SenGuard marble & granite sealer represents the next generation in sealer chemistry. Utilizing nano-technology and super-small specially engineered molecules, SenGuard penetrates more 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 providing the most durable, long-lasting stain protection available.
Ounce per ounce SenGuard will cover and seal far more stone than conventional sealers. One bottle covers an estimated 50 - 200 square feet depending on the porosity of the stone. Each stone is different and results may vary.
Requiring only a single application using a lower volume of sealer means SenGuard is more environment-friendly than conventional sealers which require multiple applications of a large volume of sealant.
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.
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 engineered to provide permanent 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 quickly absorbing the liquid like a hard sponge, it just beads up on top of the stone dramatically delaying absorption for easy cleaning.
Application: One bottle of SenGuard will cover an estimated 50-200 square feet depending on how porous and absorbent the stone is. Every stone is unique so results may vary. 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.
Also, depending on the porosity of the stone two coats (or even three for very porous stones) may be necessary to properly seal the stone in one application. Simply perform the water test (click here) prior to application to determine how porous your stone is and estimate the possible necessity of a second or third coat.
Performing the water test after the first coat has cured for 24 hours will help determine if the stone is effectively sealed or if a second coat is necessary.
Performing a "test" application on a left-over or sample piece of the stone to be sealed is also advisable to help determine the coverage required for an effective application.
Sealer Myths: It's important to understand that many myths and misconceptions abound regarding sealers and sealing granite countertops. No impregnating sealer will "absolutely prevent" a stain. Sealers work by radically reducing the rate of absorption of a stone. So, the advantage of applying a sealer is that it allows far more time to clean up a spill. If neglected, a liquid exposed to the surface for an extended period could still potentially stain no matter what type or brand of sealer used.
The advantage of applying SenGuard is that the permanent bonds will not break down with use and exposure to cleaning products like other sealers, so it remains effective while others sealers will require regular re-application.
For complete, detailed information regarding sealers and sealer application please consult the All About Sealing ebook.
Chemical Etching: SenGuard sealer will not protect against chemical etching by acidic compounds. No impregnating sealer will prevent chemical etching that leaves dull and light-colored spots on calcitic stones like marble, travertine, limestone and (rarely) some granites.
Free Shipping: You will not be charged shipping costs on the SenGuard product which ships separately (per manufacturer) from all other products. However, a handling fee may still apply and shipping costs for any other product ordered will still apply.
