When Level 5 is the right call
Specify Level 5 when the wall or ceiling will be painted in eggshell, satin, semi-gloss, or gloss; when raking or grazing light will hit it (entryways, stairwells, long hallways with end-glazing); or when wall covering is being eliminated. Level 4 — three coats over tape, no skim — is fine for flat paint and most textured surfaces. Anything more demanding needs Level 5.
How we deliver it
After Level 4 finishing, we apply a thin skim coat across the entire surface — not just over fasteners and joints — sand it flat, and inspect under 500-watt halogen at a raking angle. Spot-skim and re-sand until the surface reads uniform. Primer-sealer is part of the scope (paint-grade compounds can flash through latex primers). The bid line is per square foot of board, written.
Schedule and dependencies
Plan Level 5 work after MEP rough-in passes inspection, before flooring and trim are set, with HVAC running for ambient humidity control. Typical residential Level 5 sequence adds 3–5 working days over a Level 4 schedule on the same square footage; for hospitality build-outs we coordinate Level 5 around the painter's primer schedule so the skim coat is fresh when the topcoat goes on.
