Question 1

What tool is used to sand plaster?

Accepted Answer

•

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.

Question 3

How do I know if I have plaster walls?

Accepted Answer

•

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.

Question 4

Why use metal corners on drywall?

Accepted Answer

•

Metal corners, often referred to as corner beads for square corners, are used on drywall installations to provide structural reinforcement to vulnerable outside corners. Their usage safeguards against chipping, denting, or other forms of damage, enhancing the overall durability of the wall. Metal corners also offer a precise and straight edge that facilitates sharp and clean lines, crucial for achieving a polished and professional finish.

Question 5

How much water does it take to damage drywall?

Accepted Answer

•

Very little. One inch of water can stain walls, warp wood, and create a perfect environment for mold growth. One to two inches of water can do significant damage to drywall, insulation, and electrical systems. Anything over that is considered an extensive flood, often resulting in severe structural damage.
