Product Description
EXCEL Nanoseal is a water repellent nano coating with 45% to 50% active nano particles. The unique superior formulation based on metal oxides, used for imparting a colorless water repellent surface finish to porous mineral / construction material / stone surfaces without significantly reducing water vapor permeability. EXCEL NanoSeal forms an excellent weather coat for all types of cement and stone surfaces. It provides water repellence and leak proof coating within 8 hours of application. The water repellence further improves over 48 hours after application.
EXCEL NanoSeal by its name indicates a Super Hydrophobic, water repellent nano coating. Unlike various film of coating, EXCEL NanoSeal does not seal the pores at the surface of concrete. Instead, it penetrates into the pores and forms a very thin (nano) layer on the pore walls. These pores no longer will be wetted by water and the capillary uptake of water is prevented upto 90%.
On the surface treated with EXCEL NanoSeal, the drop of water is repelled and stands in the form of bead and does not penetrate inside. The size of EXCEL NanoSeal is 4 – 6 nm (0.005 micron) Whereas the pores on the mineral surface may vary from 5 – 200 nm. When the building materials come into contact with water, they absorb an amount of water which depends upon the porosity, resulting in penetration of water through the wall, cracks caused by swelling and shrinkage, destruction of concrete caused by corrosion of reinforced steel, lime leaching, chemical corrosion, binder transformation, etc.,
Conventional water repellents give only a short-term protection by forming a surface film. Long term protection is possible only by Nano sized water repellent, which penetrates up to 4-5mm into the surface providing capillary coating.
An unprotected building can absorb over 1 liter of water per sq. ft in 6 hours. A concrete block can absorb 2 liter of water. The rain water absorption causes multiple damages to the buildings such as penetration of water through the walls, cracks caused by swelling & shrinkage, destruction of concrete by corrosion of reinforced steel, lime leaching, chemical corrosion, binder transformation, etc.
