weber.dur 121 SLK
Product formerly named: maxit ip 14 L SLK
weber.dur 121 SLK
Mineral lime-cement render for facade socket parts on heat-insulating masonry, with optimized setting and scratching properties
Product features
- weather- and frost-resistant
- water-repellent
- resistant to mechanical loads
- regular and quick-setting behaviour on almost all surfaces, allowing scratching works with grid float after only approx. 2 hours
Product advantages
- highly water-repellent
- highly impact-resistant
- shorter and uniform setting time
weber.dur 121 SLK is used inside and outside on masonry, in socket parts and especially on thermally insulating masonries (according to DIN 1053). Ceramic wall tiles and slabs can be applied onto weber.dur 121 SLK.
