Fixing a damaged corner bead

Filed under: House Remodelling — Gilles @ 9:45 pm

Corner beads wil get damaged over time. It is easy to hit them with furnitures when moving in or out. Today, I’ll show a step by step technique to fix damaged corner beads. This procedure is well within reach of a typical homeowner.

Step1: Assess the situation. There are multiple kind of corner beads: metal or plastic are the two most common. We will concentrate on metal corner beads. Is the bead bend or torn or cut? Is the bead still firmly anchored to the wall or not? It is possible to repair all these but in this post, I’ll concentrate on bent beads still firmly attached to the wall. This is the vast majority of cases.
For instance, on the picture below, you can see a bent metal bead. It is well attached to walls:

Step 2: Using a light hammer, gently tap the bent section of the corner bead to align it with undamanged parts of the bead. Be gentle with the hammer. Tap gently to avoid separating the bead from the walls. After all, you do not want to reinstall the whole bead. Only fix a small section. The following picture shows the now straight corner bead. I have also removed all loose pieces of compound.

Step 3: Using a small putty knife, fill in the damaged area with spackling paste or all purpose joint compound. Don’t try to get a perfect job, you are just trying to fill in most of the crack. Remove excess paste with a damp sponge and wait for the paste to dry completely. Since you need to fill in cracks by layers, repeat this step until the crack is completely filled in. Remember that layers must dry completely before you add more paste. The following picture shows the first layer: I have filled most of the holes but the result is not yet perfect:

Step 4: Lightly sand the repaired area (220 mesh or 220 sand paper). Some prefer to use a damp sponge: it leaves less dust and works almost as well. If your wall is textured like the one on my picture, you might need to add texture to the repaired area so it is less noticeable (a flat area on a textured wall catches eyes).
Step 5: Prime and paint to finish the repair.
