Step 1: Prepare Your Walls for Wallpaper Installation

Before hanging wallpaper, preparation is key. Clean the walls thoroughly to remove dirt, grease, or dust that can interfere with adhesion. Repair any cracks or holes with spackle, sand rough areas smooth, and seal the surface with a primer and sealer. Properly primed walls not only help wallpaper adhere better but also make removal easier in the future. Taking this step ensures a smooth foundation and a professional-looking result. If you haven't yet, read our guide to wall preparation.
Step 2: How to Hang Wallpaper Straight

Your wallpaper project depends on getting the very first strip straight. Because walls and ceilings are rarely perfectly square, don’t rely on corners. Instead, measure the width of your wallpaper, subtract half an inch, and mark that distance from your starting point, usually a corner or doorway. This ensures the edge of your first strip won’t end up uneven.
Next, draw a vertical guide line using a level or a plumb line, which you can find at any hardware store. To use a plumb line, attach a small weight to one end of a string and rub the cord with chalk. Tack the top of the line to the wall and let the weight hang just above the baseboard. Once the line stops swinging, pull the cord away from the wall and snap it back to leave a perfect chalk line.
This line is your starting point for the first strip of wallpaper. Align the paper carefully to it, smooth it into place, and remove any excess chalk that could show through. Once that first strip is straight, every additional strip will align neatly, giving your room a polished, professional finish.
Step 3: How to Match Wallpaper Patterns Seamlessly

Matching patterns may seem challenging, but with the right method, it’s simple. Start by measuring the height of your wall from ceiling to baseboard, then add four inches — two at the top and two at the bottom — for trimming. Roll out your wallpaper pattern side up and gently reverse-roll to flatten the curl. Decide which part of the design you want to appear at ceiling level, and measure two inches above that point before cutting.
For your next strip, carefully align the pattern with the previous one before cutting to size. This extra step prevents mismatched seams and ensures a seamless flow across your walls. Whether you’re working with florals, geometrics, or bold prints, properly matched patterns make the difference between a room that looks amateur and one that feels expertly designed.
How To Book Wallpaper
Most of the time, the best method for preparing wallpaper is “booking.” Taking the time to book your wallpaper for about five minutes will prevent the paper from expanding on the wall. This gives the wallpaper adhesive time to activate or saturate the paper.
Booking Pre-pasted Wallpaper
Fill water tray halfway with lukewarm water. Loosely roll wallpaper strip, pattern side in. Submerge in water for 15 seconds. Always follow manufacturer's instructions, because exact times may vary. Pull out slowly, unrolling as you go. Allow excess water to roll off.
Book the paper by folding the top and bottom of the strip loosely to the center with the pasted sides together, being careful not to crease the paper. If you prefer to not submerge the wallpaper, you may apply pre-paste activator with a pasting brush or roller to the back of the paper. You will still book the paper to relax creases.

Booking Non-pasted Wallpaper
Unroll paper and apply adhesive with pasting brush or roller to back of paper, starting at the center and working outwards. Be sure edges are well coated. Book the paper by folding the pasted sides against each other to relax creases. Wait about five minutes, and your wallpaper will be ready to hang. Make sure to follow the instructions for your specific wallpaper paste to get the best results.

Hanging Your Wallpaper
Before getting started, cover your furniture and floor with drop cloths and set aside a wastebasket or box to hold the trimmings. Unfold the top portion of the first pasted strip and align it with your vertical chalk mark, overlapping about two inches of paper onto the ceiling. Make certain the main design pattern is positioned on the wall where you want it and that the strip is lined up perfectly with the chalk mark. Using a smoothing tool, work from the center of the strip to the edges and remove any air bubbles. When the top portion is smooth and the positioning is perfect, unroll the bottom half and continue smoothing, allowing the paper to overlap the baseboard. Double check that all air bubbles have been removed and that the strip is securely fastened to the wall.

