The roof tile samples were manufactured for a roof tile company in Kansas City, Missouri 18 years ago. The tiles have been outside in an ice storm, snow, cold, hot, rain, etc. climatic conditions without any failure at all. The mix design included 3 ounces of Kel-Crete Premium Liquid Admixture per proprietary mix. The finished tiles were then coated with Kel-Prime mixed 50/50 with water.

I wish I could give you the manufacturer data, but it was required we sign a nondisclosure form. As I have stated before, products or projects using Kel-Crete admixtures, and Kel-Prime curing/bonding/sealing/hardening agent got better with age. To date no contractor using our premium, non-toxic products has ever spent a dime in litigation issues.
