adhesive removal

[PACKORACKDAD]

A small company wants me to clean their entry walk and porch area. They had indoor/outdoor over a concrete sidewalk. The "carpet" has been removed, but there is the remaining adhesive on the concrete. Any suggestion on how to remove, or will just hot water and a surface cleaning work?

I would think a good paint stripper would do the trick.

That can be a huge pain! I have seen it come right off and I have seen it impenetrable, and I have never seen it not leave marks after it is removed. I think Nigel is right and an adhesive specific product may be just the trick. I have seen the graffiti remover with multiple solvents remove a lot of things but if you find the right solvent, that will do it. It may be hot water and pressure won't do anything. I would ask around at more than one local chemical supply and please post after the job. One trick for small marks and stuff - carb cleaner , brake cleaner , starting fluid.

3M makes a real good adhesive remover that we have used for truck decal glue, works great for that.

When I moved into my house years ago, the previous owners put astroturf on the front porch, and wifey wanted it gone. I used a wet sandblaster to remove the glue residue effortlessly.

I have used paint stripper, Graffiti remover and a tar remover bofore with good results. Otherwise the wet sandblaster works well but the sand gets messy.

I'm just going to have to get that wet sandblaster.

What about Goof Off?

I have cleaned concrete with adhesive from carpet with 220 degree hot water before

ok, let me tell you what doesn't work, Henrys adhesive removal from Home Depot. I'll post pics later today. A lot of it came off with just hot water. but their were two 4 foot strips that would not come off. So I took Tom's advice and used some Carb cleaner and then WD-40 and a scraper and brush. I first tried to go over it with hot water and work it but found the colder it got the easier it was to remove. Either way, next time I am going to double the price.
