Cracks in the plaster could mean that it is worn out and needs some repair. However, in some cases, it could mean that there are serious issues with the houses structural frame, which would need serious repairs. Before carrying out plaster repairs, you need to contact a competent contractor and make sure that there aren't any deeper underlying issues that need to be fixed. It is also advisable to understand the common mistakes which people make when handling the repairs so that you can avoid them in the process.
Filling the Plaster without Patching
Not many people understand that there is a huge difference between filling cracks in the plaster and making complete repairs. Filling the break means simply pressing a plaster joint into a damaged place and sanding down the area until it is smooth. The repair is then quickly repainted. Patching is different and better because it involves replacing the missing chunks with new material, then use the lathing for support. It is recommended, if the damage is extensive, to patch instead of fill it.
Removing Old Plaster
The second mistake that people make when repairing their damaged roof and ceiling is the failure to check the extent of the damage to map out how much repair they need to do. If the damage is more than a simple crack, it is advisable to move the stucco around to create room for the repair. If the plaster around it gets soft, you will have to replace it. It is, therefore, advisable to cut away a good portion of the plaster compound to leave room for the patch.
Failure to Blend
The other major mistake that people make when handling DIY repairs is the failure to blend in the new material with the old. New plaster might end up looking uneven or splotchy when it is not properly blended in with the old plaster that has dried up. It is advisable to add a drywall tape along the edges of the patch to create an invisible seam between the new and the old section. Check whether the two parts are even and either sand down or add plaster to the patch as needed.
Patching and filling are simple ways that you can repair and restore the appearance of your ceiling and wall moulding. However, it needs to be done with a lot of caution. If you are not sure you can handle the project successfully as a DIY, call in a restoration expert to handle the plastering process for you.
