Tiling to Bonding


Recommended Posts

Hi All new here,

Just a quick question hope someone can help.

We have an old cottage, and the walls are all over the place...!

Having hacked the bathroom back to brickwork, and applied a LOT of bonding (I should have rendered it out a little first)

Anyway having now straightened the walls out, question is this.

Can I Tile on to the Bonding coat or must I plaster....?

Hiya Paul

Welcome to the DIY forum mate :)

To answer your question, you can tile directly onto the bonding coat if you really want to, but, beware that if you ever want to change the tiles, you risk damaging the entire depth of the bonding coat, rather than just a few mm of a nice skim coat finish...

Plus, bonding coat will absorb the adhesive much faster than the plastered top-coat, so "could" potentially wreck the adhesive by drying it out too quickly, as its designed primarily for wet plaster to stick to it rather than thick adhesive...

If it were my place, I would plaster first, then tile, even if it was just a 5mm skim coat, then white wash it and tile away :)
