Biscuit mix for UFH - admixture to speed drying?

[dentster]

I'm hoping to install a wet underfloor system between joists.

Going by the book, the drying time, is about a month for a 25mm biscuit screed.

It makes sense, but I wonder if I could blend in a small amount of accelerant admixture to speed the drying time.

Has anyone tried it? Or got an opinion?

If you mean drying, not hardening (which is not the same thing) then, no.

Yeah I did mean drying. A month is quite a long time to wait.
