The sealant must be applied on a correctly prepared surface. The technical data sheets will therefore provide the specific instructions for each individual product. Generally:
- The surface must be clean, dry and free of dust and grease.
- Use primer if required (for porous surfaces).
- The ambient and substrate temperature must be more than +5 °C. A frozen surface may lead to very poor adhesion or even no adhesion at all.
- Never use a silicone sealant in the rain.
For information on specific products, please visit the sealant section and review the technical data sheet for the individual product.
