FAQs

How much filler do I need?

The amount needed depends on the size and depth of the damage. A 250ml tin is generally sufficient for minor repairs.

What kind of sandpaper should I use?

Start with a coarser grit (e.g., 80 grit) for shaping, and move to finer grits (e.g., 180, 240, 320) for smoothing.

Can I use this on plastic?

Not directly. You will need to use an adhesion promoter specifically designed for plastic before applying the filler.

How long does it take to dry?

Drying time is typically 20-30 minutes at room temperature, but this can vary depending on conditions. Check the instructions for precise guidelines.

Do I need to prime after sanding?

Yes, priming is recommended after sanding to create a good base for the topcoat (paint).

How do I store the remaining filler?

Seal the tin tightly and store it in a cool, dry place. The filler may harden over time, especially if exposed to air.

Can I use this filler on my car's roof?

Yes, provided the roof material is metal, fiberglass, or wood and you follow the preparation instructions.

Troubleshooting

Filler is not hardening.

Ensure the correct ratio of hardener is mixed with the filler. Check the expiration date of both the filler and hardener.

Filler is difficult to sand.

Allow the filler to fully cure before sanding. Use appropriate grit sandpaper.

Filler is shrinking after application.

Apply the filler in thin layers and allow each layer to dry completely before sanding. Avoid applying too much filler in one go.

Filler not adhering to surface.

Ensure the surface is clean, degreased, and properly sanded before applying the filler. Use a suitable primer for optimal adhesion.
