How to prepare wood paneling for painting

Are you tired of looking at the same old wood paneling in your house? Well, you can always spice it up with a fresh coat of paint. The whole task is quick and easy, making it a simple home project to pick up. But as is the case with all DIYs, proper preparation is important.

If you’re wondering how to prepare your wood paneling for painting, this step-by-step guide will tell you all that you need to do:

Step 1: Clean Your Wood Paneling: 
Cleaning is the first step to any paint job.  Most dust and grime can be removed using a moist rag. If there are multiple layers of dirt, remove them all with a solution of TSP (trisodium phosphate, a heavy-duty cleaner) or a TSP alternative (which can be less harmful) and water. 

Painting over a dirty surface will result in paint that does not stick properly. It will also appear low-grade because the paint will take in clumps of dirt, making a clean look impossible. 

Step 2: Fill and Sand the Wood:
Fill any gaps or cracks with wood putty and allow them to cure or harden with a putty knife. Lightly sand all the paneling, trim, and moldings with 150-grit sandpaper if required. 

The goal is to remove the gloss and create a light, grainy surface on which to apply the paint. 
Avoid sanding too hard. When you're done, wipe it down with a moist towel to remove any remaining dust.

While sanding isn’t essential, it improves adhesion. Alternatively, you can use a good primer that will stick to the old surface finish. Contact your paint supplier to know the right primer for your paneling.

Step 3: Take Care of the Trim:
Caulk any gaps between the planks of the paneling, between the panels and the trim, and around the windows and doors. 

If you wish to keep the color of the trim the same or paint it a different shade than your wood paneling, remove the trim from the wall using a pry bar.
For the baseboards, if you want them the same color as the wall, lightly sand the nearby wood trim to allow the paint to adhere. After you've sanded everything, wipe down the walls and trim with a clean, wet cloth to eliminate any dust or particles. 

Step 4: Caulk the Cracks and Protect Surrounding Areas: 
Apply caulk to any cracks and gaps where the paneling meets the baseboard and ceiling, as well as around doors and windows, with a caulk gun. This will give your room a polished appearance. Before painting wood paneling, let the caulking dry completely. To know how long you should let it cure, consult the manufacturer's directions.   

While painting wood paneling, ensure that your room is clean. A tip is to use drop cloths large enough to cover the paneled walls and the floor. It protects your flooring if the paint drips. Painter's tape can be used to mask any areas you want to cover, such as vents, doorways, or windows. The last thing you need is an extra clean-up job after your painting is done.  

Step 5: Prime the Wood:
Apply a thin coat of primer to the paneling with a foam sponge roller and a brush, or just a brush alone. When rolling, keep a brush handy to clean any drips from cracks, seams, or corners that the roller can't reach. Ensure that the entire surface is covered, including any trim. 

It's ideal to use a stain-blocking primer that's either oil-based or water-based. These will prevent grease or wood stains from penetrating and destroying your paint job. We recommend using a tinted primer with a colorant that matches the finished paint for even coverage. Once the primer is done, apply two more coats of latex wall paint. 

Step 6: Paint the Paneling:
Before painting the wood paneling, figure out how much paint you need. Paint all the surfaces with a thin coat of paint. Begin at the top and work your way down, ensuring all spaces between the panels are filled. Remove excess paint that has collected in the panel grooves with your brush. Take care of any drips as soon as possible. Allow the first coat to dry completely before applying the second.

Your wall may appear done after the primer and first coat, but a second coat will ensure the best coverage and longevity. It's well worth the extra effort and resources.  

Step 7: Paint the Trim:
Paint the trim in the color of your choice. It's ideal to go with a glossier finish for the walls since it makes the trim stand out and creates a smooth, easy-to-clean surface.  

Now that you know how to prepare wood paneling for painting, try these simple tips to get a smooth paint finish. 
  • Use Brushes and Rollers: While rollers help you reach larger surface areas, brushes work complementary to them. Brushes help you access corners and edges easily. 
  • Primers are Essential: Primers are designed to adhere to problem surfaces, providing a smooth and consistent surface for the paint to stick to. Flashing is a problem in which sections of the finished paintwork appear to be painted with distinct paint glosses. Primer helps prevent this. A primed surface leads to a well-finished, smooth paint job. 
  • Consider Paint Additives and Tints: If you paint for too long, paint can become tacky and cause brush-drag. You have the option of picking up the pace or purchasing an addition that might lengthen your working time. Penetrol and Floetrol are two often used chemicals for creating smooth brush strokes. 
Painting near a fan or heating vent, or in direct sunshine, will speed up the drying process and result in tacky paint. Tinted primers are your hack to adding more dimension to your paint job.  

That’s it! We told you that the process is quick and easy. 
So now that you know how to prepare wood paneling for painting, it's time to get your hands dirty and give your panels a new look!
