Fantastic product! GET THIS!! Long Lasting!!!
GhostShield does what it claims to do - very well. I purchased GhostShield 8500 for cement, a block brush and sprayer. Look at that shine, water floating on my sidewalk! Mesmerized neighbors will be applying GhostShield in the spring.

Water Repelency Works!
I used a sprayer to apply it. It was very easy. I was wondering how do I know it is working. Then, after a light rain, attached is what I saw. Water replelency works!

Wonderful product
I used this on the inside bowl of a large century-old concrete birdbath. There were many fine cracks and three decent cracks. I was concerned about water continuing to get inside the concrete. So I researched online and found Ghostshield 8500. Hadn't heard of it. I let the birdbath dry thoroughly outside in the sun for three days. Follow the directions. Works wonderfully: no change in the color of the concrete and no leakage of water into or through the concrete. Not cheap, but the 16-oz. size was more than enough for this application.

While this stuff isn’t cheap, I believe it’s worth protecting your investments. I applied with a pump sprayer to our garden box and as you can see it seems to be working well. No change to the appearance of our blocks. I hope we get 5+ years but time will tell.

As Advertised
I was skeptical at first, couldnt see how such a product could water proof concrete and be applied so easily. I power washed our 10 year old driveway, let it dry for a few days then applied this product using a pump sprayer in the early morning so that it didnt instantly evaporate giving it a chance to penetrate the concrete. Dont be fooled, pictures of results are attached. Driveway looks great, water just beads, one picture compares my sidewalk to my neighbors un treated driveway.

This product performed superbly just as the reviews said it would. Easily applied with a roller, easily cleaned up and with the first rain the water beaded up like little marbles and ran in rivers off the patio. Excellent product and worth every penny!

We recently purchased our first new home and wanted to make sure we sealed the driveway, small walkway and stairs leading into our house at our builders suggestion. He recommended a couple of options and this was one of them. We are not the handiest people out there but this was one of the easier projects we did. The sealer was concentrated, we mixed it with 4 gallons of water and opted to roll it onto our concrete as opposed to spraying it as also suggested. We worked in small areas sealing each section twice before doing the next section. The sealer dried completely invisible however anytime it got wet with snow and it melted, throughout the winter you could clearly see that something was there protecting the concrete. Great product, highly recommend it.

Water really beads up!
So far, this stuff seems to work great. We had a rain a few days later and I noticed a color difference between my sidewalk and the neighbor's sidewalk. His was darker in color (the water soaked into the concrete) and mine kept the same light gray concrete color and the water beaded up during the rain. Let's hope, over time, that the mildew doesn't come back and that it last for several years (10).
