We we're cleaning a floor this morning prior to stain and run into a new (for us) contaminate on the slab. It appears to be an adhesive type insulation like that "Great Stuff" expanding foam. There are no clumps of the stuff, just spots where it dripped then was scraped off. I can see through speaker and light can openings that the entire celing area was sprayed. TSP didn't touch it nor did lacquer thinner and hand scrubing. I'm going to try Soy Gel tomorrow. What a pain in the ----. Anybody run in to this stuff?

Just as an update, nothing we tried would touch that stuff. I spoke with the contractor who installed the foam and he advised that even the solvent they use to clean the guns will not remove the foam from the pores of the concrete. It is designed to draw into the surface for adhesion. I hated to do it but we walked on that job, no charge to the customer and no hard feelings.

a grinder would touch that stuff. and an overlay would cover it up. did you propose that option?
most of that stuff is urethane-based. a standard paint remover may not remove it, but an industrial coating stripper would, such as removall by napier.

Yep, just as prior post said.. best to grind and overlay. We did a house that had it around the whole perimeter of the slab.. as it was sprayed in all the exterior walls. Nothing seems to take it up fully.. so we ground and overlayed.

We proposed the overlay but the customer decided to go with wood.

what do you guys think about using Kemiko golden wheat stain with some cola effects to help disguise some of the spots. The spots look light tan/gold and I figured I could help disguise them like this.

Try using dye in conjunction with stain, you can use the dye to faux the colors .
