Why is my paint chipping? Inside a house, it’s usually because the paint never bonded to the surface underneath. In the Macomb and Oakland County homes we paint, the most common causes are latex brushed over old oil-based trim enamel, glossy or greasy surfaces that weren’t sanded and primed, and doors, cabinets or railings used before the paint had hardened.

This is about paint on trim, doors, cabinets, railings and walls inside your home. Every cause below comes with a job our crews fixed.

Why Is My Paint Chipping? Match the Spot to the Cause

Where the paint is chipping tells us most of the story before we open a can:

Where Usual cause Quick check
Trim, doors Latex over oil Alcohol test
Cabinets Grease, no sanding Chips at edges
Rails, shelves Used too soon Soft or tacky
Walls Glue, gloss, grime What’s under the chip

What We Find Under Chipping Trim: Latex Over Old Oil

Paint chipping off trim in an older Macomb home usually comes down to one thing. Decades ago, trim and doors got a hard, glossy oil enamel. Years later someone brushed latex over it without sanding or priming, and latex can’t grip a slick oil surface. It sits on top like a sticker, and the first bump from a vacuum or a shoe knocks it off.

The baseboards above in Utica, MI show exactly that. The homeowner noticed chips popping off every time the vacuum or the cat’s toys bumped the trim, just a few months after the last repaint. Look at the chips: under the white is a shiny golden-yellow coat that never let the newer paint hold.

To confirm it, we ran the rubbing alcohol test, and you can do it at home:

  1. Find a spot where the old coat shows, or a hidden corner of the trim.
  2. Wipe it clean, then rub hard with a cotton ball soaked in rubbing alcohol.
  3. If color comes off on the cotton or the paint goes soft, it’s latex. If nothing happens, it’s oil.

The cotton on this job came away clean. Oil.

Touching up the chips would only add another coat that can’t grip. Instead, the crew removed the loose paint back to a firm edge, scuff-sanded the oil to dull its shine, and primed.

How We Fix Cabinets That Chip at the Edges

Cabinets carry years of cooking grease and hand oils, and most come from the factory with a slick finish. Paint over that without degreasing and scuff-sanding, and it has nothing to hold on to. Edges and the area around handles go first because that’s where hands, rings and pots hit every day.

The green cabinets below were painted 3 years before the homeowner called us. The homeowner had brushed them on as a weekend DIY project and noticed chips showing up. The chips run along the door edge, the frame corner and right under the pull, and the brush marks show they were hand-painted. Underneath, the original honey oak factory finish was showing through.

The crew degreased every surface, sanded the failing paint back, and primed. The finish is Sherwin-Williams Emerald Urethane Trim Enamel, a hard-curing enamel, which is what the best paint for cabinets has to be in a working kitchen.

If your cabinet paint is chipping only at the edges, the rest of the door is likely close behind. Patching the corners won’t fix a bond that failed everywhere.

Dry Isn’t Cured: What We Tell Homeowners About Railings, Shelves and Doors

Paint that’s dry to the touch can still be soft underneath. Most enamels feel dry within hours but need days, sometimes weeks, to harden fully. Grip a rail, set books on a shelf or shut a door against its stop before then, and the soft film dents, sticks or pulls away.

The stair rail below in Shelby Township chipped within a few weeks of a repaint. The family was back to grabbing it the very next morning, kids heading off to school with backpacks, long before the paint had a chance to cure. The chips sit right where hands grab the rail on the way up, and the brown showing through is the rail’s original stained finish.

When we paint a rail, a door or a shelf, I’d rather you wait an extra few days than call us back to redo it.

What We Find Under Walls That Chip

Wall paint rarely chips on its own. When it does, something under it is stopping the bond: wallpaper glue left behind after the paper came off, an old glossy finish nobody dulled, or kitchen grease that was painted straight over. Another coat won’t help, because it sticks to the same problem layer.

How We Stop Paint Chipping (and When to Call a Pro)

Knowing how to stop paint chipping comes down to fixing the bond, not adding paint. This is the order our crews work in:

  1. Remove loose paint back to a firm, well-stuck edge.
  2. Clean off grease, dust and residue.
  3. Scuff-sand glossy surfaces so the primer has something to grab.
  4. Prime with a bonding primer over oil, varnish, factory finishes or bare spots.
  5. Finish with the right enamel and sheen for the surface: semi-gloss or satin for trim, cabinet enamel for cabinets.
  6. Give it time to cure before daily wear.

Call a pro when chips keep spreading, when the alcohol test comes back oil across a whole room of trim, or when the house is old enough that lead is a real possibility. That’s the point where interior painting in Macomb County done with lead-safe prep makes more sense than another coat that won’t hold.

FAQ

Can I just touch up chipped paint?

Only if the paint around the chip is still firmly stuck. Press tape on it and pull: if more paint comes off, a touch-up will chip again. Fixing the bond first is how to stop paint chipping for good.

How long before I can use freshly painted cabinets, doors or railings?

Wait for 24 hours. Light use is fine sooner than heavy use, and anything that rubs or bumps should wait the longest.

Is chipping paint dangerous in an older home?

It can be. The EPA’s numbers on how likely older homes are to have lead paint put it at about one in four homes built from 1960 to 1977, rising to nearly nine in ten built before 1940. Chips and dust from worn doors, sills and stairs are the main concern, so test before you scrape or sand.
