1. Our Reckhorn AD noise insulation is odourless after full-surface adhesion. 2. The edge does not stick because aluminium and silicone paper overlap. 3. The 2 m² is sufficient for 2 car doors and usually for smaller rattling areas. For optimal adhesion, we recommend preparing the surface to be glued: 1. Dust oil and grease free. 2. Lightly sand water repellent surfaces (lotus effect). 3. Improve initial adhesion by warming to 20-40°. Alubutyl and ISO composite mats should be stored at 15-30 °C for 1 day. 4. Press aluminium butyl with wallpaper roller.
