How big of a gap can be filled with drywall mud?

Setting-type compound (the bagged kind you mix vs. the drying-type you buy premixed in a bucket) will easily fill a 1/2″ gap without cracking. Make sure you load up the gap well before applying your tape, then finish it as you would any other joint.

Is it better to install drywall vertically or horizontally?

On commercial jobs, fire codes often require seams to fall on the entire length of the framing, so the drywall must be hung vertically.

Why are my drywall seams cracking?

Cracks form due to stress placed on the seams. These cracks tend to occur around high-stress areas like windows, door frames, and corners. This stress can come from many sources. Temperature fluctuations can cause the drywall to expand and contract creating stress that cracks the seams.

Will drywall seams crack in cold weather?

“Every unheated drywalled cottage I’ve ever been in always cracks after winter,” says Jeff Graham, a contractor in Little Britain, Ont. During winter, the cottage frame expands and contracts; drywall, attached to it, doesn’t have much give, and can fracture. (Wood, on the other hand, deals better with winter movement.)

Are hairline cracks in walls normal?

Problematic wall cracks will typically start at windows, doorways or house corners. Generally, smaller hairline cracks are not cause for concern. These are usually the result of seasonal expansion and contraction of clay soils beneath your house over time, and can be easily patched and re-painted.

Can I just paint over hairline cracks?

For deeper hairline cracks, you may want to use a filler to fill up the cracks before applying a new layer of paint in the affected area. However, if an extensive area has been affected, you will need to scrape off the paint and then sand the entire area to even out the edges before applying a fresh coat of paint.

Why do drywall cracks keep coming back?



One of the top reasons why drywall cracks are happening often is because your home is already settling. After your home is built, the materials used to frame the walls dry out over the next few years, causing them to move slightly and develop small cracks at tension points near windows and doors.

What do vertical cracks in the wall mean?

Vertical and horizontal cracks in drywall or plaster walls typically indicate drying and shrinkage, which is normal after construction. Jagged cracks, stair-step cracks and 45-degree angle cracks generally signify structural movement or settling issues that are occasionally serious but usually harmless.

What do horizontal cracks in drywall mean?

Horizontal cracks in drywall are often indicators of foundation problems. These cracks can be caused by poor soil below the foundation, water damage, and more. Horizontal cracks in concrete walls often indicate serious issues as well.

What’s worse vertical or horizontal cracks?

Horizontal cracks



They usually occur because of excessive outside pressure, such as shifting soil, water pressure, or other sheer forces to the foundation. Horizontal cracks are much more dangerous than vertical cracks because they can quickly lead to total foundation failure.
