Hi,

I am about to install a bathroom into an extension I had built 3 years ago.
The problem is that I want to tile all the walls but cracks have constantly appeared over time on two of the walls, the walls were built from Durox lite blocks then plastered directly onto. I think this is were my problems started.
My question is what would be the best method to tile onto these walls /
I have seen the products on the market that provide crack isolation for floors, but haven’t found one for wall. Is there one? Or is there a different or better method for tiling cracking walls?

Hello and welcome.......

Schluter do a crack bridging membrane called KERDI and it is also water proof....but before commencing i would contact schluter to see if it practical in your situation...

why not just sheet the walls with gypsum, dry bonding the shhets could save time and money. Although thats still an expense.

I allways recommend dry wall on the durox blocks and the thermolites, Whenever solid plastering onto the blocks cracks nearly allways appear at a later stage.

kerdi will do the trick will take up the movement and waterpoof the bathroom at the same time
