Watco Solar Reflective Coating is enhanced with fine glass microspheres to maximise solar reflection and surface cooling. Testing has shown that it reflects 89% of infra red radiation and 94% of visible light. Total Solar Reflectance (TSR) value = 88% (copies of the test certificate are available on request).
It is capable of withstanding up to 10 years or more of extreme weather and temperature changes. For areas with regular foot traffic please see Watco Balcony Coating System.

- Preparation & Application
All surfaces should be clean and free of loose material and contamination. Remove all moss, lichen, fungal growth and other contaminants. Scrape off any loose paint. Surfaces can be slightly damp but they should not be wet. Priming is not necessary.
Asbestos/cement roofs can be successfully coated, but may require special preparation to comply with asbestos regulations. All surfaces must be clean and free from loose and dusty matter. Previous coatings should be sound and well bonded.
Brick, masonry, stone, render and other cementitious surfaces
Surfaces should be clean, dry and free of any loose material and contamination. Use a fungicide if necessary to remove any fungi, mildew or moss, etc. Scrape off any loose paint. Existing hard smooth, glossy paint should be lightly sanded to provide a key. Wash with a detergent solution, rinse with water and allow to dry. Make good any minor defects with external filler or a sand/cement mix. Damp down dry, absorbent surfaces with water to leave them slightly damp, but not saturated or wet.
All bare wooden surfaces should be clean and dry. Not recommended for door or window frames. Do not apply to previously painted wood unless all traces of old paint have been removed.
Application If appearance is critical we recommend the application of a small trial area first.
Do not stir, but blend in any thin liquid that may have appeared on the surface of the product. Apply by brush or roller, leaving the first coat to become touch dry (about 4 hours) before applying the second.
