Sikalastic® Rapid-721
Two component, fast-reactive, highly flexible PMMA based waterproofing resin
Sikalastic® Rapid-721 is a seamless, crack-bridging and joint-bridging waterproofing membrane that is able to withstand mechanical stresses. It
contains a highly flexible and fleece-reinforced waterproofing layer as well as abrasion-resistant system layers for foot traffic. The waterproofing system's liquid application and high bonding strength on almost any substrate also allow breakthroughs and upstands to be integrated securely and seamlessly.
- Cold applied
- Fast-curing
- Highly flexible and crack--bridging even at extreme sub-zero temperatures
- Permanently weather--resistant (UV, hydrolysis and alkali resistant)
- Fully bonded to the substrate, therefore no flow paths for water under the membrane
- Easy and fast application
- Can also be applied at sub-zero temperatures
- Solvent-free
- Seamless membrane
- Minimal disruption and low maintenance
- Elastic properties – tolerant of thermal movement
- Flexible, impact resistant membrane
