Etobicoke Retail Shell: Commercial Boarding, Level 4 Finish & ProMar Seal
Taking over after 1&Co completed the structural framing, our crew handled the complete drywall boarding, taping, compounding, and priming scope across complex corridor runs, bulkheads, and masonry openings. After hanging and trimming the gypsum panels, we embedded paper tape and corner beads along every transition. To build strong, low-shrinkage seams with optimal workability, we ran two fill coats using a custom blend of CGC Sheetrock 90 setting-type drywall compound and ready-mixed all-purpose compound (Red Box), topped with a tight skim coat of machine-grade finishing compound (Yellow Box). Surfaces were machine- and pole-sanded under work lighting, interior corners were detailed with paintable acrylic caulk, and the entire substrate was sealed with Sherwin-Williams ProMar 200 Primer and point-up touch-ups for a dead-flat, paint-ready handoff.
