WhiteCAPS from SWT Group is a water based, modified acrylic white reflective roof coating. It has been uniquely formulated for application to granular roofing membranes to enhance the reflectivity, performance and extend the life of the roof at very low film thickness (4-5 mils). In addition to providing blinding initial reflectance measurements of over 75% for California Title 24 “Cool Roof” qualification, WhiteCAPS also enhances the adhesion of granules to the membranes and provides added abrasion, impact and UV resistance to greatly extend the life of any roof. It has excellent stain resistance and bleed blocking properties while remaining flexible enough to expand and shrink with the membrane across all seasons.

Applications & Uses

Application Method
Applications

WhiteCAPS can be roller or spray applied using various application equipment including conventional, HVLP, airless or air-assist airless spray equipment. Make sure surface is clean, dry and free of loose or unbonded substrate. Stir thoroughly before use. Two coats for a total dry film thickness of 8-10 mil is recommended. Each gallon should cover 100-150 sq ft depending on granularity and condition of substrate. Wait 3-4 hours between coats.
