Hello @anggayuzan, wallcovering instantly changes the look of a space in ways and patterns that paint finishes couldn't. However, there are also advantages to using paint in certain applications. There are many types of wallcovering (paper backed,fabric backs, solid vinyl etc. etc.) and their use depends on the type of projects and areas where they should be applied. Paper type wallcovering is usually used for residential projects only while commercial spaces require certain standards. It also depends on the budget and the overall "look and feel" you'd like to achieve. Thanks for sharing your wallcovering application here with us and welcome to Architecture+Design Community!
