To obtain a maximum bond, surfaces need to be smooth, non-porous, clean, dry and free of all debris, oils and solvents. Clean the surface with a low strength solvent such as isopropyl alcohol (rubbing alcohol) or heptane. Follow solvent manufacturer’s precautionary warnings and suggested handling procedures when using solvents. Bend pad slightly grasping bumper on sides without touching the adhesive. Apply to surface with enough pressure to ensure a complete bond. Allow a dwell time of 24 hours before exposing to heavy force or weight. The composition of this product contains no migratory plasticizers of any kind, which would mar surfaces of contact. Users should evaluate the suitability of our Bumpers for a specific application under actual conditions.
