A project that was supposed to be putting in window benches has turned into a complete renovation of a three season room. We've replaced electrical, insulation, drywall and have ripped up the carpet on a concrete slab. We want to put down floor tile. Something we have never done before. Where we are stuck is that we don't know if we have to remove the remaining carpet glue that is on the slab. It is uniform and stuck on. If we do, is a stripper like acetone the way to go or will it affect mortar bonding? Help please!
