3M Double Sided Foam Tape 0.5" x 10Ft, Double Coated Urethane Foam Tape 4026 Adhesion Polyurethane for Bonding Attaching Mounting Interior Signage Nameplates DIY Card, 1 Pack, White

As a teacher, I can say that this stuff is GOLD. It never falls down but is tricky to remove when you don't want something on the wall anymore. The trick is to use a hair dryer. We use this to mount things to project boards—it really makes things “pop”. I only wish I had remembered to get the thicker version, but double stacking it worked perfectly. I highly recommend for students, teachers and those wanting something that holds to painted cinder brick school/dorm walls.

This is the only thing that I have found that will let you put things in the concrete wall at schools.

This tape sticks to surfaces where other products fail.

This tape is really good. Holds almost anything and you can peel it off the back.

Good

Just what I needed to attach an extension cord to my bedside table. It holds it securely with no issues.

I love this stuff! I use it for everything in this case I was putting in a window vent for a portable air conditioner. Using insulation foil I need something that will stick to the thin plastic insert and he foil and hold through the heat and cold!

Looked carefully at all the options for foam tape for securing metal weights in my model trains, and finally decided on this particular product. I had a number of projects on hold waiting for it; and when it arrived I used the tape immediately. It was perfect - it holds the weights in place without using chemicals that can distort or warp the model being weighted.It is also a perfect width and so far it holds the weights firmly. The foam cushion allows for imperfections in the weights and model surface - and I expect long-life plus the ability to add additional weight if needed. Excellent product that has the authentic 3M logo, so I feel the quality is there, also.
