Nanotechnology based Nano Crack Filler is complete cement based polymer modified powder material for filling cracks in plastered surface, that is highly stretchable, durable, water repellent, crack resistant, UV resistant, fungus/ algae/ bacteria resistant, and thermal insulating. One of its major benefits includes its ability for outstanding adhesion. By virtue of which it gets embedded in the surface, makes surfaces smooth & impact resistant. It provides resistance against water and is anti-bacterial in nature. Nano-materials have been used for smooth application & high coverage. Being oil-free (dry/wet) in nature, release of oil due to dampness and peel-off of paint on the surface is unlikely to happen. It contains flexible Nano-materials, that resist crack formation and hence this product can be used as an excellent crack filler material. The VOC for this material is zero.
