OOOPS!!!! I reposted because it said 109 inch by mistake.I just removed all the "Crud" from under a glued down basement carpet. I got on my hands and knees with a 10 inch metal drywall blade and scaped away while listening to tunes..I did the whole basement in about an hour and it wasn't that hard. Way easier then the way my Hubby had suggested...with a shovel. Just make sure you use a sturdy drywall blade so it doesn't break! Happy scraping.
