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.

Whether you need drywall anchors depends on your specific project, particularly where you are hanging an item. Drywall anchors are not necessary if you can drive a screw directly into a wooden stud behind the wall, as the stud provides sufficient support. However, since studs are not present everywhere in a wall, you will need to use drywall anchors if you are hanging an object in a location without a stud. For very lightweight items, picture hanging strips can also be a suitable alternative.

You can paint over plaster, but repair any damage to the plaster first, or the paint will crack and bubble. You should also prepare the surface of the plaster to accept paint, which gives your paint job the best chance of looking good and lasting a long time. Before applying the color you want, apply a coat or two of primer. Additionally, use latex paint, and choose a latex paint with a satin finish for areas with dampness, like bathrooms.

Whether a drywall anchor can be reused depends on its material, type, and the method of removal. Plastic anchors, including expansion and self-drilling types, are generally designed for single use as they tend to break or deform upon removal. Metal anchors, such as toggle bolts, are more durable and may be reusable if they are not damaged during extraction. However, with toggle bolts, the toggle piece can fall into the wall cavity when the bolt is removed, making it difficult to retrieve. If an anchor is damaged during removal, for instance by having its head cut off, it cannot be reused regardless of the material.
