Rooflight Repair – GRP Rooflights

Problem: Surface Worn GRP

Surface Worn GRPProfiled translucent GRP rooflights are designed to provide diffused natural daylight with obvious benefits for commercial offices and buildings and are manufactured to meet stringent non fragile and fire retardant regulations.

The external weather surface is commonly protected with a UV resistant polyester film. Long term, it’s this film or gel coat and not the sheet itself that usually needs replacing. Caught in time, a rooflight can often be treated in situ and its protection preserved.


Treatment: Giromax Rooflight Repair

Giromax Rooflight Repair is a high performance, high build, single component moisture curing aliphatic polyurethane coating that cures to provide a clear, tough membrane principally for the re coating and sealing of aged and weathered GRP rooflights.
Delglaze Treated Surface

  • It is UV resistant and accommodates rooflight movement.
  • Primer-less adhesion to cleaned GRP surfaces.
  • Fast application without disruption to internal activities

Once clean of moss and lichen, Giromax Rooflight Repair seals in the exposed fibres, remaining flexible enough to accommodate rooflight movement. Fully cured, it provides a tough clear elastomeric coating with crack bridging capabilities that is particularly effective on difficult to replace rooflights on asbestos and fibre cement roofing. It is based on a unique blend of polyurethane resins to produce a coating, which provides a tough durable finish with a high degree of impact, erosion and weather resistant properties that is simple and easy to use straight from the tin by roller or brush application.
