I just had "marble like" porcelain tile installed. the plastic film over each tile is too had to get off. The installer gave up and left it on, said he never seen plastic film so hard to come off. So far tried a glass scrapper, hot rag, and just manually picking it off by hand... it comes off but too time consuming. What are some other efficient AND safe methods of removing it? thank you
I just did this and tried some of the solutions above. The only thing that ended up working was rubbing alcohol. Soak the plastic as much as you can with a soaked rag. Then pull slowly. Some areas go faster than others - usually the dryer areas (hence the alcohol). It goes faster if you 1) go slow enough to keep the plastic from tearing, and 2) keep broad tension on the plastic with all fingers or the side of your hand. This also keeps the plastic from peeling. It is tedious but there is no other way that worked for me.
Now I just need to find a way to remove the residue left behind!
