30mm gap to fill for tiling (photo) - Tile Advice

[Mattybaby19]

I had to move the toilet waste pipe over and am now left with a 30mm thick gap (see photos, just over 2 plasterboards thick).

The whole area is gona be tiled with 200x100mm ceramic metro tiles so not much weight really.

I dont want to bond it as it will take over 4 weeks to dry. I had a shallow chase filled in on the same (solid external wall) wall 4 weeks ago and its still not dry.

What would u do to fill the area so its ready for tiling?

Cheers all.

Build it up with a fast set bagged cement based adhesive.

Would dot dabbing 2 layers of plasterboard work well?

D&D 1 or 2 pieces of plasterboard.
it'll be dry before you've made a cup of tea

Or Ardex AM 100

Or double skin PB as above

Ardex A46, mix it up to a consistency a little thicker than bonding & slap it in, sets in around 30 minutes, doesnt slump. Excellent gear
