I applied a sticky back paper to my church interior cement block walls so Icould decorate for a children's bible school. After pulling off the paper the adhesive stayed on the wall. Now the wall is picking up dirt. I have tried goo gone did not work. Thanks for any help I can get.

I doubt it will completely come of because of the ruff texture of the block. I'm assuming painted block. Did you try a hair dryer to loosen the glue and a rag tap to get glue to stick to rag and rotate rag. Or just heat up enough to try and peel it up.

Another possibility is use evaporating thinner. That can be found in an Auto store, or the auto paint supply house. It may take the paint with it. It is used on cars to take off tar splatters on lower spots of cars. It evaporates quick so it doesn't hurt the paint. It a possibility here. Always test in a non conspicuous spot first

Goof off, mineral spirts and any other solvent that will not dissolve the wall paint. My guess is that block wall is painted with inexpensive latex interior paint like most institutional buildings. It is not going to clean up like new, sorry. Try the stuff we both recommend but I think the paint surface will start to appear ike you sanded it.

I thought the same thing that's why I posted the Test spot. Any painted block wall is tuff simply because of texture. Most all I know are latex.

I saw you Bal1 answering and was hoping you had a trick, Your are pretty sharp in these areas not to mention a whole lot of "MANY others."

My solution was to repaint after aggressive removal of adhesives on our jobs, Hoping I could get the squeak by thing.

That's why I thought an outside chance an evaporating thinner was the best shot and not attack the finish so much. It will probably dull the finish "sanded look"

It all depends on the sheen and the type of paint. A high gloss paint, even latex, stands a chance of cleaning but flats are almost impossible to fix. You get a shiny spot at best but usually it abrades right through the surface.

Try spraying WD 40 on the adhesive. It's a strong greaseless solvent that usually penetrates all adhesives. Work on a small area at a time... If that doesn't work you could try a wall paper steamer... but at any rate you are going to make a mess.
