FAQs
What surfaces can Bonda Fine Surface Filler be used on?
It is suitable for use on metal, GRP, plywood, and other fillers.
Does this filler require priming before painting?
The dense finish it provides generally requires no priming prior to topcoat application, though this can depend on the specific topcoat system used.
Is this filler suitable for repairing deep scratches or holes?
No, this filler is primarily intended for surfacing work and smoothing out final imperfections. For deeper repairs, a different type of filler may be more appropriate.
How do I mix the filler and hardener?
Mix the white filler with the red hardener according to the manufacturer's instructions. The key is to achieve a uniform color throughout the mixture to ensure proper curing.
What is the working time or pot life of the mixed filler?
The working time varies depending on temperature and humidity. It's best to mix only the amount of filler that can be applied within the recommended working time before it begins to harden.
How long does it take for the filler to cure?
Curing times are dependent on application thickness, temperature, and humidity. Refer to the product packaging for specific curing guidelines before sanding or painting.
Can I use this filler outdoors?
Yes, once properly cured, the filler is suitable for exterior applications. Ensure it is protected by a suitable topcoat system for long-term durability.
Troubleshooting
Filler not hardening or curing slowly
Ensure the correct ratio of hardener to filler was used. Verify the ambient temperature is within the recommended range for application and curing. Insufficient mixing can also lead to slow curing.
Poor adhesion to the surface
Confirm the surface was properly prepared, clean, dry, and free from any grease, dust, or contaminants before application. Ensure compatibility with the substrate.
Uneven finish after application
This can be due to inconsistent mixing or application. For minor unevenness, light sanding should resolve the issue. For future applications, focus on a more consistent mixing and spreading technique.
Filler is too difficult to spread
Ensure the filler and hardener are thoroughly mixed. If the mixture has started to cure, it will become difficult to spread; only mix what can be used within the working pot life.
