Excellent adhesion to common construction substrates—including concrete, masonry, aluminum, steel, and painted surfaces—without primer.
Low modulus formulation provides high movement capability (±25% joint movement) while maintaining long-term durability.
Non-sag rheology enables vertical and overhead application with minimal tooling effort.
Paintable with water-based and solvent-based paints after full cure (typically 7 days).
Low VOC content compliant with major regional environmental regulations including LEED and GreenGuard.
Expansion and control joints in precast concrete façades.
Perimeter sealing of windows, curtain walls, and cladding systems.
Sealing of structural glazing perimeter bonds where moderate movement is expected.
Interior and exterior architectural trim and panel joints.
Renovation and retrofit projects requiring primerless adhesion to aged substrates.
