What's best paint to use to paint my kitchen cabinets??

Stick with a time-tested paint like Sherwin Williams, or my fav, Behr.

Which ever paint you go with, keep this in mind. If you truly love your kitchen, take the time to take the doors off the hinges and the knobs/handles off the doors. If for some reason you can't, just use an artists brush and put some petroleum jelly on the metal pieces. The paint won't stick.

Make sure they are clean and dry. Use acrylic latex paint. Remove the doors and hardware. Mark the doors and cabinets with tape where they go. Lightly sand the doors and cabinets to remove any gloss and roughen the surface for paint. Prime with a stain blocking primer like Zinsser 123, KILZ,or BIN. Then paint with your color. Seal with at least three coats with a water based polyurethane. Use a small foam roller and foam brush for a smooth finish.

the best paint to apply to any cabinet doors etc. is Mel mean paints comes in what ever color you want its the hardest and very durable bear makes a good one lots of elastic in bear paints to make them as durable as they are so does Sherwin Williams sheckset time that's your key the longer it takes to set up the better it is

good Luck
