What surfaces can I use this on?

How should I store the filler?

Can I use water-based paint over this filler?

How deep can I fill in one application?

Do I need to sand the filler?

Troubleshooting
Filler is not adhering to the surface.
Ensure the surface is clean, dry, and free of loose material. Consider lightly sanding the surface for better adhesion.
Filler is cracking after drying.
Ensure the filler is not applied too thickly in a single layer. For gaps deeper than 10mm, apply in layers, allowing each layer to dry completely.
Filler is taking longer than expected to dry.
Check the surrounding environmental conditions; ensure it's not damp or cold. Allow additional drying time if needed.
Difficulty in smoothing the filler.
Use a wet spreader to smooth the filler. Wetting the spreader will prevent the filler from sticking and allow for a smoother finish.
