Simple & safe to the goal

  1. Application

    1. Spray/apply the lime-cement render weber.dur 100 full-surface. Observe a waiting time of 4 weeks.



    2. Apply a lightweight render, for ex. weber.dur 132 on the substrate. After a waiting time of at least 14 days, apply a reinforcement layer, like the bonding and reinforcing mortar weber.therm 300 and the woven mesh weber.therm 310.
