For wood, brushing is fine, but you may want to hire a professional for a good finish. Using a roller to paint cabinets is a lot faster than brush painting, however, the fabric on the roller will create a 'bobbly' texture on the surface. The texture a roller puts on cabinets makes it unsuitable for gloss paint.
In short, the best type of roller for painting cabinets is a 4-inch roller with a foam cover or, in some cases, a fabric cover with a thin nap. A 4-inch roller is best because it allows you to control paint application in tight spaces and navigate around the trim, curves, and grooves inherent in cabinet designs.
Using a paint sprayer is one of the easiest ways to get a super smooth finish on your cabinets. By their very nature, paint sprayers eliminate brush strokes and roller marks completely. And painting with a paint sprayer is almost always faster than using a paint roller and paint brush.
Walls, Wood, and Metal - Small 1/4″ nap roller covers or foam rollers will produce the smoothest finish. Light to Medium Textured Surfaces - Microfiber rollers are best.
Roller marks, which painters sometimes call "holidays," are a routine hazard when painting with a roller, and there are many ways to avoid them. When you notice holidays after the paint has dried, you can usually make them disappear by applying another coat after sanding lightly—if necessary—to remove drips and humps.
To apply flat, eggshell, or satin paints and stains, a knit roller cover is recommended. Knit roller covers can pick up and release higher amounts of paint than woven fabrics because the fibers have a looped backing with a single pass-through process resulting in a more “open” fabric.
3/16 to 1/4-inch thickness is perfect for smooth surface roller covers for painting metal doors, interior doors, trim and cabinets. They work well with semi-gloss or gloss coatings and both oil- and water-base enamels. 3/8 to 1/2-inch thickness is preferable for semi-smooth surfaces such as drywall.
Try to limit brush marks by painting with the grain of the wood. While on the trim boards, using the foam roller and brush paint only one side of drawers and doors. Next, using the same brush and foam roller apply a coat of Cabinet Enamel to the base cabinets. DRY OVERNIGHT and clean your brush.
My favorite sealer for painted furniture is General Finishes High Performance Top Coat and this would also be my first choice for sealing cabinets. It is water-based, non-yellowing, and extremely easy to work with (unlike many other sealers).
Two coats of paint are essential for cabinets—you're building a surface. By the way, to get the nicest finish, use a brush, a 2- to 2 1/2-inch fine bristle brush. Whatever paint you use, ventilate the room—direct a fan out the window—and wear the masks they sell in paint stores.
Detailed Patterns, Warped or Damaged Cabinets
If your cabinets have detailed patterns or they are warped, chipped, cracked or have other damage to them, then painting your kitchen cabinets is not the way to go – it most definitely won't solve your cabinet problem.
If your cabinets are stained, apply at least two coats of quality primer. For me, there's nothing better than BIN, Zinsser's shellac-based pigmented primer. It dries fast and flat, without brush marks (unlike most oil-based primers). You can buy it at home and hardware stores, as well as online (view on Amazon).
Each roller has a different thickness of fabric or “nap”, specifically designed for different surfaces around the home. The thicker the nap or length of fabric, the more paint a roller will hold. The thicker the nap, the rougher the surface the roller is designed for.
POSSIBLE CAUSE
Shaking a partially filled can of paint or using too high of a speed when using a drill mixer. Excessive brushing or rolling – applying a paint too rapidly – will drive excess air into the film. Use of a roller cover with wrong nap length.
Foam rollers tend to last a shorter period of time than traditional rollers. They are excellent tools for a painter who does not perform painting jobs on a routine basis. If you are someone who only paints a room every few years, foam rollers are ideal for you.
Woven roller covers are more shed-resistant, so they're better for gloss and semi-gloss finishes, which can highlight lint left over from the roller. For flat, eggshell, and satin finishes, knit roller covers do the job more efficiently. For consistent control and smooth finish, we recommend microfiber roller covers.
Wool or mohair: Natural materials are the best choice for oil-based paints, as they will help apply paint smoothly and with full coverage on your walls. Synthetic: Rollers made of synthetic materials, like nylon or polyester, are very durable and resistant to shedding.
Again, generally speaking, the rougher the surface of the wall the longer the hair on the sleeve. A long sleeved mohair roller would be used to cover a textured wall or an artexed ceiling whereas a smooth foam roller would be used to paint emulsion on a nice smooth, plastered wall.
