What Happens During an Exterior Repaint, Day by Day

Most homeowners have never watched an exterior repaint from start to finish, and the schedule can feel opaque from the inside. Here is what a typical Salt Lake City exterior project looks like, day by day, on a medium-sized home in reasonable condition.

Before day one

The quote is signed, colors are confirmed, and, if you are in an HOA community, the color scheme is approved in writing. On your side, the perimeter gets cleared: patio furniture moved, plantings trimmed back from the walls, vehicles parked away from the house.

Day one: wash

The whole exterior gets washed to remove dust, chalk, pollen, cobwebs, and organic growth. In this valley, chalk removal is the important part, since paint applied over chalk bonds to powder rather than the wall.

Nothing gets painted on wash day. Surfaces need to dry, which in Salt Lake’s dry air usually means overnight rather than several days.

Days two and three: prep

This is the longest and least visible phase, and the one that decides how long the result lasts.

Failed paint is scraped back to sound edges. Those edges are sanded and feathered so the transitions do not telegraph through the new coat. Bare wood gets spot-primed, with stain-blocking primer where cedar or redwood will bleed. Caulk joints, window and door perimeters, trim returns, siding butt joints, are cut out where they have failed and renewed with a flexible product that survives freeze-thaw cycling.

On pre-1978 homes, which is most of Salt Lake City proper, this phase runs under lead-safe practices: plastic containment on the ground, controlled sanding, and HEPA cleanup at the end of each day.

You will notice the house looks worse at the end of prep than it did at the start. That is normal and it is a good sign.

Day four: masking and first coat

Windows, roofing, concrete, light fixtures, and plantings get masked and covered. Then the first finish coat goes on, usually sprayed and back-rolled or brushed where the surface texture demands it.

In summer, crews follow the shade around the house rather than working straight through in full sun, since paint applied to a wall at 130 degrees dries before it can level and bond. Expect the sequence to look odd from inside: east side in the morning, west side late in the afternoon.

Day five: second coat and trim

Second finish coat on the body, then trim, fascia, soffits, and doors, which are brushwork rather than spray and take proportionally longer than their surface area suggests. Multi-color schemes add time here for cut lines and drying sequence.

Day six: detail, cleanup, walk-around

Masking comes off, cut lines are checked and touched, fixtures are reinstalled, and the site is cleaned. Then the walk-around: you and the crew lead go around the house together, and anything that needs attention gets marked and addressed before the job is called complete.

Where the schedule flexes

Weather. Salt Lake City is dry, roughly 15 to 16 inches of precipitation a year, so rain delays are less common here than most markets. The exception is the late-summer monsoon pattern, when a clear morning turns into a heavy afternoon burst and costs half a day.

Heat. Extreme heat compresses the workable hours on sun-facing elevations and can stretch a five-day job to six.

Discovery. Soft wood behind a fascia board or a rotted sill corner turns up during scraping. Standard practice is to stop, show you, and issue a written change order before the extra work happens.

What homeowners need to do

Very little once the perimeter is clear. Keep windows closed on wash and coat days for the elevations being worked, keep pets inside during work hours, and be available for the final walk-around. Living in the house throughout is normal.
