Troubleshooting
Filler is too hard to apply
Ensure the tub has been stored correctly. If hardened, it may be past its usable life.
Filler is shrinking or cracking
This is unlikely with the High-Performance formula. Ensure you are applying to a clean, stable surface and not applying excessively thick layers in one go if the damage is extreme, though it is designed for deep fills.
Filler is not hardening
Ensure the product has been stored correctly and the lid was sealed. Check the expiry date if available.
Poor adhesion to wood
Ensure the wood surface is clean, dry, and free from dust, grease, or old paint.
