Wood filler helps you repair, smooth, and refinish interior and exterior wood surfaces with professional results. Whether you’re fixing nail holes in trim, patching dents in furniture, or rebuilding damaged sills, the right filler creates a paintable or stainable base that blends with the surrounding grain and stands up to use.

Choose from water-based wood filler for low odor, quick drying, and easy soap-and-water cleanup; solvent-based options for harder, more moisture-resistant patches; and two‑part epoxy wood filler for structural repairs on rotted or weathered wood. Look for features such as stainable formulas, tintable colors, low shrink, and outdoor rating. For floors and cabinetry, fine-grain fillers and grain fillers level open pores in oak, ash, and mahogany for glass-smooth finishes.

Application is straightforward. Clean the area, remove loose fibers, and undercut edges slightly. Press filler firmly with a flexible putty knife, overfill by a small margin, and let it cure fully. Sand flush through grits, then prime and paint or apply stain and clear coat. For deep voids, build in thin layers or switch to epoxy. Pre-tint with dye or mix with sanding dust for closer color matches. After cure, many fillers accept screws and nails and can be carved or routed for crisp profiles.

Helpful tips: match interior vs exterior formulas to your project; check dry and recoat times; test stain compatibility on a scrap; seal exterior patches with primer and paint; and avoid applying below recommended temperatures. Common formats include tubs, tubes, sticks, and premixed putties for quick hole-filling. Pair with a putty knife, sanding block or orbital sander, tack cloth, and primer for a fast, durable repair.

From baseboards and doors to decks and railings, quality wood filler saves time, reduces callbacks, and improves finish quality on every wood repair. Choose the right product for lasting, seamless results.
