Throughout the guide, you’ll also find helpful references to Mon Wallpapers categories, tools, and materials that pair well with different installation requirements.

Let’s begin.

1. Understanding Wallpaper Materials Before Installation

Not all wallpapers install the same way. Before you start, make sure you know what type of wallpaper you have.

1.1 Peel and Stick Wallpaper

  • Comes with an adhesive backing

  • Perfect for renters, nurseries, offices, and seasonal décor

  • Best for smooth, non-textured walls

On Mon Wallpapers:
Explore our Peel and Stick Collection if you prefer quick installation without messy glue.

1.2 Non-Woven Wallpaper (Paste-the-Wall)

  • The most durable wallpaper material

  • Breathable and tear-resistant

  • Easy to install because glue is applied directly to the wall

  • Ideal for long-term use in living rooms, bedrooms, and commercial spaces

  • Recommended for walls prone to minor imperfections

On Mon Wallpapers:
Our Non-Woven Premium Wallpapers are recommended for customers who want a long-lasting, professional finish.

1.3 Vinyl-Coated Wallpaper

  • High durability and moisture resistance

  • Ideal for kitchens, laundry rooms, and bathrooms

Tip:
If you choose a vinyl option from Mon Wallpapers, make sure to ventilate the room well during installation.

2. Tools You Need Before You Start

Gathering the right supplies ensures a smoother and faster installation. Here’s a complete checklist:

Essential Tools

  • Measuring tape

  • Level or laser level

  • Pencil

  • Snap-off knife or precision blade

  • Wallpaper smoothing tool or felt squeegee

  • Wallpaper seam roller

  • Bucket and sponge (for paste)

  • Clean microfiber cloth

  • Step ladder

  • Plastic sheet or floor protection

For Non-Woven Wallpapers

  • High-quality wallpaper paste (ready-mixed recommended)

  • Paint roller or brush for glue application

For Peel & Stick

  • Rubbing alcohol or wall cleanser (to remove dust and oils)

Pro Tip:
Mon Wallpapers provides installation recommendations specific to each product on the product page. Make sure to check your selected design for unique instructions.

3. Preparing Your Wall — The Step Most People Skip

Correct preparation is half of a perfect installation. Even the best wallpaper can fail if the wall is not prepped.

3.1 Clean the Wall

  • Remove dust, oils, and dirt

  • Wipe with a damp cloth or mild cleanser

  • For Peel and Stick: clean with rubbing alcohol for maximum adhesion

3.2 Repair Imperfections

  • Fill cracks and holes

  • Scrape off bumps

  • Sand uneven surfaces

  • Remove peeling paint

The smoother your wall, the smoother your wallpaper finish.

3.3 Prime the Wall (Recommended)

A wallpaper primer:

  • improves adhesion

  • prevents bubbling

  • makes future removal easier

  • ensures even absorption

Priming is especially important for:

  • newly painted walls

  • drywall

  • highly absorbent surfaces

3.4 Let the Wall Dry Completely

Moisture underneath wallpaper leads to bubbles. Always allow at least 24 hours after painting or priming.

4. Measuring and Planning Your Layout

Accurate planning ensures:

  • straight seams

  • less waste

  • perfect pattern alignment

4.1 Measure Your Wall

Measure width and height at several points. Walls are almost never 100% even.

4.2 Add Extra Space

On Mon Wallpapers, each wallpaper is custom printed to include:

  • +10 cm width

  • +7 cm height
    This ensures perfect trimming tolerance and prevents gaps.

4.3 Identify the Starting Point

For nearly all installations:

  • Start from the left side of the wall

  • Move towards the right

  • Use a laser level to create your first straight guideline

Starting straight is critical. Any tilt increases with each panel.

5. How to Install Peel & Stick Wallpaper

If your Mon Wallpapers order is Peel & Stick, follow this method:

5.1 Line Up the First Panel

  • Peel back 20–30 cm of backing

  • Align the top edge carefully

  • Use your laser or pencil line

  • Press lightly — do NOT fully stick until aligned perfectly

5.2 Smooth as You Go

Using a felt squeegee:

  • smooth from the center outward

  • remove air bubbles while moving slowly downward

5.3 Continue Peeling

Peel the backing gradually. Never peel the entire sheet at once.

