Blackfriar Solar Reflective Paint – Reduce Roof Heat with Reflective Coating

Blackfriar Solar Reflective Paint is specially formulated to reflect sunlight and dissipate heat from dark-coloured roofs. Suitable for stable felt, bitumen, metal, concrete, brick, and more, the paint comes in two finishes: aluminium (bitumen-based) for weathered roof membranes and white (water-based) for new roofs.

Key Features:

• Reflects sunlight and reduces roof heat

• White finish resists surface fungal growth

• Self-priming 2-coat system

• Suitable for various roof surfaces including felt, bitumen, metal, concrete, and brick

• Outdoor use

• Water-based formulation (white) and bitumen-based (aluminium)

Application Information:

• Coverage: White – 4.8 m²/L per coat, Aluminium – 1 m²/L per coat

• Hard Dry: White – 2–4 hours at 20°C, Aluminium – 16–24 hours at 20°C#

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 Blackfriar Professional Solar Reflective Paint Aluminium diluted with 25% white spirit. A wire brush should be used to remove all traces of moss etc. A fungicide like Blackfriar Anti-Mould Solution or Concentrated Fungicidal Wash may be required for heavily contaminated surfaces. Specialist advice must be sought when dealing with old asbestos/cement roofs.

Technical Data

• Textured finish.
• Exterior use.
• Bitumen based.
• Fibre reinforced
• Contains reflective aluminium.

Coverage Rate
1m2/litre per coat. Two coats recommended. Roof overlaps and cracks, splits and holes will require a heavier application ideally with the use of scrim.

Drying Time
16-24hrs @20°C. Allow to dry for a minimum of 24hrs
@20°C between coats. Full cure is achieved in 5-7 days
@20°C. Note curing will only commence once any surface water has evaporated.

Directions for Use

Blackfriar Professional Solar Reflective Paint Aluminium should be applied generously by brush at the rate of 1m2/L per coat. 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 Blackfriar Professional Solar Reflective Paint Aluminium and immediately bed in a strip of scrim cut to a suitable size. Apply a further coat of Blackfriar Professional Solar Reflective Paint Aluminium over the scrim using a stippling action and leave to cure. Deep pits and cracks in flat concrete roofs should be filled prior to coating. Blackfriar Professional Solar Reflective Paint Aluminium is 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.
