HELP--please -- OLD Brittle Tile and Yellow Floor Glue ????
OK, I want you to try four things on that glue. See if any of the following will soften it:
1. ordinary water
2. mineral spirits, also called "paint thinner,
3. toluene or "lacquer thinner", or
4. nail polish remover, or "acetone".
Any hardware store will sell these solvent in fairly small quantities (like a quart). If none of them dissolve the old adhesive, then the suggestion of borrowing a heat gun (which will ALWAYS work) applies, unless you're willing to spend from $40 to $200 for a new one. Most carpet retailers will let your borrow one of their installers heat guns just to see if it makes removing the glue easier.
Let me know once you get each solvent. Apply a fluid ounce or so of each solvent to the glue and immediately cover with wax paper to prevent it from evaporating. Tape down the edges of the wax paper. Allow time for the solvent to dissove the glue, feel the glue through the wax paper and see if it's softening up. If it is, remove the wax paper and scrape at the glue with a putty knife (or anything). If it's soft, it will scrape off easily.
