How to remove glued down carpet pad?
I've worked in the floor covering business for several years and here is a good quick way to remove glued carpet padding: after slicing the padding in half length-wise with a utility knife pull up as much as possible. Padding usually is made into 5 foot rolls. Halving it makes it slightly easier to pull up. The installer will normally apply the glue from a gallon can directly to the concrete floor in a continuos serpentine manner so that when the pad is rolled onto the glue it makes contact to just shy of its outer-most edges. I've found a 4"-6" floor scraper helps alot ,too. Also to remove any of the stubborn residual pieces 'kick/ scrape' them with your shoe bottom. It quickly pulls up any remaining pieces. This shoe kicking action also works for padding that is stapled to wooden floors.
