How to fill a dent in my sauna wood.

For minor dents, applying water can effectively raise the compressed wood fibers, making them flush with the surrounding surface. You can use a spray bottle or a damp paper towel. Here are the detailed steps :

1. Apply Water: Saturate the dented area with tap water, either by spraying or dabbing with a wet towel. Allow the water to penetrate until the wood begins to swell and the dent rises. You may need to reapply water if the wood does not raise sufficiently initially.
2. Sand with 220 Grit: Once the dent is raised, lightly sand the area with 220-grit sandpaper (hand sanding) until it is level with the rest of the panel.
3. Finish with 320 Grit: Follow up with 320-grit sandpaper (hand sanding) to smooth the area and achieve a finished look.
