An industrial-grade, water-based, silane/siloxane engineered to reduce water and moisture intrusion, while protecting concrete or masonry substrates from chlorides and deicing salts. Siloxa-Tek 8500 is our favorite product to treat nearly any application. A proprietary blend of silane/siloxanes, this clear penetrating sealer not only prevents deicing salt and freeze-thaw damage, but its hydrophobic nature resists moisture intrusion and vapor transmission. This is the go to choice to seal any concrete, brick, or masonry based substrate especially driveways, basements, patios and garages.

  • Prevention from freeze-thaw attack and ASR by preventing the ingress of water, prevents further damage to reinforced concrete by limiting the substrate water content, chloride and other aggressive salts
  • Provides increased protection as a hydrophobic barrier to prevent future penetration of water and soluble aggressive agents through a crack, provides protection from spalling and pitting as a result of aggressive salts and chlorides
  • Alkali resistant, freeze-thaw/de-icing salt resistant, UV resistant, reduces vapor transmission, water beading (water repellent effect), reduction of dirt pick-up, reduces risk of efflorescence, protection against micro-organism growth
  • Supplied ready to use, easy to apply, effective penetration depth, seals pores and capillaries while remaining breathable, no change in appearance of the substrate, the treated surface does not become glossy, tack free, durable finish, no formation of harmful by-products, low VOC's

Customer Questions & Answers

Can this product be used to seal an interior block basement wall?

Asked by: JOHN
GhostShield recommended that I first prime my cinder block walls with Sil-Tek 3500 before applying the 8500.

Application Temperatures

I have a set of concrete stairs that were parged and patched 2 1/2 weeks ago. I am most interested in applying 8500 sealer now to prevent any water intrusion that might freeze and cause spauling. Present daytime temperatures are running 45-50.
Asked by: John
Concrete sealer is a chemical mixture that contains particles of chemical sealant suspended in either water or a chemical solvent. Either way, the sealers have to be stored and applied at certain temperatures to be at their most effective. To begin with storage, concrete sealers should not be stored frozen, nor should they ever be at risk of freezing. A frozen concrete sealer will feature less effective particles of chemical sealant, rendering if significantly less effective when it actually is applied (though you may not be able to tell the difference). As many concrete sealers are water-based, which are undoubtedly better concrete sealing options, they are also at risk for freezing . The surface of the concrete and the environment of the room in which the concrete sealer is being applied should not dip below around 50 degrees Fahrenheit. Below 50 degrees Fahrenheit, the concrete is too cold to allow the concrete sealer to penetrate or bond to the surface effectively, depending on which type of sealer you are using. The concrete and the room in which it is being applied should not exceed approximately 90 degrees Fahrenheit either, nor should it be applied in direct sunlight.

I have a leaking second floor balcony with ceramic tile will this product work to stop the leakage?

Asked by: Jotto
While our Siloxa-Tek 8500 can help to seal grout between tiles, at this time we do not have a sealer suitable to protect ceramic tiles.

Asked by: Ruslan
For water repellency and salt protection, our Siloxa-Tek 8500 is a great choice. Alternatively, for all the same benefits with added oil resistance, you could use our Siloxa-Tek 8505. Both of these sealers will absorb into the surface without changing the appearance, and will continue to provide excellent protection.

1 gal. Invisible Penetrating Water Based Concrete and Masonry Sealer Plus Water and Salt Repellent is rated 4.5 out of 5 by 25.

We recently purchased our first new home and wanted to make sure we sealed the driveway, small walkway and stairs leading into our house at our builders suggestion. He recommended a couple of options and this was one of them. We are not the handiest people out there but this was one of the easier projects we did. The sealer was concentrated, we mixed it with 4 gallons of water and opted to roll it onto our concrete as opposed to spraying it as also suggested. We worked in small areas sealing each section twice before doing the next section. The sealer dried completely invisible however anytime it got wet with snow and it melted, throughout the winter you could clearly see that something was there protecting the concrete. Great product, highly recommend it.

Rated 5 out of 5 by from Top Quality Product Product is as advertised. Very easy to apply and results are fantastic. I used this to seal my brick and stonework on my front porch. Once the rain came the water beads up like a newly waxed vehicle. Very satisfied with the performance I just wish the price was more affordable. I will look for similar products at a better price point though. I will have to say that I will never go back to a surface sealer. These penetrating sealers are far superior.

We needed a solutions to seal a concrete porch over our garage. We have used other products in the past that inevitable failed after only a few short months. We applied this product back in April and 8 months later it is still performing exactly as it claims that it does. So far, it has lasted longer then anything else we have tried, we would recommend this product.

Rated 5 out of 5 by from Great sealer!! After cleaning the concrete and letting it dry for a day the Ghostshield went on easily and evenly with a pump sprayer. It does a great job of repelling water as it all beads up and runs off. Icy spots in the MN winter are a side affect due to the fact that it repells water so well that it freezes up in beaded up form during freeze thaw cycles. Seals concrete well! Worth the price tag so far.

Rated 5 out of 5 by from Perfect product for the application Problem to be solved: water penetration into brick chimney and damaging drywall ceiling below the roof. Previously repaired the cement cap on the chimney, placed caps over the flue pipes, reflashed the chimney. Waterproofing the masonry was all that remained to be done. The Ghostshield was applied with a brush. The first coat was absorbed almost immediately. Yje second coat was absorbed, but much more slowly, indicating that the material was penetrating the masonry as described. Upon completion, the chimney looks exactly as before.
