Repair the plaster and cover up flaking, holes and cracks

The repair of damage in the plastered window is possible with different aids such as acrylic filler or with identical plaster. Cracks and small holes can be well filled and concealed with ready-made fillers. In the case of larger holes and chipped corners, subsequent plastering including a primer is recommended.

Mending and repairing means the best possible concealment

If a wall with structural plaster is damaged, the optical adjustment of the repaired areas is the greatest challenge. If the structural plaster is then repainted, lamination is easier.

Since window plaster develops a structure from its properties when it is applied and processed, it can only be adapted as well as possible when repairing. A completely identical structural picture can hardly be implemented.

Repair in four steps

1. Flakes, holes and cracks must be cleaned of all crumbly, loose and sandy particles. After picking up all of the coarse crumbs and lumps, a powerful vacuum cleaner will help remove even the fine dust.

2. When cleaning, the edges and plaster edges must also be tested for durability. Loose plaster edges must either be broken out until the plaster that holds the plaster is exposed, or they must be fixed with filler.

3. As a rule of thumb, the width or the diameter of the flaking, hole or crack, the distance of up to three structural grooves in the plastered glass, should be repaired with filler from outside the material. Broader damage and diameter are sealed with fresh plaster.

4th. A filling compound such as acrylate is injected into the hollow space from a cartridge or tube. Mixed replacement plaster is "plastered" into the cavities after the previously applied deep primer (€ 4.81 at Amazon *) has dried. The freshly filled material is adapted to the surface of the surrounding structure with a wet brush.

Tips & Tricks If you are unsure which grit and type of plaster you would like to touch up, you can get a few fragments from a specialist company (painter, plasterer) to find out which plaster and which grit it is. The painter at the construction site will also be happy to provide you with information and, if necessary, a small amount of the required plaster for a small tip.
