What's the difference between plaster and drywall.

Choosing between plaster and drywall is a decision that every homeowner should make before starting an indoor renovation project. Both materials have strengths and weaknesses and come in different price ranges. Before making a decision, make sure to understand what is the difference between the two materials and consider their pros and cons.

What is the difference between drywall and plaster


Plastering is one of the oldest building techniques. Plaster is made of lime or gypsum. It’s a white material which hardens when drying and it’s mostly used for covering ceilings and walls. Plaster is used as a protective cover over stone and brick masonry, but it can also be used for creating finish looks.

Plaster is a powdered mixture that you’ll need to mix with water to create a paste before applying on the walls. You’ll need to apply two coats of plaster to ensure full coverage. Stucco is a type of cement plaster that can be used on exterior walls. It’s made of sand, water, binding material (lime or gypsum) and cement.

Plaster pros:

  • Plaster is a hard material that creates a durable surface that can be painted over
  • Plaster can last a long time
  • The surface does not crack
  • Mixes up easily with water and it spreads evenly
  • Plaster is mould resistant
  • Plaster can be cleaned
  • Thicker plaster is a great sound proofer

Plaster cons:

  • Plaster is porous and absorbs moisture easily. That means that painting over it can be hard to do. You’ll definitely need more than two coats of paint to achieve the desired look.
  • Plaster cracks easily
  • Repairing plaster is expensive and hard. In most cases, you’ll need to remove a large portion of the material from the wall.
  • It’s hard to hang frames and shelving on plaster
  • The material is not suitable for exterior projects
  • Generally more expensive to install than drywall


Drywall, also known as plasterboard is made of gypsum mixed with water and spread between two large sheets of paper. Drywall is used for the construction of interior walls and ceilings. Plasterboard is installed by lifting the pieces and attaching them to wall studs. Drywall is available in two thicknesses – 9.5mm and 12.5mm. The front side of the drywall is usually white, so you can paint it over. Drywall can be noise and humidity resistant.

Drywall pros:

  • Drywall can be painted over
  • It doesn’t require sanding
  • Drywall is more stable than plaster
  • The surface is easier to repair
  • Drywall is fire-resistant
  • Provide sound and temperature insulation
  • Variety of sizes and types to choose from
  • Less expensive to install
  • You can hang shelving and frames on drywall

Drywall cons:

  • Installation process is more complicated. You’ll need to measure the space and cut enough pieces to cover the walls and install them on the wall studs.
  • Creates a mess during the installation
  • Drywall weights, so you’ll need a partner to help you with the installation
  • Drywall is not as flexible as plaster so it can be difficult to bend it to achieve the desired result.
  • Lower durability than plaster
  • If not installed correctly, the joints between the sheets are visible
  • Drywall is not water and moisture resistant, so it can’t be installed in bathrooms

What’s veneer plaster?

Veneer plaster offers the look and durability of the plaster and the strength of drywall. Plaster veneer is a technique for surfacing interior walls. The base is a gypsum board with moisture and adhering qualities (similar to drywall). After installing the board, one or two layers of plaster are applied.

Veneer plaster pros:

  • Veneer plaster is moisture resistant. It can be used even in bathrooms and laundry rooms.
  • Veneer plaster is strong and durable
  • There is no sanding required to achieve the desired finished look
  • You can hang heavy objects on
  • Veneer plaster can last for a long time

Veneer plaster cons:

  • Plaster veneer is way more expensive than plaster or drywall, simply because you’ll need more materials for the installation process.
  • Complicated installation process
  • It’s hard to find professionals competent to do the job
  • Longer installation process
  • Each coat of plaster should cure at least 24 hours before you can paint over it

Cost differences between plaster and drywall

Drywall is way cheaper than plaster, including materials, labour and installation process. That’s one of the reasons why drywall is the most preferred option. Drywall is perfect for the common areas in your home.

Veneer plaster is the most effective wall finish, but it comes at a much higher cost. You’ll need more materials, and at least two coats of plaster as a finish, which means that the cost for finishing one room can be almost the same as if you use drywall on three of your rooms.

Knowing the advantages and the disadvantages of plaster and drywall will help you make an informed decision before starting with your renovation project.

I had no idea that veneer plaster is actually more moisture resistant and can be used in bathrooms. I’m interested to learn if this plaster would also be ideal in areas where it can be pretty humid outside.

I am all into plastering as it is more durable and strong compared to drywall. But it can be complicated as opposed to the drywall. As a handyman, this article is greatly written for normal homeowners to generalize and choose what’s going to be best for them.
