attach the floor gypsum?

[mindz]

we have installed waterborne underfloor heating in the hall, and laid the heat plates but what should one use to glue the floor gypsum with? what do you use?

I used something called BoardFix when mounting drywall on particleboard. However, it was without underfloor heating, and I don't know if it works with it, but it might be worth checking out...

Do you have to glue? You can screw instead, if you have full control over the loops that is!!

 

[gadu^]

One should glue AND screw to hold down the gypsum board. When the glue has dried, you can/should(?) remove the screws so they don't pull upwards.
Read this in another thread here, search!

I used Ardex S48 when I glued the floor gyproc in the hallway. I did as gadu wrote, first adhesive and then screws, which I later removed when the adhesive had dried.

the best thing about ardex S48 is that no screwing is actually needed

How are your heating plates attached?

I laid floor gypsum in the hallway 15 sqm yesterday. I also have waterborne in plates underneath. My plates are just lightly stapled to the lattice underneath, so gluing the gypsum there seems pointless. I just screwed it in. Managed to avoid hitting the hose, but it's a bit nerve-wracking to screw. Carefully draw out where the hose goes beforehand.
