I had someone do some floor repairs and they had to temporarily pull up a section of 30 year old vinyl flooring.....when they put that section of sheet vinyl flooring back down they used double backed tape....after the vinyl was put back, a day later, I noticed a spot in the vinyl that was raised, about a 1/4" high and about 2x3" length and width.....probably some debris or something got stuck under the vinyl.....the question is, how hard is it to undue the double sided tape and level out, or fix the bump? Is two sided tape relatively easy to lift apart?
