Drywall Insulation FAQs, 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.

Drywall is safe to cut as long as you follow proper procedures, such as wearing personal protective equipment and using the right tools to score and cut the drywall. When cutting new drywall, it can release dust with silica and other compounds that could pose health risks. Leave cutting drywall to the pros, or wear a high-quality respiratory mask, goggles, and other PPE when handling drywall.

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.

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.

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.
