The limited supply of wood from natural forests makes markets interest to wood from plantation forest increase. However, the wood comes from plantation forests considered to be low in quality, including durability. Finishing is one of the solutions to overcome these problems. In this present day there has been developing water based finishing materials (waterbased finishes) that is safe for the environment and does not contain harmful chemicals that can threaten human health. A study has been conducted to determine the durability of the water based finishing layer (Impra Aqua and Sayerlack Waterborne) on Teak (Tectona grandis), Camphor (Dryobalanops aromatica), and Pine (Pinus merkusii). The type of testing conducted covers on the hot and cold test, resistance to household chemical materials, and cross-cut test. The test results showed that the finishing layer is resistant to the hot and cold test, thus can be classified into class 10 (with a completely unblemished surface). The Layer formed by Impra Aqua finishing material is also resistant to all household chemicals tested, so it is classified into class 10. Meanwhile the layer resistance of Sayerlack Waterborne finishing against ballpoint ink tend to be less powerful, so it is classified into class 9, but the finishing materials is resistant to chemicals such as Povidone-iodine. In the test results of paint adhesion (cross cut test), teak wood in wet conditions coated with both types of finishing materials has the weakest adhesion strength, so it is classified into class 3B. Meanwhile, finishing layer for all the wood samples under dry conditions have very strong adhesion, so it is classified in class 5B.
