Professional Wallpaper Installation Techniques

The first step involves studying the design and planning the panels. For repeating patterns—floral, geometric, or panoramic—it's essential to understand where to place the first strip, which wall to treat first, and how to manage subsequent strips, so that the decoration is centered or properly developed in relation to doors, windows, and key furnishings. In many cases, the starting point is chosen on the most visible wall, or to avoid complex transitions in the corners.

The glue should be selected based on the type of paper: some require specific glues for vinyl, others work better with ready-to-use adhesives or methylcellulose-based powders. Glue preparation, resting times, and application methods (wall, paper, or a combination) follow the manufacturer's instructions. Glue that is too thick or too diluted can hinder the sliding of the sheets and compromise adhesion.

The actual installation is carried out one sheet at a time. Each strip is cut to a specified length , positioned flush with a perfectly vertical line drawn with a spirit level or laser, and gradually applied with soft brushes or special spatulas, starting from the top and working downwards. During this phase, air bubbles are eliminated, proper adhesion is checked along the edges, and the design is perfectly aligned with the previous sheet.

The seams must be virtually invisible. The paper is placed precisely, avoiding overlaps or gaps. In complex patterns, such as panoramic ones, millimeters make all the difference: a slight rotation or a small slip can break the continuity of the design. This is why installation requires time and concentration, without forcing or rushing.

Corners, recesses, sockets, and light fixtures are handled with very sharp cutters and frequently replaced blades to maintain clean, crisp cuts. Internal corners require special attention: depending on the paper and substrate, you may decide whether to extend the roll beyond the corner or stop it slightly beforehand, then overlap the next roll almost imperceptibly.

Throughout the installation process, it's important to immediately clean off excess glue , especially on vinyl or embossed paper, using soft sponges and clean water. Dried glue residue can leave shiny streaks or stains that are difficult to remove later.

A professional installation is recognizable by barely visible joints, perfectly aligned sheets, continuous designs even in the corners and around openings, no residual bubbles and an overall tidy appearance, as if the wall was "born" with that decoration.
