What DPM should i recommend?

i have a mate who is laying dry-back Luvanto, in a new build house, so no need for a levelling screen. He just needs to damp proof the concrete floor. Does anyone have anything to recommend which can be stuck directly to?

 

If it's a new built it should have a dpm, or it is that it's so recent the floor is reading more than 75% and you need a suppressant ?

 

yep it`s got a DPM below the subfloor - but the actual subfloor (contrete) is still fairly damp??

 

Even though fitting dry back i would still screed it as the floor needs to be as flat/smooth as possible. Ideally screed/dpm/screed. Which DPM depends on the Relative Humidity readings of the concrete.

 

I thought dry back was stick fit system?? Looselay is the no glue/tacki one isn't it, if new build is 1kturbo it then smooth over top as the slabs are generally speaking still wet when house is sold usually I've found between 75-85%

 

yes, dry back is just standard stick down stuff!! great just googled it and it`s kind of stuff i was hoping for!!!
can he stick it straight on top of this??

 

Still needs to be levelled.

 

No will need to smooth the floor off and build up any low points, I'm assuming your diy by the questions asked, why not get an actual floor layer in to do te work properly? Abit of laminate is one thing for diy but once you are talking lvt it goes beyond a diy job and into the realms of costly mistakes, if for example you don't put the dpm down correctly you may as well not of bothered then 6 months down the line you've wasted x amount of money.

I'd recommend getting a pro in to do it right first time, just make sure to get references pics of work or direct recommendations.

 

thanks chaps for your help. as you can see i don`t have a clue on screeding & Sub floor!! have a good weekend!!
