sanding wooden panels

Painting any wood is one thing, and painting wood panelling is another. Doing so requires preparation, which is a vital part of the whole process. This involves sanding both solid-wood planks and wood sheet, sanding them for any cracks or gaps, and priming the surfaces for dark lines and knots. Once done, the wood panelling is ready for the actual painting with a standard roller and brush.

If you are unsure of how to perform these tasks, follow the steps below:

Step 1: Sanding

Sanding the wood panelling is the first step in the process. Sanding is required for two important reasons: (1) it scratches the glossy finish of the wood so that the primer can grip to it, (2) it smoothens out rough spots that might show through the paint job. Before starting, wear a suitable dust mask or respirator, so that you don’t inhale the sanding dust. Follow the simple steps below:

  • If the surfaces are smooth, sand your wood panelling with 180- or 220-grit sandpaper.
  • If they’re rough and need some knocking down, use 150-grit paper instead.
  • Remove all the sanding dust from the wood using a rag or a vacuum with a brush attachment.

Step 2: Caulking or Spackling

The next step is caulking. It’s important to know that wood plank does expand and contract due to seasonal humidity changes. The process of caulking is necessary as well for two reasons: (1) to ensure that joints between the planks won’t develop hairline cracks, (2) to prevent the finished paint wood from having dark lines from any gaps if the planks aren’t fit together. Follow the steps below for caulking:

  • Use a high-quality paintable caulk.
  • Apply it with a fine bead, and smooth it along the plank joints with your finger. Make sure it’s invisible once it’s painted. You can caulk either before or after priming.

Step 3: Priming

The third step is priming. Priming is a critical part of the whole process. Not only does it prepare the old, dry wood for paint, it also helps hide dark lines (common on sheet panelling) and knots (common with solid-wood planks). Take note of the following:

  • Use a stain-blocking primer. For serious cases, use shellac-based primer seals for wood planks with knots, oils, smoke, crayon, and others.
  • First, apply primer to the dark lines or plank joints using a brush.
  • Cut in along all edges of the panelling with a brush.
  • Then, use a brush or standard paint roller to prime the remaining surfaces.
  • Let the primer dry completely.

Step 4: Painting

The final step is painting. Once the wood panelling has been prepared and primed, paint the interior. You may choose a sheen based on how flat or glossy you want it to look or how durable and washable you want it to be. Follow the steps below:

  • Apply the paint by cutting in with a brush, then rolling or brushing the remaining areas.
  • Try a 1/2-inch- or 5/8-inch-nap roller cover, and tip the roller slightly to get it into the panel grooves or joints.
  • If the paint drips or collects in the grooves, back-brush them (brush after rolling).

The preparation steps are as important as the painting of the wood panelling itself. Follow the steps outlined above, and your wood panels may turn out the way you imagined. These wood panels will surely augment your home’s interior designs and its overall appearance.
