Great product and easy to use

This product is easy to use and work with. Mixing instruction is 1 gallon of mix for 4 gallons of water. Easy to understand the ratio, would be nice to have a chart for reducing the container size, but some common math and you should figure it out. Also, the densifier works too. We used bagged concrete and needed a harder surface to prevent water damage or leaking in our shower floor.

Easily applied and super effective.

We had a new pathway and a stamped concrete border put in this summer. I just had everything power washed in preparation for the winter and decided to go with Ghostshield for the first time.  It was so easy to spray on! And I could let my dog out within hours of application. It rained the next day and was already repelling water like crazy. I'll buy it again!

5 Stars

I have a 2-inch reinforced poured concrete garage top that was constructed in 1971. I recently had the top power cleaned and treated with two coats of Ghostshield 9500 in Oct. 2016. What a fantastic product. When it now rains, water beads on my top resembling Saran Wrap just out of the shower. I'm SO GLAD I learned about this product! So penetrating is this product that a pinhole, the size of a pencil point, that I had prior to coating marked on the underside with a pinch of masking table, was observed with the tape itself englazed in the 9500. I'll definitely be one to recommend this great product! Keep up the great waterproofing products!
