Sheetrock or Greenboard?

[fotoflojoe]

Hi All,

I notice that most builds have their walls finished with sheetrock. Given that a garage has a high potential to be a wet area, would it be prudent to use greenboard, aka moisture resistant sheetrock? This is the stuff commonly used in bathrooms.

Or, like all things, does it depend on the garage's intended use?

Edit: Think i put this thread in the wrong category, probably better to be in General Discussion.

Thanks,
-Joe

I'd vote overkill unless you're washing your car inside (and then it's probably underkill)- the small amount of water vapor that results from driving a wet car in shouldn't cause too many (any?) problems.

use the green stuff AND tape with DuraBond - NOT pre mixed joint compound!

you'll be glad you took the extra step.

If you think that you want to spend the extra money to use green board, then go for it. Is it necessary??? I don't think so. I have had sheetrock in garages for 40 years, and have never had a problem. In damp areas, such as a bathroom, I would use an oil based paint to retard moisture from permeating the sheetrock. This was before the green board was available. I would have to consider the cost factor before making a final decision. If the difference were small, then I say that the risk vs. cost factor might be worth the small difference in money. If the cost factor is huge, then I would say that you can get along without it.

Green board really doesn't give you much more moisture resistance than standard drywall. I understand it had it's moisture resistance rating revoked earlier this year. If you use a semi-gloss latex paint, and put a couple of good coats of it on the walls, you shouldn't have any problems.

You would think a good paint would seal it up enough....

i used Beahr "1-Part Epoxy Acrylic Concrete & Garage Floor Paint" on the sheet rock in my garage LOL seemed to work well.

Just my opinion, but sheet rock belongs in living rooms............green board belongs in bathrooms..........something puncture resistant belongs in garages/shops.

something puncture resistant belongs in garages/shops.

i was going to use OSB board for the lower part, then sheetrock for the upper walls and roof.

I only used MR board around where I'd be detailing cars, where the drywall went almost all the way down to the floor, or where I could use the extra scrap without too much taping.

And in my opinion, along with that of most home builders is that drywall belongs in garages. It's nice to have a fire retardant wall surface. Plywood/OSB belongs in polebarns and heavy use shops. After all, this is the 21st century.

I used 5/8" fire rated gypsum board and used setting type (the stuff you mix) joint compound over the pre-mixed stuff. It is amazing how much more abuse resistant the 5/8" drywall is over the 1/2" stuff and the setting joint compound is not affected by moisture the way that the pre-mixed stuff is.

Due to the walls getting banged up in my attached garage, I have chosen to put 7/16" OSU on the walls of my detached garage. I'll get some pictures and post...they look good and will be very durable.

 

[PAToyota]

For those using OSB, recognize that it isn't fire resistant. For an attached garage this is likely an issue if it is the wall between the garage and living space and can also be a potential issue with certain codes that mandate a maximum percentage of non-fire resistant surface covering in a space.

We had a guy that wanted to use Azek beadboard as a finish due the PVC being easier to clean and no maintenance but the inspector would not allow it due to it being combustible.

I am really jazzed about the prospect of using magnesiacore. It's been discussed before, but I could only find one post by someone who had actually installed it. I ordered samples via my contractor and he is putting together an estimate.

In short, it looks like the ultimate garage/shop interior finish: fireproof, moistureproof, hard surfaced, good looking enough not to paint, quick to install. Downside is cost which I still don't have a handle on, but I surmise that it is high. I'm hoping that it is cheaper than taped and painted sheetrock.

I did some searches lately and found discussions on other message boards. It turns out the stuff is very new, ie introduced in 2006.

I thought I saw that someone posted on here that the biggest issue is shipping - if you don't have a local supplier you basically have to pay freight to have it delivered or order a truckload of it or some such nonsense. If it gains in popularity and more places carry it that could be a good thing down the road.

I'm keeping my garage good old fashioned unfinished block. Of course I'll paint over it but no dry wall except for the bathroom.

What do you guys have running into the walls of your garage that 5/8" drywall isn't strong enough? I could see concerns about messing up the finish, but punctures?
