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.
