The Beginner’s Guide to Working with Wallpaper – Bob Vila

Wallpaper 101: What Are You Actually Putting on the Wall?

Before you buy a single roll, it helps to know what kind of wallpaper you’re dealing with. Different types have different
ruleslike board games, except the penalty for ignoring the rules is a bubble the size of Florida.

Common wallpaper types (and why you should care)

• Unpasted wallpaper: You apply adhesive (paste) before hanging. Great for durability, but you’re in charge
  of getting the paste rightcoverage, consistency, and cleanliness.
• Prepasted wallpaper: The paste is already on the back; you activate it with water. Beginner-friendly,
  but timing matters (too wet = sliding; too dry = sad seams).
• Paste-the-wall wallpaper: You put paste on the wall instead of the paper. Often easier and cleaner for DIYers,
  and less likely to stretch.
• Peel-and-stick (removable) wallpaper: No paste. You peel the backing and smooth as you go. It’s popular
  for renters and commitment-phobes, but wall texture and cleanliness matter a lot.
• Vinyl-coated or vinyl wallpaper: Tough, wipeable, and often better for kitchens/baths. It can also be less breathable,
  so proper prep is key to avoid adhesion issues.

Quick decision tip: If you’re wallpapering one accent wall and want a lower-mess learning curve, peel-and-stick can be great.
If you’re doing a whole room or a high-traffic space, traditional wallpaper with the right adhesive can be more durable.

Tools & Materials: Your “Don’t Make Me Go Back to the Store” Checklist

Wallpapering is 30% sticking paper to walls and 70% preventing the paper from doing something weird. These tools keep the
weirdness contained.

Essentials

• Measuring tape
• Level or laser level (for a plumb line)
• Pencil (light marks only)
• Sharp utility knife + lots of fresh blades
• Straightedge or wide putty knife (for guiding cuts)
• Smoothing tool (plastic smoother) and/or wallpaper brush
• Seam roller (use gentlyno seam bullying)
• Step ladder
• Clean sponge and bucket of water for paste cleanup

Depending on your wallpaper type

• Traditional: recommended wallpaper paste/adhesive, pasting brush/roller, drop cloth, and a pasting table (or protected flat surface)
• Prepasted: water tray or spray bottle (as manufacturer directs)
• Peel-and-stick: extra smoothing tool, microfiber cloth, and a little patience (okay, a lot)

Measure, Plan, and Order: The Part That Saves Your Weekend

Wallpaper math sounds intimidating until you realize it’s basically “wall area minus holes, plus extra for mistakes.”
The most common beginner error is ordering exactly the amount you think you needthen discovering patterns don’t magically
align by wishful thinking.

Step 1: Calculate how much wallpaper you need

1. Measure each wall’s width and height (in feet).
2. Compute wall area: width × height. Add all walls you plan to cover.
3. Subtract a little for doors and windows (a common rule of thumb is about 10 square feet per door or full-size window).
4. Add extra for waste: typically 10%–20%, especially for bold patterns with a large repeat.
   If your wallpaper has a pattern repeat, you may need even more because you’ll trim off mismatched sections.

Step 2: Plan your layout (especially for patterns)

Wallpaper is a visual story, and patterns love to reveal your shortcuts. Decide where you want the “hero” pattern to land:
behind the bed? Centered on the fireplace? Not awkwardly chopped at eye level? Plan a starting point so the most visible wall
looks intentional.

Pro move: Buy all rolls at once and check they match in color batch/dye lot when possible. Mixing batches can lead to subtle
shade differences that only become obvious after everything is on the walllike a prank your house plays on you.

Wall Prep: The Boring Step That Determines Everything

Here’s the truth: wallpaper doesn’t hide wall sinsit highlights them. Any bump, ridge, or crumb you ignore now becomes a
permanent “feature” once the light hits it.

Clean, smooth, and prime/sizing (yes, really)

• Clean: Remove dust, grease, and mystery fingerprints. Let the wall dry completely.
• Repair: Patch holes and dents. Sand smooth. Wipe away sanding dust.
• Prime or size: Use an appropriate primer or wallpaper sizing so the wall has consistent porosity and better
  slip during installation. It can also make future removal easier.
• Remove hardware: Take off switch plates and outlet covers. (Turn off power at the breaker if you’ll be working near live outlets.)

If you’re applying peel-and-stick, wall prep matters even more. A slightly dusty wall can cause edges to lift later, and heavy
orange-peel texture can create a “stuck… sort of” situation.

Make a Plumb Line: Your First Strip Is Your Destiny

Houses are charmingly imperfect, which is a polite way of saying your corner probably isn’t perfectly vertical. If you start
your first strip in a corner without a reference line, you may end up with a slow-motion drift that ends in a tragic mismatch
by the time you reach the last wall.

