We are currently building an extension and have poured concrete in the new area. We are about to have under-floor heating installed and the builder is proposing pouring a screed on top of this. I've discussed this with builders, floor suppliers, potential fitters etc, I'm between language barriers, my lack of knowledge and the fact we are never in the same place - I'm a bit confused about the best approach.
We are going to fit a 10mm thick, herringbone (with non-bevelled edges), engineered oak floor. We want the wood floor to be glued down. I believe this means adding primer to the top concrete surface, then gluing each block down. The fact that the wood blocks are unbevelled means it is vital that the underlying floor is perfectly flat otherwise it will look/feel naff.
I sense that when pouring screeds you only get one chance, it would be a nightmare trying to make it less if you pour too much, or of the wrong type. Would be really grateful for adivce on the best way to proceed.
Is it just a case of laying the UFH, then pouring "screed"? If so, precisely what sort of screed? How thick? Anything to watch out for?
Or is it the case that we will want to pour screed, but then add some sort of "self leveling compound" to make it super flat? And if so, what sort of self leveling compound?
I've been reading about it tonight, and it seems that "screed" covers all sorts of things and there are considerations about thickness, whether it is bonded, risk of curling, etc.
Thanks.
