  2. The seal needs to be located centrally in either the door leaf or frame.

  3. Route a groove suitable for the size of intumescent seal selected. Clean the rebate to remove any dust. Remove the self-adhesive backing liner from the product and push fit into the routed groove.

  4. To achieve excellent adhesion seals must be applied to clean, dry surfaces at temperatures between +5°C and +40°C.
