EXCEL NanoSeal by its name indicates a Super Hydrophobic, water repellent coating. Unlike various film of coating, EXCEL NanoSeal does not seal the pores at the surface of the 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 up to 90%.
It penetrates through all the micropores and cracks in the concrete and makes it completely water repellent. Since it is a Nanoparticle and it covers all the pores and cracks, it does not allow any penetration of water through the treated surface.
On the surface treated with EXCEL NanoSeal, the drop of water is repelled and stands in the form of the bead and does not penetrate inside.
The size of EXCEL NanoSeal is 4 – 6 nm (0.005 microns) 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.
