Nanoseal is a new product that uses a new technology to render all natural stone waterproof and impervious to stains. This product is for use on granite (which is already pretty stain-resistant), marble, travertine, limestone and anything else you can think of. Imagine, now you can make a shower enclosure out of travertine and never worry about what the water's doing to the stone. Amazing.
This process also overrides any concerns anyone could ever have about marble. The thing I love most about it, it's living and moody nature, can be circumvented completely with a single Nanoseal treatment.
I have see this stuff live and that video is no exaggeration, Nanoseal delivers as promised.
Nanoseal uses nanometer-sized particles that bond with virtually any surface. These carbon-based nanoparticles form a covalent bond with the targeted surface that cannot be broken. Keep in mind that a nanometer is a billionth of a meter, so all of this happens on the molecular and atomic level. These nano particles bond and organize themselves in a single layer and this layer is so thin that it doesn't change the appearance of the material being sealed.
Stains on stone happen when a material gets lodged in the incredibly tiny pits and fissures that make up the surfaces of most counter materials. These nano particles effectively fill in those pits and fissures, so nothing can get in there in the first place. As a side note, this new nano surface treatment prevents not only stains from getting a foothold, mold and bacteria can't attach to it either. Fascinating and a real case of better living through modern chemistry. Nanoseal is available from most natural stone fabricators and it can be applied to existing counters, floors and walls as readily as it can new ones. Call your granite fabricator and ask about it.
