Drywall Insulation questions, answered by experts

You can drywall an unheated garage because the material handles cold temperatures perfectly well. There are no risks or downsides to installing drywall in a garage that is not heated, and the material stands up to moisture and other elements quite well. Drywall will protect your unheated garage's electric wires and cables and add fire protection. However, for effective bonding, you should install drywall at a temperature of 55 degrees Fahrenheit or higher.

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.

You may need to replace drywall because of smoke damage. If the drywall is covered in soot, you may be able to clean it, but it will require a lot of time and effort. You could spend hours cleaning the drywall only to find there is more damage and it needs to be replaced anyway. It’s usually easier and safer to remove the smoke-damaged drywall and replace it.

Yes, you can hammer a nail into a wall stud. But before you do, it’s important to confirm that you’re actually nailing into a stud—and not wiring, pipes, or ductwork. To check, find a few more studs in the wall, then measure to make sure they’re either 16 or 24 inches apart.

With its breathability and flexibility, lime plaster is among the most durable of all plaster types. It's also fire-resistant and has a proven track record, as people have been using it for thousands of years.

However, all plaster types will last for many years with the right care and treatment. Proper preparation and installation will also help ensure your plaster walls look great for as long as possible.
