When it comes to home improvement projects, one common issue that many homeowners encounter is repairing damaged walls. Whether it’s due to a doorknob hitting the wall or an accident during a DIY project, holes and cracks in the wall can be unsightly and detract from the overall appearance of your home.
One popular solution for fixing damaged walls is to use plaster. However, there are different types of plaster available on the market, and it can be confusing to determine which one is right for your project. In particular, many people wonder whether patching plaster is the same as Plaster of Paris.
What is Plaster of Paris?
Plaster of Paris is a type of gypsum plaster that has been used for centuries in construction and art projects. It gets its name from the fact that it was first discovered in a large deposit near Paris, France.
Plaster of Paris is made by heating gypsum rock to remove the water content. The resulting powder can be mixed with water to create a paste that hardens quickly when applied to a surface. This makes it an ideal material for creating molds or casts, as well as for filling holes or cracks in walls.
What is Patching Plaster?
Patching plaster is another type of gypsum-based plaster that is specifically designed for repairing damaged walls. It typically comes in pre-mixed tubs or bags and can be applied directly to the surface using a trowel.
One key difference between patching plaster and Plaster of Paris is that patching plaster contains additives like acrylics or polymers that help improve its adhesion properties and prevent cracking. This makes it better suited for filling larger holes or cracks than Plaster of Paris.
So, are they the same thing?
While both Plaster of Paris and patching plaster are made from gypsum rock, they are not interchangeable materials. If you’re trying to repair damaged walls, it’s important to choose the right type of plaster for your specific needs.
If you have smaller holes or cracks, Plaster of Paris may be sufficient for your project. However, if you’re dealing with larger areas of damage or want a more durable repair, patching plaster is likely the better choice.
How to Patch a Wall with Plaster
If you’ve decided to use Plaster of Paris to repair a damaged wall, here’s a step-by-step guide to help you get started:
- Using a putty knife or scraper, remove any loose or crumbling plaster from the damaged area.
- Use sandpaper to smooth out any rough edges around the hole or crack.
- Prepare the Plaster of Paris according to the manufacturer’s instructions. You’ll typically need to mix it with water until it has a smooth, creamy consistency.
- Apply the plaster mixture to the damaged area using a putty knife or trowel.
Be sure to press it firmly into the hole or crack and smooth out any excess material.
- Allow the plaster to dry completely before sanding it down with fine-grit sandpaper. This will help create a smooth surface that can be painted over later.

In conclusion, while Plaster of Paris and patching plaster are both made from gypsum rock, they are not the same thing.
