   All 5/8" these days is Firecode "X".....I don't think you could get regular 5/8" even if you tried! What do you want to look out for..just rock and tape it and since it's your garage finish it nicely, prime and paint it so your Ferrari looks good in it!

   prime and paint

   I'll agree with Zano here, even just one coat of Kilz (or BIN, etc) will seem to "add" light to the garage. 

   If you have a Ferrari, then, go with a high gloss white to match the glossy concrete sealer.  Otherwise a semi-gloss to satin finish gives good wear (the matt finish of a flat can hold dirt & stains that don't get seen to right away--'cause it's only the garage . . . )

   Now is the best time to paint, too--the garage will never be as empty of "stuff" as it is right now (and that includes all the construction stuff now in there <g>)Occupational hazard of my occupation not being around (sorry Bubba)

   If you have to construct a fire wall, only type X is permitted.  While neither regular drywall nor type X are flammable, regular drywall crumbles when exposed to heat.  Type X is formulated differently so it can resist crumbling in a fire for quite some time.  It's that time you're buying when installing a fire wall.

   True fire code is based on time.  In most areas for garage purposes double 5/8 is an adaquate fire wall.

   I have never seen double rock required for a garage wall in a residence ... doesn't mean it can't happen though.  But all houses I have seen do require 5/8 on all the garaage walls and ceiling.  Now, if you're talking about a wall rated for a specific fire rating, double layer might be needed.

   Whenever you are asked if you can do a job, tell'em "Certainly, I can!"  Then get busy and find out how to do it.  T. Roosevelt

   If by Ferrari you mean 2000 Tacoma, then yes, I'll finish it real nice.

   I'm guessing I wasn't clear enough...I don't have much problem with the interior of the garage.  My aching shoulders have installed plenty of sheetrock.  What I was referring to was the gypsum sheathing that goes on the outside of the garage, beneath the housewrap and siding.  Do the seams need to be sealed?  How long can it sit outside uncovered.  Where can I get more info on this.  The City doesn't seem to be much help.

   Thanks.  As always.

   " What I was referring to was the gypsum sheathing that goes on the outside of the garage, beneath the housewrap and siding."

   That is not common construction.

   Where do you live? What building code do you use?

   Is this because it is a garage or is it required on all structures.

   What is the finsih siding?

   I believe that some areas with firestorm problems are now doing this. Also in areas where houses are very close together.

   Bill-

   All good questions.  I should have been more descriptive up front.  I'm in Portland.  The one on the west coast.  And don't get me started about all the building code issues and beaurocracy here...As a liberal, I've never lived in a city that tempts me to move to the dark side more than Portland...but that's an issue for another thread.

   The garage was built with the back wall (gable) very close to the property boundary (less than one foot).  Hence, the need for the firewall.  It seems excessive to me, as the garage is detached from my house and the nearest neighboring structure is 50 feet away.  But, hey, who are we to argue?  So, I bite my tongue and build on.  And get this - I'm using cement fiberboard for the siding - and they won't give in and say that meets the one hour rating they're calling for. 

   Maybe the reason I'm not seeing much info out there is because it's not typical construction.  I've looked on gyp board mfr's web sites and there just isn't much material out there on installation of the exterior stuff.  Is it more common in commercial construction?  Now I'm wondering how much trouble I'll have finding it.

   I'll see what I can glean from the inspector tomorrow.  If anything. 

   Cheers

   You must be talking about the reinforced gypsum sheathing board you typically see in commercial construction, going on over steel stud framing.  Every time I see a big box store under construction, I see it.  Yellow.  Goes on with screws, like inside gyprock.

   Are you obliged to cover it with something non-combustible?  Stucco would be a good choice.

   Bob-

   Yeah, I think it is that yellow stuff.  I wonder if my local building supply store will carry it.  And, no, I'm not talking the H. Depot.

   Stucco not an option.  Doesn't match the existing house.  It's a craftsman style design.

   This just seems awful excessive.  Especially considering I'm going to side it with cement fiberboard.  Sorta like the dry well they made me install to handle the rainwater on my 400 sf garage roof.

   Ugh.

   the dry well they made me install

   A "dry" well just doesn't seem very likely in Portland.  Maybe out east . . .

   A brand name for the exterior sheathing is DensGlass by GP (sometimes also called DensShield, but that's the tile backer product).Occupational hazard of my occupation not being around (sorry Bubba)
