Why is my joint compound cracking?
The most common cause of cracking in freshly applied drywall mud is when it is applied too thickly. This exacerbates the issue with evaporation-based drying and can even crack curing compounds. Past this point, applying more drywall mud will cause the cracking to worsen if done improperly.
