Sikalastic® Rapid-721 Thixo

Two component, fast-reactive, highly flexible PMMA based waterproofing resin for use on details

Sikalastic® Rapid-721 Thixo 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
