hi lads just wondered how long does it take to pick up ready for float and sponge on top of hp12,thanks
I have used it on concrete block and that took around an hour and half.unsure on hp12 it's great stuff though

Is HP12 the Parex equivalent of monogris?
If so it will hang for ages. Will take hours to pick up before you can float

Jesus, can anyone really answer this question?
At best it's a rough guess. There no exact science here. 1 mans hour can be another mans 3.
