46 JANUARY 2018 COATINGSPROMAG.COM masterpiece marred by golden swirl marks, the crew made their second pass with 60/80-grit heads. e second pass took less time than the first, but cleanup was a royal pain in the neck! "It was raining the entire time we were grinding, and water was coming into the building because there was a whole glass wall missing," Seay said. "We always try to clean as we grind, but as soon as we cleaned, other trades would track in mud. On Tuesday, I talked with Doug Smith about it, and he really came through by giving us the entire building ursday and Friday. at would also give the epoxy and urethane sealers the entire weekend to cure. It looked like we had a break between rain storms, but we needed to keep our fingers crossed." Wednesday afternoon, the crew used a Clarke Encore automatic floor scrubber to suck up the dirt. e ride-on scrub- ber works like a miniature Zamboni ice-surfacing machine used at skating rinks. Water shoots out in front, scrubbing pads attack the dirt, and a squeegee removes the water. Seay estimated that the scrubber pulled up 90 percent of the dirt, so DCV followed up by running an 18-inch (45.7 cm) Clarke floor buffer with black stripping pad (dry). ey went behind the buffer with a DeWalt 10-gallon (37.9 L) HEPA (high-efficiency particulate air) filter vacuum to pull out any remaining dust. e DCV crew likes that the DeWalt's auto-cleaning function cleans the HEPA filter every 30 seconds, which keeps the vacuum drawing. Before knocking off for the night, the crew overfilled all concrete joints with dark brown Metzger/McGuire RS-88 polyurea caulk, let it dry for about an hour, and trimmed the joints flush with razor blades. Dry State Bright and early ursday morning, the DCV crew began mixing Increte Systems' Vibra Stain. e dye comes in 8-ounce (236.6 mL) bottles and is typically mixed at one bottle per gallon (3.8 L) of water. A lcohol may be substituted for water to promote faster drying, according to the manufacturer's technical data sheet, but for those needing an even speedier cure, there's an option that doesn't appear on the data sheet. "Acetone can be used as a carrier," said Scott Lowe, Increte technical manager. "In a business in which people need things done yesterday, it's helpful because it dries very quickly. You can seal coat it almost immediately." Wielding a B & G Equipment hand-pump Concrete Acetone The DCV crew installed a Ballast Point logo in the middle of the entry way to the restaurant. They used a stencil, dye, and topcoat to get that down right. The crew wore rubber boots, a 3M respirator, gloves, and glasses as needed throughout the project. And when applying the dye, the crew made sure that the building had the right ventilation. Several layers of coatings had to be applied to seal the stain: National Polymers 015 epoxy primer and National Polymers 521 topcoat (mixed with aggregate), which were both applied by rollers and brushes. "It's incredible!" DCV Co-Owner Landon Blanks said. "As soon as you walk in, the Ballast Point logo is right there, and the floor's soft color tones sort of move you throughout the building."
