Plaster Repair questions, answered by experts

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.

Repairing plaster walls or ceilings is almost always worthwhile. It restores the appearance of your home, and if it's an exterior wall, the repair can improve curb appeal and provide a great return on investment when selling. Plaster repairs can also reinforce the wall, preventing minor cracks from spreading, and improve your home’s energy efficiency by fixing gaps in the insulative material, potentially lowering your heating and cooling bills. Additionally, hiring a professional allows them to check if the damage is from a serious underlying issue, such as foundation instability. Catching a problem like this early could save you thousands.

How long it takes to repair a ceiling depends on the extent of the damage. Patching a small hole might only take a few minutes, while repairing a water-damaged section of the ceiling could take hours. If there are structural issues, expect your ceiling repair to take several days or longer.

Plaster walls typically last between 30 and 70 years, but depending on the quality of the materials and the moisture levels in the building, they can last for over 100 years. With expert application and consistent maintenance, plaster can even last for centuries. To extend its lifespan, it is important to have the plaster professionally installed, address any water damage promptly, and repair small cracks as they appear. Regular inspections by a professional can help identify and address concerning cracks before they become significant issues.
