You can make your kitchen cabinets look better than new. A coat of alkyd paint will do wonders.
For preparation, remove all the cabinet doors, and take off the hardware. Gently sand them down with a fine grade sandpaper to remove grease and dirt build-up. Set them aside. Repeat the sanding around the frame areas of the cabinets.
Paint the frames first. Keep in mind it will take at least 8 – 12 hours for the alkyd paint to dry completely. Lay the cabinet doors flat on a drop cloth or newspaper. Paint one side at a time. Flat doors can be rolled with a smooth roller sleeve. After they are dry, replace the hardware and hinges and re-hang the doors. This is an inexpensive way to spruce up the kitchen.
If you are changing colors, you may need more than one coat.
There are alkyd and latex products made specifically for cabinet refinishing. You may want to choose one of them.
Semi-gloss is the recommended finish for cabinets.
