Good to know

For best results, ensure surfaces are clean, dry, and free from dust and grease before application. Apply at temperatures between +5°C and +40°C. The sealant skins over in about 10-15 minutes, but full cure takes approximately 1 mm per 24 hours depending on conditions. Once cured, it can be painted with most common paints. Clean tools and excess sealant with water before it cures. Store in a cool, dry place and use within 12-18 months of opening for optimal performance.
