Remove Carpet Glue from Concrete
What may I use to remove indoor/outdoor carpet glue from a concrete slab?

we use a walk-behind edco diamond grinder

May you or someone recommend a solvent/cleaner solution like a paint remover-like product, etc.?

I never had any luck with solvents -- just melts the top of the glue and spreads it around.

What are you trying to do? Do you just need a flat surface for another covering or are you trying to stay with bare, flat, even color concrete slab?

If it's outdoors, I would fire up my pressure washer to clean it.

I want to get the concrete slab back to its original state so I may thenapply a slip resistant paint. The slab is indoors.

since concrete is porous, the glue's penetrated the surface & nothing will get it back to the ' original state ' once its changed,,, some like franmar's beanee-doo however its very slippery & the resultant stains are a pita ro remove so we don't use it,,, there is no paint that will satisfactorily adhere to conc im-n-s-h-fo :rolleyes: however there are coatings into which you can mix traction grip

I think I am going to try the Franmar Beanedoo. Thanks to all!

good luck - there's definite reasons we do NOT use it - 1, its more expensive; 2, its very slow; 3, cleanup's a LARGE pita, & 4th, whatever you try to put on top probably won't adhere.

it IS, however, YOUR home !

The Franmar product looks interesting, but it seems to be focused on adhesives that are soluble in oils, like asphalt is. The MSDS shows it to be mostly long chain fatty acids and maybe a little organic solvent. As a test before buying it, you may want to see whether mineral spirits or kerosene softens the adhesive on your floors.

Do you know if the adhesive is water based or oil/solvent based? If it is a water-based latex, removing it could really be tough. How big an area are you dealing with? That is, just a few spots or is it most of the floor?

Some other options:

1) Peel Away makes products for removing adhesives and paints. I have used both its "green" version and its original caustic versions. The green version tends to dissolve and smear; the caustic denatures and removes.

2) Your adhesive may not need to be removed. Maybe it can just be scrapped to the surface and smoothed. Your new coating may stick to it.

3) If you do use the Franmar product, please let us know how it works.

Rubbing alcohol will remove the residue after most of it is scraped off. It will be very hard to get it clean enough to paint. Latex adhesive, which is what is normally used indoors, will not usually soak in much.
