Brian is a very busy new businessman with this company. My condo board had the steps on 22 condo units resurfaced with RubberKrete a couple of years ago. On my unit the rust from rebar was coming through. Brian stopped by in his busy schedule to wire brush some rust stains away. I'm generally happy with the product, but just wish my condo board had been more thorough in preparing the steps before the application of RubberKrete.