Trim
Using the trim guide and cutting instrument, trim off the excess paper at the top and bottom of the strip. Move both tools simultaneously for an even cut. Sponge down the entire strip, including the woodwork and ceiling, to remove any excess paste (be sure to rinse sponge in clean water after each use). Move on to the next strip, taking care to match the pattern and butt the edges of the strips. Do not overlap seams!

Ceilings
Always hang the ceiling covering first if you plan to use matching or contrasting wallcoverings. Note: some random-match patterns have side-to-side shading and require reversing alternate strips top to bottom. Be sure to follow the manufacturer's instructions.
Wallpaper Seams
Well-matched seams are extremely important to the quality of your finished room. After several strips have been hung, roll each seam lightly with a seam roller. Be careful not to roll too hard -- paste may squeeze out, leaving a dry seam and possibly damaging the wallpaper surface. Note: Certain prepasted wallcoverings have instructions not to roll seams. Always read your manufacturer's instructions carefully, and your wallpaper experience should go smoothly!

Doors And Windows
When you come to a door or window casing, overlap the woodwork with the pattern. Position and smooth the paper up to the casing. Make a diagonal cut from the overlapped side of the strip to the outside corner of the casing. This will allow the top portion of the strip to be smoothed flat against the wall. Trim off excess as you did at the top and bottom of previous strips. Before trimming around casings, tap the wallcovering firmly into place with the smoothing tool. Sponge off excess paste and proceed with the next strip.

Wall Corners
Next, measure the narrowest width of the retained strip. Snap or draw another vertical line half an inch less than the narrowest width measurement from the inside corner. Hang the retained strip along the vertical line, tapping the excess into the corner. Gently reach underneath and lift up the strip of paper that was cut directly in the corner and tap the new piece into place, overlapping the corner. Apply a small bead of border and seam adhesive to the overlapped area and lay down the piece that fits perfectly into the corner. Smooth the corners and remove any excess adhesive.


Electric Outlets And Switch Plates
Caution! Use extreme care when working with outlets of any kind. We recommend turning off your electricity before working around any electrical outlets.
Remove plates from switches and outlets. Loosen back plates of any wall fixtures. Proceed normally with hanging your paper until you come to an outlet box. Smooth paper to outlet and mark an outline of the electrical box on the wallpaper with a pencil. Pull the strip away from the wall and make an "X" cut from corner to corner inside the box. Smooth the strip down the rest of the way. Trim off the four flaps inside the box and replace the plate.
To make the plate less noticeable, it can be covered with wallpaper before replacing it on the wall. Select a scrap of paper that will match the area cut out for the opening and place it over the plate (overlapping on all sides). Make a diagonal cut to each of the outside corners and into the inside corners of any openings. Wrap the excess around the back of the plate, smooth and replace.
If you come to a wall fixture, make a cut from the side of the strip in as far as the fixture will be when the strip is positioned. Make an "X" cut at the end of the cut. Slip the strip behind the back plate, allowing the fixture to slip through the cut slot and into the "X." Trim the four flaps from the "X" cut, then smooth and rejoin cut edges on the other side and continue smoothing the paper.

Glossary Of Terms For Wallpaper Installation

- Deglossing: The breaking down of a glossy painted surface so that wallcovering will adhere to the surface properly.
- Lining Paper (blank stock): A blank wallcovering used to cover a rough wall to provide a smoother surface.
- Non-Porous: A surface that cannot be penetrated by moisture or air. Examples include solid vinyl wallcoverings or oil-based paint.
- Pattern Match: How the wallcovering matches from strip to strip. There are three types: 1) Straight Across Match where every strip is exactly the same; 2) Drop Match where every other strip is the same; 3) Random Match where there is no noticeable repetition to the design.
- Pattern Repeat: The length of a pattern before it repeats.
- Plumb Line: A tool used to drop a perpendicular line on a wall to aid in hanging a strip of wallcovering vertically.
