Drywall question


yes it is but the seam on the edge of your casing looks like crap (i know, load it with caulk, right?) and very unprofessional...get a couple sheets of 5/8"s for that wall... shim the studs ...or plane down the window...there are always a couple options ...the easy way or the right way lol

But it's always nice when they happen to be one and the same!
and he said the window is vinyl, so no planing there....

Drywall question


I guess there are differences in the "moisture resistant" board in different areas. You call it "purple" it can also be "green" which is what I'm accustomed to and it does come in 5/8" (firecode actually). With proper ventilation in your bath and proper paint, there's no reason not to use regular 5/8" board. Water resistant board is just what it says, "resistant" to water/moisture. It is by no means water "proof" and probably not as good a product as the "paperless" drywall available if mold is your issue. I think a lot of people are going to extremes worrying about mold issues (which is the "new" asbestos) and overthinking a very simple system that has worked for many years. Regular drywall with the proper paint for "humid" areas and above all, PROPER VENTILATION. My house is 35 years old and has regular drywall in the bath areas and never a hint of mold on the walls (well, maybe the tile)....

Drywall question


well I did have some mold problems on the ceiling and walls before I gutted it. It would just wipe off with some cleaner.

I did not have an exhaust fan though, which I do have installed now, so that should help a lot with moisture control.

Maybe I will just go with regular drywall then. I already have regular drywall on the ceiling.

Drywall question


I agree. Shim the studs. Do you have a table saw. Will take no time at all. Why hang 5/8 on an entire wall just to come out to match a window frame? Shims ripped from a couple of 2bys will set this guy back $10?

Drywall question


i dont think you are supposed to put a vapor barrier under greenboard . it creates a double moisture barrier . might want to check on that.

i've never heard that before. Anybody ? and reason please.

shim out the studs as advised...fast ... and you won't have to play with
the trim for many hours to get it right.

good luck

PS
moisture resistant board is not a vapor barrier.. yes one does not want to make a "pocket"

Drywall question


If by chance you installed the "green board"... we ain't got no purple board round dez parts. You could install the trim and float some drywall compound 2 wide knifes wide to blend your problem away.

The best solution for you is based on what you feel confortable doing. Your the only one that knows. Lots of ways to skin this cat.

There are six ways to do anything. Out of those six...three are pretty good... the best solution is whatever the mechanic doing the work is the most comfortable with. They know their skill level and the tools they have to get it done.

----------------------

not trying to start anything but isnt that sort of an oxymoron .

moisture resistent board is not a vapor barrier but it resists moisture ? vapor is moisture . so yes it sounds like a vapor barrier to me.

ive hung sheetrock snce the early 80s and that was what the inspectors claimed . infact if you hung greenboard over a vapor barrier they would flag you but things mighy have changed by now havent kept up with current products, im not talking about tile backer etc.

Drywall question

I am puting up new drywall on the walls of my bathroom, and I am using moisture resistant drywall on the walls (purple board), but the window in my bathroom sticks out 5/8", but the moisture resistant drywall only comes in 1/2".
Ask for 5/8" Densarmor Plus Fire Guard Type X.

Quote:
I have insulation in the wall and a vapor barrier stapled over it.
IRC R702.4.3 Limitations. Water-resistant gypsum backing board shall not be used in the following locations:
1. Over a vapor retarder in a shower or bathtub compartment.
2. Where there will be direct exposure to water, or in areas subject to continuous high humidity.
