    Hoping someone can give me some advice!

    We've put down a layer of smoothing compound, which is all fine. We were then advised that F77 liquid DPM would be a good idea before glueing down our floor. I bought styccobond b95 wood adhesive as it can go over F77.

    I've just seen on the technical sheet that you're mean't to put your b95 onto the F77 within 24 hours of it having fully cured! We're definitely not going to be able to do this and the liquid DPM is already down.

    We really don't want to put another layer of self leveling compound down (£ and height of floor). Could we prime F77 before the adhesive?

    Yeah, prime it and then cover it with a 3mm coat of stopgap 300. Good to go

    Don't want to put down another layer of self levelling compound though. Asking if there is a way to glue directly onto the F77.
