Slick factory surfaces take paint only over a waterborne bonding primer, which is the difference between a finish that holds and one that peels. Cabinet painting on these materials starts with the primer decision, not the colour.
Kitchens put in between about 2005 and 2015 across Patterson, Carrville and the later Vellore Village streets are mostly MDF-core thermofoil, and melamine boxes and interiors are near-universal in condos and rental units throughout the city.
Slick Surfaces Reject Ordinary Cabinet Painting Primer
Thermofoil, melamine and high-pressure laminate all leave the factory sealed and non-porous, built to resist the one thing paint needs, which is absorption. Ordinary primer rests on the surface and lifts off with the tape. A waterborne bonding primer grips them chemically instead, reaching full adhesion after three or four days.
So cabinet painting on these doors begins with a hard scuff sand to break the sheen, a thorough degrease, then the bonding primer, then two or three sprayed topcoats. The bonding primer is not a stain blocker, so where there is water staining or a bleed risk underneath, a shellac coat goes on first.
Peeling Thermofoil Is Beyond Any Cabinet Painting
Paint cannot glue vinyl film back onto the board under it. A door where the thermofoil has bubbled or lifted, which almost always happens at the bottom rail beside the dishwasher or next to a wall oven, keeps lifting after painting, and the new finish tears along with the film.
Those doors have two honest options. Heat will take the film off back to bare MDF, after which the door primes and sprays like any other MDF door. Otherwise the door is replaced and finished to match its neighbours. Stripping costs labour, replacement costs a door, and both get priced on the quote so the comparison is plain. The cabinet refacing and door replacement page covers the replacement route.
Melamine Edges Chip, So Cabinet Painting Seals Them First
Melamine is a paper-thin surface over particleboard, and its weak point is the edge. Chips at door corners and along drawer fronts expose the board, which then swells the first time it meets water. Those edges get filled and sanded smooth before the bonding primer goes on.
Boxes and interiors in melamine can be painted for the same reasons, though interiors carry their own price, since they add genuine labour to something hidden behind a closed door. Where the melamine has already swollen from a leak, paint fixes nothing and the cabinet painting quote will say so.
Condo And Rental Kitchens Are Where This Cabinet Painting Happens Most
Units around the Vaughan Metropolitan Centre and along Highway 7 were finished recently enough that oak never entered the picture. Thermofoil doors and melamine boxes are the standard, which makes bonding primer the standard too, and the small door counts keep these jobs at the lower end of the price range.
Landlords repainting between tenants and owners preparing a unit for sale both use this work for the same reason: a galley kitchen can be sprayed for a fraction of what replacement costs. Building rules, elevator bookings and the logistics involved are covered on the condo kitchen cabinet painting page.
Have Thermofoil Or Melamine Doors Checked Before Deciding
Whether a door is a candidate takes about a minute to establish in person, and the answer is not always yes.

The rest of the cabinet painting services offered across Vaughan and Concord are listed on the Vaughan Cabinet Painting home page.
Bonding primer is what makes cabinet painting stick to a factory surface, and knowing when a door is past saving is what keeps the rest of the kitchen from being wasted.
Thermofoil, Melamine and Laminate Cabinet Painting Questions
Will paint stick to thermofoil?
Yes, over a waterborne bonding primer. Ordinary primer rests on the surface and lifts off with the tape. The door gets a hard scuff sand, a thorough degrease, the bonding primer, then two or three sprayed topcoats. Full adhesion takes three or four days.
What happens to doors that are already peeling?
Paint cannot glue vinyl film back onto the board under it. Heat removes the film back to bare MDF, and the door then primes and sprays like any other MDF door. Otherwise the door is replaced and finished to match. Both routes are priced on the quote.
Can melamine boxes and interiors be painted?
Yes, once chipped edges are filled and sanded smooth and a bonding primer goes on. Interiors carry their own price because they add real labour. If the melamine has already swollen from a leak, paint fixes nothing and the quote will say so.
