Over the years, heat, cold and moisture can damage a solid garden wall to such an extent that cracks appear in the masonry. In our guide article, we explain how you can easily and professionally repair the unsightly damaged areas yourself.

Cracks in the garden wall should be repaired as soon as possible

What consequential damage can occur as a result of the cracks?

Moisture can penetrate the masonry through the cracks and cause serious damage. The reason: when there is frost, the water freezes and expands. There is also a risk of salinity in the masonry and the formation of mold. As a result, the building fabric suffers and the wall loses stability.

Eliminate minor cracks

You can fill these relatively easily with ready-to-use filler:

  • First clean the affected area of the garden wall from dirt and loose parts.
  • Wet the areas that need repairing well, since the fillers are mostly water-bound.
  • You can then fill the cracks with putty.
  • Cracks that are deeper and wider than two millimeters should be filled in two or more work steps. Allow the material to dry thoroughly in between.

Repair larger cracks

The classic method of filling larger cracks in the garden wall is plastering. For this purpose, the damaged areas must first be carefully enlarged, for example with an angle grinder or a hammer and chisel. Lay out the cracks in a V-shape, this gives the edges a larger adhesive surface.

Paint the cracks with deep primer and then fill them in with repair compound. Two to three layers may be necessary for this. In the case of very large cracks, it is advisable to insert a strip of reinforcement fabric. This strengthens the plaster and thus ensures greater stability of the material.

tips

Since garden walls are permanently exposed to weather conditions, it is advisable to seal cracks as soon as possible. This ensures that the damage does not go too deep into the masonry and that costly repair work is not required.
