remove old carpet pad glue from concrete floor?

Anybody know how to remove old carpet padding glue from concrete basement floor? Remodeling the room, want to paint the concrete floor (more inside).
I've got an 80 year-old house with a poured concrete foundation and a concrete basement floor. I'm remodeling a room in one corner where they previously had some shag carpet with a carpet pad underneath. Where the carpet pad seams were, there remains a reddish glue on the concrete floor. It runs right down the middle of the floor. It powders a bit when you use one of those big razor scrapers, but it doesn't all come off - just the top layer. I'd like to acid etch and paint the concrete floor (and just put a big area rug in there). Any ideas on how to remove this infernal glue?

You can also use a product like 3M Adhesive Remover with the scraper, but it just makes a bigger mess (IMNSHO).

After you scrape off the bulk as the first two posters said, you might try a solvent to clean the rest off. I've had good luck with Goof-off for such things. I used a gallon of it to remove carpet glue from a linoleum floor once. Be careful though, it's nasty stuff. Wear an activated carbon mask, open the windows and run an exhaust fan.

I have no idea if this would work or not, but have you tried Goo Gone? It has worked well for me to remove adhesives from metal.

Oh and if you're using large quantities of solvent (either Goo Gone or Goof-off) you might want to turn off the furnace and shut off the water heater if it's gas. Solvents and flame are a bad combination.

Use a heat gun to soften the glue. Or use a blowtorch (creme brulee torch perhaps?) to heat the blade of the scraper periodically before using it. Some people recommend a blow torch applied directly to the old glue but that'd make me nervous (possibly irrationally, but I would research that option more before trying it).

I've used turpentine to remove carpet tile adhesive. I then followed that up with some metholated spirits to remove any trace of oil and adhesive. Keep well ventilated, and don't splash it around. Just a moistening of the adhesive or a cloth with which to rub it, you don't need great pools of it.
