"Project: Repair and partially replace stucco surface of small retaining wall. Phil met with me and we discussed how to treat a short retaining wall that was losing the stucco surface after about 4 years since it was originally plastered. The wall was alowing water seepage to come thru the concrete block and lifting the original stucco finish off. Phil suggested a repair , consisting of first scraping all loose stucco off the wall and then applying an adhesive type undercoat followed by a total restucco of the wall. It was done very professionally , minimal debris, 2-day process , and it looks great. Now I just have to see how it holds up over the next 4-5 years . Highly recommend PG Plastering."

"Our bathroom was outdated and cramped, so we decided to remodel with Ocean Seven Builders. Ron was involved throughout the process and made sure we understood each step. What stood out most was how organized everything felt once the work began. The team was respectful of our home and finished the project close to the expected timeline. The final result looks modern and much more functional!"

Plaster Repair questions, answered by experts

Yes, you can speed up the time it takes for plaster to dry, but it's important to do so carefully to avoid issues like cracking or crumbling. Proper ventilation is key; open a window or use a fan to circulate air in the room. Heat can also accelerate drying, but be cautious, as too much heat can cause the plaster to dry too quickly and crack. Check the plaster's packaging for the recommended drying temperature and set the room's thermostat accordingly. While managing humidity is important, avoid using a dehumidifier, which can remove moisture too aggressively and result in crumbly plaster.

While you should consult with a ceiling professional for larger cracks, especially if you’re not sure what’s causing your ceiling to crack, you can certainly try to repair small cracks on your own. If you’re up for the task, here’s how to repair ceiling cracks for $150 or less.

Costs range from $200 to $800, depending on the area size and damage severity.

While it is possible to repair minor plaster cracks or holes yourself, it is generally not recommended for larger jobs or if you want a professional result. Plaster repair can be difficult in practice; proper wall preparation and achieving a smooth, seamless finish that blends with the existing wall requires experience, especially on textured surfaces. Hiring a professional ensures the repair will be durable and last longer, potentially saving you money over time. A pro can also determine if the cracks are from normal expansion or a more serious underlying issue.

The tool you use to sand plaster will depend on the size of the project. If you’re just working on a small section of your wall to get rid of an uneven spot on the surface, hand-sanding might work. However, for larger projects, a drywall sander can make a huge difference when it comes to both time and elbow grease—and an orbital sander can help for detailed areas such as around ceiling fans.
