Wallpapering a room is a transformative project that can instantly elevate the atmosphere and character of any space. While it may seem daunting, a methodical approach turns the process into a rewarding experience. Success hinges on thorough preparation, selecting the right materials, and mastering the technique of smoothing. This guide provides a structured pathway to achieve professional-looking results on your first try.
Assess Your Walls and Choose the Wallpaper
Before purchasing a single roll, you must evaluate the condition of your surfaces. Smooth, dry, and slightly porous walls are ideal for wallpaper adhesion. If your walls are glossy, damp, or crumbling, you will need to repair them first with a sealant or plaster. Equally important is choosing the right wallpaper for the environment. Standard paper is suitable for living rooms, while vinyl or grasscloth offers durability for high-traffic areas like hallways or children’s rooms. Consider the pattern repeat; a large-scale design requires more precise cutting and can increase waste if you are new to the process.
Gather Tools and Materials
Having the correct tools is essential for efficiency and precision. You cannot rely on guesswork when timing the paste or aligning patterns. A solid toolkit minimizes stress and prevents delays mid-project.
- Paint roller and tray (for paste application)
- Smoothing brush or plastic smoother
- Utility knife and cutting mat
- Tape measure and level
- Paste (pre-mixed or powder) and mixing bucket
- Seam roller
- Ladder
Measure and Calculate
Accuracy in measurement prevents the frustrating discovery that you are short on material halfway through the job. Measure the height of the room from floor to ceiling and the width of each wall. Remember to add an extra 4 inches to the height for trimming at the top and bottom. Wallpaper is often sold in double rolls; calculate the total square footage of your walls and divide by the yield of a double roll to determine quantity. Always buy one extra roll to ensure a perfect match for future repairs.
Prepare the Surface
Skipping preparation is the most common cause of failure, leading to peeling or bubbling. The wall must be a clean, dry canvas. Wash down the walls with a mild detergent to remove dust and grease, then rinse thoroughly. Fill any holes or cracks with spackle and sand them smooth once dry. If you are wallpapering over existing wallpaper, the old layer must be stripped completely. Lightly sanding the surface creates a grip that allows the adhesive to bond securely.
Cut and Paste
Once the surface is ready, it is time to mix the paste and cut the strips. If using powder paste, mix it to a smooth, oatmeal-like consistency and let it sit for the time specified on the label. Unroll the wallpaper onto a clean surface and cut the first strip to the exact height of your wall, adding the trimming allowance. For patterned wallpaper, lay the strips side by side to check the alignment before applying paste. Apply the paste evenly to the back of the paper using a roller, ensuring full coverage without creating thick globs. Fold the paper paste-side inwards and let it "book" for the recommended time; this allows the adhesive to activate and makes the paper more pliable.
Hanging and Smoothing
The final phase requires patience and a steady hand. Align the first strip with the corner of the room, ensuring it is level with a measuring tool. Carefully place the paper onto the wall, smoothing it down from the center outward to push out air bubbles. Use a smoothing brush to glide over the surface, working out any wrinkles or trapped air. Immediately after hanging, use a seam roller to press the edges together firmly, creating a tight seal without damaging the paper. Proceed to the next strip, matching the pattern precisely to avoid a disjointed look.
Trimming and Cleanup
Once all strips are in place, the job is nearly complete, but attention to detail is critical. Use a sharp utility knife and a metal straight edge to trim the excess paper at the ceiling and baseboard lines. Score the paper lightly before cutting to ensure a clean edge. Wipe away any excess paste with a damp sponge before it dries, as dried residue can stain the wallpaper. Finally, step back and inspect your work; running your fingers along the seams will reveal any lifting edges that require a quick application of paste to secure.
