Product Information
Full details
This Bonda Wood Fill is designed for woodworkers, DIY enthusiasts, and tradespeople needing to quickly and effectively repair timber defects. Its key benefit is rapid hardening, allowing for fast project completion. A minor caveat is its specific brown, pine-like colour, which may require overpainting for perfect aesthetic matching on lighter woods. This superior two-component filler is ideal for filling knots, pinholes, and other imperfections in wood, providing an excellent surface that sands easily for finishing.

FAQs
How long does Bonda Wood Fill take to harden?
The hardening time is rapid, typically allowing for sanding and finishing within a short period. Exact times can vary based on ambient temperature and humidity, but it's designed for quick project turnaround.
Can I paint or stain over Bonda Wood Fill?
Yes, once fully cured, Bonda Wood Fill provides an excellent base for most paints, varnishes, and stains. Ensure the filler is completely hardened before applying any finish.
What is the best way to mix the two components?
Dispense the correct ratio of each component onto a clean, non-porous surface. Mix thoroughly with a clean spatula or mixing tool until a consistent colour and texture are achieved. Work relatively quickly as the mixture starts to harden upon mixing.
How deep a hole can I fill with this product?
Bonda Wood Fill is suitable for filling knots, pinholes, and defects. For very deep holes, it may be necessary to apply the filler in layers, allowing each layer to partially cure before adding the next, to prevent shrinkage and ensure proper hardening.
What is the colour of the filler?
The product is described as 'Brown' and intended for pine, suggesting a colour that complements pine wood. However, for a perfect match on other wood types or for a seamless finish, it is recommended to paint or stain over the cured filler.
Does this filler require a separate hardener?
Yes, Bonda Wood Fill is a two-component system, meaning it requires mixing a base product with a separate hardener to initiate the rapid hardening process.
Troubleshooting
Filler is too hard to mix or apply
Ensure you are using fresh product and that the two components are mixed in the correct ratio. If the mixture hardens too quickly, you may be mixing too much at once or working in a very warm environment; try working with smaller batches.
Filler remains soft or crumbly after application
This indicates an improper mix ratio, insufficient mixing, or exposure to moisture during curing. Ensure the components are mixed thoroughly and uniformly according to the manufacturer's instructions and that the application environment is dry.
Filler shrinks significantly after drying
This can happen if the void is too deep for a single application. For deeper holes, apply in thin layers, allowing each layer to partially cure before applying the next.
Poor adhesion to the wood surface
The wood surface may not have been adequately prepared. Ensure the wood is clean, dry, and free from dust, grease, or loose fibres. Lightly sanding the area before application can also improve adhesion.
Pros and Cons
Pros
- Fast curing time speeds up repair jobs.
- Achieves a smooth, sandable surface.
- Good for filling both small defects and larger imperfections.
- Easy to prepare and use for most DIYers.
- Creates a durable, long-lasting repair.
Cons
- Colour may not match all wood types without overpainting.
- Requires precise mixing of two components for optimal performance.
- Not suitable for structural repairs, only cosmetic filling.
- Can be difficult to remove once fully hardened if misapplied.
Setup, Compatibility & Care
Setup:
- Ensure the wood surface is clean, dry, and free from dust, grease, and loose particles.
- Dispense the required amounts of the two components onto a clean mixing surface. Refer to the product packaging for the recommended mixing ratio (typically a base and a hardener).
- Mix thoroughly until a uniform colour and consistency are achieved. Avoid mixing too large a quantity at once, as it will begin to harden quickly.
Application:
- Apply the mixed filler to the defect using a spatula or filling knife.
- Press firmly to ensure good adhesion and fill the void completely, slightly overfilling to allow for sanding.
- Remove excess filler before it hardens.
Compatibility:
Bonda Wood Fill is designed for use on most types of wood. It is compatible with most standard paints, varnishes, and stains once fully cured. It is not recommended for use on plastics or metals.
Care:
Store unused components in their original, tightly sealed containers in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the mixing surface and tools are cleaned immediately after use with appropriate solvents (check product packaging) before the filler hardens.
