Can you paint kitchen cabinets instead of replacing them?
Usually yes, and it costs a fraction of a new kitchen. It works well on timber, MDF and most factory-finished doors. It works poorly on anything with a peeling or bubbling laminate face, because paint will not re-bond a laminate that has already let go.
The result depends almost entirely on preparation. Degreasing, a thorough sand and an adhesion primer are the difference between a kitchen that still looks right in three years and one that chips at the handles in three months.
Doors are best done off their hinges and laid flat where there is room, which is slower but avoids runs on a vertical face. Expect the kitchen to be partly out of action while it happens.
What paint should I use in a bathroom?
A kitchen and bathroom formulation on both the ceiling and the walls, in a low sheen or semi-gloss rather than a flat. Those products carry more mould resistance and a tighter film that copes with condensation and with being wiped down.
Sheen matters more than most people expect. A flat finish in a bathroom holds moisture and marks the moment anyone cleans it, which is why bathroom ceilings in flat white are the surface that fails first in most Canberra homes.
Trims, door frames and the back of the door take an enamel, since they are touched constantly and need to wash rather than scuff.
Why does the paint in my bathroom keep peeling?
Almost always moisture behind the film rather than a bad tin of paint. The usual causes are an exhaust fan that is undersized, ducted into the roof cavity instead of outside, or simply not run long enough after a shower. Repainting without fixing that buys you about a year.
The second cause is painting over a surface that was never sealed or was still damp. New render, patched plaster and previously mouldy areas all need treating first, and mould needs killing rather than covering.
Three things worth checking before you repaint anything: does the fan vent outside the building, does it run for fifteen minutes after the shower, and does the window get opened. If all three answers are no, the paint is not the problem.
