Drywall Insulation FAQs, answered by experts

It doesn’t matter which way you lay drywall, and you can choose to install it horizontally or vertically depending on the size of the wall and how tall the ceiling is. It’s easier to lay drywall sheets vertically if you have a taller ceiling, but laying sheets horizontally makes it easier to apply joint compound.

The tool you use to sand plaster will depend on the size of the project. If you’re just working on a small section of your wall to get rid of an uneven spot on the surface, hand-sanding might work. However, for larger projects, a drywall sander can make a huge difference when it comes to both time and elbow grease—and an orbital sander can help for detailed areas such as around ceiling fans.

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. 

Vinegar and bleach are effective options for removing mold from drywall. Vinegar is a better choice if you have a smaller mold issue while bleach is best if you have a larger mold problem. If the area you're cleaning has limited ventilation, using vinegar would be a better option. In that case, you could mix vinegar with baking soda to remove more stubborn mold growth.

You should always hang drywall from the top down. Starting at the top makes it easier to create a straight, tight line between the ceiling and the wall. Any gaps that occur will be at the bottom, where they are easier to manage. You can either cut the bottom piece of drywall to fit the remaining space or cover the gap with baseboard trim. Additionally, starting at the top is physically easier, as you won't have to fit the top sheet into a tight space between the lower sheet and the ceiling, or try to balance the upper sheets on the lower ones while securing them.
