Wallpaper—also known as wall covering—is a specialized paper used to cover and decorate walls. It is also an effective way to conceal wall imperfections. Unlike standard paper, wallpaper differs significantly in both composition and appearance; it is crafted from a variety of materials, including coarse fabrics, synthetic fibers, plastics, and thin wood veneers. It is applied by coating the side facing the wall with an adhesive and then pressing it firmly against the surface.
While the application process is not overly difficult, it requires precision to avoid damaging the wallpaper or the wall itself. In this article, we will explain how to apply wallpaper.
How to Apply Wallpaper: Preparing Tools and Equipment. Installing wallpaper requires the following items:
Wallpaper; wallpaper adhesive; a large, flat work surface; a measuring tape; a ladder; and a drop cloth to protect the floor. Tools for wall preparation include: sandpaper, wall filler (putty), and a putty knife; a bucket, water, sponges, and cloths; a smoothing brush; a sharp utility knife or razor blade; and a seam roller. Preparing the Wall: Before applying wallpaper, the wall must be prepared as follows:
Begin by repairing any cracks, nail holes, or areas where the paint or plaster has come loose. Ensure the walls are thoroughly cleaned, completely dry, and that the existing paint is in good condition. To prevent the wall from absorbing the wallpaper adhesive—which would otherwise hinder proper adhesion—ensure the walls are washed and all electrical faceplates are removed.
Examine the walls to determine the starting point; it is advisable to begin in a corner or behind a door. Make a light mark on the wall, positioned 2.5–5 cm less than the width of the wallpaper being used. Using a pencil and a carpenter’s level, draw a faint vertical line from the floor to the ceiling; this line will serve as your starting guide, even if you are beginning in a corner. Choosing a starting point and cutting the wallpaper:
Begin by selecting a starting point—ideally a corner near the curtains or behind a door. Measure from this point and use a spirit level to draw a straight vertical line on the wall; this line marks where the first strip of wallpaper should be placed. Next, lay the first roll of wallpaper face-down on a large, flat table. Take your measurements and cut the first strip to the appropriate length, leaving a few extra centimeters at both the top and bottom. Continue cutting subsequent strips in order, ensuring that the patterns align correctly.
Applying the adhesive: Wallpaper adhesive is typically provided with the wallpaper; prepare the paste according to the manufacturer’s instructions found on the packaging. Once you have ensured the walls are clean and dry, use a paint roller to apply a thin, even layer of adhesive directly onto the wall. Alternatively, you can apply the adhesive section by section—only where each strip will be placed—to prevent the paste from drying out prematurely.
Hanging the wallpaper: Take the first strip of wallpaper and begin at the top-left corner of the wall. Align the strip so that it is perfectly straight, allowing about 30 centimeters of the paper to extend beyond the top edge, and press it firmly against the wall. Smooth the paper down slowly using a brush, ensuring that no air bubbles or creases form during the application process.
Trimming excess paper: A blade or utility knife can be used to trim away excess wallpaper along the ceiling, edges, and near the floor. Afterward, wipe the surface with a clean sponge to remove any remaining adhesive residue.
Suitable rooms for wallpaper: Wallpaper can be applied in any room of a home. It can be used on all walls of a room or just on a single feature wall. It is worth noting, however, that wallpaper is not recommended for damp areas, such as bathrooms.
Advantages of using wallpaper:
Key benefits include the following: Wallpaper can be applied and subsequently removed without damaging the wall. It does not require expensive, specialized tools or materials, making it an ideal solution for tenants who wish to change the color of their walls without causing any damage. It is easy to install and saves both time and effort.
Types of wallpaper: Wallpaper comes in various types, most notably:
Vinyl: Easy to install and remove. Textured/Embossed: Suitable for concealing imperfections on a wall. Fabric/Textile: Difficult to install and challenging to clean.
