Product Information

Full details

Tetrion Woodfil 2K Filler is designed for professional carpenters, furniture restorers, and DIY enthusiasts who require a high-strength, waterproof solution for wood repair. It provides a durable, smooth surface that mimics the properties of natural wood, making it ideal for structural and cosmetic fixes.

FAQs

Can I paint over Tetrion Woodfil immediately?

Wait at least 45 minutes at room temperature for the filler to fully set before applying paint or varnish.

Is this filler suitable for marine environments?

Yes, it is resistant to water and seawater, making it excellent for outdoor and marine-grade repairs.

Can I use this to fill large gaps?

Yes, its structural strength allows it to fill deep cracks, but deep repairs may require layering to ensure a proper set.

Does the filler shrink when it dries?

The product is designed for minimal shrinkage, but it is always recommended to slightly overfill and sand back for a perfectly flush finish.

Can this be used on metal or plastic surfaces?

No, this is specifically engineered for wood-to-wood adhesion and may not bond effectively to non-porous surfaces.

Troubleshooting

Filler is setting too quickly

Reduce the amount of hardener used or mix smaller batches to ensure they are applied within the 5-10 minute window.

Surface is tacky after 45 minutes

Ensure the ambient temperature is not too cold; if the temperature is below 15°C, curing may be delayed.

Filler is pulling away from the wood

Ensure the wood substrate is completely dry and free of oils or wax before application.

  • Works and feels like natural wood when machined
  • Suitable for both outdoor and indoor exposure
  • Resistant to chemicals including oil and petrol

Setup, Compatibility & Care

Before application, ensure the target area is free from dust, grease, and loose debris. Mix the two-part formula thoroughly according to the provided ratios until a uniform color is achieved. Apply the mixture slightly proud of the surface to account for shrinkage during curing, then sand back flush once the filler has hardened. Always store the containers in a cool, dry place and ensure lids are replaced tightly to prevent contamination of the components. For best results, use within the recommended temperature range and avoid applying in direct, intense sunlight which may further accelerate the setting time.
