Abstract
The use of wood filler is vital in wood finishing. However, the most commercial wood fillers available in the market
are made of chemical solvent-based resins, such as polyurethane and nitrocellulose. These products contain volatile
organic compounds. This study examines performance of alternative and commercial wood fillers. The alternative
wood fillers were made from the mixture of putty powder and organic resins, i.e. shellac, acrylic and polyvinyl acetate.
The wood fillers were tested on tusam, jabon and rubber wood by assessing their physical, mechanical and chemical
performances in comparison with the most commercial wood filler, i.e. nitrocellulose wood filler. Samples of three wood
species were treated by spreading them with various wood filler solutions. Weight and dimensional changes due to
treatment were determined in wet and dry sample conditions. Chemical and scratch resistance of the wood filler films
were also tested to determine their chemical and mechanical performance. Color similarity of the wood filler treated
samples and control were evaluated using the CIELab color system. The effect of treatment were varied according
to wood species. Tusam samples possess greater weight and dimensional gains than those of jabon and rubber wood
samples. All organic wood filler formula could effectively protect wood from water intrution, comparable to that of the
commercial wood filler (WF). The organic wood fillers had higher scratch resistance, less chemical resistance, and better
color appearance than the commercial WF.
