Keraquick + 600x600 Porcelain + Andhydrite Screed - UFH DISASTER!

Cheers mate. I'll do that and will also mix Mapei Latex Plus with the adhesive as a precaution.

Nooooo, don't mix anything with it. Just the adhesive and water. Read the PDF and instructions before you start.

Sorry, I've just read the link and Adhyfix is an adhesive, not primer. D'oh! I'm with you now

Any primer in particular? Tilemaster Adhesives do a Primeplus and Flexmaster Primer.

Prime plus is the one I use, mixed 3 parts water to 1 part primer.

Brill. So this is the P.O.A...

1. Take up tiles
2. Sand, scrape and vacuum.
3. Prime floor with Prime Plus
4. Anhyfix with 10mm notched trowel and 1mm back butter
5. Leave for a month and slowly introduce heat.
6. Rock solid forever.

Hopefully!

Hmm.. Just read this:

"Anhyfix will be 100% compatible with anhydrite / calcium sulphate and can be applied directly without having to prime."

Saw your thread on this forum Bri about Anhyfix. I see its quite elasticated. Thats really good to hear

This definitely seems like the adhesive for the job. 40 m2 to lay so I'll get 9 bags.

Thank you for showing me this product. I just wish I'd know about it sooner. This Keraquick can go in the bin!

Leafcutter by any chance ?? I would take info from TileMaster websites and data sheets.

N&C Gypfix specify no need to prime unless surface is too absorbent....which it most probably will be .

What sort of m2 coverage can I expect from a 20kg bag of Anhyfix with a 8-10mm notched trowel and 1mm back butter? PDF states "20kg will cover approximately 5 – 6 metre2 at 3mm bed application".
