Laminate and melamine are common finish surfaces for many countertops, cabinets, and shelves, but these plastic materials are known for being susceptible to wear—not to mention becoming quickly outdated. They tend to get scratched and nicked with normal use, and many countertops have a burn mark or two. And unlike homogeneous solid-surface materials, such as Corian or butcher-block wood—both of which can be effectively sanded down smooth and brought back to like-new condition—laminate and melamine are composed of multiple layers that should not be sanded through. But you can do the next best thing: resurface the laminate or melamine with a quality paint job.

Prepare the Surface

Unlike wood, laminate and melamine cannot be sanded down to a natural grain—because they have no natural grain. With wood, exposing the grain is vital for the paint to adhere to. Laminate and melamine are designed to repel kitchen spills, like food, oil, and water, so they naturally repel paint, also.

For this reason, it's vital that you properly prepare the surface so that the paint will stick over the long term. Improperly applied paint will peel off of laminate and melamine, creating a bigger mess than you started out with. The key is to degloss and roughen the plastic surface of laminate and melamine, and to use the right paint or coating products. Some paints call for apply for a primer coat before applying the paint; others can be used without primer.

Choosing the Right Paint

When painting laminate or melamine counters, instead of using ordinary paint, you might want to purchase an all-in-one countertop resurfacing system, such as Rust-Oleum's Countertop Transformations. These kits are formulated for the rigors of countertops by laying down a thick topcoat that is securely adhered to a bonding primer coat.

These systems are markedly different from paint-only processes in that they include a layer of solid decorative chips. The chips are dispensed from a hand-cranked spreader, much like an outdoor spreader that you use to disperse grass seed. These chips lay down a thick coat that is far thicker than paint. One advantage of this thick layer is that it effectively covers up all scratches.

Alternatively, you can use a urethane-reinforced acrylic paint, such as INSL-X Cabinet Coat. While more expensive than the ordinary acrylic-latex paints you would use on drywall, the urethane-reinforced products have better hiding abilities and will stick better to problem surfaces. Cabinet Coat is designed to adhere to plastic, metal, and urethane surfaces without a primer, but laminate and melamine surfaces should be sanded before painting.

A third option is to apply a 100 percent acrylic, flash-bond primer, such as XIM (Rust-Oleum), Bullseye 1-2-3 (Zinnser), or Fresh Start (Benjamin Moore), followed by two coats of satin or semi-gloss enamel paint and two coats of clear acrylic sealer.

What You'll Need

Equipment / Tools

  • Box fan
  • Dust mask or respirator
  • Work light
  • Paint roller with dense-foam roller cover
  • Synthetic-bristle paintbrush

Materials

  • Drop cloths
  • Painter's tape
  • Contractor's paper
  • Plastic sheeting
  • 150- or 180-grit sandpaper
  • Tack cloth
  • Clean, lint-free cloths
  • Mineral spirits
  • Primer (if necessary)
  • Paint

Instructions

  1. Prepare the Area

    Remove all items near to the cabinets or counters to a garage or a covered patio. Open up the windows. If desired, set up a box fan so it blows out of one window, to promote cross-ventilation through the work area. Place drop cloths on the flooring and tape contractor's paper or plastic on all surfaces that will not be receiving the coating. Confine the work area with plastic sheeting to prevent sanding dust from traveling throughout the house.

  2. Roughen up the Surface

    Protect yourself from sanding dust with a dust mask or respirator. Sand down the laminate or melamine surface with 150- or 180-grit sandpaper. Using a work light, check frequently to make sure that you are bringing down all glossy surfaces to a matte (or flat) finish. Do not sand down too hard or you risk damaging the thin wear layer of the laminate or melamine.

  3. Clean the Surface

    Wipe down the surface with a tack cloth, using light pressure to prevent transferring the wax from the cloth to the surface. Follow by wiping down the surface with mineral spirits and clean, lint-free cloths. Let the surface dry completely.

  4. Apply the First Coat

    Apply a thin coat of paint (or primer, if the paint you're using calls for it) to the entire surface, using a paintbrush for the edges and tight spots and a roller with a high-density foam roller cover (designed for smooth surfaces) for the flat areas. Take special care to maintain a wet edge while painting: Overlap the edge of each painted section with fresh primer or paint before the previously painted edge dries. Allow the first coat to dry for at least 6 hours or as recommended by the manufacturer.

    Note: You can passively ventilate the work area, if desired, during the initial drying process for any of the paint coats, but do not use fans, which can pull airborne dust and debris onto the wet paint. Ventilate with open windows only if there is no air disturbance or strong drafts in the work area. Also, make sure the temperature and humidity levels in the work area stay within the manufacturer's recommended ranges. In general, odor from drying or curing coatings is strongest while the coating is still wet.

  5. Apply the Subsequent Coats

    Apply one or more additional coats of paint, using the same techniques. Let each coat dry as directed. If you are using standard enamel paint, the last one or two coats can be layers of clear acrylic sealer. It's not uncommon to apply as many as four or five coats in total: a primer coat to begin, then two coats of enamel paint, finishing with one or two coats of acrylic sealer.

  6. Cure the Surface

    Let the final coat cure fully for two to three weeks before placing any heavy objects on it or scrubbing the surface vigorously. You do not need to ventilate the area during this period. In the meantime, you can use the surface gently and clean it only with a damp cloth. Letting the paint cure fully before using the surface as usual will help prevent small appliances and stored items from sticking to the paint or marring the finish.
