Tetrion Powerfil 2K 2 Part Body Filler - Lightweight - Tough - Smooth - White - 600g

The recommended mixing ratio is 1 part hardener to 50 parts filler, which is approximately 2% hardener.

The filler sets in approximately 5 minutes and becomes fully cured and sandable after about 20 minutes at 18 degrees C.

Yes, it is suitable for use on most surfaces including paint, provided the paint is sound and the surface is properly prepared (clean, dry, free of grease).

It is suitable for use on metal, wood, stone, and most plastics.

It is not recommended to alter the hardener ratio as this can compromise the strength and finish of the repair. Stick to the 2% ratio for optimal results.

If you mix more than you can use, apply it to a non-critical area or have a small repair ready. Once mixed, it will start to set quickly and cannot be returned to the tin or reused.

Tools and spreaders should be cleaned immediately after use with water before the filler has cured.

Ensure the correct mixing ratio of hardener to filler (2%) is used. Check that the ambient temperature is within the recommended range (ideally around 18 degrees C or warmer). Insufficient hardener or very low temperatures can significantly slow curing.

This could be due to using too much hardener. Re-measure carefully to ensure the 2% ratio is maintained. Work in smaller batches if necessary, especially in warmer conditions.

The surface may not have been adequately prepared. Ensure it is completely free of dirt, grease, moisture, and loose particles before application. Lightly abrading the surface can also improve adhesion.

This usually indicates an incorrect mix ratio or insufficient mixing. Ensure thorough mixing until no streaks are visible, and verify the hardener quantity. Very low temperatures can also prolong curing.
