Cabinets have large flat surfaces at eye level. Any small defect will be very visible. The cabinets before painting need to be perfect or at least what you want. Any small scratches, dents or cracks will be there after painting – only the color changes.
At least was our experience. We had our cabinets sprayed with lacquer – the same kind of paint on your car. The guy took doors and sprayed those at his shop. He came into our house, hung plastic from the ceiling, walls, etc. and spray the boxes on the wall. The spraying took maybe 45 minutes. Plastic hanging hours.
I don’t know what cabinet paint is. I would go to a SherwinWin Williams store and ask them what they recommend for cabinets. We once painted bathroom cabinets with the highest grade of oil based paint. That paint was OK, but not as good as sprayed lacquer.
For sure insist on names of people whose cabinets were painted over a year ago – preferably two years ago. Look at those cabinets.
