What tools do I need to apply KwikWood?

Troubleshooting

Putty is difficult to mix.

Ensure the putty is at room temperature. If it's cold, warm it slightly (do not overheat). Mix thoroughly until the color is uniform.

Putty doesn't adhere properly.

Make sure the wood surface is clean, dry, and free of any loose particles. Roughen the surface with sandpaper for better adhesion.

Putty is still soft after curing.

Ensure you've allowed the putty to cure for the full hour, or longer if in a cool environment. The cure time can be extended in cooler temperatures.

Difficulty in sanding the cured putty.

Use progressively finer grits of sandpaper to achieve a smooth finish. Ensure the putty is fully cured before sanding.
