Levelling compound for particle board subfloor

[r3nov8or]

Yeap, that's my concern too, but there is only way to find out
The leveller see to be quite flexible - i've jumped on the leveller underflooring with all my might, trying to flex them when I land, and the leveller hasn't cracked.

I'll update this thread with how it goes. Currently acclimating the wood.

Put a nail into it, leaving the head proud the board thinkness, see what happens. Then simulating minor board movement, pull it out a fraction, see what happens...

Started the nail/gluedown. I'm doing full trowel glue spread + stapling every ~20cm. Both Makita 16ga brad nailer and Bostich flooring stapler happily hammer their metal both in just chipboard or chipboard+concrete leveller. Didn't have to adjust air pressure or anything when moving between just chipboard or chipboard+leveller. So far so good, no cracks observed (and glue should add extra layer of protection to hold leveller together if it ever cracks).
