Agree a working schedule with named dependencies, review points and a clear way to communicate changes.
First decide what the end date means
Board installed, finishing complete, accepted for primer and fully decorated are different milestones. Put the one you need into the request. If a move-in, cabinet installation or another booking depends on it, explain the dependency rather than describing every date as the final deadline.
| Milestone | Confirmation to request |
|---|---|
| Ready for board | Which preceding work, assessments and checks must be complete? |
| Finishing complete | Which surfaces, finish and review are included at this point? |
| Ready for the painter | Who confirms suitability for the selected coating system? |
| Ready for the next trade | Which rooms are released, and what protection remains? |
| Project closeout | Which touch-ups, cleaning and records remain after the main work? |
A gap between visits can be part of the work
USG's environmental guidance explains that joint-compound drying varies with temperature, relative humidity, application thickness and air exchange. Conditions can also differ between rooms. A generic overnight allowance should not be treated as proof that every surface is ready for its next treatment.

A product's working or setting time is not the total project duration. USG's Easy Sand document identifies those as product-specific intervals and sets separate requirements for decoration. Ask the contractor to follow the selected products' current instructions rather than turning a number on a bag into a painting appointment.

Build the schedule around dependencies
| Work item | Ready when… | Record |
|---|---|---|
| Site preparation | Access and agreed protection can be provided. | Owner; access window; room restrictions. |
| Board installation | The responsible lead releases the area for closing. | Required checks; release date; unresolved items. |
| Finishing visits | The specified previous treatment and site conditions permit the next step. | Planned visits; contractor's readiness check. |
| Surface review | The agreed review stage can take place. | Reviewer; rooms; outstanding observations. |
| Decorating or other follow-on work | The receiving trade accepts the defined handover. | Confirmed booking; protection; change contact. |
Keep a requested date, a provisional date and a confirmed booking distinct. If a prerequisite is unresolved, record who will confirm it and when. This is more useful than presenting every tentative appointment as a commitment.
Agree what happens when a date moves
- Name the person who receives schedule updates and can make decisions.
- Ask what notice is needed to change access or a visit.
- Identify bookings that rely on drywall being ready, including elevators and other trades.
- Record new work or concealed conditions before revising the finish date.
- Ask whether returning after another trade's work is included or requires a separate arrangement.
For example, if a plumbing change creates another opening, ask for an updated scope and the affected milestones. Keep the original completion target in the record, then agree the revised expectation. Avoid silently passing the delay to a painter who has not been notified.
Questions to settle before booking
- What does the proposed completion date include?
- How many work visits are anticipated, and what could alter that plan?
- Which checks or decisions could prevent the first visit from proceeding?
- Who confirms readiness before the painter or other trades arrive?
- How will schedule changes and any resulting cost changes be approved?
Langley: use the correct inspection process in the programme
Langley City and the Township have separate inspection processes; the Township does not guarantee next-day visits.

Ask the permit holder to use the process for the actual address and identify the checks that release each area. Keep any requested date provisional until confirmed. Board installation, compound readiness and the painter’s handover remain separate milestones whichever authority applies.
- Identify the authority and permit holder in the schedule rather than copying another Langley project’s booking process.
- Ask who communicates the inspection result and any conditions to the drywaller.
- Keep follow-on trades informed if a check, access arrangement or finishing-readiness assessment changes.
A few practical questions.
Can a small patch be finished in one visit?
Ask about the assessed repair, selected products, surrounding finish and intended handover. A small visible area does not establish the visit pattern; confirm the actual proposed visits with the contractor.
When should I book the painter?
Arrange the handover with both contractors. Use a provisional window until the responsible person confirms that the specified surface and conditions are ready for the selected coating system.
Is setting time the same as drying time?
No. Product working, setting and decoration requirements describe different stages. Follow the selected manufacturer's instructions and the contractor's assessment instead of using a setting-time label as a project countdown.
