TRUBUILD WPC 666 is a single-component, acrylic-based elastomeric waterproof exterior coating developed to protect external building surfaces against water ingress, rain exposure, seepage, dampness, and weathering effects. Once applied and cured, it forms a thick, seamless, UV-resistant protective membrane that improves exterior durability while maintaining flexibility to accommodate minor substrate movement.

This coating is designed primarily for external walls, facades, terraces (non-traffic areas), corrugated sheets, stone walls, asbestos sheets, and sloped roofs. Its elastomeric nature delivers significantly higher elongation compared with conventional paints, helping reduce hairline cracking and moisture penetration over time.

One of the major customer advantages is the self-priming capability, where controlled dilution for primer application helps seal substrate pores and optimize coating consumption before applying undiluted finish coats. The coating also supports tinting into multiple shades, combining waterproof performance with decorative appearance
