It is possible to apply plaster on the interior or exterior of your home, but we don’t recommend it. Plaster is easy to apply in theory, but in reality, it can be a challenging material to work with, and it’s difficult to get the finished product to look clean, even, and smooth. Many DIYers end up calling in a professional afterward to touch up the area or even redo it entirely because of mistakes they made in the process. Hiring a plaster pro will cost more, but it’s usually the best option to achieve high-quality results.

The short answer is yes, a sagging plaster ceiling is dangerous. Sagging plaster on a wall is something you should fix immediately, but it isn’t a major concern. If the same type of sagging occurs on a ceiling, however, you could be in danger of your ceiling falling in large chunks. When plaster sags, it loses its strength and ability to hold itself up. The bonds that hold it together are strong, though, so if a sagging area falls, it will take large pieces down with it.

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.

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.
