How can i remove masking tape from an acid stained concrete floor? tried goo gone.?

masking tape was used to hold down paper to protect the floor while construction was finished. the residue is literally baked on. goo gone and charcoal lighter fluid did not even soften it.


i am a concrete contractor who is clueless what to try next without damaging the floor.


my material supplier had no more suggestions either.How can i remove masking tape from an acid stained concrete floor? tried goo gone.?
Hi-





I had acid-stained concrete floors in my last home - they were awesome! But, my 3- or 4-yr. old son thought that he would repair the surface cracks in the foundation with blue masking tape. We thought it was cute, until we pulled the tape up and had marks on the floor in the shape of the tape.





I, too, thought that this was adhesive residue. It even felt like some residue left over. And I tried goo-gone and some other adhesive removal solutions. Then I got down on the floor for a really, really close look, and realized that what had happened was that the tape actually pulled up little, tiny divits of concrete. So, I was seeing plain concrete show up through the stain, just in little dots, like a pointillism!





What I finally did that worked at least short-term was to use a wood-stain pen - the kind you use to spot-treat scratches in wood furniture - and colored over the spots. The concrete accepted the color,at least for a little while, and the color stain I used was a good match. It was not perfect, but it was far less noticeable than those marks.





If you are a contractor, and have access to the stain color used, maybe try spot-treating it with the stain again. The cement should react to the acid just like it did during the original stain job.

Contact the masking tape manufacturer.


Might also try lacquer thinner...
I've used Prep Sol.


It worked for me when removing old colored tape on my RV.





Maybe Acetone,





Make sure it dosen't discolor stained concrete floor.
You could try a benz0matic torch to burn the glue and then use a stiff brush. Just don't use so much heat in one spot to pop the cement. You can also try pavement sealer remover


( a blacktop product) I have removed blacktop sealer from new concrete with a sealer remover and a wire wheel on the end of a small hand grinder. It worked great.
Don't ya hate it when these things happen? You might try laying down water saturated cloths and rehydrating the tape so it will break down and loosen the dried adhesives. Cover the cloths with plastic sheeting or something to prevent evaporation. It is cheap, harmless and with patience might well work.
