Drywall FAQs, answered by experts

A common cause of separation between a wall and the ceiling is truss lift—this can happen to the ceiling of rooms directly under the attic when the seasons change and wood building materials dry out, shrink, and shift. Roof trusses often dry out at different speeds, and if the bottom pieces dry out faster than the top pieces, they can shrink and pull the attached drywall away from ceilings and walls, causing cracks. Fortunately, truss lift is only a cosmetic problem, not a structural problem, and you can fix it by separating the ceiling drywall from the roof trusses, and patching the cracks.

If you’re installing new drywall, you may need to skim coat the drywall first for a smooth finish and to allow the primer to adhere to the wall. It’s only necessary if there are imperfections in your drywall due to issues with the studs or improper drywall installation. If you’re refreshing existing walls, you may want to skim coat if there are imperfections across the wall. As an alternative, you can repair your drywall and sand it for a smooth finish before painting.

Yes, wainscoting is installed directly over drywall. However, ensure the drywall is in good shape since it will support the wainscoting. If the drywall has issues, such as holes, mold, or mildew, repair them before installing the wainscoting. Alternatively, you can install a plywood substrate before attaching the trim.

Yes, you can speed up the time it takes for plaster to dry, but it's important to do so carefully to avoid issues like cracking or crumbling. Proper ventilation is key; open a window or use a fan to circulate air in the room. Heat can also accelerate drying, but be cautious, as too much heat can cause the plaster to dry too quickly and crack. Check the plaster's packaging for the recommended drying temperature and set the room's thermostat accordingly. While managing humidity is important, avoid using a dehumidifier, which can remove moisture too aggressively and result in crumbly plaster.

There are some instances when you can use extra drywall in your garden. Ideally, unused scraps of new drywall are best for amending soil without the concern of additional chemicals or mold. However, drywall with paint, mold, or potential asbestos requires specialized disposal by a professional and should be kept out of your garden.
