"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"Our bathroom was outdated and cramped, so we decided to remodel with Ocean Seven Builders.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

Repairs typically take 2-4 hours for small areas. Larger or more complex repairs may require additional time.

With its breathability and flexibility, lime plaster is among the most durable of all plaster types. It's also fire-resistant and has a proven track record, as people have been using it for thousands of years.

However, all plaster types will last for many years with the right care and treatment. Proper preparation and installation will also help ensure your plaster walls look great for as long as possible.

To maintain plaster walls, inspect them regularly for cracks and seal them early. Clean the walls by dusting regularly or using a gentle, damp cloth. It's also important to avoid moisture exposure. Repainting as needed will help maintain the wall's appearance and longevity.

While it’s most common to sand plaster dry, it is possible to wet-sand plaster, too. Doing so can reduce the amount of plaster dust released into the air and make it easier to work in smaller, more delicate areas (such as around wall trim). However, some people find that wet sanding leads to more imperfections, which is why larger walls are more often dry sanded to ensure an even finish.

It may take a bit of patience and trial and error to match your particular drywall texture type when making repairs. For orange peel or knockdown finishes, use a spray texture product or a thinned joint compound applied with a roller or sponge. Practice on scrap drywall or cardboard first. Once dry, lightly sand and prime before painting.
