What is the best approach to painting wood panelling in an older New Brunswick home?

Painting over wood panelling is entirely doable and can dramatically modernize an older New Brunswick home — the key is thorough cleaning, the right primer, and accepting that the grooves between panels will still be visible unless you fill them.

Wood panelling was a go-to wall finish in NB homes from the 1950s through the 1980s, and it's extremely common in basement rec rooms, living rooms, and bedrooms of homes built in those decades. The good news: painting it is a legitimate, cost-effective alternative to removing it. The bad news: shortcuts will show up immediately — either as paint that peels within a year, or as bleed-through from tannins and resin in the wood.

Cleaning and prep is the make-or-break step. Panelling collects grease, smoke residue, dust, and cleaning product buildup over the years. Wipe it down thoroughly with a TSP (trisodium phosphate) solution or a strong degreaser like Krud Kutter. Let it dry completely — at least 24 hours. Then sand the panelling lightly (120-150 grit) to degloss the factory finish. The old finish is often a varnish or lacquer that paint won't bond to without scuffing it first. Don't skip this step, especially in NB where older panelling often has a very hard factory sheen.

The right primer is critical. Many NB homeowners paint panelling and then watch it peel, discolour, or show bleed-through within months. The culprit is almost always using a wall paint directly, or even a standard latex primer, on wood that's high in tannins (cedar, pine, fir) or that has old oil-based finish on it. Use a shellac-based stain-blocking primer like Zinsser BIN (about 0-65/gallon) or an oil-based primer for the first coat. These bond to previously finished surfaces and block tannins and knots from bleeding through your topcoat. A quality latex topcoat goes on top with no issues. One full coat of shellac primer + two coats of latex wall paint is the reliable sequence.

Decide how to handle the grooves. The V-grooves between panels are what give the space that dated panelling look. If you want to minimize them, fill each groove with paintable latex caulk or lightweight spackling compound, smooth it flat with a putty knife, let it dry, then sand smooth before priming. This is tedious work but transforms the result — you'll still see a faint line in strong raking light, but from normal viewing distance the wall reads as smooth. If you're less concerned about the grooves, skip the filling and embrace the texture — it can actually look quite charming painted in a deep navy or forest green.

NB-specific consideration: In older homes in Saint John's North End, Moncton's Elmwood area, or Fredericton's Skyline Acres, basement panelling often has moisture issues lurking behind it from older foundations without proper drainage. If you notice any soft spots, discolouration, or musty smell, address the moisture source before painting — paint won't fix the underlying problem and will peel within a season. Check for moisture with a meter; wood should be below 15% before painting.

For a typical basement rec room with panelled walls (roughly 60-80 linear feet), expect to spend 50-250 on materials (primer, paint, caulk, sandpaper). A professional painter in NB will typically quote 00-1,800 for the full job including prep, priming, filling grooves, and two finish coats. This is a project many determined DIYers tackle successfully — but the prep work takes longer than the painting itself.
