It bonds to concrete, brick and metal and is ideal for permanently repairing and sealing openings, joints, cracks and fixtures in chimneys, piping, refractory elements and other areas which come into direct contact with flames or are exposed to extremely high temperatures (up to 1500°C).

ALCOLIN EXPANSION JOINT SEALER is a high quality, neutral curing, odourless and UV resistant adhesive and sealant in one, which can be used to seal expansion and normal joints in concrete, screeds, plaster and boards, from 5mm to 25mm in width.

ALCOLIN CHEMICAL ANCHOR is an epoxy-based, styrene-free, high performance, rapid curing, two part chemical anchoring system. It is designed as a fast curing, high strength fixing anchor for very high loads and critical fixings especially in corrosive environments and damp conditions.
