Specification for solar reflective water-based coatings


This standard applies to a ready-for-use, solar reflective water-based coating on cementitious façade. All facades, new or previously painted, are prepared according to the paint manufacturer’s recommendation. The test methods for the quality and performance of the coatings are also covered in this standard.

This standard specifies the requirements of solar reflective coatings that are formulated with environmentally-friendly materials containing low hazardous substances and low volatile organic compound (VOC) levels. Such materials help reduce chemical emissions during application, are chemically non-toxic in nature and are environmentally non-polluting at any stage of the product lifecycle.

This standard does not cover roofs, pavements, metallic substrates applications, elastomeric coatings for waterproofing or other exterior cladding. Facades are walls with slope angles of more than 70°.
