520			_aA body filler is a type of constructional sealant which is used to fill fissures on cement and wood surfaces. In this study, the researchers developed a type of body filler from oyster shells combined with talcum powder, dolomite, and paint as binder. Specifically, the study was conducted to produce body filler from oyster shells; describe the physical characteristics of the pulverized oyster shells in terms on density, color, and moisture content; and determine the physical attributes of the body filler made from the oyster shells when mixed with liquid binder in terms of adhesive property, water resistance, texture, color, and curing time. The effects of different formulations of the mixture on the physical properties of the body filler were investigated. Laboratory analysis showed that color of the body filler was classified as GLEY 1 8/N = white. The bulk density was computed to be 0.9167 g/cm³, and the curing time of the body filler is approximately 6-8 hours. The physical assessment of the products showed that the treatment 2 (40% oyster shells) has best adhesive property, treatment 1 (50% oyster shells) has the best texture, and treatment 2 and 3 (30% oyster shells) was best in terms of water resistance. These results showed that the oyster shells can be used as an alternative ingredient in producing body filler.
