Good Water resistant thick bed floor adhesive

[Sam2494]

Hi,

Currently in the middle of renovating an old property, dug up old quarry's and self levelled! Still out by 10/15mm in spots so looking for a waterproof thick bed adhesive. Needs to be water resistant due to do DPM, have used ardex NA for Self levelling as moisture resistant.

Anyone have any recommendations?

Cheers

All cement based tile adhesive is water-resistant not water proof. For thick bed I use BAL PTB or Weber Thick Bed, depending on where the job is.

Just because an adhesive is water resistant it will not protect from rising damp. A suitable DPM should have been fitted first.

Well after speaking direct with Ardex & Mapei both said that because we were tiling the subfloor a DPM is not necessarily needed, as long as moisture resistant self levelling is used! The floor will breathe through grout joints.

Sorry I wasn't asking that the adhesive to be waterproof from damp or to create a waterproof barrier I meant the adhesive needs to be water resistant so t won't break down when in contact with the moisture, I know most adhesives out the bag are unaffected by water

It's a fundamental requirement in habitable buildings to have a suitable damp proof membrane to prevent moisture entering the building from the ground. Ground moisture may also contain mineral ground salts these can potentially cause adhesive failure. It's your call of course.

This is why your floor was tiled with a quarry tile.... It's a natural tile with no glaze and allows the floor to breath.
What tiles were you thinking of putting down?

Not the case with lime screeds

Tilemaster standard setaflex white is breathable as is tilemaster pro flow 2 part leveller.
