Plaster is moderately easy to repair for DIYers. While it takes some patience and technique compared to standard drywall, cosmetic fixes like filling small holes and hairline cracks are very straightforward. Extensive structural damage requires more work, such as injecting adhesive to reattach loose plaster to the wooden lath behind it.
If you have holes or cracks in your plaster walls or ceilings, repairing them isn't difficult. It can, however, require a bit more extra time and skill than patching a hole in drywall.
We cannot use gypsum plaster for outer walls. These retain dampness and are not the most suitable for areas with walls that come in regular contact with water, such as bathrooms and toilets. Even though there are modified water-resistant, they do not perform as well as cement plaster.
On average, plaster can last anywhere from 15 to 20 years if it's well-maintained and hasn't been exposed to excessive moisture or damage. However, this lifespan can vary depending on the quality of the plaster, how it was applied, and environmental factors like humidity or temperature changes.
In some cases, if the plaster is severely damaged beyond repair, it may be necessary to remove the old plaster and start fresh. However, this is not often necessary. By following the proper steps to prepare the wall and applying the plaster correctly, plastering over old plaster can be a simple and successful process.

Lath and plaster was a skilled craft and a time-consuming technique and the advent of cheaper, mass produced, pre-manufactured plasterboard meant lath and plaster largely fell out of favour by the 1930s and 1940s. Plasterboard was simply faster and less expensive to install.
Plastering Cost per Square Metre
The average plastering cost per m² in 2025 is around £15–£80, depending on the work type and finish. A basic skim coat over existing plasterboard usually costs £15–£25 per m², while a full two-coat replaster ranges from £30–£50 per m².
