The biggest downsides of plaster walls are cost and repair difficulty. Plaster installation requires skilled labor and more time than drywall, making it a more expensive option upfront, and repairs are more complex if damage occurs.
Other downsides include:
- Longer installation time due to multiple coats and drying periods between layers
- Higher risk of cracking over time, especially in homes with foundation settling
- More difficult and costly repairs compared to simply patching drywall
- Limited availability of skilled plaster tradespeople in some areas
- Heavier material, which can add weight considerations in some structural situations
Despite these downsides, plaster’s durability and finish quality make it a worthwhile investment for certain projects, particularly restoration work or homeowners specifically seeking its aesthetic and soundproofing benefits.
For most standard residential projects, these downsides are why drywall remains the more practical and widely used choice, while plaster is reserved for specific design or historical goals.
