| Summary: | Finishing is to give a desired or particular surface texture meanwhile wood
finishing is a process of embellishing and protecting the surface of a wooden
material. Wood is a porous material. It contains countless holes of various sizes.
These holes can accumulate dirt and grime from handling, atmospheric
contaminants and food. A finish seals the porous surface, making it less
susceptible to soiling. The objective for this study is to choose between two
different finishing systems which are systems A (1 sealer, 2 topcoat) and system
B (2 sealer, 3 topcoat). In addition, the objective is to choose the best viscosity of
the finishes that are suitable for Chengal wood. Acid catalyst lacquer were
applied using spray application and there are three testing to measure the
performance of the finishing which are household test, cross-cut test and heat
resistance test. The data and results show that system B is better compared to
system A as it more layered and the best viscosity is 18 seconds as it easier to
penetrate into the wood grain. |
