RCM ElastiClear Waterproofing Coating

RCM ElastiClear Waterproofing Coating is a versatile, water-based, multi-purpose waterproofing system designed to protect and preserve most building surfaces—without changing their appearance.

Formulated with pure acrylic co-polymer technology, this almost clear, UV-resistant coating offers long-lasting waterproofing, corrosion protection, and encapsulation for a wide range of surfaces. Its high flexibility and superior adhesion make it ideal for demanding environments, including roofs, walls, metal structures, and more.

It’s safe for potable water harvesting, eco-friendly, and low in odour, making it ideal for both residential and industrial applications.
