Will Painted Cabinets Peel or Chip?
Whether a painted finish lasts comes down to the coating and the prep underneath it. We finish in 2K polyurethane — a factory-grade, two-component catalyzed system — over meticulous prep. Here is what actually determines how a cabinet finish holds up.
The Coating We Use on Cabinets
We finish in 2K polyurethane — a factory-grade, two-component catalyzed cabinet coating. The resin and a hardener cross-link as they cure into a hard, smooth film.
Kitchen cabinets are a demanding environment: they get grabbed, bumped, splashed, steamed, and exposed to grease and cleaning chemicals every day. That is why we spray a catalyzed 2K film over thorough prep — and why we back every cabinet job with a 5-year written warranty.

What Determines Whether a Cabinet Finish Lasts
1. Film Hardness
Cabinet edges, drawer fronts, and areas around handles see the most daily contact, so film hardness matters most there. The catalyzed cure of 2K polyurethane builds a harder film than air-dried cabinet paint, which is the whole point of using a two-component system on the surfaces hands touch every day.
2. Adhesion and Prep
If the surface is not properly sanded, deglossed, and primed, the bond starts out weak regardless of which coating goes on top. Thorough prep is what gives any finish a sound foundation.
3. Moisture
Cabinets near sinks, dishwashers, and stoves are exposed to steam and water. Moisture is a common cause of adhesion loss in any cabinet finish, which is why under-sink cabinets and the cabinets directly above a stovetop place the highest demands on the coating and the prep beneath it.
4. Heat
Cabinets near the stove, oven, and toaster see the most sustained heat in the kitchen. A fully cured, catalyzed 2K film and proper bonding prep are what give the finish on those surfaces a sound foundation.
5. Grease and Chemicals
Kitchen surfaces meet grease, cooking oils, and cleaning products — including ammonia and bleach — every day. A cured, catalyzed 2K polyurethane film is formulated to resist routine kitchen cleaning, which is why we use it on surfaces that get wiped down constantly.
The 2K Polyurethane System We Use on Cabinets
We finish in 2K polyurethane — a factory-grade two-component catalyzed coating, sprayed with HVLP equipment in two primer coats and two to three topcoats and sanded with 220 after the first primer coat and surface corrections, 320 after the second primer coat, 320 or 400 after the first topcoat, and 400 to 600 only before a third topcoat when needed. It is the cabinet system we trust for demanding residential kitchens.
Because the film is catalyzed rather than air-dried, it cures to a hard, smooth surface built to take the steam, heat, grease, dish impacts, and routine cleaning a working kitchen throws at it day after day. That is the reason we spray a 2K system instead of ordinary cabinet paint — and the reason we can back the work with a 5-year written warranty.
The Role of Proper Preparation
Even the best coating system will fail if applied to a poorly prepared surface. Our prep process is designed to give the 2K polyurethane the best possible foundation:
- 1.Degrease. Every cabinet surface is thoroughly cleaned with professional degreasing agents to remove years of kitchen grease, cooking oils, and silicone residue from cleaning products. Grease contamination is the hidden killer of adhesion.
- 2.Sand. All surfaces are sanded to create a consistent mechanical profile. This gives the primer maximum surface area to grip. On previously finished cabinets, sanding also removes any deteriorated or contaminated old finish.
- 3.Fill. On oak and other open-grain woods where you want the pores filled and the finish smooth to the touch, Tyler sands hard, works a high-build 2K primer into the grain, and skim-fills the flat panels smooth. Without this step, the wood grain telegraphs through the topcoat. The gentle waves in the wood still show in the light, and small profiles can keep a little grain texture; he'll show you where before work starts.
- 4.Prime. After surface corrections, Tyler sands with 220 grit, applies the second coat of high-build 2K primer, and sands with 320 grit before topcoats.
- 5.Topcoat. Two to three topcoats of 2K polyurethane are sprayed with professional HVLP equipment over two primer coats. Surfaces are sanded with 220 after the first primer coat and surface corrections, 320 after the second primer coat, 320 or 400 after the first topcoat, and 400 to 600 only before a third topcoat when needed for maximum inter-coat adhesion. The final result is a smooth, multi-coat bonded finish.
What If Your Cabinets Are Already Peeling?
If you are reading this because your cabinets are already peeling or chipping, you are not alone. This is one of the most common calls we get. A previous painter used the wrong product, or a DIY paint job is falling apart, and now the cabinets look worse than before they were painted.
The good news: we can fix it. The failed paint must be completely removed — we strip, sand, and prep the surface back to bare wood or sound substrate. From there, we rebuild the finish system from scratch using our standard 2K polyurethane process. Starting from sound substrate with proper prep gives the new finish a durable foundation.
Important note: cabinets with peeling paint require more prep work than cabinets with an intact original finish, which does affect pricing. But fixing a failed paint job with the right coating system is still typically less than replacing the cabinets entirely.
