What is 3M 4945 VHB tape used for?

It bonds painted signs to trucks and trailers and joins metal, painted and plastic surfaces that need a permanent, weatherproof hold. It also cushions and damps vibration.

How thick is the tape?

The acrylic foam is 45 mils thick, which lets it conform to slightly uneven surfaces and spread stress across the joint.

Does it hold up outdoors?

Yes. The acrylic adhesive resists moisture, UV, plasticizers and solvents, and the tape is rated from -40°F to 200°F.

How do I apply it for a lasting bond?

Clean and dry both surfaces, press the tape down firmly, and apply steady pressure after joining. A clean, flat surface is what makes the bond hold.

No. It is designed as a permanent bond, so removal usually takes mechanical effort and can damage the surface.

One roll of white acrylic foam tape, 2 inches wide by 5 yards long, on a 1.5-inch core with a kraft paper liner. No dispenser is included.
