The Post-Construction Painting Sequence GCs Expect

Post-construction painting looks simple from the outside: paint the walls before the building opens. In practice, it runs in at least two distinct passes, coordinates tightly with flooring and cabinet installation, and requires documentation that a lot of painting subs aren't ready to provide. Here is what GCs should expect from a painting sub on a commercial new-construction or major renovation project.

The two-pass structure

Pass one happens before other interior finishes go in. Primer and first coat on all new gypsum. Prime and paint on hollow metal (HM) frames. Prime and back-prime any carpentry that will be painted. This pass runs while the space is open — no flooring, no cabinets, no millwork installed yet — so the painting crew has full swing room and no masking burden.

Pass two is the finish and punch sequence. Final coat on walls and ceilings. Touch-up on frames and doors after they've been installed and hardware set. Back-prime carpentry and baseboard after cut-in. Trade-damage repair and punch list items — scuffs from other trades, frame dings, ceiling hits from equipment. Pass two can't start until the space is otherwise buttoned up enough that new paint won't immediately be damaged by other activity.

The sequencing rule that trips people up: cabinets before or after?

In areas where base cabinets will be installed, the sequence in well-run packages is: paint the walls behind the cabinets first, then cabinets arrive. If the painting crew comes back after cabinets to cut in behind them, productivity drops significantly and quality suffers. On a Portland-area GC package we reviewed, the spec and schedule were explicit: interior unit fit-outs had painting ahead of cabinet installation in each zone. That's the right sequence. Confirm it before the job starts.

Ceiling specs you need to read

Not all ceilings are just white flat paint. On some commercial projects — particularly buildings with energy or air-barrier requirements — ceiling coatings have spec sections of their own. We've seen Portland-area commercial projects where third-floor ceilings required a specific high-performance or elastomeric coating to satisfy the air-barrier spec in the ceiling assembly. Read the spec sections, not just the finish schedule. A painting sub who misses this creates a warranty problem at final inspection.

Exterior scope: siding, soffits, and the dry-season gate

Exterior painting on new construction — Hardie siding, soffits, trim — belongs in the April–August dry window if you're in Portland. Factory-primed Hardie panels are ready for a topcoat, but that topcoat needs dry ambient conditions for proper cure. Scheduling exterior painting in October in Portland and expecting it to hold is a gamble. The master schedule on a well-planned project reflects this: exterior paint lands in the dry window, not whenever the building is first enclosed.

Documentation: what a public or GC package needs

If the project has public funding or MBE/WBE participation requirements, the painting sub needs to be ready with a COBID certification, W-9, and COI at bid time — not as an afterthought. For prevailing-wage work, certified payroll records are a contract requirement, not optional. Strong Tower holds COBID 8404 and carries full documentation. We submit it as part of every formal bid package.

Trade-damage and punch allowances: price them separately

Every post-construction painting bid should include a separate line for trade-damage allowance and punch list allowance. Other trades damage paint surfaces — it happens on every project. If that repair time isn't priced as a separate allowance, it becomes a dispute at closeout. Price it clearly upfront, track it, and close it out with documentation.
