While it’s most common to sand plaster dry, it is possible to wet-sand plaster, too. Doing so can reduce the amount of plaster dust released into the air and make it easier to work in smaller, more delicate areas (such as around wall trim). However, some people find that wet sanding leads to more imperfections, which is why larger walls are more often dry sanded to ensure an even finish.

Which style of corner bead you choose—whether metal or paper-faced—depends on your preference and if you’re comfortable using metal-cutting tools and a hammer. Metal bead offers superior strength and durability but its installation is slightly more involved. We’d say for most cases, it’s better to use metal bead but if you’re not comfortable working with metal, paper-faced bead will work just fine. 

If your home was built before the 1940s and was not remodeled in the past 50 or so years, you probably have plaster walls. Aside from assuming, there are some practical ways to tell if you have plaster walls, including the following: If you knock on the wall and it feels solid, not hollow, if you can’t insert a thumbtack easily, if there are cracks that look like spiderwebs, or if your home has curved, arched, or swirled walls, doorways, or window openings.

If you have an unfinished basement or attic, you could examine the backs of any finished walls to check, too.

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.
