ndigo Dirtproof & Waterproof Exterior Laminate is specially formulated with groundbreaking nanotechnology to give an extremely smooth and dirt resistant finish, which will keep the walls looking new for a very long time. It is based on flexible acrylic emulsion fortified with Silicone polymer, thus giving high UV resistance with increased water repellancy. The paint film bridges micro cracks, and therefore prevents water ingress, providing waterproofing action. It is highly UV resistant, with very powerful anti-algal and anti-fungal properties. It is the only exterior emulsion to offer both dirtproof and waterproofing properties together.
