for construction guys?

Question

I'm going to school for architectural drafting right now and from what I understand right now on wall configuration, it goes:

plywood sheathing, studs, then insulation and vapor barrier over that, then drywall. Am I right? then what is put over the drywall for the finished wall and paint to be put on? We don't just paint sheetrock right?

thanks for support everyone , okay I read that some of you have said that you tape/texture over the shreetrock before you paint it. What is "tape/texture" and can you give me some information on it? thanks!

Answer 1

Interesting question, as most of the answers have said, you have the order of the materials right for most cases, but as one answer said (though it didn't explain why) in some hot climates where air conditioning is used extensively, the vapor barrier will be on the outside of the insulation.

In some high end installations, the gypsum board will be plastered, before painting, but in that case it is not usually called drywall, "blue board" is a term I have heard, I have seen the term "gypsum lath" in old books, but I don't know if that is common.

Answer 2

Yes, you paint right on the sheet rock paper - one side being made for the purpose.
"What is "tape/texture" and can you give me some information on it? thanks!"
When the sheet rock is nailed/screwed up, the edges are beveled. Fiberglass or paper tape is run down the edges overlapping both pieces and sheetrock mud is troweled on and smoothed into the tape, being roughly leveled to the sheets. After that dries, another layer is put on with a wide putty knife to a feather edge that blends across the edges, making (ideally) a perfectly flat surface. When that is dry it is painted with one or more coats.
If desired, texture can be added. Texturing can be done with sheet rock mud, being formed with a special purpose soggy long bristle brush making swirls or a trowel with toothed edges. Texture can also be shot in place, looking like small popcorn, with compressed air which may be left or flattened by knocking down. Texture must be painted with a spraygun normally.

Answer 3

Yes, you do paint the sheetrock.
As skytzo points out, tape is put over the joint between adjacent pieces of sheetrock, and joint compound is put over the tape and over the screws (or nails) to make the surface smooth.

So technically, the paint goes over the sheetrock and the joint compound. And the first coat of paint is primer (according to skytzo), so you paint the sheetrock with primer, and then paint the primer with a final coat.

Answer 4

Yes, we do! Prime coat and one or preferably two more coats to finish it. (The specs give the particulars.)

You have things in a funny order. The way to think of this is how you would build it, and that is also how to draw it. What comes first? The studs, right? And then? And then?

If you do this, you will draw things the right way. It is a classic error of young drafters to draw impossibilities, because they don't think about how the item is actually constructed. And the crazy thing about CAD is that the drawing might LOOK good, but that doesn't make it correct.

Answer 5

tape and joint compound. then primer a spot spackle and then paint or paper or vinyl wallcovering, and studs would go first. I'm sorry i just realized what you meant, and yes you had the order correct from outside to in i was thinking you meant the order in which they were put on and as far as the orange peel or knock down go they r done with joint compund and are just some options also i forgot to mention in case in matters if you are using wallcoverings you would also size the wals first

Answer 6

starting from the outside
plywood
vapor barrier
studs
insulation
drywall
compound on sheetrock (knock down or orange peel)
paint

Answer 7

Funny! 10!

Answer 8

If you want to build a much more energy efficient building, it would be (outside to inside):

Finished siding
Vapor barrier
SIP Panel
Drywall
Tape/Texture
Paint

Answer 9

Yep, we just paint the sheet-rock...
