I talked to Ed Harris about a coating to apply to concrete. He seemed knowledgable and represented the product well. When we received the material, we ran a sample test before coating a complete floor. The material didn't harden. It was soft and squishy. I called several times, leaving messages. No response. Finally, Ed picked up the phone directly. He, again, seemed intent on solving the problem and said that he would send out a hardener to add and then follow up to make sure everything went well. Instead of receiving hardener, I received a can of clear material. I again made the rounds of calling and calling until I finally caught Ed. He told me that if I added the clear to the other material it would act as a hardener. It didn't. Now, I am requesting a refund because the material won't harden, but again am caught in the endless loop of calling, leaving messages, getting no response, and calling again to try to catch Ed. read more
