COATINGSPRO CONCRETE COVERED 2017 15 based on the size of the project because of how quick ly they cure. But now w ith the new product, contractors have double to triple the working time, allow ing them to tack le larger jobs w ithout sacrificing back-end cure time. Crews can be more efficient." T he EC-101 100 percent solids polyaspartic topcoat from Westcoat Specialty Coating Systems is another option that gives applicators a longer working w indow while dr y ing faster, enabling customers to utilize the space w ithin ~12 hours. T he EC-101 requires fewer coats w ith its high build, and it creates fewer bubbles due to its short dr y ing time, meaning it levels out smoothly and is ver y durable. " We wanted to help our installers when they have requests for jobs that need a fast turnaround," said Paul Kour y, president of Westcoat. T he Ser ies 256 ExcellaT hane from Tnemec, a modified a liphatic polyaspartic, is a separate possibilit y that prov ides a retur n-to-ser v ice time of about three hours for light traffic and about si x hours for full ser v ice, as well as low-temperature cure capabilities. A nother prov ider is Coatings for Industr y, Inc. (CFI), which offers a new, VOC-free system as part of its lineup, including the WearCOAT 2020 and 2035 as polyaspartic mid-coats and top coats, respectively. A s a system, not only do they offer same-day retur n to ser v ice, but the WearCOAT 2035 is specia lly for mulated to f low out f lat, v irtua lly eliminating roller marks, even though the product sets up fast. T his enables a quick retur n to ser v ice for clients. A long similar lines, the Flex coat polyurea floor coating from Rust-Oleum offers the flexibility of operating in a wide range of temperatures; it has the ability to go on multiple substrates, including concrete and wood, and it offers fewer environmental constraints. "It allows you to get back on the floor in two to four hours," said Rust-Oleum's Paine. outcome desired for the project, [contractors should] pick the right piece or several pieces of equipment to perform the work required at each stage," General Equipment's Wienczkowski said. "No one piece of equipment does it all." ough General Equipment does offer grinders, the company said it expects the market to trend in the direction of drier preparation techniques following the latest OSHA silica regulation. "As the new regulations go into effect, the one thing we do see is that more projects over time will switch to dry versus wet preparation techniques in order to eliminate the concrete slurry and clean up required during processes such as grinding," Wienczkowski said. "e switch will also be done in part to simplify and standardize the product needed from a preparation perspective in conjunction with dust collection systems, while at the same time meeting the silica dust requirements." Ancillary tools for the jobsite that may also need to be considered may include generators, dehumidifiers, and containment, as well as smaller tools, such as hand grinders, scrapers, ladders, and scaffolding. Finishing Touches With the surface prepared, contractors have an abundance of options when it comes to applying a new system. In some cases, only topical coating materials that form a resistant film, or membrane, on the surface may be necessary. On others, penetrating sealers may be used, either alone or in combination with coatings. e combination of coatings and sealants can protect the substrate from liquids and chemicals while providing superior abrasion resistance. ere are a number of directions contractors could go, including multi-coat systems with both primers and topcoats, but one characteristic is often most important of all: speed. "Every job is fast track," said Ball of Sherwin-Williams. "ey want products that get you in and out without sacrific- ing performance. at still drives a lot of what we do — how to speed up our products to allow for faster installation. Flooring is one of the last pieces that's installed, and unfortunately, you can't have anyone else in the area. ey can't do mechan- ical work or electrical, etc. So having products that allow that installation window to shrink is really advantageous. It just seems windows get tighter and tighter as time goes forward." One possibility could be the General Polymers GP4850 Polyaspartic Floor Coating SS from Sherwin-Williams, which is designed to meet the needs of those looking for a coating that dries fast for quick return to service but that also has a longer working time of 15 to 20 minutes and recoat window for increased application ease and flexibility. "Polyaspartics have become a lot more mainstream in the last five years," Ball said. "In the past, they've offered a quick return to ser vice, but you've been limited in scope Cementing Success There are many options when it comes to coating and other topping products for concrete, and many clients want it to be quick. "Every job is fast track," said Casey Ball of Sherwin-Williams.
