How to prep shower wall for waterproofing

Hello,

I need to waterproof my shower. I have removed the tiles but being double brick I couldn’t just cut out the plasterboard and start again so the wall still has some tile remnants. Wondering what I do from here. Can I get screed applied over this to smooth out wall to then paint on the membrane or do I need to get every last remnant of tile off first? These tiles have been hard work to remove even with a hammer drill. I will let the wall dry out completely before doing anything. Thanks

Re: How to prep shower wall for waterproofing

Hi @crisis,

 

I'd suggest that you'd likely need to consider sheeting the wall with Villaboard to get a surface suitable for waterproofing and tiling. Are you planning on waterproofing and tiling yourself? If not, I'd recommend you speak with professionals in those trades to understand their requirements before they complete the work.

 

Note that the waterproofing needs to be done around the bath and on the flat tiled surface on the left. I would think that the tub really needs to come out to waterproof and tile the walls.

 

Please let me know if you have any questions.

 

Mitchell
