Product Features
✔ Extremely high strength: Cures to a very hard finish — reportedly up to five times harder than concrete — which makes it suitable for tough exterior repairs that need durability and load‑bearing capacity.
✔ Waterproof and weather‑resistant: Once fully set it resists water ingress and general exterior conditions, helping maintain performance in damp or exposed locations.
✔ Rapid setting: Begins to firm quickly, often becoming touch dry within a couple of hours and hard enough to sand and paint within the day.
