Overview
J-B Weld formulated KwikWood as a hand-mixable epoxy putty to repair and rebuild wood. After mixing, it cures to the density of wood and becomes part of the repair, with no solvents and no rot, shrink or cracking.
The reason to buy is a structural repair that can be machined like wood, and works inside or outside. The limitation is the short work life and the small stick, which suits spot repairs rather than large rebuilds.
Who it's for
Furniture repairers and woodworkers rebuilding a chipped edge, a stripped screw area or a damaged corner. Big rebuilds call for a larger quantity, and slow careful work is at odds with a short work life.
Pros and cons
- Rebuilds wood sections
- Machinable once cured
- Interior and exterior use
- Short work life
- Small stick size
- Cure time before finishing
- Mixing by hand required
Performance notes
Kneading the two parts by hand starts the epoxy cure, so the putty must be placed within its work life before it stiffens. Once cured it behaves like wood under tools, and it does not rot, shrink, crack or pull away.
