Quick answer
Bathroom painting in Naperville, IL uses a moisture- and mildew-resistant paint over cleaned, repaired and primed surfaces, usually satin on walls and a moisture-resistant flat on the ceiling. A typical bathroom is a one- to two-day job, depending on repairs and drying time.
The job
Bathrooms fail paint faster than any other room
Steam condenses on cool walls and ceilings, soap and hairspray film the surface, and mildew grows in corners the fan does not clear. Ordinary wall paint blisters and peels there.
We clean off film and mildew, scrape and patch peeling areas, recaulk split joints, prime and paint two coats of a moisture-resistant finish. The fan gets checked while we are there, since a weak fan is behind most bathroom paint failures.

What this job covers
A
Moisture-resistant wall painting
Bathroom walls get a paint made for humidity, usually in satin, which resists moisture and cleans easily. Before it goes on, the walls are washed to remove soap and hairspray film, glossy areas are sanded, and any patches are primed. We cut in carefully along tile, tub and vanity edges and around mirrors and fixtures, and apply two full coats. The room then needs to stay dry, with the shower unused, for about a day while the paint cures and hardens.
B
Mildew cleanup and sealing
Gray or black spots in corners and on the ceiling above the shower are mildew, and painting over it without cleaning only hides it for a few weeks. We clean it with a mildew wash, rinse and let the surface dry, then seal the stains with a stain-blocking primer before the finish coats. Split caulk around the tub, shower and sink is cut out and replaced with a mildew-resistant caulk. If mildew keeps returning from behind tile, we point that out rather than painting over it.
C
Bathroom ceiling and trim
Bathroom ceilings take the most steam, so peeling usually starts there, often in a ring around the shower. We scrape loose paint to a firm edge, skim and sand the edges flat, prime and paint the ceiling with a moisture-resistant flat. Door and window trim and the baseboard behind the toilet get a hard enamel that wipes clean. Doors are painted on both faces and the bottom edge, which is often left bare and swells in the humidity if it is skipped.

Around Naperville
Bathrooms here deal with two seasons of trouble: humid summers, when walls barely dry between showers, and furnace-dry winters, when cold outside walls collect condensation. Both push moisture into the paint film. That is why every bathroom we paint gets a moisture-resistant product, why we check that the exhaust fan actually moves air, and why families are asked to keep the shower off for about a day after the last coat.

A moisture- and mildew-resistant paint, usually satin on walls and a moisture-resistant flat on the ceiling.
Steam condenses there. Weak ventilation, soap film and ordinary paint make it worse.
Not until it is cleaned and sealed. Paint over mildew lets it come back through.
Usually about a day, while the paint cures.
