Ghostshield Siloxa-Tek 8500 Ready to Use - 1 Gallon Penetrating Concrete Sealer, Water and Salt Repellent. Clear, Water-Based DOT Approved Silane/Siloxane for Concrete, Brick, Masonry & Pavers

Very good product super easy to use with a spray. highly recommend it.

Pricey but worth it. I originally applied a few years ago. I stopped at the top of my steps. Whenever it rains, you can see the product still protecting where I sprayed. It's more cost effective to order the concentrate. I ordered the ready to use as I needed just a little more. Read the detailed description how this product works and it'll make more sense why it's pricey. Long lasting too.

Years ago, I used Thompson water sealer. The product changed over time; was milky and waxy when applied. I tried this product instead and have used it twice. The first time was for my chimney, which would leak when hit with high winds and driving rain. It sealed superbly; no leaks *at all*, ever. Then I purchased more to seal a concrete pad, and some touch up the chimney just in case. It's very easy to apply with a simple pump sprayer and performs exactly as advertised. This product is a winner; hope they don't change a thing about it.

Exactly as advertised and at a great price!

Application was easy for a novice using a roller and went on even, covering my patio in two coats as instructed. So far has been good for water repellant and dirt cleanup, and did not change the color or sheen of my concrete. Would probably rate a 5 , just need to see how it goes after a few more months.
