Application

Suitable for use in joints in sea walls, and in trafficked floor joints which require a fast cure.

Description

One part polyurethane sealant which cures, on exposure to moisture vapour, to form a firm, flexible rubber.


Features and benefits:

  • Non-biodegradable and abrasion-resistant.
  • Not recommended for joints in lightweight cladding, very heavily trafficked areas, or use against natural stone.
  • Anticipated service life in excess of 15 years.
  • Health and safety: Contains isocyanates; adequate ventilation is required; avoid contact with eyes and skin.
