Going to ask the collective wisdom, (and I'm sure, wit) of the group. I am redoing the kitchen floor. Underlayment is solid, no squeaks, etc.Removing the stick on tiles with heat, so as not to delaminate the underlayment. Tried to pull a small section of the underlayment that did delaminate when pulling a tile without heat. It was stuck to the sub-floor very well, due to very old felt/tar-paper underneath it. Therefore pulling the underlayment and replacing is a no go. The problem is the tile stickum is leaving very sticky residue on the underlayment. Nice and even. If I was going to replace with the same, no problem. But, I'm putting a floating floor down, and want it not to stick. Need some creative, ridiculous or anything in between, solutions. Metalworking content; wife says I get to buy more mill tooling if I get the floor complete this weekend.
