Hi experts!
I have some questions about the best way to tackle tiling/painting an area where I have put up some Gyproc Moisture Resistant plasterboard.
A rough visual guide follows:
I have 2 walls with the MRPB and one breezeblock wall which is plastered, and am going to install a bath with a power-shower unit mounted above it.
There is a small area on one of the boards where I would like to paint it rather than tile it, but the rest of the area will be tiled.
Despite carefully searching for hours as well as reading the British Gypsum White Book I haven't found definitive answers to the following questions:
--------
1. The white book suggests that I should be able to tile straight onto the plasterboard as long a waterproof grout and sealant is used.
However I have seen numerous places where it is suggested that something along the lines of BAL WP1 should be applied first.
What is the general thinking on this? Is it better safe than sorry, or a bit over the top for this setup?
--------
2. I used straight-edged board rather than tapered as this was what was suggested for use when tiling in the White Book, which also says that to joint the board - fill the gap with sealant.
Does that sound right to you, or should I use some tape? How would I smooth the surface out though given it is not tapered?
--------
3. For the small painted area would I be correct in believing that I could use the Gyproc plasterboard Primer/Sealant and then paint straight onto it?
It looks like this will put me back around £40 though, which seems a bit daft for such a small area - maybe best to extend the tiling all the way round?
--------
4. What should I put on the areas of the plasterboard hidden by the bath? Do I need to protect it with something (presumably the BAL WP1 stuff).
--------
Hopefully that is clear, and many many thanks in advance for any help!
Cheers!
