If you or your client are overly concerned about seams, perhaps paint would be a better decorating solution than wallcovering. If your client doesn't have a problem with the seams on their own, creating one doesn't serve either of you any purpose. Repairs during installation are far easier than those performed after the adhesive has dried. This can be especially true when less than adequate wall preparation has occurred. Echoing wallcovering and adhesive manufacturers, there is no substitute for an acrylic wallcovering primer applied at the proper spread rate over a sound surface.
False economy becomes most obvious when attempting repairs.
When wallcoverings have dried, easy removal is critical. Any damage to the wall surface during removal delays the repair and possibly compromises its appearance. This adhesive is often specified for large commercial projects. According to adhesive sales figures, it is preferred by installers and considered a universal adhesive. Using a strippable adhesive on any other type of wallcovering will not promote strippability.
