• Surfaces and materials should be clean and free of dust and grease. When used as adhesive: apply in beads or dots onto the material which needs to be bonded, press the material strongly onto the substrate and leave to set. When used as sealant: apply in a regular bead and smoothen immediately with Soudal Joint Finish or a soapy solution. Optimal application temperature +5°C until +25°C. Final strength will be achieved 24 hours after application.
