Can I Use Drywall Mud To Repair Plaster Walls. Drywall mud, or joint compound, is used to smooth joints in walls and ceilings before they're painted or wallpapered. Cold or humid climate use dry bag.
Many walls and ceilings in modern construction are made from sheets of drywall, also known as gypsum wallboard.
If needed, apply drywall/plaster tape to the wall to fill in larger, bumpy areas. Use a cloth or rag to wipe away dust and debris. I like to hunt down weird questions about plaster and give informed answers to prevent the future generations from messing up their how can i keep leftover drywall mud from drying out in the box?
