Sika Pro-3 Purform, Concrete Grey, box of 20 foils

Sikaflex® PRO‑3 Purform® is a premium, one-part polyurethane sealant engineered specifically for floor joints and civil engineering structures. Built on advanced Purform® technology, it offers an ultra-low monomer content (less than 0.1%), ensuring it meets the highest health and safety standards without the need for additional REACH safety training.

Supplied in trade-standard 600ml foil sausages, this high-performance mastic is designed to withstand heavy traffic, harsh chemicals, and constant water immersion. It is the go-to choice for expansion and connection joints in demanding environments, providing a permanent, elastic seal with exceptional adhesion to concrete, stone, and metal.
