It fills missing sections and can be painted, stained, drilled, carved, nailed, planed, sanded, and routed like natural wood.

J-B Weld KwikWood Wood Repair Epoxy Putty
KwikWood is a hand-mixable two-part epoxy putty designed to repair and rebuild wood for household DIY projects. After kneading, it sets in 15-25 minutes and cures in about an hour, with a light tan color. It offers a high lap shear strength (around 900 PSI) and resists shrinking or rot. The putty is easily molded, can be stained, drilled, sanded, or shaped, and is suitable for creating solid repairs in small to medium wood components. This option emphasizes speed and ease for quick fixes without compromising strength.
PC-Woody Wood Repair Epoxy Paste
PC-Woody is a two-part epoxy paste designed to replace missing or rotted wood. It resists dry rot and UV exposure, and is suitable for indoor and outdoor use with an application range of 35 to 115 degrees F and service temperature from -20 to 200 degrees F. The paste offers high tack to minimize drips and sags during curing, helping maintain profile and fit. It’s a versatile choice for larger repairs where structural integrity is critical and a paintable finish is desired after curing.
PC-Woody Epoxy Paste Kit With Mixing Tool
This PC-Woody kit includes two-part epoxy paste in two cans, designed for two-part repairs and rebuilding of rotted wood. The kit retains resistance to water and environmental exposure, making it suitable for both indoor and outdoor restoration. It features similar temperature and adhesion characteristics to the standard PC-Woody product, with added convenience of a dedicated mixing setup to streamline application for larger projects or precise repair work.
REHOUPTY Epoxy Wood Filler Kit
REHOUPTY offers a high-strength two-part epoxy wood filler designed for repairing cracks, holes, and missing sections with strong adhesion. The formula emphasizes moldability, hardness, and resistance to high and low temperatures, as well as damp environments. Once cured, it can be sanded, drilled, and painted or stained, making it well-suited for both indoor furniture repairs and outdoor structural work. The cure properties and temperature tolerance aim to match typical wood behavior in varying climates.
Boncart Epoxy Wood Putty Filler Kit
Boncart’s epoxy wood filler putty is a two-part, high-strength kit designed to quickly repair and rebuild damaged wood. It is paintable and suitable for indoor and outdoor use, with resistance to a wide temperature range and moisture exposure. The filler emphasizes reliable adhesion, minimal shrinkage, and robust hardness, making it apt for furniture repair, trim restoration, and structural touch-ups where a durable surface finish is needed.
TotalBoat Thickset Epoxy Resin Kit
TotalBoat Thickset is designed for deep pours and castings, including river tables, live-edge slabs, and art projects. It’s a crystal-clear epoxy resin that self-levels to a high-gloss finish, suitable for embedding, filling deep voids, and coating surfaces. It can be poured in layers up to 1/2″ thick, and up to 2″ thick per layer for smaller molds. While not a traditional wood filler, it provides a strong, visually striking option for deep repairs and decorative woodwork that requires depth and clarity.
Buying Guide
Key considerations when selecting an epoxy resin filler for wood include curing time, workability, and final finish. Look for products with clear compatibility for indoor vs. outdoor use, and check for stain or paint compatibility if a finished look is important. For structural repairs, prioritize higher adhesion strength, resistance to moisture, and low shrinkage. If you need fast results on smaller repairs, a putty or KwikWood-style product can save time, while PC-Woody and REHOUPTY provide robust, sandable options for larger or more complex restorations. For decorative or deep-fill needs, a deep-pour resin like TotalBoat Thickset enables larger builds with a clear, glass-like finish. Always follow manufacturer instructions for surface preparation, mixing ratios, and curing conditions to maximize durability and color stability. Consider environmental factors such as VOC content and odor, especially for indoor projects, and verify compatibility with stains, paints, or finishes you plan to apply after curing.
Summary of considerations by project type:
- Structural wood repair: Abatron WoodEpox, PC-Woody, REHOUPTY for strongest adhesion and durability.
- Small to medium quick repairs: J-B Weld KwikWood for fast setting and good strength.
- Decorative or deep-fill needs: TotalBoat Thickset for deep pours and clear finishes.
