Suitable substrate
The lightweight lime-cement fiber-reinforced underlay render weber.dur 137 or the bonding and reinforcing mortar weber.therm 300 must be roughened horizontally with a notched trowel, a comb or a hard broom.
-
2. Spray/apply the mineral coarse-graded scratch top render weber.top 204 AquaBalance and strike off to grain thickness in a thickness of 10 - 15 mm.
-
Corner design with edge protection angle
1. The edge protection angle is fixed with the profile bonding and installation mortar weber.mix 125 on the masonry. Respect the specific render thickness. The masonry is subsequently covered with an underlay render, e.g. weber.dur 132.

Corner design without edge protection angle
