<p>Everything I have hung with 3M has fallen off the wall. The wall is now barren.
What else is there for painted cinderblock walls? A good glue?</p>
<p>When I had to deal with cinderblock the only thing that worked was gorilla tape, which worked fine.</p>
<p>What are you trying to hang? </p>
<p>People don’t believe me, but packaging tape works wonders. Rarely peels of the paint, and has held up everything I’ve put on my wall, and on my friends’ walls, and they have concrete. Otherwise, for posters I use the poster putty (any brand), and for other things I have Scotch removable foam square pads (sticky, obviously). Not sure how well the foam pads would stick to the cinder block, though. So far it’s worked great on wood and my walls (which are not cinder block).</p>
<p>Have you been using the poster hanging things? Or have you tried the velcro-type ones that are meant for framed pictures and stuff? Because I’ve found that a lot of times the poster hanging ones won’t stick properly to my walls (which aren’t cinderblock but are painted with the same obnoxious shiny paint as most cinderblock I’ve seen, which gets damaged crazy easily by tape and repels poster putty), but the velcro-type ones work wonders. The key is to NOT follow the package instructions. Stick one side of the strip (or strips, as it were) to the wall, press it into the wall until your fingers bleed, then leave it for an hour or so. THEN match up the other velcro side and push it into place, peel off the backing, and press your poster against it. I had a poster last year that I tried EVERYTHING to hang (poster putty, poster strips, tape – which took paint off the wall AND fell down immediately), eventually I bought these in a fit of desperation at the campus bookstore, and didn’t have a problem after that.</p>
<p>Obviously if you’ve tried them, I have no suggestions. But I empathize with your frustration.</p>
<p><em>sigh</em></p>
<p>3ms won’t work on cinder <em>tried it</em> but poster putty works on it ;p as does tape</p>
<p>i use my own bodily made adhesive. works everytime. also use it for gel and such. hasnt failed me yet</p>
<p>o.o thats disturbing.</p>
<p>I got packaging tape to work this year but it never worked when I was dealing with cinder block.</p>
<p>hmmmmmmmm duct tape. works for everything ;D</p>
<p>i so far havent had a problem with stuff falling off- but my wall is like paper so yeahh</p>
