Drywall can’t be hung without an appropriate compound to join all the pieces together. If not completed properly, you’ll end up with mud cracks that won’t go away. Let’s learn more about the process now.
Generally, drywall mudding is necessary to join your sheetrock pieces together and form a smooth wall. The first coat goes on the seams and fasteners to hide them. Unfortunately, cracking is possible, which is challenging to fix.
Reasons You Might Experience Drywall Mud Cracking
There are many reasons for the mud to crack once it’s dried. The main one is that the professional used the wrong drywall mud compound thickness.
However, it’s important to realize there are different types of drywall mud, each with its own drying requirements. For example:
- Premixed sheetrock compound uses evaporation to dry. This often results in shrinkage cracks forming during the process.
- Powdered drywall mud must be cured to dry. Therefore, there’s less of a chance of it cracking.
Likewise, some drywall mud types are used only in specific situations, such as for a top coat. It’s important to know which option you need.
Can You Prevent Cracked Mud?
It is possible to prevent drywall mud cracking. Applying it in a thinner coat will help. Plus, it’s important to follow the directions for the compound type you use.
Different drywall types have varying densities and drying times. You must take that into account when you apply the joint compound. A thick first coat might not dry properly, meaning you would have to scrape off that layer and start again.
Repairing Drywall After Cracking
Repairing drywall cracks is possible, though it’s not always easy. The first step is to determine if you should start the mudding process over again. This is often wise if the layers are too thick.
If you don’t have to start over, allow the compound to fully dry before doing anything else. You’ll likely need to sand the cracked mud to remove loose pieces. Professionals often use putty to cover the cracks.
However, the professional might also place a layer of drywall mud over the crack, tape it, and add another thin layer. They’ll let all that dry and sand it smooth.
Sometimes, it’s also possible to use crack filler products to fix the drywall seams. However, there are many types available, and it might be difficult for you to determine what you need. Ultimately, it’s wise to work with a professional. They’re knowledgeable about the tools and materials available and will make the right choice for your situation.
Final Thoughts on Drywall Mud Cracks
Mudding sheetrock is a necessary process, but it’s not as easy as you might think. Therefore, it’s best to hire a professional for the job. Even if it’s applied perfectly, the joint compound could still crack overtime. Experts know how to fix these minor problems with sanding and other tools.
