COATINGSPRO MAY 2017 47 coating to effectively "seal " the mortar. en, after several weeks away to make room for the other subcontractors, Cook 's crew would return in August for the final two weeks of the project, which consisted of the application of the intermediate coat and topcoat. By phasing the job in such a manner, this meant that those upper coats would be unblem- ished and in peak condition when Fontainebleau opened the new hangars to clients. "If we had waited until the end to do everything, it would 've taken four additional weeks for the client before they could open for revenue," Cook explained. "Staging the work helped them gain four weeks, because there was availability in those hangars, and we took advantage of it. e owner's repre- sentative loved our flexibility." Ground Control With the two-part schedule agreed upon, Cook and his PPI crew of approximately 12 workers started the first phase of work in early June with an emphasis on surface preparation. Each JOB AT A GLANCE PROJECT: Install a showcase concrete floor with resistance to chemicals, tire stains, and high impact on two connecting hangars at a private airport COATINGS CONTRACTOR: PPI Epoxy Coatings LLC 9535 Satellite Blvd., Ste. 100 Orlando, FL 32837 (855) 774-3566 SIZE OF CONTRACTOR: ~15 employees SIZE OF CREW: ~12 crew members PRIME CLIENT: Fontainebleau Aviation 14200 NW 42nd Ave. Opa-Locka, FL 33054 (305) 685-4646 SUBSTRATE: Concrete CONDITION OF SUBSTRATE: New construction; good but high moisture SIZE OF JOB: ~70,000 sq. ft.

MATERIALS/PROCESSES: » Prepared surface with grinders from Diamatic and Substrate Technology, Inc. and shot blasters from BW Manufacturing and Blastrac » Cleaned prep work with vacuums from Ruwac and Pullman Ermator » Applied vapor barrier from KOSTER at ~15 mils (381.0 microns) » Installed Flowprime primer at ~10 mils (254.0 microns) » Trowel applied Flowtex epoxy floor mortar at ¼ inch (0.6 cm) » Sealed with Flowcoat OP at 16-20 mils (406.4-508.0 microns) » Installed two coats of Flowcoat SF41 at 14-16 mils (355.6-406.4 microns) each » Applied two coats of Flowseal PU Gloss topcoat to the interiors at 5-6 mils (127.0-152.4 microns) each coat; the first coat was pigmented and the final coat was clear » Applied Flowseal PU Satin to the perimeter at 10-12 mils (254.0-304.8 microns) SAFETY CONSIDERATIONS: » Wore 3M disposable respirators when working on surface preparation » Wore glasses, gloves, steel-toed boots, safety vests, and hard hats during certain phases To save time and allow other subcontractors to work on the jobsite, the PPI crew worked the hangars in two phases.