5.4 Match the Pattern

Overlap edges exactly as designed. Mon Wallpapers prints precise joins, so patterns meet without gaps.

5.5 Trim Excess

Using a sharp knife:

  • trim along ceiling

  • trim along baseboards

  • trim around windows and outlets carefully

5.6 Repeat for Remaining Panels

Remember to:

  • overlap slightly when required

  • check alignment every 20–30 cm

6. How to Install Non-Woven Wallpaper (Paste-the-Wall Method)

Non-woven wallpaper is the easiest to adjust and is the most recommended by professionals.

6.1 Apply Paste to the Wall

Use a roller for large areas and a brush for corners.

Apply:

  • a thin, even layer

  • only slightly wider than the width of one panel

6.2 Position the First Panel

  • Start at the top

  • Press lightly

  • Make sure the pattern is vertical using a level

6.3 Smooth the Panel

Use a wallpaper smoother:

  • work from the center outward

  • ensure no bubbles remain

6.4 Match the Next Panel

Non-woven wallpaper allows easy repositioning:

  • slide left/right to match patterns

  • press seams lightly

  • avoid overlapping unless specifically required

6.5 Trim Excess

Use a fresh blade for a clean finish.

7. Working Around Outlets, Windows, and Difficult Corners

7.1 Around Electrical Outlets

  • Turn off electricity

  • Remove outlet cover

  • Cut wallpaper loosely around the opening

  • Trim cleanly after smoothing

7.2 Inside Corners

Always:

  • wrap only 1–2 cm of the panel around the corner

  • then start the next panel from the corner

  • corners are rarely perfectly straight, so avoid using one full piece

7.3 Outside Corners

Use slightly more overlap and press firmly with a seam roller.

7.4 Windows and Doors

  • Smooth panel over the frame

  • Cut diagonally into the corner

  • Trim clean for perfect edges

8. Matching Patterns Like a Pro

Pattern matching is where many DIY installations fail.

8.1 Know Your Pattern Type

  • Straight match: lines up horizontally

  • Drop match: offset by half a repeat

  • Free match: abstract, no alignment needed

Most Mon Wallpapers murals are straight-match, making them extremely DIY-friendly.

8.2 Always Lay Out Panels Before Installation

Unroll each panel on the floor and check:

  • sequence numbers

  • direction arrows

  • that the entire mural connects perfectly

8.3 Never Skip the Alignment Step

Even 2–3 mm error at the top becomes 1–2 cm at the bottom.

9. Fixing Common Installation Problems

Bubbles

  • For Peel & Stick: lift and reapply

  • For Non-Woven: push out with smoother

Misalignment

Always fix immediately:

  • Peel gently and reposition

  • Non-woven is very forgiving

Wrinkles

Smooth carefully using downward pressure.

Visible Seams

  • Use a seam roller

  • Do NOT stretch the wallpaper

Edges Peeling

This happens if the wall wasn’t cleaned.
Reapply adhesive (for peel & stick, use a small amount of wallpaper glue on peeling edges).

10. Aftercare: Making Your Wallpaper Last Longer

10.1 Cleaning

Mon Wallpapers wallpapers are:

  • washable

  • non-toxic

  • durable

Use:

  • soft cloth

  • warm water

  • mild soap only if needed

10.2 Avoid Harsh Chemicals

Bleach or aggressive cleaners may damage the print.

10.3 Protect from Direct Sunlight

UV rays fade colors over many years.
Use curtains or UV film in high-sunlight rooms.

11. When to Choose Professional Installation

Even though Mon Wallpapers designs are DIY-friendly, professional installation is recommended when:

  • walls are highly textured

  • ceilings are very high

  • rooms have many cutouts, windows, or architectural features

  • commercial-grade results are required

Still, 90% of customers complete installation themselves successfully.

12. Final Checklist for a Perfect Installation

✔ Wall is clean
✔ Holes and cracks filled
