Lithi-Tek 9500 vs Siloxa-Tek 8500

The Lithi-Tek 9500 concrete sealer and Siloxa-Tek 8500 are both lithium-silicate concrete sealers that penetrate the concrete to densify and strengthen it.

Lithi-Tek 9500 is the better-performing sealer overall:

  • It penetrates deeper (up to 1/4 inch vs 1/8 inch for Siloxa-Tek 8500)
  • Provides better water repellency and protection against deicing salts
  • It can be applied by spraying, rolling, or squeegee, while Siloxa-Tek 8500 requires a sprayer

The tradeoff is that the Lithi-Tek 9500 is a bit more expensive compared to the Siloxa-Tek 8500.

So, if you want maximum concrete preservation, choose Lithi-Tek 9500. But if budget is more important, Siloxa-Tek 8500 still offers good performance for the money. Both sealers are much better than acrylic sealers in terms of durability and longevity.

Overall, Lithi-Tek 9500 and Siloxa-Tek 8500 are both excellent lithium silicate concrete treatments.

Lithi-Tek 9500 has a slight performance advantage for deeper penetration, water resistance, and salt protection. However, the Siloxa-Tek 8500 is a bit more affordable. However, Lithi-Tek 9500 is worth the extra investment.


For anyone looking to preserve, strengthen, and waterproof existing concrete, Lithi-Tek 9500 Concrete Sealer & Densifier is an excellent product choice.

User reviews consistently praise its long-lasting performance and ability to harden and repair deteriorated concrete.

While more expensive than basic sealers, it’s a smart investment, given the durability and added life it provides. With proper prep and application, Lithi-Tek 9500 will provide decades of reliable protection.
