RIGHt When the owner of a 100-year-old building in Greenville, Ga., needed a new floor for her restaurant, she did what many of us do: She went online and searched for a viable solution. moisture expected in any commercial kitchen: think sinks, stoves, and drinks. Things can get messy! The SI Linings crew got right to work by covering the walls and any room openings with painters plastic. They also used a large industrial blower in the doorway to create negative pressure in the space. "It's pulling air in the balance of the building so nothing can get out of the room," explained Puckett. Next up was to power-wash the floor to get a clean surface so that they could then focus on what was underneath. This would enable them to promote the adhesion between the thin pavers and the thin-set mortar, especially since screws tended to strip the pavers. Using a 5,000 psi (34,474 kPa) power-washer, it took the crew a few hours to push the paint off the octagon-shaped pavers. Once they were clean and dry, Puckett and his crew applied a thin-set mortar with a quarter-inch (0.64 cm) notch trowel across all 750 square feet (70 m²) of floor, which included the kitchen, refrigerator, and hallway. On top of the porter, they laid down quarter-inchthick (0.64 cm) Durock with about 25 to 30 screws per board. This locked everything in and stabilized the floor better than before. Over a few hours, the SI Linings crew applied primer on top of the Durock to make sure that the lining system was properly attached and to reduce pin-holing in the coating. They sprayed VersaFlex VF-20 using a Graco Airless sprayer to achieve 8 to 10 mils (203‒254 microns). Then they back-rolled the primer and waited around 6 hours before coming back in to put the topcoat on. With two guys spraying, including Puckett and his brother, and the other guys filling in on the supporting roles, they were on a roll. On this crew, everyone pitches in wherever they can to get the job done. HoldTight Solutions pioneered the concept of low-cost, easy-toachieve, and easy-to-measure contaminant-free surface preparation. Our HoldTight®102 salt remover and flash rush inhibitor prevents flash rust simply by removing surface contaminants. If there is NO FLASH RUST, there are NO CONTAMINANTS. Any "stuff" on the surface — chlorides, sulfates, nitrates, phosphates, shattered pieces of rust, abrasive, paint, or any other debris — will pull water to the surface and cause flash rust. And if you paint over any such stuff, sooner or later, it will pull moisture through the coating and cause coating failure. No flash rust = a clean surface. In other words, you know it when you see it! You don't need to use cumbersome, expensive, and applicator-sensitive field tests to prove it. This is a revolutionary old concept: make it simple and it works better. "102" is used in conjunction with dry-blasting, wet-abrasive blasting, and water-jetting ("UHP") blasting. It evaporates rapidly, lifting off moisture as it does, and leaves no residue. 102 is approved by most coating manufacturers for most coatings.
