A: This product is ideal to hang around the perimeter of the room and cover your walls. The plastic is thin with a static charge so it will cling to the wall surface during the removal of the popcorn ceiling. We believe this product is too thin to be used on the floor surface and would suggest using our contractors plastic for that application or paper as they are much thicker. Thanks for asking!
A: Yes, that is the intention of how this is used.
A: Yes you can as we added painters tape to seal the bottom areas where needed.
A: Yes, but is only 4 feet wide. It will only cover down half of a typical wall.
