Applications
- Expansion joints on porous substrates and general interior/exterior sealing applications
- Construction joints around door and window frames
- Substrates may include concrete, brick, timber, metal, PVC components and structures
Advantages
- High elasticity and movement capability — accommodates ±25% to ±35% movement (depending on the specific grade such as Construction+), resisting thermal expansion and contraction stress and reducing cracking
- High weather resistance — excellent ageing and UV resistance, ideal for long-term outdoor exposure
- Convenient application — single-component, ready to use, good workability, low sag, and minimal bubbling during curing
- Paintable — can be overcoated with most conventional exterior coating systems once fully cured
