1. Surfaces must be clean, dry and free of dirt, grease, oil or water.
2. Squeeze the tube and push filler firmly into the crack / hole and smooth off the surface with a spatula/scraper.
3. Since this filler is virtually non-shrinking, no excessive overfilling is required.
4. Allow 2-3 hours to set in 2mm applications. Allow for longer drying times for thicker applications and cooler weather.
5.Once completely cured, it can be sanded to a feathered edge.
