Generally, though, standard drywall mud takes about 24 hours to fully dry. However, if you’re using ‘hot mud’, it can speed things up considerably. Patience is a virtue, my friends!

Factors That Affect the Drying Process

Several factors influence the drying time of drywall mud. Room temperature and humidity play a considerable role.

Other Recommended Maintenance

Now that you know about how long drywall mud takes to dry, let’s look at some other areas of recommended maintenance. One of those is insulating interior walls. If you are buying a home, you want to make sure the interior walls are insulated. This keeps out noise, and sound, creates higher energy efficiency, and also fire control.

Another is painting. If you are painting the exterior of the home, you need to make sure you use exterior paint. You can’t use this indoors as the fumes are toxic. If there is a color you like, then make sure you buy it as an interior paint if that is what you want to use it for.

Lastly, many wonder when to use joint compound or spackle. Joint compound is used on larger projects, while spackle is used on smaller ones. Joint compound takes a lot longer to dry than spackle.
