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

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.

Recently ordered my second gallon jug of this awesome product. Sadly, I miscalculated how much I would need for my project and had to split it up over the course of a couple weeks, but the results are awesome. First time using a concrete sealer, this all in one solution makes it easy. Threw it in a sprayer and went to town on my garage and walkway. This second gallon is for the rest of my driveway. So far after a week of rain, the results are great! Water puddles up and bounces off the concrete.Now the first time I ordered this, it came in a product box and an Amazon box, which resulted to it leaking all over my brand new front porch which left a white stain mark due to poor delivery. I messages Amazon but nothing was done regarding this. Not the products fault as the delivery was to blame, but be careful and be sure to evenly spread once you apply. The packaging on the second gallon ordered was much better! Tightly packed in with more cardboard, I could tell they must have had issues with bad deliveries since mine. Glad to see it get fixed and will gladly recommend this product for future projects.

Product works great. Very easy to apply and can’t even tell it’s on there until it gets wet and beads up. Very happy with purchase.

We used this for our driveway. It did the job of waterproofing for1 year. After a year it started losing the capacity.

This product was extremely easy to use!

This product was recommended to me by a friend who recently used it with good results. I used it to reseal my stamped concrete patio. It was formerly stained, which this cannot be used on, but all the stain and sealant was gone. It was easy to apply, dried clear as advertised, and clearly keeps water from penetrating the concrete. It has only been applied for a month or two and has only seen a few rains but no snow yet, so cannot speak to durability or longevity, but seems promising

I bought this to seal an outdoor concrete counter for my B-B-Q. It gets full sun and has faded. I sanded the concrete and applied this material at first. The counter is a deep brown tinted concrete and when wet or prior sealed, becomes a rich deep color.Pros:-Easy to applyCons:-No color enhancement-No shine at all-No visible change that a coating was even applied at allI did about 30% of the counter and realized that this material was worthless. I bought a solvent based acrylic and finished the rest. Totally different. Back to deep, rich color with a semi-gloss finish.

Great product
