Jumpax help

I'm putting jumpax with a vapour barrier over a new concreate slab (full of lignite) does the floor still have to be below 75rh? I havent tested it yet but should imagine it will still be wet

 

You would be better off with a isolator sheet or something like Triton dpm underlay

Do you mean use the isolator instead of the vapour barrier or instead of the jumpax?

 

Instead of the vapour barrier. It’s a floater system so no need for latex and dpm that will put another day or two on the job

Floated
Plus you will have to grind that subfloor. Not a nice job

Check out Triton platon comfort. Cheaper than isolator and better dpm system.

Lignite, I’d be getting that up
