Left Different areas (kitchen, mechanical, and operating rooms) called for different Dur-A-Flex flooring solutions. The kitchens received Poly-Crete MDB system with Flintshot aggregate broadcast to rejection followed by two pigmented top coats of Poly-Crete KT, squeegeed and back rolled. Job at a Glance Project: Install floor coating systems in new build regional medical center in New York contractor: "Our products were less than 10g/liter," Sacks recalls. "I made recommendations to HBE for proper flooring systems for each specific environment." CEI's three distinct projects — mechanical rooms, a large kitchen, and operating rooms with seclusion areas — called for three different floor coatings systems. The mechanical rooms would be tackled first. The CEI crew would install Dur-A-Flex's Elast-O-Coat Waterproofing Membrane followed by their Shop Floor System, which is a combination of pigmented Dur-A-Glaze Shop Floor, a 100-percent solids epoxy, and Flintshot natural quartz sand. The Shop Floor System would receive Armor Top, an aliphatic urethane topcoat. The kitchen first received Poly-Crete MDB system, a 100 percent solids aromatic cementitious urethane. The crew broadcast Flintshot aggregate to rejection and followed that with two pigmented top coats of Poly-Crete KT, flat squeegeed and back rolled. Operating rooms and seclusion areas received Dur-A-Gard SL self-leveling pigmented epoxy and Dur-A-Chip flooring system, a decorative poured-in-place flooring with colorfast chips in the epoxy. These were followed by Dur-A-Glaze #4 with water clear hardener and Dur-A-Glaze #5, a polyaspartic topcoat.
