10 Painting Mistakes That Lead to Peeling, Uneven Color, and Callbacks

Most painting failures show up within two years. Almost all were preventable.

Where painting jobs go wrong

Painting complaints cluster around a few predictable failures: poor coverage, visible brush marks, peeling at trim, and uneven sheen. Most trace back to one of three things: rushed prep, cheap paint, or one coat instead of two. None of these problems are obvious on day one.

The 10 pitfalls

Skipping surface washing

Paint does not adhere to dirty surfaces.

Not priming new drywall or bare wood

New drywall has a porous paper face that absorbs paint unevenly.

Only one coat of finish paint

One coat saves the painter time and you money on paper.

Cheap or diluted paint

Some painters dilute paint with water to make it go further.

Masking tape left on too long

Masking tape should be removed while the paint is still slightly tacky.

Not caulking trim before painting

The gap between wall and trim, between trim pieces, and between trim and ceiling needs to be caulked before painting.

Painting over peeling or cracked paint without scraping

New paint over old peeling paint will peel too, and sooner.

Using the wrong sheen for the room

Flat paint in a bathroom or kitchen will not clean and will show every scuff.

Paying in full before the job is done

Painters who have been paid in full have no incentive to come back and fix drips, missed spots, or uneven coverage.

No touch-up paint left behind

Without leftover paint, touching up scuffs later means matching color at the paint store.

The short version

Ask about prep. Confirm prime and two coats. Get the paint product in writing. Hold back payment until you have approved the final walkthrough. Those four things eliminate most painting complaints.
