weber.therm 370
Product formerly named: maxit multi 275
weber.therm 370
High-performance mineral bonding mortar for critical substrates
Product advantages
- high bonding strength
- flexibilized
- long-term and frost-resistant bonding
weber.therm 370 is a hydraulically setting, highly modified bonding mortar. It can be used for bonding to very low-porosity substrates, such as bituminous waterproofing layers or dense concrete. Additionally, it is suitable for bonding ceramic coverings onto the ETICS (external thermal composite systems) weber.therm AK 500/BK 500.
