Repair of non-active cracks on facades
The repair of static (stationary or slightly moving) cracks is most safely carried out with an ETICS (see also application tip: "Repair of cracked facades or joints with an ETICS"). If only the render must be renovated, the following steps must be followed. Depending on the type and extent of the cracks, it must be expected that even the new render will not remain crack-free.

7. In case of active cracks knock off the render in a width of 20 cm on both crack sides. Fix the glass-fiber joint mat weber.therm Glasfaser-Fugenmatte with the bonding and reinforcing mortar weber.therm 300. In case of larger movements within the substrate lay a corrugated paperboard for purpose of decoupling. Place a galvanised, welded wire mesh (for ex. Distanet) tension-free and apply weber.dur 132.
