Assumptions

• Ceilings are clean, dry, sound, and ready for painting.
• Allowance includes standard surface preparation and two coats of paint.
• Existing painted surfaces are sound and suitable for direct repainting following normal preparation.

Risk flags

• Poor ceiling condition, staining, high ceilings, or specialist finishes may increase labour and material requirements.
• Unsuitable or highly porous surfaces may require additional preparation after inspection.
• Final material cost depends on colour choice, coverage rates, and selected paint brand.
