which plasterboard for bathroom tiling

[a4arif]

hi to all.
i have bathroom with two bare external brick walls (old plaster taken off)
and two partition internal walls (have taken old plaster and wood strips off, vertical wood still there).

i want to tile wall and floor with ceramic tiles.
instead of a shower i will be installing a p-shape bath with shower screen.

i am confused as to what board to use before tiling. as there is mixed opinion in forums.

i would like to dab and dot the bare brick walls, and use screws on the other two walls, what board can i use (green plasterboard or normal plasterboard or other)?

as for water proofing, what would be the best method for where the two walls are above the bath.

i know aquapanel and tile backerboard are best, but i dont have allot of room to play with on the walls. so need best solution start to finish.

any advice on boards, primers & Adhesives much appreciated.

many thanks.

Personally I would use standard plasterboard 12.5mm but would tank around the shower area

I'm with Whitebeam... BAL WP1 is easy to get hold of, around £40

 

[doug boardley]

same as Whitebeam from me plus durabase wp for tanking

i assume you are talking about the Waterproof Coating wp1 only, if so do i need to use the bal primer first?
or do i need the polyester matting which comes with the kit.
thanks.

The primer comes with the kit, it also comes with some with all the matting, for your job you only need the corner mating, not

Full easy instructions in the box

1. plasterboard
2. apply wp1
3. Silicon round bath (fill 3/4 bath with water)
4. Tile
5. Grout (leave the bottom grout line between bath and tile and internal wall corners)
6. Let grout dry
7. Silicon round bath again and internal wall corners (fill bath 3/4 full)
8. Leave it 24hrs
9, Have a bath / shower

it'll hold tiles in excess of 20kg m2, so ceramic tiles should be fine

I would hold off on the shower for a bit longer eg BAL recommend 2 weeks wait for microflex to fully set .................

Micro flex is cured in 24 hrs.....2 week wait time is a bs5385 recommendation. this gives time for adhesive etc to gain full structural strength.

In general, how long would you wait to use a newly tiled shower, Dave?
