The most common problems in plaster repair are cracks that appear due to structural changes in the building, or old plaster that pulls away from the lath and seems to bulge. Before beginning the repair, Commonwealth Painting Company will inspect the situation to determine the cause of the damage. Structural repairs may need to be made before the plaster is repaired. In many cases, we can make minor carpentry repairs to correct the situation, or if necessary, contract building specialists for severe structural damage.

After the cause of the damage has been determined and eliminated, all loose plaster is removed from the wall surface. Drywall tape is applied to the area of the crack and drywall compound applied to fill in the crack. After drying, the compound is sanded and additional coats of compound added to create an even surface. The new surface is then painted with primer and caulked before the finish coat of paint is applied.

In some instances, a minor surface flaw is only an indication of much more damage underneath. In the example below, a small blister near an air conditioning vent required a large section of drywall to be removed due to excess condensation build-up around the vent, inside the wall. A new section of drywall was installed, taped, and compounded, leaving an invisible repair job after the wall was painted.
