Bondo Wood Filler – 30 oz Two-Part Interior & Exterior Wood Repair, Fast-Curing, Paintable & Stainable

Overview

The Bondo Wood Filler by 3M is a high-performance two-part repair compound designed to restore damaged wood with precision and lasting durability. Packaged in a thirty-ounce unit, this filler works for both interior and exterior projects, from furniture and doors to windows and decking. The blend of resins and hardener creates a strong bond that helps repairs blend with the surrounding wood, while offering flexible workability for shaping and finishing.

Expect a practical, efficient workflow. The fast-curing formula is designed to move from repair to finish quickly, enabling sanding and painting in a short window. This can streamline busy projects and reduce downtime on both professional jobs and weekend workshops. The cured material resists common wood repair concerns such as shrinking and cracking, helping your restoration hold its shape through routine use and exposure to the elements.

Finish versatility is another core strength. The filler accepts paint and stain beautifully, so you can achieve a seamless look that matches or enhances the wood grain. In addition to filling, the material can be shaped, sanded, drilled, and routed, providing the flexibility needed to reproduce profiles, fill grain, and refine edges for a clean, professional result.

Whether you are reviving a vintage table, repairing rotted trim, or sealing gaps around doors and decks, this filler is designed to support both quality aesthetics and structural integrity. The product is suited to a range of wood types and project scales, catering to ambitious DIYers as well as seasoned pros who value predictable workability and finish-ready results without overpromising outcomes.