How to do it

1. Pick a starting spotoften a less noticeable corner or a spot where seams will be less visible.
2. Measure the wallpaper width and mark a point slightly less than that from the corner (so the strip can wrap a tiny bit).
3. Use a level or laser to draw a perfectly vertical (plumb) line from ceiling to floor.
4. Hang the first strip aligned to that line. Everything else follows it.

Cutting Wallpaper: Measure Twice, Cut Once, Then Add a Little Extra Anyway

Most wallpaper is hung in vertical “drops.” You’ll typically cut each drop a bit longer than the wall height so you can trim
neatly at the ceiling and baseboard.

Cutting tips that prevent heartbreak

• Add about 2 inches extra at the top and bottom for trimming.
• If the pattern needs matching, cut sequential strips and align the pattern before making each cut.
• Label the back lightly (1, 2, 3…) so you hang in order and keep the pattern consistent.
• Use a fresh blade. Dull blades tear paper and drag edges like a tiny villain.

Paste, Activate, or Peel: Getting the Adhesive Part Right

Adhesive is where wallpaper transforms from “decor” into “engineering.” Follow the manufacturer’s directions for the specific
paper you bought, and don’t improvise like you’re auditioning for a reality show.

Traditional wallpaper (paste-the-paper or paste-the-wall)

• Paste-the-paper: Apply paste evenly from center to edges. Don’t leave dry corners.
• “Book” the paper: Fold pasted sides together (without creasing) so it can relax and absorb adhesive evenly.
  Booking time varies by productfollow your roll instructions.
• Paste-the-wall: Roll paste onto the wall for one strip at a time. It’s often cleaner and reduces stretching.

Prepasted wallpaper

Prepasted paper usually needs water activation. Some products want a soak tray; others prefer spraying. Either way, the goal is
even activationno dry patches, no soggy puddles.

Peel-and-stick wallpaper

Peel-and-stick is mess-free, but it’s not “effort-free.” Clean the wall, let it dry, and consider letting the wallpaper relax
(unroll it) so it’s less likely to curl. Peel a small section of backing at the top, stick and align, then continue peeling
while smoothing downward.

How to Hang Wallpaper: Step-by-Step (Without Losing Your Mind)

1) Position the first strip

Start at the top with a small overlap at the ceiling. Align the edge to your plumb line. Once it’s straight, lightly press
it into place so you can still reposition if needed.

2) Smooth from the center out

Use a smoothing tool or wallpaper brush and work from the center toward the edges. This pushes out air bubbles and keeps the
paper from wrinkling. Go slowlyfast smoothing is how you trap bubbles like you’re collecting them.

3) Work down in sections

For longer drops, it helps to keep the lower portion folded or supported while you secure the top. Then unfold and smooth the
middle and bottom. Keep checking alignment as you go.

4) Trim the ceiling and baseboard cleanly

Press the wallpaper gently into the ceiling line and baseboard line, then trim with a sharp blade guided by a straightedge or
wide putty knife. Replace blades often for crisp cuts.

5) Add the next strip and match the pattern

Line up the pattern first, then bring the seam together. Most modern wallpaper is designed for butt seams
(edges meet, not overlap). Smooth the seam gently and wipe away any paste squeeze-out immediately with a damp sponge.

6) Use a seam roller carefully

A seam roller can help ensure good contact, especially on thicker papers. But don’t press so hard you squeeze out adhesive or
leave a shiny “rolled seam” mark on delicate finishes. Think “encouragement,” not “steamroller.”

Corners, Doors, Windows, and Outlets: The “This Is Why People Hire Pros” Zone

Inside corners

Don’t try to wrap a full strip around an inside cornerit often leads to lifting and wrinkles because corners are rarely
perfectly square. Instead, run the strip into the corner and wrap just a small amount (about 1/8 to 1/4 inch). Start the next
strip on the adjacent wall with a new plumb line.

Outside corners

Outside corners take bumps (literally), so give them a little extra care. Wrap slightly around the corner and keep seams away
from the sharp edge when possible.

Doors and windows

Hang the strip across the opening, then make relief cuts and trim carefully along the frame. Work slowly so you don’t tear the
paper. Save small offcuts for tight spots if your pattern allows.

Switches and outlets

Remove plates first. Hang the paper over the opening, then make a small X-shaped cut and trim carefully along the edges. For
safety, shut off power at the breaker if you’re working near exposed electrical areas.

