Can I apply wallpaper to a surface that has been treated with a waterproofing sealant?

It is not recommended to apply wallpaper to a surface that has been treated with a waterproofing sealant, as the sealant can prevent the wallpaper adhesive from properly bonding with the surface. The sealant can also create a barrier that can prevent the wallpaper from adhering properly and cause it to peel or bubble over time. It is best to remove the sealant and prepare the surface before applying wallpaper for the best results.
