* FOLLOW DIRECTIONS - make sure to clean the walls or surfaces before you apply these.
* Remove carefully - DENTAL FLOSS will get the stuck pieces off furniture, cabinet doors, and walls without damage. If you're careless and just try to rip them off, you'll certainly wreck something.
Yes, they really DO work, mind how much weight you put on them and you can get very creative. Best hacks around!
I use 3M command strips for almost everything, cafe curtain rods, wall organizers in the bathroom, brooms in my hall closet, posters (poster strips) - not for heavy framed paintings and not for shelves and other things our cats use for perches, but almost everything else. I hate patching holes in textured stucco walls and I love being able to reposition things. WIPE THE WALLS with rubbing alcohol or hand sanitizer first, though, or these things won't hold weight, they'll just grab your dust.
I bought these to hang soundproofing panels and bass traps in a studio room. Because the 3M strips don't stick directly to foam, I made a sandwich of the 3M strips with the heavy-duty 2-sided mounting strips that came with the soundproofing. Those went on the foam, where they stuck so well I wouldn't want to remove them.
Fortunately the 3M hanging strips stick to the mounting strips *AND* to the painted textured stucco walls in my studio, so I could put up my soundproofing, adjust positions, and even remove everything when I move to a different place. The soundproofing is too expensive to throw away so I'm delighted I found a way to make it removable!
I also used 3M rope light hooks to suspend some foam panels from the ceiling to hang down behind my workspace, and 3M hanging hooks to mount soundproofing curtains (using binder rings and binder clamps instead of expensive hanging rings).
Thanks, 3M! Studio's all set!
