The Siloxa-Tek 8500 Ultra Concentrate is a versatile and robust concrete sealer designed to protect various surfaces including concrete, brick, masonry, and pavers. As a water-based silane/siloxane sealer, its strong suit is its ability to penetrate deeply, providing long-lasting protection against water and salt intrusion without altering the look of the treated surface. This makes it ideal for preserving the natural appearance of your driveways, garages, basements, patios, and pool decks.

One gallon of this ultra concentrate can cover up to 250 square feet per coat, making it economical as it produces up to five gallons of usable sealer. The application is user-friendly, as it can be applied using a sprayer, roller, or brush. It is also D.O.T approved, ensuring reliability in preventing surface damage from chlorides and deicing salts, and is effective in mitigating issues like cracking, spalling, and pitting due to freeze-thaw cycles. Being UV stable, the Siloxa-Tek 8500 does not degrade under direct sunlight, contributing to its durability.

Users should be aware that the product's effectiveness is highly dependent on proper application, and while it offers impressive protection, the initial cost might be higher compared to some other sealers on the market. Additionally, as a commercial-grade product, it might be more than what is necessary for simple, small-scale household projects. Nonetheless, for those needing reliable, long-term protection for larger and more demanding surfaces, the Siloxa-Tek 8500 is a solid choice.

Siloxa-Tek 8500 is a penetrating concrete sealer that excels in water and salt repellency, making it ideal for driveways, garages, basements, patios, and pool decks. It offers extensive coverage, up to 250 square feet per gallon per coat, and is easy to apply using a sprayer, roller, or brush. One notable strength is its UV stability, which ensures the sealer won't fade, yellow, peel, or delaminate under direct sunlight. Furthermore, it is D.O.T approved, meaning it meets high standards for resistance against damage from chlorides and deicing salts, effectively mitigating cracking, spalling, and pitting caused by freeze-thaw cycles.

The finish is clear and natural, preserving the original appearance of concrete, brick, masonry, and stone surfaces. Additionally, the sealer is breathable and non-film forming, preventing issues like peeling and flaking over time. The high actives formula promises long-lasting protection, potentially lasting up to 10 years for vertical applications when installed by a certified applicator.

One drawback is the limited coverage compared to other products, which may require more sealer for larger projects. Another potential downside is the higher upfront cost due to its commercial-grade formulation.

The Siloxa-Tek 8510 is a penetrating concrete sealer designed to protect garage floors, driveways, and walls from water, salt, and oil damage. It works by soaking deep into the concrete and creating a water-repellent surface that helps prevent stains and moisture damage without changing the look of your concrete, thanks to its clear, natural flat finish. This sealer is breathable, meaning it allows moisture inside the concrete to escape, reducing risks like cracking or spalling caused by trapped water.

It also offers strong resistance against salt and chloride, which is great if you live in an area that uses deicing salts in winter. One of its standout features is the oleophobic property, which makes oil and grease easier to clean, helping keep surfaces looking good with less effort. The product dries fairly quickly and remains durable under sunlight without breaking down.

This sealer is ideal for those looking to extend the life of their concrete surfaces with a long-lasting, low-maintenance solution that keeps the natural look intact.
