The X-Flex wallpaper is an adhesive with sticky backing that attaches to the inside of brick and cinder walls. According to its designers, covering an entire room takes less than an hour. The wallpaper is so effective that a single layer can keep a wrecking ball from smashing through a brick wall, and a double layer can stop blunt objects (i.e. a flying 2×4) from knocking down drywall.
