For a typical 2,500–3,500 sq ft new construction home — prime coat, two finish coats on walls and ceilings, two coats on trim — interior painting takes approximately 5–10 working days depending on crew size, number of colors, ceiling height, and trim complexity. Homes with extensive custom millwork, multiple accent walls, or cabinet painting add time. Utah’s dry air speeds dry times between coats, but recoat windows must still be respected for inter-coat adhesion. RainFire Builders provides a painting-specific schedule as part of the overall project timeline.
