Whether there are cracks in the concrete, plaster, and drywall, we can all agree that they are such eyesores. These cracks are commonly caused by settling of the house which naturally happens over time. The good news is; you can repair a hairline crack easily. You can use simple materials and tools you have at home or purchase at a local hardware store.
However, if the surface or wall has a huge and horizontal crack, the damage is already severe. Other types of cracks are also other signs of a potential structural problem. If you notice a not-so-simple crack, hire a professional of foundation repair Sherman TX.
1. Cracks on Drywall
One of the easiest crack repairs you can do at your house are the ones on the drywall. Grab a utility knife and cut a 1/8 inch V-notch along the crack’s length. The loose materials should be vacuumed out. Use a joint compound or mesh joint tape to cover the crack. Follow this with a joint compound (thin layer only) and make it extend on each tape’s side for about 2 inches. Allow to dry before applying a second coat of the compound which should be about 7 inches to the crack’s side. Dry again for about 12 hours. Now the cracks are gone and your drywall is ready to be painted once again.
2. Cracks on Plaster Wall Patching
If there are cracks on the plaster wall, you can treat them the same way you treated the cracks on the drywall using a joint compound. But if the plaster is moving away from the lath, you have to do a two-step process first to shore up the wall. First, drill holes that penetrate the plaster. Vacuum the debris and dust. Spray the hole with an adhesive conditioner. Begin injecting the holes with the adhesive, staring from its lowest point. Use a damp sponge to clean the excess adhesive.
Use a drill to attach the plaster rings so you can pull the plaster up to the wall. Remove the rings. Use a joint compound to hire the original cracks and the holes too. Sand the surface lightly and apply a joint compound for the second coating. When the surface is already dry, sand smoothen it.
3. Cracks in Concrete Walls
If you noticed cracks in your concrete walls, you will need an epoxy repair kit to repair the cracks. First, you have to tap finish nails into the crack so you can attach the injection ports later. The epoxy has two parts and you will have to mix before you can use them. Use a putty knife to mix equal parts of the epoxy. Apply a mixed epoxy on each injection port tab (which should be small portion only). Cover each finished nails to attach the port on the wall. Apply the epoxy mixture on the crack. Allow to cure for about 10 hours. Inject liquid concrete repair by using a caulk gun into the ports. Allow to cure for 5 days/
