How to Handle the Grooves When Painting Wood Paneling

If you’re looking to update your wood paneling without removing it, filling in the grooves can help achieve a smooth, modern look. Here’s a step-by-step guide to tackle the grooves and paint your paneling:

Step-by-Step Instructions:

1. Fill the Grooves with Joint Compound
   To make the paneling look more like drywall, you need to fill in the grooves with joint compound (drywall mud). Use a quality compound like USG joint compound and apply it with a putty knife.
   • Tip: Apply at least two coats, sanding between each to ensure a smooth surface.
2. Sand the Entire Wall
   After the joint compound has dried, sand the wall with fine-grit sandpaper (180-220 grit).
   • Why: Sanding helps level the joint mud and scuff the paneling, which allows paint and primer to adhere better and prevents chipping.
   • Tip: Wipe down the wall with a damp sponge to remove dust before proceeding.
3. Prime and Paint
   Apply a high-quality bonding primer to the wall. For the best results, use an oil-based primer, although a stain-blocking latex primer is a good alternative if you want a less smelly and easier-to-clean option.
   • Tip: Two coats of primer are ideal, especially if you’re painting a lighter color over dark paneling.
   • Next: Once primed, paint the wall with your desired color. For a smooth finish, using a paint sprayer works best, though a brush or roller can also be used.

Alternative Approach

If the grooves aren’t a major issue for you, or you want to keep some retro charm, you can skip the joint compound step. Simply clean, prime, and paint the paneling for a refreshed look without covering the grooves.

Considerations

While filling the grooves can create a drywall-like finish, it’s labor-intensive for DIYers. If you’re not sure about the effort, replacing the paneling might offer a quicker and better result. Additionally, paneling has been making a comeback as an accent wall in modern designs, so you might not want to eliminate the grooves entirely!
