I have self stick tiles that are laid directly on a concrete floor. Any suggestions to make the job of removing them easier?? I'm slowly getting the job done with basically a hammer & chisel but there has got to be an easier/faster way. I'll say one thing...they use darn good adhesive. Thanks for any advice.

I did another blooper as a "do it-yourselfer." I layed my own vinyl flooring. Thought I was doing a wonderful job at this project. I had the pattern from the old one that I cut from. Brought it in, layed it down, did as much trimming as possible. Started gluing it down and could only get the edges (probably about a foot inward) glued without trying to tear it. Might I tell you this was about midnight one night. The next morning when I got up, I see I have a warp place right down the middle of my flooring. I thought possibly this would work out-2 months later it hasn't. This expensive flooring is glued to a concrete floor. Any suggestions? I don't want to tear it up, but I'm not happy with the loose hump in the middle of it either.
