Plaster Repair & Restoration

Why plaster cracks and how serious it is

Plaster cracks from house settlement, temperature swings, vibration and loss of the keys, the plaster that pushes through the lath and holds the coating. Hairline cracks are cosmetic, while bulging, sagging or crumbling areas signal that the plaster has separated from the lath. A plasterer taps the wall to find hollow spots and checks for moisture, which is a common cause of failure. Fixing the underlying issue prevents repeat cracks. Get the key details in writing, including materials, timing and what is and is not included, so everyone is working from the same expectations.

Repair methods: keys, patches and skim coats

Small cracks are cut out, filled with setting compound and finished. Loose plaster can be reattached with plaster washers or adhesive and screws before filling. Larger holes are patched with new lath and plaster layers, and badly cracked walls may be skim coated to produce a uniform, smooth surface. Matching the original texture and thickness takes experience. Where possible, preserving existing plaster maintains the character of the home and its sound and fire resistance. If you are comparing quotes, line up the scope, materials and schedule side by side, because the lowest number is not always the same job.

Moldings, historic homes and painting afterward

Ornate crown moldings, ceiling medallions and arches can be repaired or re-cast to match. Historic houses may have lime plaster, which needs compatible materials. After repairs, prime with a good primer made for fresh plaster before painting, and give the surface time to cure. If your house has lead paint, take precautions during sanding. A plasterer can advise on safe practices and test kits. Plan for a little flexibility in the schedule, since weather, deliveries and inspections can shift the timing of a project. Ask what maintenance the finished work needs, and how often, so you can protect your investment and avoid avoidable repairs.
