Concrete is tough—but it’s not invincible. Water, salt, freeze–thaw cycles, and everyday environmental stressors slowly break it down, leaving surfaces stained, cracked, or weakened. That’s where GhostShield Siloxa-Tek 8500 steps in, offering one of the most advanced protective solutions on the market for homeowners, contractors, and commercial property managers looking to extend the life of concrete.
This proprietary, nanotechnology-driven sealer doesn’t just coat the surface—it penetrates deep, reacts within the material, and creates an invisible, breathable shield designed to last for years.
Why Water, Salt, and Freeze-Thaw Cycles Are Concrete’s Worst Enemy
Concrete naturally contains pores and capillaries, which act like tiny channels that attract water. Once water enters, it brings along deicing salts, chlorides, dirt, mold spores, and other contaminants. In winter months, trapped water expands during freezing, leading to flaking, cracking, and long-term structural damage.
A premium penetrating sealer is the best line of defense, and Siloxa-Tek 8500 is engineered specifically to address all these vulnerabilities from the inside out.
What Makes Siloxa-Tek 8500 Different?
🔬 Advanced Nanotechnology for Deeper Penetration
The formula uses high-performance iso-octyltriethoxysilane, a molecule significantly smaller than traditional silane/siloxane blends. This allows the sealer to penetrate deeper into the concrete’s pore structure, creating long-lasting protection at the molecular level.
💧 Exceptional Water & Salt Repellency
By altering surface tension inside the pores, Siloxa-Tek 8500 creates a hydrophobic environment that repels:
-
Water
-
Chloride ions
-
Deicing salts
-
Freeze–thaw moisture
The result?
A dramatic reduction—up to 96%—in water and salt absorption.
🌬 100% Breathable Protection
Unlike film-forming sealers that trap moisture, this product:
-
Allows concrete to breathe
-
Prevents peeling, flaking, yellowing, or delamination
-
Avoids the moisture-related damage caused by non-breathable coatings
Your concrete maintains its natural look while gaining incredible resilience.
⛏ Increased Durability & Reduced Maintenance
Siloxa-Tek 8500 helps prevent:
-
ASR / alkali attack
-
Efflorescence
-
Dusting
-
Spalling
-
Pitting
-
Cracking
-
Mold and organic growth
Because the protection works from deep within the surface, the concrete stays cleaner, stronger, and easier to maintain over time.
Industry-Trusted and DOT Approved
GhostShield’s Siloxa-Tek 8500 isn’t just homeowner-friendly—it meets or exceeds Department of Transportation specifications, proving its performance under high-traffic, high-stress conditions.
Independent testing has verified its longevity, hydrophobic performance, and chloride-screen effectiveness.
That makes it ideal for:
-
Driveways
-
Sidewalks
-
Patios
-
Garages
-
Parking structures
-
Commercial floors
-
Polished and honed concrete
-
Any horizontal surface exposed to heavy traffic or the elements
Easy, Ready-to-Use Application
Siloxa-Tek 8500 is ready straight from the container—no diluting or mixing required.
Simply follow the instructions on the product label for best results.
Once applied, the surface:
-
Maintains a natural, flat finish with zero discoloration
-
Resists UV breakdown
-
Forms a deep, durable barrier that won’t flake, peel, or yellow
It’s long-lasting protection without changing the appearance of your concrete.