Peel-and-Stick Wallpaper Tips: How to Avoid the “Giant Crooked Sticker” Look

Peel-and-stick can be wonderfully DIY-friendly because there’s no paste clock ticking. But it can also show every wobble and
every speck of dust. Here’s how to get a cleaner result:

• Start with a plumb line just like traditional wallpaper.
• Peel backing gradually (top first), smoothing as you godon’t rip off the whole backing at once unless you enjoy wrestling.
• Use a helper for tall walls; one person aligns while the other controls the roll.
• Don’t stretch itstretching can cause later shrink-back and gaps.
• Fix bubbles early by lifting and re-smoothing. Small bubbles can sometimes be pricked with a pin after the adhesive settles.

Fixing Beginner Problems: Bubbles, Wrinkles, and Misaligned Patterns

Bubbles

If the adhesive is still workable, lift that section gently and smooth again from the center out. If a tiny bubble appears
after drying, you can sometimes prick it with a fine pin and smooth it flat.

Wrinkles

Wrinkles often happen from stretching the paper or forcing it around corners. Reposition while the adhesive is wet. If it’s
already set, avoid aggressive pullingtears are not a design trend.

Pattern mismatch

If the pattern is drifting, the culprit is usually the first strip being slightly off or the paper being stretched.
Re-check plumb and avoid tugging downward. Pattern matching is a game of millimeters, not inches.

Wallpaper Removal (Because Future You Deserves Nice Things)

Whether you’re removing old wallpaper before installing new paper or just undoing a past decorating decision, removal is
usually a combination of patience and the right method for the material.

Common removal approaches

• Score + stripper solution: Especially helpful for vinyl-coated wallpaper so the remover can reach the adhesive.
• Steam: A wallpaper steamer can soften paste effectively, but use care on drywall to avoid damage.
• Peel-and-stick removal: Often peels off in large sections; gentle heat (like a hairdryer) can help soften stubborn adhesive.

If you plan to wallpaper again later, consider using a proper primer/sizing now. It can help with adhesion and make stripping easier
the next time around.

When to Call a Pro: A Very Mature and Responsible Section

DIY wallpapering is absolutely doable, but some scenarios are pro-friendly for good reasons:

• Two-story stairwells or ceilings so high they require scaffolding
• Expensive specialty papers (silk, grasscloth, fragile textiles)
• Intricate murals that must align perfectly across multiple panels
• Walls with serious damage, moisture issues, or questionable old layers

If you do hire help, you’ll still benefit from understanding the processyou’ll know what to ask, what to expect, and what “done right” looks like.

Real-World Wallpapering: of What It Actually Feels Like

The first time you wallpaper, you’ll probably start the day feeling like a fearless DIY hero. You have your roll. You have
your level. You watched exactly one video and now believe you have absorbed the skills of a professional installer through
osmosis. This is a normal stage of the process. Enjoy it while it lasts.

Then you make your first cut. It’s a little long, which feels responsiblelike ordering fries “just in case.” You climb the
ladder, line the strip up, and… it sticks. Immediately. Enthusiastically. Almost too enthusiastically. This is when you learn
the difference between “lightly tack in place” and “I have permanently bonded this paper to the wall and also my elbow.”

Next comes the plumb-line revelation: even if your corner looks straight, it’s probably lying. That tiny lean you can’t quite
see at the top becomes a full-on pattern drift by the third strip. In your head, you’re thinking, “It’s only off by a hair.”
Wallpaper hears that and responds, “Perfect. I will now be off by a mile, but slowly, so you don’t notice until it’s too late.”
The best emotional investment you can make is accepting that re-positioning is part of the job. Great wallpaper installs are
basically a series of tiny corrections.

You’ll also discover that blades are not optional. A dull utility knife doesn’t “cut” wallpaper so much as it persuades it to
tear in a jagged line that looks like you trimmed the ceiling with your teeth. The pro move is changing blades constantly,
which feels wasteful until you realize a fresh blade is cheaper than redoing an entire wallor explaining to guests that the
rough edge is “intentional texture.”

The paste stage is its own adventure. Too little paste and the edges lift like they’re trying to escape. Too much paste and
you’re wiping down seams like you’re detailing a car. You learn to love the humble damp sponge, not because it’s glamorous,
but because it prevents dried adhesive from turning your beautiful wallpaper into a shiny, sticky fingerprint museum.

And the bubblesoh, the bubbles. At first you smooth politely. Then you smooth more firmly. Then you realize you’re pushing
the bubble from the middle to the edge like you’re herding a tiny air balloon. The secret is slow, consistent smoothing from
the center outward, and lifting/re-smoothing before things set. When it finally goes flat, it’s deeply satisfying in a way
only DIY people understand.

By the end, you’ll step back, exhausted, and notice something wild: it looks good. Maybe not museum-perfect, but genuinely
impressive. Your confidence returns. You take photos. You consider doing another room. This is also a normal stage of the
process. Proceed with caution… and buy extra blades.
