Over time, under the influence of various factors, the plaster used to decorate walls and ceilings can crack, peel, or suffer other damage. This not only spoils the appearance but can also lead to more serious problems, such as moisture penetration and surface destruction. In such cases, it is better not to delay but to start the process of restoring the plaster as soon as possible to prevent further deterioration of the walls and the need for more extensive repairs. The first step is to determine the exact cause of the damage to choose the best way to fix the defect. Correct and timely plaster repair will help maintain the aesthetics and durability of the coating for many years.

Why does the plaster crack or suffer other damage?

The causes of plaster damage can vary from natural wear and tear to mechanical stress, building shrinkage, or improper application. In any case, it is important to repair the defects in a timely manner to prevent them from worsening.
The process of restoring plaster includes several stages: preparing the wall, applying a new layer of material, and finishing work. PlasterX specialists can advise you on the possibility of repairing the coating yourself. They will also provide recommendations on the choice of materials, tools for work, and technology for applying mixtures to ensure durability and high quality of the coating.

How to fix the plaster?

There are several main stages of repair:

1. Assessment of the surface condition – before starting work, you need to determine the extent of the damage. If the problem is localized, you can repair the plaster yourself. However, if a large area is damaged, you may need to completely replace the damaged layer of material.
2. Preparation of the wall – includes cleaning the surface, removing peeling plaster, expanding cracks to fill them properly, and applying a primer.
3. Applying a new layer – drywall or special plaster mixes are used, which are evenly distributed over the damaged area.
4. Sanding and finishing work – after the material has dried, you need to putty the wall with plaster, sand the surface, and, if necessary, apply a decorative coating or paint.

PlasterX experts can help you determine how to repair plaster walls and which materials will be best for your case. If you decide to do the plaster repair yourself, you should carefully select the mixtures and follow the application technology to get a long-lasting result.

Tools and materials needed to repair the plaster coating yourself

Before you start repairing the plaster, you need to prepare all the necessary tools and materials:

• A spatula (wide and narrow)
• Plaster grater
• Construction mixer or drill with a nozzle
• A container for mixing the solution
• Masking tape
• Primer
• Plaster mixture (according to the type of wall)
• Reinforcement mesh (for large cracks)
• Sandpaper – medium grit for initial smoothing and fine grit for finishing touches
• Protective goggles and gloves

If you need to fix a plasterboard wall after serious damage, you will additionally need reinforcing tapes or special patches.

The availability of all the necessary materials and their proper selection will greatly simplify the process of restoring the plaster and ensure a high-quality result.

Preparing the walls for repair

Preparing the walls is a key stage that determines the quality and durability of the plaster repair:

• Remove old and peeling plaster, dust, dirt, and other contaminants.
• Use a trowel to widen the cracks to ensure better penetration of the plaster mixture.
• For large cracks, use a reinforcing mesh. Attach it to the wall with glue or dowels.
• Apply a primer to the entire surface of the wall. This will improve the adhesion of the plaster mixture and prevent it from cracking.

It is important to carefully inspect the wall to identify all damage, even the smallest. It is necessary to remove all remnants of the old plaster that may peel off in the future to ensure strong adhesion of the new layer. If there are traces of fungus or mould on the wall, they must be treated with a special antiseptic solution before priming.

The process of applying plaster

After preparing the wall, you can start applying the plaster mixture:

• Mixing the mortar – prepare the plaster mixture according to the instructions on the package. Use a construction mixer or a drill with a nozzle to obtain a uniform consistency.
• Apply the first layer – use a wide trowel. Spread the mortar evenly over the wall surface.
• Wait until the first layer is completely dry before applying the next one.
• Apply a finishing coat of plaster to achieve a smooth surface. Level the surface with sandpaper.
• Use a corner trowel to level the corners.

If you are not confident in your abilities or are faced with a difficult case, for example, when repairing a plasterboard wall or restoring plaster on historic buildings, it is better to contact professionals. PlasterX specialists have many years of experience working with different types of plaster and guarantee a high-quality result. They will help you not only repair the damage but also choose the best materials and technologies for your specific case.

Plaster restoration – finishing work

After the finishing layer of plaster has dried, it is necessary to perform the final work:

1. Using fine-grit sandpaper, sand the surface to achieve a perfect smoothness.
2. Remove dust and residual materials from the surface.
3. Apply paint or another decorative coating according to your preferences.
