PRODUCT DESCRIPTION

Sikalastic®-590 is a premium one-component polyurethane modified acrylic liquid-applied waterproofing membrane designed to provide durable, seamless, and long-lasting waterproof protection for roofs and exposed building surfaces. It combines excellent UV resistance, crack-bridging performance, and improved resistance to limited ponding water, making it an ideal solution for both new construction and roof refurbishment projects.

Ready to use straight from the pail, Sikalastic®-590 can be applied by brush, roller, or airless spray, creating a seamless waterproof membrane without joints. The highly elastic coating adheres well to both porous and non-porous substrates, protecting concrete roofs, metal roofs, balconies, terraces, gutters, and complex roof details against rain, UV exposure, and weathering. Its water-based, low-VOC formulation makes it environmentally friendly and suitable for residential, commercial, and industrial applications.

Available in Grey and White, the white version helps improve energy efficiency by reflecting sunlight and reducing roof surface temperatures, making it an excellent waterproofing solution for Malaysia's tropical climate.
