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"Our bathroom was outdated and cramped, so we decided to remodel with Ocean Seven Builders.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

If your premixed drywall mud is dried out or has begun to set in the bucket, you may be able to revive it by adding warm water and stirring. However, the first and most important step is to scrape off any hard, dried bits of drywall that may have accumulated toward the top of the container and throw them away because they will not easily reconstitute back into the drywall mud mix.

Damp plaster does dry out, although the drying time depends on several factors, including the type of plaster, the surrounding temperature, moisture content, and the extent of the dampness. Sometimes, it can take weeks or months for wall plaster to dry naturally.

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.

Plastering lasts for around 15 to 20 years without needing repairs or maintenance in most cases, and with proper upkeep, plastering can last a lifetime—sometimes more than 100 years. Plaster repair costs between $1 and $3 per square foot, and you may need these services once every 15 to 20 years or so unless you have a harsh climate where humidity changes are a constant issue. You can also opt to skim-coat plaster for between $0.90 and $1.30 per square foot, which may serve you better in the long run.

You can plaster over regular drywall, but it's essential to prepare the surface properly. Before plastering, the drywall should be clean, free of dust, and any loose or peeling paint should be removed. Applying a primer specifically designed for plastering can improve adhesion. Some professionals recommend applying a base coat of plaster or joint compound to create a better surface for the plaster to adhere to. Proper preparation ensures a smooth and durable plaster finish over regular drywall.
