Waterproofing bricks
Lots of questions ahead. Sorry about this.
I am re-tiling a bathroom and shower cubicle and want to be 100% sure the shower walls will be waterproofed. The walls are brick and it's all on a slab.
I intend to tile the hob and walls.
When membrane is discussed in terms of showers and waterproofing is it a thick paint or a plastic sheet membrane? I have read on this forum that the membrane can be up to 1mm thick. Will tiles successfully adhere to this surface?
Villaboard cladding is just for non brick walls is it not. Am I OK just proofing the newly exposed brick render then re-tiling?
Many thanks all

Waterproof membrane over render is fine as long as the render is sound. Membranes generally consist of a heavy paint-like substance, reinforced with fibreglass matting.

Hi
Go to Bunnings / Mitre 10 and ask for water proofing. It comes in 2 parts - 1 - primer
2 - a blue thick plastic paint.
and a matting for the corners
I can not remember the name of it and it's not on the invoice? Dunlop I think.
you need to check the regulations on where and how much water proofing is needed. for your state.
I did the wall to wall corners 100mm wide to approx. 1800mm high. base to walls corners - up the wall 200mm and the whole floor. All of the hob.
1st - make sure all the walls etc are nice and level.
2nd - prime all of the walls / hob. The primer also helps with the tiles adhesion. leave over night to dry.
3rd - put a coat of waterproofing 100mm wide in the corners , wall to wall and wall to floor, whilst it's wet cut the matting to size (the matting is like stiff bandage)to height of wall etc - place it over the water proofing and smooth out so it flat and stuck in the waterproofing with no air bubbles. Tip fold it in 1/2 right up the middle place the fold into the corner and unfold, start smoothing from the middle of the matting and the wall - so from middle to edges. So now you have all the corners blue. Oh do one corner at a time.
4th - re coat all the matting and do the entire shower floor / hob - 1st coat. leave to dry over night.
5th - do 2nd coat on all areas previously done. leave over night to dry B4 you start tiling.
I hope it all make sense!!

I have seen a clear plastic sheet membrane before, although I don't know if I'd trust the joins as much as a liquid membrane applied with a minimum two coats.
