Question 1

How do you prevent dust when sanding drywall?

Accepted Answer

Minimize dust by using fine-grit sandpaper (150-220), sanding with light pressure, and using a pole sander with vacuum attachment or HEPA shop vacuum nearby. Seal off the work area with plastic sheeting and close HVAC vents to prevent dust spread. Wet sanding with a damp sponge eliminates most dust but can be tricky—too much water roughens the surface. For large jobs, rent a power sander with built-in dust collection. Always wear a dust mask, and plan to thoroughly clean the area afterward with a HEPA vacuum.

Question 2

What causes efflorescence on drywall?

Accepted Answer

Efflorescence appears as white, powdery deposits on drywall surfaces, indicating water infiltration bringing dissolved salts to the surface. It's more common on basement walls or areas with foundation moisture. Address the moisture source first—efflorescence is a symptom, not the problem. Clean deposits with a dry brush or HEPA vacuum. Seal the surface with moisture-blocking primer before repairing and painting. If efflorescence returns after repairs, you haven't fixed the underlying moisture issue. This may require professional waterproofing or foundation work.

Question 3

What causes drywall cracks?

Accepted Answer

Drywall cracks typically result from house settling, temperature fluctuations, humidity changes, or structural movement. Horizontal cracks often appear at weak points like door frames or where walls meet ceilings. Vertical cracks usually indicate normal settling, while diagonal cracks may signal foundation issues. Even new homes experience minor cracking as the building materials adjust and settle during the first few years.

Question 4

Can you repair drywall in a rental property?

Accepted Answer

Yes, tenants can repair minor damage like small holes and nail holes, though you should check your lease agreement first—some landlords prefer to handle all repairs. Document damage with photos before and after repairs. Use standard repair techniques for quality results that won't cause issues at move-out. For larger damage or anything related to structural issues, water damage, or mold, notify your landlord immediately rather than attempting repairs yourself. Improper repairs can result in security deposit deductions or charges for professional fixes.

Question 5

Can you repair drywall with duct tape?

Accepted Answer

Duct tape isn't appropriate for drywall repairs. It doesn't adhere well to drywall surfaces long-term, shows through paint, and peels off eventually. For proper crack repairs, use fiberglass mesh tape or paper tape embedded in joint compound. Duct tape might work as temporary covering to prevent debris from falling through holes until proper repairs can be made. Never consider duct tape a permanent solution—it always fails and looks unprofessional. Use materials specifically designed for drywall for repairs that last.
