Double-sided mounting tape is suitable for many clean, dry, smooth surfaces, including painted walls, finished wood, metal, glass, and some plastics. Foam tape can also conform to mildly irregular surfaces, but check that the surface is free of dust, oil, and loose material before applying it.

Use permanent mounting tape when you need a long-term bond for items such as relays, siren drivers, circuit boards, or other devices, especially on surfaces with minor irregularities. Choose a removable option for temporary signage, artwork, or installations where you may need to remove the tape with less risk of residue or surface marks.

Apply mounting tape to a clean, dry surface, using enough material to provide broad contact with the device, then press firmly across the tape. For irregular surfaces, use flexible foam tape that can conform to the surface, and hold the device in place while the adhesive bonds.

When comparing mounting tapes, consider the tape’s backing and adhesive: foam backing can conform to irregular surfaces, acrylic adhesive can support removable mounting with less residue, and rubber adhesive can provide an aggressive, permanent bond. Match the tape to the surface, the weight of the item, the amount of surface conformity needed, and whether you may need to remove the mount later.
