Cutin from the surface of kawayan tinik (Bambusa blumeana) twigs and branches was chemically removed by boiling samples in disodium octaborate tetrahydrate (DOT) and slake lime at 5, 10 and 15 percent concentrations for 30 and 60 min. Treated samples were applied with nitrocellulose (NC) lacquer and paint to evaluate their finishing adhesion performance and hot-and-cold check resistance following ASTM D1211-60 methods. Kawayan tinik twigs and branches treated with 5 percent DOT at 30 min boiling exhibited high finishing adhesion when NC lacquer was applied with one coat of sanding sealer. The hot-and cold-check test showed that NC lacquer and paint rated high in all the three indices of finishing serviceability: appearance, integrity and protection. Removing cutin by boiling for 30 min in 5 percent DOT cost USD 0.0094 less per piece of 60-cm long bamboo twigs and branches than manual processing. The used solution can be left to evaporate and the sediments buried in a pit far from the source of water.
