The Siloxa-Tek 8505 is a revolutionary product that is able to repel salts (including deicing salts), oils and stains from household products, automobiles, bbq grills, leaves and more. Of a silane/siloxane chemistry with an added proprietary component this product is unrivaled when it comes to sealing driveways, warehouses and patios to name a few. This product leaves a completely clear, natural finish so once you apply it, you wont even know it is there except when water, and fluids are spilled on the surface and they bead right up like a newly waxed car.
A lot of manufacturers claim their products will “limit the penetration of stains”; however, this is different and must not be confused with a sealer that is formulated to actually repel stains and oil like the Siloxa-Tek 8505. The manufacturer would not give away the proprietary ingredient but we tested it in comparison to the products that claim to limit the penetration of stains and there is no comparison. The proprietary ingredient in the Siloxa-Tek 8505 is extremely effective and performs as described on the technical data sheets and the manufacturer is actually able to provide testing data on request.
This product is available in two variations, a water based version for residential applications and small commercial applications or a solvent based version for larger commercial applications. The water based version is available in a ready to use formulation or a ultra concentrated version (both are readily available for purchase through Lowes.com and if you prefer, formally known as the Siloxa-Tek 8500 OR, The Home Depot.com carries the ready to use version). The ready to use product will cover 125 sq. ft. per container for both applications and the ultra concentrated product will cover 625 sq. ft. per container for both applications. If you are looking for industrial or commercial use of this product, it is also available in a solvent based version is called Siloxa-Tek 8510 and is available through the manufacturer in 1 gallon, 5 gallon bucket or drum quantities.
When it comes to application it could not be easier to apply. A garden variety sprayer, or nap paint roller is recommended. Two coats are highly recommended and upon talking to the manufacturer they essentially require it. The coats are applied wet-on-wet. What wet-on-wet means is that the second coat is applied before the first coat has dried. Because the product is so hydrophobic if you try to apply the second coat after the first coat has dried the first coat will try to repel the second coat. However, if you apply the second coat while the first coat is still wet you are able to get the product to penetrate as deep as possible and ensure the longest lasting performance. A good rule of thumb is to apply a first coat to a 500 square foot section and go back and apply the second coat to the same 500 square foot section and then move on to the next section and apply a first coat, then second coat. (You can walk on the first coat to apply the second coat, since it is a natural finish product it will not leave footprints).
What we love most about this product is that it does not need to be reapplied every year or even every few years but the product has a lifespan of up to 10 years before needing to apply another 2 coats. We recently came across this distributor, Concrete Sealer Solutions, which has the ultra concentrated version on sale for $15 less than Lowes! Since the product is concentrated, the price breaks down to about $50 per gallon, quite a bargain when it comes to protecting a concrete driveway from spalling, pitting, cracking, deicing salts, oil, auto fluids and leaf staining.
