Hanging wallpaper successfully is less about having the steadiest hands and more about meticulous preparation and a systematic approach. While the prospect of transforming a room with a bold pattern or textured finish is exciting, the process demands patience and attention to detail. This guide provides the essential tips for hanging wallpaper that ensure a professional-looking result, saving you from the frustration of bubbles, misalignments, and wasted materials.
Preparing the Wall is Paramount
The single most critical step in hanging wallpaper is the preparation of the wall surface. Skipping this step is the fastest route to failure, regardless of the quality of your adhesive. You need a surface that is completely clean, dry, firm, and dust-free. Any existing loose paint, flaking plaster, or grease must be addressed before you unroll a single strip.
Addressing Surface Imperfections
For walls with cracks, holes, or uneven textures, these imperfections will telegraph through the new paper. Fill any holes with a high-quality spackle and sand them smooth once dry. If you are covering a glossy surface, such as painted wood or a previously sealed wall, you must lightly sand the area to create a key for the adhesive to grip. A smooth, slightly abrasive surface ensures the paper adheres evenly without peeling away in the future.
Choosing the Right Wallpaper and Adhesive
Selecting the correct materials for the job is just as important as the prep work. Not all wallpapers are created equal, and the type you choose dictates the difficulty of the installation and the tools you will need. Heavy materials like grasscloth or woven textures require a specific adhesive with a longer open time to allow for repositioning.
Understanding Paste and Prepasted Options
You generally have two routes to consider: pasting the back of the paper or using prepasted paper that activates with water. Traditional pasted wallpaper offers greater flexibility; if you make a mistake, you can often peel it down, rinse the adhesive off, and rehang it. Prepasted paper is often favored by beginners because it eliminates the messy mixing of adhesives, but it has a very short "open time" once activated, requiring faster, more precise work.
| Wallpaper Type | Best For | Difficulty Level |
|---|---|---|
| Vinyl Coated | High traffic areas, durability | Easy |
| Grasscloth/Textured | Aesthetic feature wallsIntermediate to Difficult | |
| Prepasted Paper | DIY projects, quick installs | Intermediate |
Measuring and Cutting for Efficiency
Before you mix a single drop of paste, precise measurement is essential. A common mistake is cutting strips too short. You want the paper to extend comfortably from ceiling to baseboard, allowing for trimming with a utility knife later. Always measure the height of the room first; standard rolls are 20.5 inches wide, but the length can vary significantly.
The Booking Method
Once your strip is cut to length, you will need to "book" it. This involves folding the paper paste-side to paste-side without creasing the middle. Letting the adhesive rest or "book" for the time recommended by the manufacturer allows the chemicals to activate properly, making the paper easier to align and smoother to apply. Rushing this step often results in the paper sticking to itself or stretching.
The Hanging Process: Smooth and Steady
When it is time to hang the strip, the goal is to minimize air pockets and ensure a seamless bond. Start from a plumb line or a corner to ensure the room remains straight. Unfold the top half of the pasted paper, apply the adhesive to the wall, and gently lay the paper onto the surface. Work from the center outward, using a smoothing brush or a plastic smoother to push out any trapped air.
Dealing with Trimming and Cleanup
Once the paper is positioned correctly, use a clean, damp sponge to wipe away any excess adhesive that squeezes out from the edges. After the adhesive has dried—which can take a few hours—carefully trim the excess paper from the top and bottom using a sharp utility knife and a metal straight edge. Remember to maintain a slightly overlapping seam at the cut to prevent the edge from fraying or lifting.
Patterns and Repeating Designs
If you are using a wallpaper with a large repeat pattern, the margin for error increases significantly. Matching patterns across seams is a skill that requires patience. You will need to carefully align the motifs, which often means overlapping the paper significantly until the pattern matches perfectly. Once matched, you can trim the excess.
The Importance of Matching
Take your time with this step. A slight misalignment is noticeable in subtle patterns but becomes glaringly obvious in bold geometric or floral designs. Some professionals suggest hanging the entire strip loosely and using a pencil to lightly trace the pattern of the adjacent strip onto the new one before cutting, ensuring a perfect match once the adhesive is applied.
