What Are the Plaster Materials Needed to Plaster a Wall?

Plaster provides a solid surface that allows you to repair damaged walls or to cover an entire wall before painting. Plaster is relatively inexpensive, and there is little experience needed to complete a project that will have a big impact on the appearance of your wall. Additionally, only a few key supplies will be needed for this do-it-yourself project.


A trowel helps level plaster onto your wall.

The most important material necessary to plaster a wall is the plaster itself. A variety of similar products are available on the market. Patching plaster is intended to be used to repair holes in the plaster, although plaster of Paris may also be used. A joint compound that sets is another option, and it consists of a powdery material that you mix with water. Whichever material you use, you must be sure to keep it covered when you are not using it to avoid drying the product out.


A trowel is a long rectangular tool that you use to apply the plaster to the wall. It has straight lines and is usually metal. It comes with a handle that you hold so that it is easier to work with. Dip the trowel into the plaster container, being sure that the majority of the plaster is on the center of the blade. Press firmly on the wall and move the trowel back and forth in an upward motion to make a smooth layer of plaster.


A hawk is an optional tool that you can use when plastering a wall that will make the job take a little less time to complete. It looks like a metal sheet and its basic purpose is to hold plaster in place so you can dip your trowel in it, similar to a painter's palette.


While a trowel is effective in spreading plaster over a large area, a small five-to-12--inch knife works well for small areas, such as repairing holes in the plaster. Use the knife to spread the plaster or compound around over a small area.


Water can be added to the plaster to make it easier to manipulate. A few drops of water mixed together with the plaster gives it a thinner consistency, which allows you to move it more easily across the walls and into nicks and crannies to repair the wall.

Preparation Materials

You will also need a few items to keep your floors clean and yourself safe. Lay down painter's sheets to protect your flooring from this messy project. Place a small ladder next to the wall when you must elevate yourself to reach the top of the wall.
