Painted or Stained Cabinets in Austin Heat and Humidity

Four coats on a door at two hours of drying between each is most of a workday before the door ever goes back on its hinge. Austin, TX adds heat to that arithmetic, since summers with highs of 90 degrees or more on over 120 days a year set the surface skin of a coat while the paint underneath is still soft, as the notes at kitchen cabinets austin safety in construction show describe. A kitchen cabinet finish has to hold through all of it.
How wood moves

Hardwood doors expand across the grain in humid weeks, such as after rain off Lady Bird Lake, and shrink again in the dry stretch of August. A solid maple or oak rail-and-stile door moves a little at every joint. Paint across a joint will crack along that line unless the paint is flexible and the joint was glued tight.
Painted finishes

Paint on a shaker door hides grain and evens out color, and it covers a mix of materials: maple stiles with an mdf center panel look identical once sprayed. A catalyzed finish cures hard and resists grease, while a cheap latex coat can soften when wiped with a degreaser. Sheen matters too, since a satin or semi-gloss shows fewer fingerprints than flat and cleans easier.
Stained finishes
Stain shows the wood, so the species decides the result. Oak takes stain evenly and shows a bold grain. Maple and birch blotch, because the grain absorbs unevenly, and need a conditioner or a toned finish coat to look even. A raised panel door in stained oak hides small dents and wear better than the same door painted.
Heat and cooking
The doors beside a range see steam and grease every day. Thermofoil and melamine surfaces can lift or bubble near that heat, while a painted or stained wood door is repaired with a light sand and recoat. Yellowing on white paint comes from oil-based coatings and sunlight, and a window over the sink speeds it.
The odd freeze
A hard freeze about every other year rarely hurts interior cabinets. A vacant house with no heat is the exception, where moisture in a cold kitchen can lift a finish at an edge.
Refinishing existing doors, a sand and respray rather than a full replacement, is the usual route when the wood is sound and only the color is tired.
