Energy Star EC-100 Dirtguard SM

Energy Star EC-100 Dirtguard Silicone Modified is a water-based, second generation 100% acrylic waterproof membrane coating with high infrared heat reflectivity. Applied as a liquid, it forms a seamless waterproof membrane in situ on the substrate, offering excellent resistance to ponded water when fully adhered.


A Water-based, Second Generation
100% Acrylic Waterproof Membrane Coating
With High Infrared Heat Reflectivity.


The product is a semi-gloss, crack bridging elastomeric coating with excellent elongation and recovery characteristics, which provides a positive waterproof seal. It is silicone modified for added water resistance and durability.

Energy Star EC-100 Dirtguard Silicone Modified is a high solid, low V.O.C., second generation 100% acrylic with low temperature flexibility to -20°C and its' low odour formulation contains no harmful solvents, making it environmentally friendly and safe for applicators.
