A: Since the adhesive is still sticky, I am assuming they did not use a mastic. Was this some sort of cheap peel and stick laminated floor? You ask such a hard question, I feel obliged to ask one of you in return. Why would anyone glue down such a floor over a solid oak floor that sounds like it is in good enough shape to be refinished? If I had to suggest something to lay on top of this mess so you can at least walk on it, and should not be a serious problem when sanding, I would suggest grey building paper, sold in rolls, probably 3 feet wide by 50 or 100 ft. long.
