Traditional inorganic putty made with calcium carbonate presents some shortcomings, such as poor water resistance and adhesion. The authors of this paper used latex (16% solids content) and wood flour (500 mesh) to make a wood flour putty to improve the water and adhesion performance. Two different latexes (epoxy resin and isocyanate resin) were used in this study and their effects on the performance of wood-flour putty were evaluated. Performance measurements included paint adhesion, water resistance, wear-resistance, and surface drying time. The results showed that both latexes could improve the performance of wood-flour putty. When the addition of the agents was increased, water resistance and wear resistance were considerably improved. Considering all the performance indexes, the wood-flour putty modified with either 8.0% epoxy resin or 2.0% isocyanate exhibited the best performance.
