Hey all,
I just found this app and its at the same time amazing and intimidating. You think you know so much but there is always another way or at least another idea.
Which leads me to my question.
I am contracted to repair two emergancy staircases in a 9 story building that where damaged by a frozen pipe exploding on the roof. The sheet rock is flaking of and was moist in some areas and has since dried. Do I need to replace the rock or can I scrape, tape and prime with maybe a killz type primer?

By the time you go around, find, dig out, scrape, patch, etc, you could have replaced it all taped textured like normal and it will turn out better.

How much you talking?

Hmm interesting, I haven't thought of it that way. I was thinking if replacing the areas that appear the worst on the surface. At what point do you replace the rock to prevent mold?

Mold can appear at anytime when there is no ventilation. I think you just got to dig into it and see how bad it is.

Sheetrock can get wet and be fine. How do you think you get it to curve for radius walls and ceilings? You hose it down till it is soaking wet. But if it stays wet with no ventilation then it can go bad and mold develop.

Mud on the other hand can get wet and sometimes it will turn to a powder on the wall. You can scrape the surface but it might not take another coat of mud or paint. So you need to scrape/sand the compound down to paper.

Yeah I have been thinking researching a lot about wet sheetrock. In that research I came across bending sheetrock. Thats where my questions started about how wet it could get before mold, thanks for mentioning ventilation.

Not so much the rock being wet as the water trapped behind it that will cause mold...

When bending rock the first layer is dried out before the second layer is applied.

And did you mean to say mud "can't" get wet? I could scrape it down to paper prime then tape.
I am trying to avoid cutting out to many areas its so many little areas I think my tapers can scrape and prime everything in a day or two and spen the next 3 days taping and polishing.
