Wood Flour

Wood Flour, a fine sawdust that has been filtered so that there are no lumps, is excellent for creating glues and structural fillers and fillets. It is a fibrous filler that is also thixotropic. To make a smoother fillet, some users add a small amount of Silica Thickener. Generally used in wood projects because of its color. It cures to a hard, sandable, paintable solid.
