## Description

desertcart.com: Prosoco Cat 5 Air and Waterproof Barrier, 5 Gallon : Industrial & Scientific

Review: Shipping was faster than any wholesaler could deliver. - Giving the shipping speed five stars. I ordered on a Friday and it arrived the following Wednesday. My local wholesaler was giving me 1-2 week delivery. As for the product itself, its easy to apply with a roller, but it can get messy. You have to mix it for five minutes before you can roll on. I used 1.5 buckets for 3 sides of an 1100SF house. I also did two coats. I used the remainder as waterproofing in the bathroom. We then added hardie siding directly on top of the Cat 5. I used the full system, fast flash for the windows and joint and seam filler, which my local wholesaler had in stock. This is my first time using this product so only time will tell if it's truly effective.
