How to Seal Bamboo
- 1). Equip a power sander with 60-grit sandpaper. Remove the natural outer silica coating, using the power sander. Sand in the direction of the wood grain until the bamboo appears dull.
- 2). Exchange the 60-grit sandpaper with 100-grit. Sand the bamboo until it feels smooth.
- 3). Wipe the bamboo surface with tack cloths; this is critical as sawdust will interfere with the application process.
- 4). Add a stained finish now if you want to. Apply gel stain to the bamboo, using a china brush; wipe the wet gel from the surface, using rags. Let the stained finish dry for three hours. Wash the brush, using fresh mineral spirits. Skip this step if you do not desire a stained finish
- 5). Apply a solvent-based wood sealer to the bamboo, using the china brush. Wood sealers tend to sag on vertical bamboo surfaces. If you notice this, smooth the sagging areas with the brush. Let the sealer dry for two hours. Apply another coat.
- 6). Use varnish on bamboo wood furniture.
