Before getting started here are a few best practices to keep in mind when hanging pictures on plaster walls. First, avoid using plaster nails because they cause cracking.

Lastly, whenever you drill into the wall, place a piece of painters tape or masking tape on the wall in order to keep everything intact.


What is a plaster wall made of?

Up until the 1940's, the interior wall of choice, was plaster wall. Layered strips of wood, called lath, were placed on top of each other in order to create a thick and sturdy wall. Supporting this lath, is a wooden frame called a wall stud. Nails are used to hold the wooden lath and studs together. In order create a wall with a nice finish, several layers of plaster are coated on top.

In a nutshell, a plaster wall is made up of lath attached to wall studs and covered in plaster. Modern homes eventually switched to using drywall panels instead. This was mainly due to the fact that they are easier to install and less brittle. However, plaster-wall is making a comeback in some circles.

The advantages of plaster wall vs. drywall

Plaster wall has a few great qualities. First of all, it often has a rugged and uneven surface which provides a stylish, old-home look. Drywall on the other hand, is flat and smooth and doesn't have a whole lot of character.

Secondly, plaster wall is thicker than drywall which provides a much needed level of sound-proofing. Lastly, plaster wall is more contour friendly and allows home builders to create curves around the ceiling and the edge of the wall. One of plaster wall's downsides, however, is that it's more brittle than drywall and it can break a lot easier.

How to find a wall stud

To locate a wall stud, you'll need to use a magnetic stud finder. Stud finders work by detecting the metal nails that are in the wall studs. Once you've located a stud, you can simply measure 16 inches (the standard spacing of studs) on either side to locate the other studs.

You can use long wooden plaster screw to hang a picture in a wall stud. It is highly recommended to drill a hole first, because this will greatly reduce the risk of the plaster cracking. Another best practise is to place a piece of masking tape on the area that you will be drilling into.
