How big of a gap can you fill with drywall mud?
You can usually fill gaps less than 1/2 inch wide with joint compound while you are taping, but joint compound cracks when used to fill wider gaps.
The solution is to fill the gaps with patching compound or, if they are especially wide, with strips of drywall..
Do you drywall ceiling or walls first?
Hang drywall on the ceiling first, then the walls. Check the ceiling for bowed joists using a 4-ft. level. Irregularities less than 1/8 in.
Can you use 1/2 inch drywall ceiling?
Building codes do, have some requirements when it comes to the thickness of drywall panels. … 1/2-inch: Half-inch drywall panels are the standard thickness for interior walls, as well as ceilings. 5/8-inch: These panels are commonly used for ceilings, or for walls that require a prescribed fire-resistant rating.
How much space should be between sheets of drywall?
However, during installation, be religious about keeping that 1/8-inch space between sheets by using a guide. The blade of a drywall square is about 1/8-inch thick and does the trick.
Is it better to hang drywall vertical or horizontal?
Commercial: Hang the drywall vertically. … Hides uneven studs – Hanging horizontally also allows the drywall to flow over the framing so that bowed studs create less of a problem. If the drywall were hung vertically and a seam placed on a bowed out stud, the seam would be magnified because of the bump in the wall.
How many coats of mud go on drywall?
If your wall has distinct crevices, cracks, or textured areas, or if your brand of drywall mud isn’t offering enough coverage, you may have to do a couple of additional coats of compound. However, in general, you’ll need one coat to fill in the seams and three more coats after taping.
Why does my drywall mud keep cracking?
Drywall mud often cracks because it has dried too quickly or because the application was too thick. However, you don’t have to remove the mud and start over again. Instead, you can patch the cracked area once the mud has dried.
Should I sand between coats of drywall mud?
After the coat dries approximately 24 hours, sand the area. … When sanding use 150- 180 grit paper and always sand along the outside edge well, so that the transition between the compound and the CertainTeed drywall are smooth with no imperfections. Then sand the rest of the joint lightly in order to make smooth.
Should drywall be butted tight?
When you have flat seams that meet that aren’t tapered, you want those tight too, but you can get by with a 1/8-inch gap. Large gaps present big problems when you go to tape the drywall. The screws and fasteners need to be recessed so they have enough of the joint compound covering them.
Is drywall supposed to touch the floor?
Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall. It also helps prevents moisture wicking if the floor floods.
Do drywall seams have to be on a stud?
Ideally you want to make sure that the drywall seams are centered on a stud frame in order to secure it adequately to the structure. In situations where drywall is not able to be mounted to studs or other structural members, failure in the joint is likely.
Is it OK to have gaps in drywall?
You can (and should) squeeze drywall mud into pretty small cracks. Leaving a big gap just isn’t a concern. Put a nice coat of mud under the joint tape, squeeze it into the joint, then put another coat over the top of the tape and feather it out.
Do you stagger drywall seams on walls?
Generally, yes, sheetrock should be staggered. Most drywall contractors recommend staggering sheetrock boards so that the joints in one row do not match up with the joints in the next row, which adds strength to the wall or ceiling and helps minimize cracks.
