FAQs
How long does JB Weld KwikWood take to set?
KwikWood has a set time of 15–25 minutes, during which it hardens sufficiently for further work. Full cure for maximum strength and durability is achieved after approximately 1 hour.
Can I use KwikWood on painted wood?
Yes, provided the painted surface is sound and clean. For best adhesion, lightly sand the painted area before applying the putty.
What is the shelf life of KwikWood putty?
When stored properly in its original sealed packaging in a cool, dry place, KwikWood can have a shelf life of several years.
Can I sand and paint KwikWood?
Absolutely. Once fully cured, KwikWood can be drilled, sanded, carved, stained, and painted to match the surrounding wood.
Is this putty waterproof once cured?
KwikWood provides durable repairs and is resistant to water once fully cured. It is suitable for many indoor and outdoor applications where wood is exposed to moisture.
How much area can one 28g tube cover?
The coverage depends on the depth and size of the repair. A 28g tube is suitable for small to medium-sized repairs like holes, cracks, or gouges. For larger areas, you will need multiple tubes.
What is the difference between KwikWood and other wood fillers?
KwikWood is an epoxy putty, offering superior strength (up to 2450 PSI) and a faster set time compared to many traditional wood fillers. It also cures to a hard, workable state ideal for shaping and finishing.
Troubleshooting
Putty not hardening
Ensure you kneaded the putty thoroughly until a uniform color was achieved, indicating proper mixing of resin and hardener. Also, check storage conditions; extreme cold might affect curing.
Putty too sticky or difficult to work with
Ensure hands are clean and dry. If it's too warm, the putty may become softer. Work in a cooler environment if possible. Wear gloves to prevent sticking to hands.
Repair is not smooth enough
Apply the putty carefully, smoothing it as much as possible during application. Once cured, use sandpaper to achieve a smooth finish. For very fine details, consider using finer grit sandpaper.
Color mismatch after finishing
Always test stain or paint on a scrap piece of putty or an inconspicuous area first. KwikWood can be stained and painted, but achieving a perfect match may require blending or multiple coats.

Setup, Compatibility & Care
Setup:
- Prepare the Area: Ensure the wood surface to be repaired is clean, dry, and free from dust, grease, or loose particles.
- Cut the Putty: Using a clean blade, cut off the desired amount of KwikWood putty. Ensure you cut through both the resin and hardener sections.
- Knead: With gloved hands (recommended to prevent staining), knead the putty until it becomes a uniform color. This indicates the resin and hardener are thoroughly mixed. Work time is limited, typically 3-5 minutes.
- Apply: Firmly press the mixed putty into the damaged area, ensuring good adhesion and filling the void completely. Smooth the surface as much as possible.
- Cure: Allow the putty to cure. It will harden in 15-25 minutes, but full cure for sanding and finishing is typically 1 hour.
Compatibility:
- Compatible with most wood types.
- Once cured, it can be painted, stained, drilled, sanded, and carved.
Care:
- Store unused putty in its original packaging in a cool, dry place.
- Keep tubes sealed tightly to prevent premature curing.
- Clean tools and hands immediately after use.
