Part of the Watco Roofite range of products to repair, protect and waterproof roofs:

Watco Roofite Solar Reflective is a thick bitumen-based weatherproofer with aluminium flake added for extra solar reflective properties.

Surface Preparation

• Surfaces should preferably be as dry as possible - Emergency patch repairs can however be successfully completed to surfaces with running water
• Remove any loose material and dirt
• Very porous, dry surfaces should be primed with Watco Roofite/Roofite Solar Reflective diluted with 25% white spirit
• A wire brush should be used to remove all traces of moss etc.
• A fungicide may be required for heavily contaminated surfaces
• Specialist advice must be sought when dealing with old asbestos/cement roofs - please contact our Technical Department on 0113 2455450 (option 2) or send a message to [email protected] for details

Application

• The coating should be applied generously by brush at the rate of 1m² per kilo
• If a second coat is required it should be applied at right angles to the first coat
• Do not brush out to a thin film
• Cracks, splits, holes and leaks around roof sheet overlaps should be treated in the following manner:
  • Apply a generous coat of Watco Roofite and immediately bed in a strip of Watco Roofite Scrim cut to a suitable size
  • Apply a further coat of Watco Roofite over the scrim using a stippling action and leave to cure
  • Deep pits and cracks in flat concrete roofs etc can be filled with a mortar consisting of Watco Roofite mixed with Roofite Sand Additive
  • The surface should be primed first with Watco Roofite before trowelling in the Watco Roofite and additive mix
  • In exceptional temperature conditions advice should be obtained

Limitations

• Roofite/Roofite Solar Reflective are not suitable for coating bare wooden substrates in order to form a waterproofing seal
• Entrapped moisture on porous surfaces may cause blistering in warm weather or spalling at low temperatures.
• Only limited emergency patch repairs should therefore be made to porous surfaces while wet.
• Not suitable for use on EPDM rubber roofs.
• Check compatibility with other surfaces if in doubt.
• In common with all bitumen based products, black Roofite will gradually weather to grey colour
• For flat roofs which will be regularly walked on, please refer to Anti Slip Liquid Roof Membrane
