This is a complete system sold by the square foot. To order, enter the square footage of your floor rounding up to the nearest 100 sq ft increment. For example if you have 1240 sq ft you would enter 1300 sq ft. We will then calculate all the materials and application tools such as rollers, squeegees, mixers and spiked soles needed to do the job properly. We also provide you with enough epoxy for stripping included in the price. Sand is purchased by you locally and must be 00 type. This a four coat system consisting of Primer, Thin Build Ultra Epoxy, High Build Ultra Epoxy and then a final coat of our Ultra Wear Urethane Epoxy Topcoat. This is as heavy duty an epoxy floor as it gets and can be applied by in house staff! No special skills required and we provide complete instructions and unlimited tech support.
