Your wall should be smooth, clean, dry, and in good condition—free from dust, grease, mildew, or any surface damage.
Remove items like vents, outlet covers, or hooks beforehand. Avoid applying wallpaper on surfaces prone to moisture
or mold. Newly painted or constructed walls need a minimum of 30 days to cure fully and should be properly primed and
sealed. If you notice mold, high moisture, or raw concrete, don’t proceed until the wall is treated and prepped correctly.
It’s the installer’s responsibility to check wall readiness.
