Installing wallpaper can transform a room in a way that paint simply cannot, adding texture, color, and personality to your space. Whether you are looking to create a bold feature wall or refresh an entire room, the process requires patience and a methodical approach. This guide walks you through the essential steps to achieve a professional-looking finish without the need for expensive tools or prior experience.
Choosing the Right Wallpaper and Tools
Before you begin, selecting the correct materials is crucial for a successful installation. The type of wallpaper you choose dictates the adhesive and preparation method you will need. Prepasted varieties come with an adhesive layer activated by water, while unpasted options require you to apply glue to the back of the paper.
Essential Tools for the Job
Gathering the right tools ensures efficiency and prevents frustrating interruptions mid-project. You will need a sturdy ladder, a quality wallpaper paste, a smoothing brush, and a precision utility knife. Additionally, a metal straight edge and a seam roller will help you manage alignment and bonding, while a level helps maintain a perfectly straight vertical line.
Preparing the Wall Surface
A smooth and clean surface is the foundation of a flawless wallpaper application. Imperfections in the wall will show through the paper, so it is vital to address them beforehand. Dust, dirt, or old peeling paint will prevent the adhesive from holding correctly, leading to bubbles or detachment over time.
- Wash the walls with a mild detergent to remove grease and dust.
- Fill any holes or cracks with spackle and sand them smooth once dry.
- Remove any old wallpaper or loose paint using a scraper.
- Turn off the power and remove electrical faceplates if working near outlets.
Measuring and Cutting the Paper
Accuracy in measurement prevents waste and ensures the pattern aligns correctly. Start by measuring the height of the wall, adding an extra 2 to 4 inches at the top and bottom to allow for trimming. If the wallpaper has a directional pattern, you will need to purchase extra material to ensure the design matches seamlessly from one strip to the next.
Booking the Wallpaper
If you are using unpasted paper, the technique known as "booking" is essential. This involves folding the paper paste-side to paste-side without creasing it, allowing the adhesive to activate. Once booked, you unroll it to the desired length and cut it, giving the paste time to soak into the fibers before application.
Applying the Adhesive
Whether you are using paste or prepasted wallpaper, the adhesive layer must be consistent and even. For unpasted varieties, roll the adhesive smoothly onto the back of the paper using a paint roller, ensuring complete coverage without overlapping. With prepasted paper, you will roll or spray water onto the back and let it sit in the booking phase.
Hanging the First Strip
The first strip sets the tone for the entire project, so positioning it correctly is vital. Identify the center point of the wall and use your level to draw a vertical guideline. Carefully align the top edge of the wallpaper with this line, gently smoothing the paper down the wall with your brush to push out air bubbles and ensure a tight fit against the surface.
Smoothing and Adjusting
Work from the center outward, using a smoothing brush to glide over the surface. This removes trapped air and ensures the paper adheres smoothly to the wall. If the paper slides or bubbles, carefully lift it and re-adjust; working quickly is necessary before the paste sets permanently.
Trimming and Final TouchesOnce the paper is firmly in place, use a sharp utility knife and the metal straight edge to trim the excess paper at the top and bottom of the wall. Cutting away the overhang ensures a clean, finished edge where the wallpaper meets the ceiling and baseboard.
Finally, use a seam roller to gently press the edges where the strips meet, ensuring a strong bond. Allow the adhesive to cure according to the manufacturer’s instructions before cleaning up any paste residue. With the walls dry and the excess trimmed, you will enjoy a fresh, professionally installed look that elevates the entire room.
