What SLC to use over UFL - TilersForums.com

Maybe I'm doing 7-8mm deep then, spoze by the time I've stuck the 6mm insulation board strips as guides, the glue and sticking it on the ufh mesh could raise the strips a mill or two, since I've been doing it this way I consistently get 1.5m per bag..

Andy your not far out at all with that measurement, you’re better looking at materials than looking for them in my book.

Nothing worse than being a bag or two short right when you need it

I always used to work to 2m per bag but these days I think 1.5 is probably more realistic, your better pouring more than trying to scrimp to the minimum.

Always have a bit more than you expect to use! Running out is such a pain, init!

I'm in the 1.7kg per mm per Sqm camp works for me .

People say 3mm over wires but it’s never really enough, 6 or 7 is about the min I find

I agree it doesn't run out if you do it to thin .

Wow. I've only ever just gone over the 4mm wires. The tail end of the cable is buried in the substrate so is under 4mm. I've never gone above 5mm on the SLC. Don't forget BAL level max is a 25k bag. However, I will on future calculations use more. Most of my work is much smaller areas so I'm not buying in bulk. Nice idea about sticking down insulation board as a guide.
