Would like to apply a solid stain to concrete, however after removing indoor/outdoor carpet the glue used is stuck to the concrete. Tried letting the etching acid soak in but it had no effect on the glue. Varsol softened it so I could scrap the surface but there's still glue left behind. Any suggestions on how to remove it would be welcome. If it can't be cleaned could I put down a leveling compound and apply the stain to that? My easy project is turning into a huge problem.
Thanks
