Re: adhesive problem
Mineral Spirits and a flex Stainless Steel sc****r blade will make short work of that old NafCo tile clear vinyl sheet & tile adhesive. The adhesive will get gummy then sc**** one way in the direction of the grain (carefully) then clean sc****r on the edge of a bucket. Work on small areas little less than 2 sq. ft. at a time. Don't try to get it all off in the first pass you'll make yourself crazy. Go for the majority of the bulk then move on, get the rest on a second pass. You may need to let it set for a few minutes. After the second pass use a stripper pad soaked in Mineral Spirits and wipe in the direction of the grain.
You need a lot of fresh air - open the windows - and extinquish all sources of spark and flame before you begin.
