Painting particle board can be a real trial. After all, most paint simply will not stick to the stuff. However, with the proper preparation, painting your particle board kitchen cabinets will be just as easy as painting anything else in your house. You will need to add a few extra steps, but the results will be well worth it when the paint sticks to the particle board rather than sliding down to the floor.
Remove all of the hardware from the kitchen cabinets. This will keep you from getting paint on the handles and having to constantly wipe things off as you paint. Put the hardware in a location that will be easy for you to find later.
Sand the cabinets. Sanding the cabinets will help the primer bond better, so you must do at least a cursory "roughing up" of the cabinets to get them ready for the priming and painting process.
Prime the cabinets. Apply at least two coats of primer to the cabinets. It is better to go light on the primer and add more coats than to use too much primer and create a blobby mess. Make sure you prime all parts of the cabinet including the sides and bottoms to make sure there is a good surface for your paint. Let the primer dry between coats. This can take 20 minutes to two hours.
Paint your cabinets. As with the primer, go light on the paint. Use a thin, even coat and plan to apply more until you get the look you want. Let the coats of paint dry between layers, and make sure the paint is sticking before you put more on. If the paint is not sticking, wait until it dries, sand it off, apply more primer and give it another try.
Replace the cabinet hardware. Once the cabinets are completely dry, screw the handles back onto the cabinets.
