*For further guidance on fire performance and testing refer to dooset provider/manufacturer.  The fire rating is dependant on door configuration and performance.

1. Clean the substrate to remove surface oils, failure to remove surface greases may result in a delamination or poor adhesion to the substrate.
2. Remove the self-adhesive backing liner from the intumescent and apply the product to the substrate.
3. To achieve excellent adhesion seals must be applied to clean, dry surfaces at temperatures between +5°C and +40°C.
