Question:

Does sheetrock(plasterboard) for a ceiling normally sit on top of the sheet rock for the walls.?

I'm new at drywall installation. I was wondering which to sheetrock first. The ceiling or the walls. Does the ceiling then rest on the walls(sheetrock)?Thanks.

Answer:

always do the lids first. (ceiling)the wall board holds up the corner. And you get the harder part out of the way.

It's common practice to do the ceilings first. It's nice to have the sheetrock on the walls to hold up the ceiling but not absolutely necessary. Just be sure to put in enough screws and when screwing, try not to drive the screws too far so the paper tears. If the screws tear the paper, they're more inclined to show up in a few years.

No, it creates a joint. I would advise doing your walls first, then the ceiling. You can use a screw gun to attatch your sheetrock to the ceiling cross beams. But generally the ceiling does not 'sit' on the wall. After you lay your sheetrock to on wall and ceiling, use joint compound to fill in the seams in the corners and ceiling, and to cover the screws. apply a thin coat and use a damp sponge to remove excess to create a smooth serface. After the compound dries (allow to dry overnight if possible) if necessary use a fine grade sandpaper to smooth any roughness from the compound and paint surfaces. Another option is to use caulk for corners and to fill screw holes. Follow same procedure as above.

ceiling first so as to have a tight seam at the wall, it does not really hold it up per say but allows the installer not to have to cut the rock tight to the wall when installing the ceiling rock.....always cut ur ceiling rock 1/4 less then ur measurement to allow easier installation....if u will check my answers page i detail this in a earlier question...... lic. gen. contractor

Yes... do the ceilings first then the walls.. it is to make the joints seal better when you fill them in with the mud
