As your hose undergoes the natural process of settling, cracks can appear that need to be repaired with a plaster patch. Fortunately, this is generally a job that you can undertake yourself. Follow this simple guide to learn how to purchase the right patch material and apply it yourself.

Before you go to purchase your supplies, take a look to see what you already have. You may already have many of the tools needed to do a plaster patch repair in your tool box or utility closet. Also, check to see if you have fine sandpaper and a container you can use to mix the material in.

How Much Damage is There?

Survey the damage before buying repair materials. If you just have a small crack, you can patch this using a plaster pencil. A small hole can be repaired with spackling compound. Larger areas of damage will need a plaster material that can be used for larger areas, a pencil or compound usually won’t cut it. The patching material is not hard to work with, but it will require mixing and measurements.

Working with Patching Materials

Depending on the finish of your walls and the extent of the damage you will have several different options for the material you use. A spackling compound has a mud-like texture and is fairly simple to use. Plaster patch materials are powders that must be mixed prior to use. They are similar to the Plaster of Paris. General patching materials can be found in putty, tapes, and epoxies. You will need to figure out what product will work best for the damage you have. If you’re unsure, ask an expert at the hardware supply store, or go with the plaster patch since it’s easy to use.

Repairing Cracks

A hairline crack can't be patched in traditional ways since it needs to be able to adhere to something. Before you can start using any kind of compound, you will need to clean out the crack as best as you can. You will want to widen the crack slightly so you can get enough plaster in the crack to form the patch. Use a putty knife to get the plaster material inside the crack first. Once this is done allow 24 hours for it to dry, then apply a layer over the crack and smooth it out to match the rest of the wall.

Repairing Holes

Start by cleaning the area around the hole to ensure you have removed all the loose plaster. Carve under the edge of the broken area, this will give you a good seat for the material. Get the edge of the hole damp and fill the area with patching material. You will want to leave enough room to be able to apply another layer later and smooth it over. Allow 24 hours for it to dry, then apply joint compound to the surface. Spread this over the wall beyond the original patch. You can sand the wall to make it even where it was patched.
