All edges of all sheets of drywall must land on a solid surface such as a stud. A hanging drywall edge may work in the short-term, but in the long-term it can result in cracks and other serious wall issues. Sometimes, the drywall does not horizontally reach a stud.

What should I put between drywall and concrete?

The solution is covering concrete with a vapor barrier, which acts like a resistant cell membrane instead. With a shield in place, the drywall is safe. Typically, a stud wall is then installed against the concrete, but furring strips are quick, easy and take up less space.

Can you pour concrete up against drywall?

You can put drywall over concrete, but it is important to be mindful of the process. Drywall should never be installed directly to a concrete slab, and should be installed over a barrier wall to prevent any type of moisture transfer, which could create mold and damage the drywall.

How much space should be between subfloor and wall?

There should be a 1/8-inch expansion gap between the edges of the sheets. Use an 8d nail to help you gauge this gap. In addition, leave a 1/4-inch expansion gap between the subfloor and the wall plates.

Do you hang drywall vertically or horizontally?

Is it better to screw or nail drywall?

While nails tend to be more flexible and hold up better against shear pressure—or lateral force—screws have much better grip and tensile strength, which ultimately keeps drywall from pulling away from the studs. When it comes to holding power, screws simply can't be beaten.

Should you glue and screw drywall?

A best practice is to nail or screw the edges of the board, but only use screws in the field. Using adhesive for drywall reduces the need for screws in the field or middle of the board but some are still needed.
