Plaster Repair questions, answered by experts

It’s not a good idea to plaster over broken plaster (unless by broken you’re referring to cracked, in which case that’s perfectly fine). However, broken plaster can be a sign of a larger underlying issue like foundation damage or severe damage to the lath holding up the plaster, so it’s worth investigating before you simply plaster on top of the damage.

Common causes of ceiling cracks along drywall seams include poor drywall installation techniques, structural issues, truss uplift, and foundation problems. Temperature and humidity also play major roles in ceiling cracks flush with the wall. As the drywall shrinks and expands from major temperature changes or extreme humidity shifts, this can cause the drywall to crack.

You can apply plaster over plaster, but before you do, check the stability of the existing plaster. If it’s been there for a while, it may require a base coat of PVA emulsion. This will make the existing plaster less porous and ensure the new and old plaster adhere properly.

Regular inspections and cleaning to prevent moisture or pest issues.

Many services include repainting to match the existing surface. Confirm with your provider.
