⚡ At a Glance
- • Elasticity: Highly elastic compound resists cracking while accommodating surface movement
- • Best for: DIYers and tradespeople repairing cracks in walls, floors, patios and driveways
- • Not ideal for: Major structural or load-bearing repairs that require engineering-grade materials
Flexible, weatherproof sealant cures quickly for fast turnaround on repairs. Bonds to masonry and timber while keeping joints resilient through temperature changes.
Flexible, durable repairs – thanks to highly elastic formulation
A flexible polymer and silicone-based composition allows the sealant to stretch and rebound as surfaces expand and contract. The elastic matrix maintains adhesion under pressure shifts without splitting.
Durable gap filling that stays intact through seasonal movement, reducing repeat repairs. Ideal for cracks that open and close with temperature changes.
Weatherproof protection – with water, heat and freeze resistance
Weatherproof compounds in the formula resist moisture ingress, UV exposure and freeze-thaw cycles, preventing the seal from crumbling. The waterproof silicone element keeps joints sealed under heavy rain and sunlight.
Seals exposed joints reliably, protecting foundations, patios and external walls from moisture damage. Suitable for use in climates with wet winters and hot summers.
Faster project completion – thanks to quick-drying cure
The quick-drying chemistry reduces tack and cures to a stable finish within hours rather than days, allowing subsequent painting or sealing steps to proceed sooner. The material also self-levels for an even finish.
Shorter wait times between application and finishing cuts labour and disruption. Useful for emergency fixes and jobs where downtime must be minimised.
