Drywall Insulation questions, answered by experts

You should wait at least 24 hours for drywall mud to dry before sanding or applying another coat. However, the exact drying time depends on several factors, including the thickness of the application, room temperature, humidity, and the type of compound used. Thicker layers, or projects in high humidity, may require 48 hours or more. Lightweight compounds tend to dry faster than heavier, all-purpose ones. You'll know the mud is ready when it feels completely dry and firm to the touch and has changed to a consistent light color. Sanding too early can cause smudging or gouges, so patience is essential for a smooth finish.

The short answer is yes, a sagging plaster ceiling is dangerous. Sagging plaster on a wall is something you should fix immediately, but it isn’t a major concern. If the same type of sagging occurs on a ceiling, however, you could be in danger of your ceiling falling in large chunks. When plaster sags, it loses its strength and ability to hold itself up. The bonds that hold it together are strong, though, so if a sagging area falls, it will take large pieces down with it.

When you are learning how to tape and mud drywall, waiting for things to dry requires a lot of patience. So how long does drywall mud take to dry? On average, it takes about 24 hours. However, it depends on things like the thickness of the mud, as well as the room’s temperature, humidity, and ventilation. Using thin layers of mud in a warm, low-humidity room with good airflow reduces average drying time. You also could speed up drying time by making use of hot drywall mud, which consists of a powder that you mix with water, instead of using pre-mixed mud. 

Whether it’s better to screw or glue drywall depends on your specific budget and project timeline. Professional drywall installers are more likely to use screws and fasteners than adhesives, but it takes longer. But if you are DIYing your drywall installation, glue is a perfectly fine choice if you’re willing to pay extra for adhesive.

Whether you need drywall anchors depends on your specific project, particularly where you are hanging an item. Drywall anchors are not necessary if you can drive a screw directly into a wooden stud behind the wall, as the stud provides sufficient support. However, since studs are not present everywhere in a wall, you will need to use drywall anchors if you are hanging an object in a location without a stud. For very lightweight items, picture hanging strips can also be a suitable alternative.
