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

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".

Using a 10mm square notch and back skimming, you will get around 5 m2 per 20kg bag.

Would I be better off using a U-shaped notch trowel?

I'm actually not a big fan of the u shape trowels, I've had one in the van for about 2 years now, hardly used it.

I laid 80m2 onto a Gyvlon screed & used 10 bags of AnhyFix, that was a 10mm trowel & tiles back buttered, it goes a long way,
The screed was really flat though.
