SenGuard: New & Advanced Granite Sealer
SenGuard marble & granite sealer represents the next generation in sealer chemistry. Utilizing nano-technology and super-small molecules, SenGuard penetrates deeply into your stone increasing the contact area for stronger bonding and more complete coverage.
The result is a permanent protective barrier that chemically repels oil and water while still allowing your stone to breath, as it should.
Use it for sealing granite countertops, floors, outdoors, marble, travertine and all other porous surfaces. It will not change the look or color of your stone and UV rays do not affect it, so it's effective for outdoor use as well. Your DIY natural stone countertop sealer kit includes a "how to" DVD video, step-by-step booklet, applicator and finishing cloth.
The Difference
Other top marble & granite sealer brands on the market today use fluoro-carbons, fluoro-Teflon or acrylic polymers to make very good sealers that in some instances offer 5 to 10 years of protection.
However, these chemical compounds contain much larger molecules that do not penetrate as deeply or bond as well. In most cases, you will need to re-apply the sealer in 2 to 5 years.
Now this is vastly improved from what sealers could do just a short while ago, but SenGuard is the next step in the evolution of sealer technology.
SenGuard's cutting-edge sealer is designed to provide 15 years of protection with only one application. It is more expensive. However, long-term it is the better value when you consider that you'll have to buy and apply any other sealer many times to get the same protection.
The Whole Story
For those who want to know all the details...
SenGuard contains specially engineered modified silane polymer molecules. These molecules are thousands of times smaller than other sealer types. Thus, these molecules are able to penetrate far deeper into the stone and to spread into every pore, crack, fissure and crevice more effectively so you get more consistent and complete coverage. This is especially important for sealing granite countertops in the kitchen.
These molecules are also engineered to form chemical bonds directly with the stone that are as strong as the bonds holding the stone itself together. When applied to granite or marble, etc. a reaction takes place. Part of the molecule is attracted to water, so it is drawn into the stone by water molecules in the stone.
The specialized molecule then breaks apart while displacing the water molecules. It leaves behind a hydrophobic and olephobic molecule that binds directly with the stone lattice. The remaining molecule chemically repels oil and water like opposing magnets repel each other.
Other marble & granite sealers rely on weak hydrogen bonding and mechanical holding (clogging the pores). SenGuard becomes part of the stone itself while still allowing it to breath, as it should and doesn't change the look or slip-resistance of the stone.
The net effect of this reaction is to change the "surface energy" of the stone. All materials have surface energy. A low surface energy liquid like oil will penetrate a high surface energy material like granite.
The molecular bond created with the stone by the SenGuard sealer changes the surface energy of the stone so that it becomes lower than oil or water. Thus, when you spill something, instead of the stone absorbing the liquid like a hard sponge, it just beads up on top of the stone for easy cleaning.
Application: One bottle of SenGuard will seal 50-200 square feet depending on how porous and absorbent the stone is. It's important to let the stone absorb as much sealant as possible (without letting it dry on top) rather than trying to spread the sealer around to cover as much as possible.
One properly applied coat is much better than two thin ones.
NOTE: This is a solvent-based product and by law requires special handling during shipping. A $15 fee is added to the standard shipping charges calculated by the carrier to cover this cost and will be reflected in your total purchase price.
