woodfilled

Woodfilled is a term used to describe materials and techniques for filling imperfections in wood surfaces. In woodworking and furniture repair, woodfilled materials are applied to gaps, cracks, nail holes, and voids to create a smooth base for finishing. They may be premixed or mixed on site and come in water-based, oil-based, epoxy, or acrylic formulations. The choice of formulation depends on the project, the level of finish, and compatibility with subsequent finishes. Woodfilled products typically contain a binder, a filler which can include wood fibers or pigments, and sometimes a solvent or stabilizer. Some are designed to be stainable, while others are chosen for paint-ready surfaces; epoxy and polyester fillers offer high strength for larger repairs but can be more difficult to color-match.

Applications include repairing furniture, cabinetry, trim, and boat interiors, as well as leveling routed or planed surfaces before finishing. Application methods vary: a putty knife or knife-like tool is used to press the filler into the defect, the surface is smoothed, and after curing the excess is sanded flush. Finishing outcomes depend on how well the filler accepts stain or paint, the filler’s hardness after curing, and the wood species involved. A common limitation is that some fillers do not flex with wood movement, which can lead to cracking or separation over time.
