Siloxa-Tek 8500 Ultra Concentrate - 1 Gallon (Makes 5 GALLONS) Penetrating Concrete Sealer Water and Salt Repellent. Clear Water-Based DOT Approved Silane/Siloxane for Concrete Brick Masonry & Pavers

Easy to use, easy to apply. Met all my expectations. Was very happy with it.

I had read a review that estimated longevity could be ~10 years before reapplication. After first use in 2019 for a concrete pool deck, I am reapplying after 4-5 years due to mold and dirt buildup. Though longevity is disappointing, I still prefer the water resistance and color fastness of this product.

Very easy application, if one follows the instructions. Two coats dried quickly and was water repellent after 4 hours. Applied on 1300 SF of exterior steel troweled patios, as well as a broom finished walkway. The process went flawlessly on the patios, yet soaked in quickly on the broom finish walkway. I applied to saturation point both coats on the walkway. Both patios and walkways dried without cloudiness or hazing. Very please, and will definitely apply again, in a few years.

This product works!!!!! It works on concrete and stone. Period end!!! We put this on our Tennessee field stone coping around our pool. Our issue was the fieldstone will flake off if water gets under the layers. I wish I knew that before using it as coping around my pool. We used the stone on the fireplace which is on the patio as well to match. Anyways, the water just beads up like the picture shows. This is about 9 months later so I can not attest to the longevity of it but here is the deal. I got a gallon of the concentrated stuff to make 5 gallons. I mixed it in a 5 gallon bucket from Lowes. I did three coats around a 18 x 36 pool and a hot tub and I still have 4 gallons left. I used a paint roller and my wife got in the Pool and put the stuff on the edges. We used a big container lid in the Pool to catch the drippings that fell. No question it was a 2 person job for a pool. Now the down side is....we were not quite as detailed on the edges on the concrete.......well it works there too! You do notice the color difference on the concrete when it rains....it's whiter. But zero difference when it's not wet. BTW no color difference on the stone at all. However be sure not allow it to dry between coats. It will give a cloudy look to the stone dry or wet.If you want to seal stone or concrete. This is the stuff!!!!

The water beads up on pavement now
