Refinishing MDF thermofoil cabinets is a relatively straightforward process that can be done at home with a few simple steps. First, remove all hardware and clean the cabinets thoroughly. Next, sand the surface of the cabinets to remove any existing finish or imperfections. Apply a primer to ensure good adhesion, followed by several coats of paint or a new thermofoil finish. Allow each coat to dry completely before applying the next. Finally, reattach the hardware and enjoy your newly refinished cabinets. With proper preparation and attention to detail, you can achieve a professional-looking finish and extend the life of your MDF thermofoil cabinets.
Over time, the thermofoil coating on MDF cabinets and shelves can become dull and dirty. If the cabinets are still in good condition, repainting them can breathe new life into the room.
Before repainting, it’s important to properly prepare the slick surface of thermofoil-treated cabinets and shelves. By following the correct methods and using the right products, you can have a refreshed kitchen in just a day or two.
What is MDF?
Medium-density fiberboard, also known as MDF, is a versatile material with a smooth surface and durable qualities. It is commonly used for cabinetry, shelving, decorative trim, and other light carpentry projects. MDF is easy to cut, paint, and assemble.
However, the porous nature of MDF makes it difficult to paint directly. Thermofoil is often applied to provide a glossy, matte, flat, or beveled finish. Thermofoil is created by applying heat and pressure, and it is typically placed over bare MDF.
While thermofoil is easy to clean, it can crack, peel, or bubble when exposed to high heat and moisture. If you want to paint MDF shelves and cabinets covered in thermofoil, thorough preparation is necessary.
Preparing Thermofoil Cabinets
To refinish MDF kitchen cabinets, you’ll need to strip and clean them thoroughly. Use a strong cleaner, such as trisodium phosphate (TSP), to remove the glossy finish of the thermofoil and any soap or grease residue from the surfaces.
Take care to remove each door and drawer and label them for easier reassembly. Be cautious when handling large MDF panels as they are heavier than plywood and can swell if exposed to water.
Use medium-grit sandpaper to further remove the glossy finish and prepare the thermofoil for painting. This roughens the surface and helps the primer adhere to the MDF cabinets. Before painting, wipe down all surfaces with a damp cloth to remove dust.
Repainting MDF Cabinets
Apply a quality MDF primer spray or brush on a liquid primer to the sanded and cleaned thermofoil cabinet surfaces. This seals the porous MDF and creates a protective layer. The primer also enhances the adhesion of the paint and reduces the likelihood of chips and cracks. Follow the drying instructions provided by the manufacturer.
Use acrylic enamel or oil-based paint to apply a coat to the primed cabinets. Oil-based paints are preferred but can be more challenging to work with and have a strong odor. Waterborne acrylic enamel paint offers similar benefits to oil-based paint with less hassle. If applying two coats, allow the first coat to dry before applying the second.
