Drywall and moisture


Looking for some input here. What is your experience with having to finish drywall around gypcrete? Are office argues and argues you cant pour gypcrete until after walls are primed and not in the middle of finishing to avoid a bad finish. What do you guys do? Also is there an allowable moisture percentage of drywall that is acceptable to start finishing, even say in a job with water damage? Would anyone know where to find literature to back everything up?

Re: Drywall and moisture


United states gypsum produces tons of literature I carry a paperback version everywhere with me as far as the moisture question it all depends on level of finish. My opinion I wouldn't even look at a wall with water damage for fire tap until it dry and firm to the framing at beveled edge and all but joints unless the moisture was 3-5 inches above concrete.

My experience with Gypcrete is that it was used in multi family construction for sound deadening. It was always placed and dry prior to drywall installation.

Re: Drywall and moisture


We do lots of multi families, apartments and hotels. We've only done one where they actually did it ahead of drywall. Typically they do it after so we can hang, finisher texture and paint with it having to cover it. But schedules usually don't allow for enough time for us to get it all done in time and when they pour it there is a lot of moisture released in the air. We are currently on a project with 12 multi families, 11, 15, and 20 units. We have 11 days till hang, finish prime and texture 1700 sheets in the 11 families, in the middle of summer with no dehues or anything, just open windows. So we already have more time with drying when it's hot and humid and then they rush us through hanging to pour gypcrete in the middle of the finishing process. There is evidence of this showing in some punch list items, blistered tape and bands that show. I was hoping to find some literature to back up my arguments with general contractors that we can only go so fast and need time for things to dry especially with out dehues or climate control. Anyone else have experiences like this?

I would never install gypcrete until after the drywall installation

Re: Drywall and moisture


We dont want to but thanks to fly by night general contractors who would rather do it fast and repair the **** out of it over and over rather than take the time up front to produce a quality product we have to. But is there anything literature out there to back up my arguments? Because apparently me arguing that drywall and moisture dont mix isn't a litigate argument.

Re: Drywall and moisture


Very true, I thought we were the only ones dealing with it. Do you have similar issues?
