Experienced installers will always use a "double cut" technique for installing commercial wallcoverings. The printer should provide additional "bleed" into the side of each panel so that the installer can overlap 1 panel onto the next and match the graphics on the wall. Typically the overlapped area will be between 1" and 2".
The installer uses a very sharp blade to cut through both pieces of the overlapped wallcovering. After cutting a straight line down the wall, the installer peels back the top layer and removes the trimmed portion, which results in a clean match on the wall. When done correctly, Dreamscape seams on the wall should be nearly invisible from a normal viewing distance. While many experienced installers will not need any special tools, we highly recommend protecting the drywall surface underneath your wallcovering by using a seam cutting tool. Here are two similar products we recommend that will help you understand how this tool can be used. They allow you to set a metal plate behind the layers of wallcovering that are being cut, essentially shielding the wall from contact with the knife. YELLOTOOLS BODYGUARD KNIFE or ADVANCE SEAM BUSTER
