Plaster facades with cracks are not just visually disturbing. Furthermore, cracks can cause serious damage to the façade, resulting in a decrease in property value. In addition to the surface of the building envelope, moisture entering through cracks creates a perfect environment for mould and algae to grow. You can moisten and then fill cracks in order to eliminate them. In order to prevent the crack from recurring, long-term protection should be applied to the affected areas.
