I think it will be hard to get them apart with damaging them, but you could give it a shot. You will probably need some sort of glue to re-adhere them together.

I have pulled up planks to do a toilet repar. It can be done and still reuse the planks. The problem is that it is very hard to pull planks apart-since the adhesion is excellent, even after being soaked in water for 5 days. It is very easy to tear a plank instead of the adhesion strips pulling apart. I was not the one who replaced the planks after the repair, so it might have been the technique that was used wasn't too meticulous, but there are now little gaps at the seams where they were replaced.

Try a heat gun at the seams...Then more glue...

Thanks for the suggestions.....I figure it can't hurt to try this out. Any suggestions for the best glue, or will any vinyl adhesive be fine? Again, thanks for your responses.
