Basic Facts You Need to Know When Fixing Plaster Damage


Cracks in plaster walls are among the most common problems that homeowners face. While gaps in drywall or plaster can be caused by several things, such as settlement or poor craftsmanship, they are usually not a structural issue and can be easily repaired.

Although cracks can occur for various reasons, they are typically caused by changes in temperature or humidity. These changes can cause the material to expand or contract, which can stress the material and cause it to crack. External forces, such as impact or vibration, can also cause cracks.

Depending on the severity of the crack, there are different methods to repair cracks in plaster walls. For small cracks, using a putty knife or caulk to fill the damage and then painting over it is usually sufficient. For larger cracks, it may be necessary to use a patching compound to fill the gap and then sand and paint over it.

If you are unsure how to repair cracks in plaster walls, several resources are available; you should pay close attention to this article. We have tapped the expertise of leaders of the plastering service in Brisbane to share their knowledge. 

What Is Plaster Filler?

If you ask a contractor specializing in plastering services for the primary material for this project, they will probably respond with plaster filler or Polyfilla. It is a specialized plaster used to fill in cracks, holes, and other imperfections in walls and ceilings. 

Unlike traditional plaster, which is applied in a thin layer, Polyfilla is a thick, viscous material that can be spread over a wide area. It is typically made from gypsum, sand, and water and can be purchased at most hardware stores.

It is most commonly used to repair cracks in walls and ceilings, but it can also fill holes in woodwork or level out uneven surfaces. Plaster filler is easy to apply and can be sanded down to create a smooth, finished surface.

Should I Use Plaster or Plaster Filler?

There are several reasons why plaster filler is a better option than plaster for filling in cracks:

  1. It can be easier to control when working in a small area.
  2. It is easier to apply and smooth out.
  3. It is less likely to crack or chip when dry.

When working with plaster, it is necessary to have a good understanding of how it works. Plaster is a material applied wet and then dries to a hard, solid state. It is made up of a mixture of lime, sand, water, and other ingredients.

When working with plaster filler, you do not have to worry about it drying out too quickly. You can take your time applying it and smoothing it out. And if it does dry out too quickly, you can add more water.

Another advantage of plaster filler is that it is less likely to crack or chip when dried. Plaster can sometimes crack or chip when it dries, but plaster filler is much less likely to do so. Plaster filler is a brilliant option if you want a material to fill in cracks. It is easy to use, easy to control, and less likely to crack or chip.
