Application

Flat roofs. Excellent adhesion to most substrates.

Description

Langley PU is a high-performance, cold-applied, low-odour, single pack, elastomeric, high-build polyurethane coating. It cures to form a seamless, durable, long-lasting, waterproof membrane for all types of roof applications. The system comprises two moisture-triggered polyurethane layers, incorporating a random weave glass fibre mat (GFM). The Langley GFM breaks down into individual fibres when embedded in Langley PU Embedment Coat enabling complex details to be encapsulated. The system is completed by applying Langley PU Topcoat, providing a durable and waterproof membrane.


Features and benefits:

  • Single component.
  • Low odour.
  • Cold applied.
  • Tough, long-life membranes, glass fibre reinforced.
  • 25 guarantee.
  • Easy to apply by roller, brush or airless spray.

Reinforcement

Langley GFM 225.

Guidance for specification option:

Langley PU GFM Reinforcement is a random weave chopped strand glass fibre mat. It is used as a full reinforcement on heavy-duty flat roof applications, where ponding is evident, and as localised or partial reinforcement in other areas. It helps to provide the ideal solution for areas subject to movement and damage, especially around vulnerable areas such as upstands, joints etc.
