Waterproof adhesive / Tanking??

[Jane S]

Hi all,

I am hoping someone can offer me their advice?!

My husband and I are currently renovating our house and we are now at the stage where every wall and ceiling has been plastered (phew finally). Over the next few weeks we will be fitting and tiling our corner shower cubical (tiling floor to ceiling inside the shower cubical only) on newly plastered bathroom walls.

My question is, if we use waterproof adhesive to stick the tiles do we still need to tank the shower area with a shower waterproofing kit (Dunlop??) or will waterproof tile adhesive be sufficient on its own? We were going to just use waterproof adhesive but when I started to look up tips on tiling a few posts mentioned tanking. I cant work out whether I can use the shower waterproofing kit on walls that have been plastered?! Sorry if that sounds silly… I am a newbie at DIY.

Any advise you can offer would be much appreciated!

Thanks v much!

Jane

Hi Jane and welcome..

The adhesive will be water resistant and not water proof.. If you want a water tight installation then yes use a tanking paste or membrane..

PHG wetrooms on the left of the page do great prices on either Aqua defence or Mapei mapegum...

As above better tanking to be sure its water tight when using the tanking were gloves and full overalls it gets messy

last time i used it was a big shower room and i think i got more in my hair than i did on the walls :lol:

yup as the guys above say.... use mapei mapegum. Pant on a couple of coats.

you will need to prime the newly plastered walls that you will be tanking though.

use primer g also by mapei. Screwfix sell it for about 8 quid

What tiles are you fixing to the walls Jane..

Thank you so much for your replys. I think we will be wise to tank the shower before we tile.
Noted on wearing gloves and overalls.

The tiles are ceramic 30x40 tiles. We are also going to do a boarder of blue glass mosaic tiles.

Thanks again for everyones help. 🙂

Morning Jane, for tiles that big I would be using a powdered, cement based adhesive (I use it for everything anyway) and not a ready mixed tubbed adhesive as it isn't really suitable for tiles of that size.

Hi Brian
Is the powdered cement based adhesive easy to use bearing in mind that i have never tiled before. Also, why do you think this is more suitable for the larger tiles than ready mixed tubbed adhesive? Just so that i can explain it to hubby 🙂
Thanks
Jane
