painting some old plywood pipe boxwork - which has came out nice, plus the wall would be partially obscured by a fridge, and the last of the kitchen units and tiles.
What do you folks think? Would the material be suitable, and are there any applicable regulations on fire resistance/safety that might apply? The width of the finished partition would be under 2 metres.
Don't shout at me if it sounds like a loony idea lol! :wink:
I Don't think you need to worry about fire regs for a walk in cupboard. Of course you can use plywood, but plasterboard is better for a professional finish. I understand you may be worried about plastering, but there is no need. Plasterboard can be painted on without any further finish. You can buy a special thin tape to cover the joints so the overall finish will look just like a fully plastered wall.
Painting plasterboard is just like painting wallpaper as the surface is basically, well, paper so no special treatment is necessary.
As for PVA, well that is a can of worms! We often PVA before tiling especially if the wall is exceptionally porous, and the instructions on the can recommend it for that use anyway, but there are many posts on here that say DON'T use PVA as the adhesive is then sticking to the PVA not the wall etc.
I think you should mainly use PVA to stabilise any powdery or loose plaster and tile before it sets completely.
