Choose the finish before work starts, with the final paint and room lighting in mind.
A short guide to Levels 0–5
The six-level summary below is checked against the accessible GA-214-2021 reference. The publisher now lists GA-214-2026; its complete technical PDF has not been reviewed for this guide.

| Level | What the distinction means |
|---|---|
| 0 | No joint finishing. The final decorative treatment may not yet be selected. |
| 1 | Tape embedded at joints and interior angles; generally concealed areas. |
| 2 | Embedded tape with a thin compound covering; fasteners and accessories receive one coat. Used where the specified treatment does not prioritise appearance. |
| 3 | Additional joint treatment for specified medium/heavy textures—not a smooth painted finish. |
| 4 | Further joint and fastener treatment for specified flat-paint and other suitable finishes. |
| 5 | Level 4 treatment plus a skim coat across the entire surface; relevant to demanding paint and light conditions. |

The Level 4 / Level 5 decision
CertainTeed explains how variations between board paper and treated joints can become more apparent under reflective paint or light travelling across the wall. A whole-surface skim coat helps provide a more uniform surface. This is why sheen and strong side lighting belong in the finishing conversation—not just in the paint conversation later.

- Show the contractor where large windows and wall-washing lights will be.
- Share the planned paint colour and sheen, even if they are provisional.
- Identify long, uninterrupted walls and ceilings that matter visually.
- Ask which surfaces the proposed finish covers, rather than applying a vague upgrade to the whole project.
Use a sample to agree the appearance
For a visually demanding room, ask the designer and contractor whether an agreed sample area would make the decision clearer. Record which wall it represents, the intended coating, the lighting and who accepts it.
A finish designation alone does not settle every appearance question. Put the final decorating scope and acceptance approach in the project documents so the drywaller and painter are working toward the same outcome.
Finishing and painting are separate scope decisions
| Ask about | What to write down |
|---|---|
| Joint finishing | The agreed level and exactly which surfaces it applies to. |
| Whole-surface work | Whether a skim coat is included and the boundaries of that work. |
| Primer & paint | The responsible trade, products and handover condition. |
| Review & touch-ups | When the surface is reviewed and how later damage is handled. |
Specify appearance separately from the approved work
For a property under City of Delta jurisdiction, the building guidance ties inspections to the approved permit and plans. Keep those construction requirements with the project brief, then describe the intended decorative finish separately. An agreed sample under the room’s final light can clarify blending and sheen without suggesting that the City guarantees a particular cosmetic result.

- Mark the surfaces to be retained and the boundaries of any skim or broader blend area.
- Agree the coating and representative light for appearance review.
- Name separate owners for the applicable construction release and the painter handover.
A few practical questions.
Does every room need Level 5?
No. The decorative finish, light, surface and project requirements guide that choice. Discuss the room as it will actually be used and decorated; a higher number should answer a specific appearance requirement.
Is Level 5 the same as a perfectly flat wall?
No. A finishing designation describes treatment of the surface. It is not a promise that the underlying framing or completed surface is mathematically flat. Discuss the expected appearance and any underlying irregularities separately.
