In reading the 100k house blog (fantastic blog based in my old stomping ground, Philly), I came across a mention of Eco Tuff Industrial Floor Coating. I did some research and found this information from the product's website:
"Eco-Tuff is a single component, zero VOC, high build, high flex ultra tough waterproof coating material. There are no hazardous ingredients, is non-flammable and virtually odorless. It is engineered for the most extreme environments from freezing cold temperatures to the hottest climates around the world. It is capable of withstanding abrasion, UV, chemicals, hot tire pick-up, and submersible applications. May be used on concrete, wood, fiberglass, and metal surfaces."
It looks like an interesting product. It's very green: non-hazardous, zero VOC, LEED compliant, and includes recycled content. Plus, it is waterproof, abrasion resistant, stain resistant, UV resistant, and does not chip, flake or peel. It is a self-leveling material that rolls or sprays on like an epoxy floor and can be applied directly over a plywood subfloor. Assuming competency on the part of the flooring subcontractor, it can give you a smooth finish very similar to that you'd see on factory floors or in industrial warehouses. It comes in a variety colors and several shades of grey, the color we would probably pursue.
This might be the perfect fit for our first-floor needs. We have been looking for something industrial and modern, not too hard (got to watch out for the pups' joints), and eco-conscious. Oh, and did I mention it's relatively affordable? Here is a picture of it applied.
Also, the company provides top-notch customer service. I emailed them yesterday to find out whether the product is compatible with radiant heating systems. They said it would be fine and the heat would pass through the flooring material without a problem. Sounds too good to be true!
