Preparation
• Prepare the substrate for receiving intumescent hardware protection by ensuring it is clean from dust and oils. We recommend the use of non-solvent-based wipes. Wipe with a non-lint cloth to ensure the surface is completely dry before application.
• Remove self-adhesive backing and dispose of in line with local regulations. Apply intumescent hardware protection, ensuring any cut-outs and relief sections are in alignment with hardware detail. Press firmly.
