Technical Notes
Substrates must be solid, clean, dry, and free from grease or dust to ensure optimal adhesion. For porous surfaces, priming with a mixture of one part Bostik A325 and two parts water is recommended to improve bonding. The sealant cures by water evaporation, forming a durable, flexible rubber that maintains its elasticity over time.
Application temperature should ideally be between 5°C and 40°C. The product is designed for interior use only and should be protected from moisture until fully cured. Drying time varies depending on joint size and environmental conditions but typically completes within 24 hours.
