Patio project
Very pleased from ease of application to the end results in protecting my diy patio project. You can see how well the water beads up after rain.

Customer review from Ghostshield Concrete SealersApr 1, 2023
Works as advertised
I needed to seal the cement pad outside my front door as the idiot builder didn't apply waterproofing "before" creating the pad. Instead, they waterproofed "around" the finished pad. Well that doesn't help when the rain pounds water "into" the top of the pad and then into the wall of the basement. Argh! So GhostShield to the rescue.....I apply this about every 2 years to repel the water off the pad. Helps about 95% but rain is very persistent, and it faces the Southern sun.

EXCELLENT!
Easy application. 2 coats went on easily. The next day the concrete was showing beads of water on top! The clear natural seal was perfect for our silo, cement base to the barn & the entry steps. Thank you!Highly Recommended :)

WORKS BETTER THAN ADVERTISED
AWESOME!! Hard to believe how well this sealed old sand concrete. Water now beads up like a waxed car. I even brush some on a PT swing. Beads up as well.

Driveway sealing project
The rating is for ease of use and application. Too soon to rate for endurance and longevity of protection. Product more user friendly than expected. Easy to mix, did not clog the sprayer, rolling was easy. Cleaning the sprayer was quick and easy.
Our western Massachusetts weather was the only thing that concerned us. We thought if we applied the sealer end of September we would not have to deal with the heat..that we would have time to work in the coats before it started to dry…but we got rain and wind every other day so we split the project over 2 days that would have sun for a couple days after the application. All went well.
We completed the coverage this weekend…today the mailman came to deliver mail and saw all the pearls of water beads on the driveway….he decided to walk on the grass instead…I have no clue what he thought it might be…but we love the dry cement look, the brightness makes the driveway pop!

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.
