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

Works well. Easy to apply with sprayer. Water is repelled very well.

Had a new driveway and new sidewalk installed, and the installer recommended putting a sealant on it after letting the new concrete dry for 30 days. Dancing around fall leaves and rain, we were able to seal the new concrete using two methods. Used a roller for part of it and, because our tank sprayer broke we turned to a small hand-held bottle sprayer to finish up and it worked fine, although it took a little time. It has a viscosity close to water and sprays easily. Two coats, as recommended, appears to be important. We ordered one bottle, which was not enough to cover our entire driveway but was enough to cover a sidewalk. We liked the results enough so that we ordered more to complete the task. Water from rains bubbled up nicely for the first couple of months, which gave us an indication that we'd covered the entire targeted area. Neighbors liked the look. There was no color change to the concrete. It just makes an area look damp when it's sprayed on. Three fall months after its application, it's still doing its job and the driveway looks good.

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

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

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.
