Product Characteristics Ideally the CrysticROOF FR Topcoat and ambient temperature should be at, or above, 15 ºC before curing is carried out. Lower temperatures will lengthen the cure time considerably. Stir well by hand, or with a low shear mixer to avoid aeration, and then allow to stand to regain thixotropy.

CrysticROOF FR Topcoat requires only the addition of a catalyst to start the curing reaction. The recommended catalyst is Catalyst M (or Butanox M50), which should be added at 2 % into the gelcoat. (Please consult our Technical Service Department if other catalysts are to be used). The catalyst should be thoroughly incorporated into the topcoat, with a low shear mechanical stirrer where possible, for normal use, the application of CrysticROOF FR Topcoat should be controlled to 0.4 – 0.5 mm (0.015 – 0.020 inch) wet film thickness, As a guide, approximately 650-800 g/m 2 of topcoat mixture (depending on pigment) will give the required thickness when evenly applied. CrysticROOF Topcoat should be applied to clean and dry surfaces and when used outside when rain is not likely to fall within 2 hours of application.

CrysticROOF® will be leak-free for a minimum of 10 years when using 450g CSM (or 15 years if using a 600g CSM chop strand mat) if installed under the right conditions following the recommended procedures by an experienced contractor. These details are contained within this guide and in the materials datasheets. Like any materials exposed to the elements, UV light degradation may cause the topcoat colour to change. This will not cause the roof to leak or affect the integrity of the roof. Please ask for details if there is a requirement for a GRP roof system. If a longer guarantee is required then CrysticROOF® BBA Premier can be used to give a 20 and 25 year guarantee.
