Drywall Insulation questions, answered by experts

Drying alone can take 1 to 4 hours to dry to the touch per plaster layer, but some types of plaster take several hours longer to dry. However, this doesn’t mean the job is done because plaster doesn’t fully harden until it cures, which can take a few days to a couple of weeks. It may take even longer if you’re building a new, pretty thick plaster wall. Allow the plaster to cure before painting it.

Whether you need a drywall anchor depends on the specifics of your project, particularly what you're hanging and where. You do not need a drywall anchor if you can screw or nail the object directly into a wooden stud, as the wood provides sufficient support and stability. However, if there are no studs in the location where you plan to hang the item, you should use drywall anchors to ensure it is securely supported. For very lightweight objects, like small pictures, adhesive picture hanging strips can be a suitable alternative to anchors.

The easiest way to cut holes in drywall for electrical boxes is to use a spiral saw with a drywall router bit. Hang the drywall without cutting out a hole for the box, but make sure you measure and mark where the box is located on the wall. Once you screw in the drywall sheet, drill a small hole into the box void, insert the spiral saw bit, and move it around the edge of the box using the inside wall as a guide. You can also use an oscillating multi-tool with an electrical box cutout for fast, professional results.

Drywall repair is typically completed within a day, depending on damage extent.

Yes, drywall can hold a 50-pound TV. However, when mounting a TV, you’ll either need to attach it to wall studs or use drywall anchors. If you use anchors, make sure to buy a type that can hold at least 50 pounds. Molly bolts, threaded anchors, and toggle bolts are all good options. For extra support, you can also install a wall mounting plate with the anchors.
