I have a floor in the basement that had these awful black, asphalt tiles. Lotsa mold too. So I ripped up all the tiles with a floor scraper, disposed of them and then proceeded to bleach the living hell out of the walls and floor to kill the mold problem.
That's all done now and I'd like to lay down these tiles:
I can do this entire room for about $480. Now they say you can lay this stuff down over anything as long as it's free of dirt. But the cutback adhesive (dark brown, looks like used motor oil) is sticky in spots and very uneven.
So for the last few hours I've been screwing around with an adhesive stripper that is supposed to be lifting this stuff up. It is, but no where near all of it. The stuff is probably original to the house so it's 50+ years old. Some of it is so dry that it might as well be the concrete.
So if anyone has ever removed this stuff before, is it possible that the adhesive is too old and dry that a stripper won't remove it? 'Cause if so, Imma cut my losses, get some masonry silicon carbide sand paper and just give the floor a scuffing to get all the ridges off, mop and drop the floor tiles down.
