A painting bid looks simple from a distance: rooms, substrates, coats. It's rarely simple up close, because painting is the trade that sits at the end of every other trade's work — it prices the acceptance condition of a surface it didn't build, and it's often the section that quietly decides a dispute everyone assumes belongs to somebody else. The paint schedule tells you the systems. It doesn't tell you that the drywall finish-level fight actually gets settled by a clause sitting in your own section, or that a one-line note on the reflected ceiling plan just added a dry-fall coating requirement across an entire mechanical room's worth of exposed structure.
This is a working list of where painting scope actually gets decided, built from what shows up across real Canadian ICI tenders. Not a coatings catalogue — a list of the specific clauses worth hunting down before the number leaves the office.
What's reliably yours
- Surface preparation and painting per the specified systems — named systems per substrate, primer and finish coats, sheens and back-rolling requirements, for every scheduled surface interior and exterior. The named system is the price; two coats of the wrong product is not the same bid as two coats of the right one.
- Full preparation on surfaces being painted — filling, caulking, sanding, spot-priming, protection and masking, and cleanup. Prep is the actual bid; the visible coats are just the part that gets photographed.
- Field painting of exposed services where assigned — exposed structure, decks, railings, hollow metal doors and frames, and mechanical or electrical services in finished spaces. Extract exactly which of these the schedule assigns, since "exposed services" is a phrase that covers a huge range of actual square footage depending on the building.
- Touch-up after other trades — punch-list touch-up within the contract period, bounded by whatever acceptance language the documents actually state. This is a real, if usually small, obligation — and "within the contract period" is the part worth reading closely.
Where the fight actually happens
High-performance and special coatings
Epoxies, urethanes, elastomerics and dry-fall systems are real systems with real premiums over standard latex or alkyd — and on plenty of tenders they're carved out as a separate specialty bid under 09 96 rather than bundled into the general painting scope. Confirm which situation this tender is before pricing a high-performance system at standard labour rates, or before assuming it's excluded when it's actually sitting quietly inside your own section.
Intumescent and fire-retardant coatings
Intumescent coatings are usually specified under 07 81 or 09 96, and the trade that actually applies them is inconsistent — sometimes painting, sometimes carried by the steel erector or the fireproofing sub as part of their own package. This is a case where the product spec and the trade assignment live in different places entirely, and extracting one without the other tells you nothing about whether it's your line item.
Wallcovering installation
Wallcovering under Division 09 72 is sometimes packaged with painting and sometimes its own trade entirely, and there's no reliable default either way. This is a straightforward extraction question — does this tender's Division 09 72 sit inside your section or not — but it's an easy one to skip past on the assumption that "it's basically painting anyway."
The other half: what isn't yours, even when it looks close
- Substrate correction — drywall finishing defects, mill scale, or damaged surfaces belong to the substrate trade to correct. Painting's obligation begins at an accepted surface, which makes the acceptance criteria itself the real boundary, not the correction work.
- Shop-applied finishes — factory and shop coatings belong to the fabricator. Field touch-up of a shop finish is painting's scope only when the documents specifically assign it, not by default just because a scuff shows up on site.
Five things that hide outside the paint schedule
- Critical lighting and Level 5 language — worth repeating. Acceptance under wall-wash or raking light, and any accompanying skim-coat requirement, is the classic boundary dispute with drywall — and it's usually written in this trade's own section, not drywall's. Read your own documents for it before assuming the fight belongs to someone else.
- Dry-fall and exposed-structure requirements. Open-ceiling areas with a dry-fall system specified on deck, joists and services can represent enormous surface area hiding behind a single line on the reflected ceiling plan — a document most estimators aren't reading with painting in mind.
- Field-vs-shop finishing splits. Doors, frames and millwork each raise the same question — who primes, who finishes, and whose warranty applies — and specs assign it inconsistently across sections, sometimes differently for doors than for frames in the same opening.
- Environmental limits and VOC rules. Temperature and humidity windows, plus low-VOC product mandates, constrain both the schedule and the product choice — a winter interior finish schedule against a strict low-VOC requirement is a real scheduling conversation, not boilerplate.
- The paint schedule itself, read per substrate. Systems, coat counts and sheens vary by substrate and room, and accent walls or an unusually high colour count multiply mobilizations rather than gallons — a detail that a square-footage takeoff alone won't surface.
Who you're actually sharing the ceiling with
| Trade | What to reconcile before you price |
|---|---|
| Drywall | Finish-level acceptance before primer — a flaw that telegraphs through paint lands on whichever trade the acceptance language actually names. Extract it rather than assume. |
| Flooring | Sequence with base and finished floors, and protection responsibilities running each way during adjacent work. |
| Mechanical & electrical | Exposed services in finished areas — painted by this trade or supplied prefinished, per the schedule, not by default. |
| Door supplier | Hollow metal and wood doors: the shop-prime versus field-finish boundary, and whose warranty covers the finish either way. |
The pass that catches most of this
Read your own section for the critical-lighting and Level 5 clause before assuming that fight belongs to drywall — it's usually written in painting's own documents. Then read the reflected ceiling plan specifically for dry-fall and exposed-structure notes, and check the field-vs-shop finish split for every opening and casework item rather than assuming one answer covers all of them. The paint schedule tells you the systems; the clauses scattered around it are what decide whether the bid actually matches what gets built.
