SunShield is an environmentally friendly, hydrophobic, colour-fast roof coating based on a pure acrylic emulsion. It dries to a flexible, UV -, mould – and fungal resistant, low sheen film. SunShield’s heat reflective technology will not only decrease substrate – and interior temperature, but also protect dry film to allow for a longer-lasting beautiful appearance.
This product has been formulated to improve on the TSR (total solar reflectance) compared to Nexus Roof. Depending on colour, SunShield’s total TSR is minimum 30%. The exact cooling-effect or reduction of temperature is depended on a number of factors ie.substrate, insulation, shading, humidity, region, etc. In comparison to Roof, SunShield will have a heat reduction on substrate of approximately 15%, this translate into 5-15°C and 2-10°C on the interior of a building. White with the highest TSR will have the best result on reduction of energy levels. It is recommended to paint White over stable, darker shades colours before the application of SunShield. This will improve the total TSR.
All surfaces must be clean, sound and dry.
Remove all loose flakes and apply WallPrime, to obtain a stable surface.
Even-out imperfections with WallSkim and fill cracks with WallFill.
To stabilize chalky surfaces, apply WallPrime.
Previously painted sound surfaces can be washed with sugar soap and rinse thoroughly with clean water.
To ease application, sand previously painted stable surfaces.
For water damaged, porous and alkaline surfaces, Apply WallPrime, to stabilize surface.
Remove rust on mild steel and galvanize. Apply HydroEtch/AllPrime, to stabilize surface. If rust cannot be removed completely, spot prime with a rust converter before application of primer.
Before recoating, sand previously varnished surfaces well to remove mirror-like image to a flat film.
