Using the right tools is essential to do the job successfully. There are some necessary tools that every repairman needs to have on hand, including sanding sponges, a mud container, a putty.
Knife, joint compound, and drywall patch kits.
If you are repairing minor dents or scratches less than ½ inches, use a layer of joint compound to fill them. Apply the material with a 3—or 4-inch putty knife designed for drywall repair. If the cracks or holes are larger, force them with mesh before caulking.
Don’t complicate the task
Use ready-made products designed to simplify drywall repair. Self-adhesive patch and tape repair kits with reinforced center panels are an excellent solution for repairing small holes. A combination of primer and drywall compound provides a paint-ready wall.
Focus on the finish
Homeowners often ruin the aesthetics of the wall even after using expensive equipment. Use a utility knife or sharp cutting tool to remove frayed drywall edges around cracks or dents. Finish the job before applying the joint compound to hide any imperfections.
Do not cut electrical wires or plumbing pipes.
Before you begin drywall repair, check for electrical wires and plumbing lines through the wall. Otherwise, you might end up cutting them. If you need to repair a hole a few inches wide, use a flashlight to see what’s behind it. Be sure to act safely without making assumptions.
Apply a thin coat
A thin coat of joint compound provides a clean, finished surface for painting. Plus, sanding the wall is easy without accidentally exposing the patch. As you apply, level the mud gently to ensure a smooth finish. Hold the knife at a 70-degree angle and press it harder on the outer edge of the mud as you move away from the center.
Don’t cut corners when sanding
Although the joint compound hides all surface imperfections, it becomes hard and uneven after drying. This makes it essential to sand the repair site properly. Begin sanding when the area is dry. After sanding the first coat, apply a second coat of compound that is two inches wider than the first. Once the second coat dries, repeat the process if necessary.
Use protective equipment
Drywall compounds contain fine particles that can cause health problems if inhaled. Drywall repair experts recommend using a quality dust mask when performing the task. Plaster dust can dehydrate the skin, so you should consider wearing disposable gloves to protect your hands.
