A while ago a client/friend called and said, “Chuck, I’m seeing your Kel-Crete Premium Liquid Admixture and Kel-Prime (a curing/priming/hardening/fire resistant agent) specified more and more frequently. You must be doing something right.” I told him our non-failure history gets all the credit for them being specified. This is supported by 58 years of meeting EPA Leeds Standards for being non-toxic. (See independent laboratory testing on this web site.) Additionally these two products meet EPA carbon footprinting without failure. Should you care to discuss this subject matter further please call our office at 800-845-1833.
