HOW TO PAINT PANELLING
With the right prep work, you can transform your old panelling and achieve a beautiful new look.
Step #1: Assess
Before you start, take the time to determine what type of panelling you have. Polyurethane finish, layers of paint, and even a decades-long coating of cleaning products can mask the material underneath. Find a spot where a panel’s edge is exposed, which may require removing an HVAC grate or baseboard moulding, to properly examine the end of a piece of panelling to see what you’re working with. If your panelling is veneer (which only has a thin surface layer of wood grain), fibreboard, or composite instead of solid wood, you want to be very careful not to damage it.
Veneer is a paper-thin layer of wood grain over a stronger—though unsightly—material like particle board or fibreboard. Be careful not to sand through it.
Step #2: Clean
Grease, grime, and even cleaning-product residue can really build up on veneer or hardwood panelling over the years, which can then prevent your paint from properly adhering to the surface. Be sure to remove all contaminants and residue with a grease-removing cleaner before beginning work. If the panelling is still too glossy after cleaning, you may need to dull the surface a bit with a light sanding to make sure the paint has texture it can adhere to. Just be very careful if you’re dealing with veneer, as sanding can ruin the thin outer layer, exposing the fibreboard underneath.
Whenever you’re removing an old surface through sanding, it’s important to protect yourself from potentially dangerous dust with a mask and goggles.
Step #3: Spot Prime
Do you want the finished look to be that of a smooth wall? Or will you retain the look of the panelled grooves? If you want to keep the grooves, skip to Step 4.
To get the best-looking smooth surface on your painted panelling, check out the video on this page. You’ll need to prime the panelling first—at least the areas you plan to fill with spackle or caulk—to ensure you get the best possible adhesion. Primer choices include:
- For laminate or veneer panelling, INSL-X® Stix® primer, specifically engineered to bond with challenging glossy surfaces, will give you the best results.
- For hardwood panelling, INSL-X® Aqua Lock® or Fresh Start® High-Hiding Primer, K046 will both provide better stain blocking for real wood, with very good adhesion.
- For tannin-rich woods like cedar or redwood, your best option is to use an oil-based primer such as INSL-X® Prime Lock or Fresh Start® Multi-Purpose Oil-Based Primer, F024.
Step #4: Spackle and Caulk
If you are creating a smooth surface, wait until after the first coat of primer has dried before you spackle to get proper adhesion. You will need to use joint compound (also called drywall mud) or spackle to fill in all the grooves in the panelling to meet the rest of the surface. Using a quick-drying “hot mud” or patch, which has a high pH level, creates unique challenges and is not recommended. If you do use it, be sure to use a 100% acrylic primer for best results.
Whether you’re going for a smooth or grooved look, any seams between panels also need to be filled in. For this, you should use caulk instead of spackle. Caulk will expand as the panels shift slightly over time, as opposed to spackle, which can crack.
Helpful TipSpackle or joint compound dries hard, whereas caulk can expand and contract slightly over time. This makes spackle better for filling grooves and caulk the better option for seams.
Step #5: Sand, Vacuum, and Tack
A light sanding at this stage will create a smooth, dull surface free of imperfections, and also one that is just rough enough to give the paint proper adhesion. Using a fine sandpaper (220 grit is a good level here), focus on any areas that are uneven or that have dried drips, such as corners and edges. After you sand, be sure to vacuum the panelling thoroughly and tack or wipe everything down with a damp cloth to remove any remaining dust. Then let it dry.
Step #6: Prime Again
Re-priming after spackling and caulking is one of the most important things you can do to ensure an even, professional finish. A second coat of primer will help conceal differences between the spackle and panel surfaces, cover any stains and knots in the panelling, and provide proper adhesion for your paint top coat. Be sure to give the primer enough time to fully dry as recommended on the label.
Step #7: Paint
Use a paintbrush to cut in to corners and edges first, then blend any seams as you complete the rest of the wall with a roller. Note that a lighter paint colour on dark wood may require an extra coat, depending on how well the primer masked the grain below.
Different Paints Offer a Range of Finish Options
Waterborne alkyds like Benjamin Moore ADVANCE® offer an easy-application top coat for painting panelling and cure to a durable, furniture-quality finish. Latex paints will give you more of a glossy or shiny look: Benjamin Moore’s AURA® Interior and REGAL® Select Interior paints both offer rich, durable colour with a mildew-resistant finish.
Benjamin Moore offers 3,500+ different colours from which to choose, and pint-sized paint colour samples are available for shipping right to your door to make decision-making easier.
Step #8: Paint a Second Coat
After the first coat of paint is fully dry, apply a second coat for an even, spot-free finish. Be sure to allow a full 24 hours of drying time for the new finish to fully cure before replacing any wall decor, fixtures or furniture.
