Plaster has been used for centuries to cover walls. It wasn’t until the 1940s that it was replaced by drywall. Depending on how you look at it, plastered walls can be beautiful and troublesome. Plastered walls are applied by highly skilled workers using a trowel or hawk. It could take a month or longer for a plastered wall to cure.

It’s crucial to understand what a plaster wall is and its pros and cons.

The Pros

If you’re deciding to replace your plastered wall anytime soon, most homeowners hold on to these benefits:


One of the most important benefits of a thicker well is energy efficiency. A traditional plaster wall that is about ⅞” thick is almost twice as thick as drywall applications. A thicker plaster wall provides better thermal breaks compared to drywall. Which means you will save money on utilities.

Excellent Sound Blocking

Since plaster is thicker and harder than drywall, it has better sound attenuation. Plastered walls increase privacy because of their excellent sound blocking feature.


A plaster wall’s tensile strength is significantly better than drywall. For instance, you can even try punching a hole in a plaster wall. You’ll be amazed that it won’t happen. The strength of the plaster wall can prevent dents, dings, and nicks that usually come with drywall.

The Cons

Although plastered walls are great, they still have drawbacks. Here are some of the cons of a plastered wall:

Can Crack Over Time

As years go by, plaster walls are curing harder than ever. This causes it to become brittle and eventually crack. Cracks are common in areas with heavy food and weight traffic as well as unstable foundations. Gravity also affects the plaster ceiling and heavy foot traffic from upstairs can cause the plaster ceiling to weaken and eventually crack.

Poor WiFi Signals

The downside of having plastered walls is WiFi signals are usually poor and you get no cellular signal at all. The solution is to upgrade to a mesh system that gets an adequate signal in a plastered wall home.

It Will Be Hard to Hang Stuff

Since plastered walls are very strong, it can be difficult to nail or drill into them—making decorating nearly impossible. However, there are some tricks in helping you hang stuff on a plastered wall that you can learn. The first rule in hanging things on a plaster wall is to avoid using a hammer. This can knock it loose and begins to sag then eventually falls off.


Having a plastered wall is worth it and offers so much more benefits. Although, there may be some disadvantages such as a poor WiFi signal. However, there is a modern-day solution to that issue. Nowadays, plastered walls are found in high end homeless due to the cost and skills it takes in having one.
