How to Hang Wallpaper Like a Pro – Step-by-Step Instructions for Beginners and DIY Experts

Introduction: Why Wallpaper Is Back

Wallpaper is making a huge comeback in modern interiors — from subtle textures to bold patterns, it instantly transforms a room without major renovation. But the key to a flawless wallpaper finish lies in the installation process.

This complete guide will walk you through every step of wallpaper installation — including tools, prep, pasting, trimming, and expert tips — to help you achieve a beautiful, long-lasting result.

Step-by-Step Instructions for Beginners and DIY Experts

1. Types of Wallpaper: Know What You’re Working With

Before you begin, identify your wallpaper type:

Peel & Stick – Easy to apply and remove, great for renters and temporary décor.
Pre-Pasted – Backing is pre-glued; you just activate with water.
Unpasted (Traditional) – Requires separate paste; most customizable and durable.
Vinyl-Coated – Moisture-resistant and easy to clean; ideal for kitchens and bathrooms.
Fabric or Textured – High-end finish but requires more careful handling.

👉 Pro Tip: Check the manufacturer’s instructions for your specific wallpaper roll before starting.

2. Tools & Materials You’ll Need

Essential Tools:

Measuring tape
Level or plumb line
Pencil
Sharp utility knife or snap-blade cutter
Wallpaper smoother / plastic squeegee
Seam roller
Wallpaper paste (for unpasted wallpaper)
Paint roller or brush (for applying paste)
Sponge & clean cloths
Bucket of water
Step ladder

Optional but helpful:

Wallpaper pasting table
Laser level
Wallpaper primer/sealer
Painter’s tape
Drop cloth

3. How to Prepare Your Walls

Proper wall prep is crucial for wallpaper to stick properly and look flawless.

Steps:

Remove old wallpaper if present.
Clean the wall thoroughly — remove dust, grease, or stains.
Repair cracks or holes using spackle or filler. Sand smooth.
Prime the wall with wallpaper primer or a diluted glue mix. (Helps adhesion and future removal.)
Allow the wall to dry completely.

💡 For bathrooms or kitchens, use a mold-resistant primer.

4. Measuring and Cutting Wallpaper

Measure First:

Use our Wallpaper Roll Calculator to determine how many rolls you need.
Mark a vertical guide line using a level or plumb line, 1 roll-width from the corner — this ensures each strip hangs straight.

Cutting:

Measure wall height and add 4 inches extra (2 inches at top and bottom) for trimming.
If using patterned wallpaper, account for pattern repeat when cutting each strip.

5. Applying Wallpaper Paste (or Activating Adhesive)

For unpasted wallpaper:

Lay the strip face-down on a pasting table.
Use a brush or roller to apply an even coat of paste, edge to edge.
“Book” the paper: fold pasted sides together (without creasing), and let it rest for 5–10 minutes to activate and soften.

For pre-pasted wallpaper:

Submerge the strip in lukewarm water.
Let the adhesive activate, then “book” the strip for a few minutes.

For peel-and-stick:

Simply peel off the backing as you go. Clean surface thoroughly before applying.

6. Hanging the Wallpaper

How to Hang:

Start at your marked vertical guideline.
Line up the top of the strip with the ceiling, leaving 2 extra inches to trim.
Press wallpaper onto the wall, smoothing from the center outward.
Use a wallpaper smoother or squeegee to remove air bubbles.

Tips:

Don’t stretch the wallpaper — it may shrink back when dry.
Work slowly to avoid creases or misalignments.

7. Matching Patterns Like a Pro

Match patterns at eye level before smoothing the strip fully.
Adjust the next strip up or down to align the design perfectly.
Use the pattern repeat measurement (from product label or calculator) when cutting strips.

8. Trimming, Smoothing & Final Touches

Use a straight edge and sharp utility knife to trim excess at the top and bottom.
Roll over seams lightly with a seam roller to flatten edges.
Wipe away excess glue with a damp sponge immediately.

Let the wallpaper dry for 24 hours before moving furniture back.

9. Dealing with Obstacles (Windows, Doors, Outlets)

Windows/Doors: Let the paper overlap the opening, then trim carefully.
Outlets/Switches: Turn off power. Loosely cut around fixtures, then trim neatly after smoothing.

👉 Always smooth before cutting to avoid tearing.

10. Common Mistakes to Avoid

❌ Not measuring your walls properly
❌ Ignoring pattern repeat
❌ Skipping wall primer
❌ Not booking pasted wallpaper
❌ Applying wallpaper over damp or dirty walls
❌ Rushing — slow and steady wins!

11. Maintenance & Cleaning

Vinyl wallpaper: Wipe with a damp cloth or sponge.
Fabric/textured: Gently dust with microfiber cloth.
Avoid using harsh chemicals or abrasive materials.
