Removing wallpaper from a brick wall can be challenging as the porous nature of the brick can make it difficult for the wallpaper adhesive to fully release. One method is to use a wallpaper steamer to loosen the adhesive, then carefully scrape the wallpaper off with a putty knife or scraper. Another option is to use a wallpaper removal solution or a mixture of vinegar and hot water to loosen the adhesive, then use a scrub brush or sponge to remove the wallpaper. It is important to be cautious and not damage the brick surface while removing the wallpaper.
