Plasterboard in shower

Best Answer

"Apply SCHLUTER KERDI WATERPROOFING MEMBRANE for walls, wonderful thing, it never let me down. Grout I propose the company Bal Micromax. It looks great, it works very well. Recommendable.
All the best

"Tiling straight on plasterboard is common with shower proof adhesive and shower proof grout"

"If the walls are straight you can tile directly to the plasterboard. No other preparation is required as long as the surface is dust-free. You could use a pre-sealer for the wall. It is similar to PVA. One of the best grouts is made by Mapei and have a wide range of colours."

"if you are using board glue, clean the walls first and paint them with pva. also paint pva in front of the tiles, it will increase the adhesion of the glue. If the bathroom is upstairs, I still prefer to use a waterproof mapei kit. as for the grout, it depends on the tiler he uses"

"Personally if it’s the actual shower enclosure I would suggest that you use aqua- board. The plaster board (green) is only moisture resistant. Aqua-board is waterproof. I would use these in conjunction with Kerdi wall membrane before the final tile finish.
Another alternative is to use acrylic boards ???"

"Needs to be green water base plasterboard or cement board"

"YES, everything you saying is correct, and need to paint with waterproof manbrane"

"If I was doing your bathroom job , I would put the wedi board which is 100% waterproof, also on each corner I recommend to do the tanking ( with the special tanking tap and tanking material)."

"No the green boards are more than compatible to take a tile. Unless you want to add a water proofing kit for reassurance

"Hi.

Yes that is correct the green moisture boards are best for use in a shower area even better are the cement boards such as "HardieBacker" boards these are 100% waterproof. They are a bit more expensive but worth the extra in my view. You screw these to the wall as you would a plasterboard or apply with plasterboard adhesive if solid walls. Then you apply tape and a waterproof paste to all joints and Internals which you can buy with the boards it's called a "tanking" kit.
For grout, I would use ball microban easy to apply and polish off.

Hope all goes well regards
Steve"
