Troubleshooting

Putty won't harden.

Ensure that the putty was mixed thoroughly until a uniform color was achieved. Also, check the expiration date on the package. The ratio of the parts is critical for it to cure properly.

Poor adhesion to the surface.

Make sure the surface is clean and free of any contaminants like oil, grease, or loose particles. Lightly roughening the surface with sandpaper can also improve adhesion.

Repair fails after curing.

Ensure the product has fully cured (4-6 hours) before subjecting it to stress or use. If the repair is in a high-stress area, consider applying additional layers or using a reinforcing material.
