How to keep cracks in drywall from coming back?

How to keep cracks in drywall from coming back

The best way to keep cracks in drywall from coming back is a good installation. Make sure to use the right drywall and the right mud tape so that you can strengthen the seams accordingly to prevent cracks.

There are different levels of drywall mud. Some are more adhesive, which are great to use for the first coat. For the second and third coats, you can use a lower level mud.

Use the quick-setting hot mud or all-purpose drywall compound for the first coat. Then use lightweight mud for the finishing.

Another thing to notice is to use the right kind of tape. Drywall seams are normally covered with paper tape, which is stronger and prevents cracking a lot better than fiberglass tape.

Do not use the mesh tape if you are going to use the quick-setting hot mud.

You can mix glue-like drywall mud setting additives can into your mud to make it more malleable when dried. The glue-like additive prevents cracking or limits it when movement happens.

To prevent hairline cracks in areas where the corner bead meets the drywall, do not nail the corner bead into the framing. Then, use a mesh over mud legs of a metal or vinyl bead to reduce the amount of compound needed so you create a smooth transition.
