❌ 1. Applying Wallpaper on Dirty or Uneven Walls

This is the biggest mistake beginners make.

Why it’s a problem:

• Dust prevents proper adhesion

• Moisture weakens the glue

• Uneven surfaces create bumps and gaps

✔ What to do:

• Clean the wall thoroughly

• Let it dry completely

• Remove loose paint or plaster

• Fill cracks or dents before installation

❌ 2. Not Measuring the Wall Correctly

Incorrect measurements can leave gaps, mismatched patterns, or wasted wallpaper.

✔ What to do instead:

• Measure wall height & width twice

• Plan layout before peeling

• Mark guidelines using a pencil or ruler

Accurate measurement = perfect alignment.

❌ 3. Peeling Off the Entire Backing at Once

Doing this traps air bubbles and makes it hard to reposition.

✔ Best method:

Peel 10–20 cm at a time, stick slowly, and smooth out as you go.

❌ 4. Not Smoothing Out Air Bubbles

Air bubbles can ruin the 3D finish and cause edges to peel up.

✔ Solution:

Use a wallpaper smoother, cloth, or a soft card to push bubbles outward.

❌ 5. Ignoring Wall Temperature & Conditions

Wallpaper does not stick well to:

• Damp walls

• Newly painted surfaces

• Very cold or hot walls

✔ Fix:

• Wait 48–72 hours after painting

• Ensure wall is dry

• Install in normal room temperature

❌ 6. Wrong Placement Near Heat Sources

PE Foam wallpapers should be kept away from:

• Gas stoves

• High-heat chimneys

• Direct heat from appliances

✔ Tip:

Safe for dining areas & backsplashes away from direct flames.

❌ 7. Not Aligning Brick Pattern Correctly

Misaligned bricks make the wall look unprofessional.

✔ How to avoid:

• Start from the top corner

• Match each new sheet with the previous one

• Check alignment every few inches

❌ 8. Cutting Without Planning

Random cutting leads to uneven edges and gaps.

✔ Recommended:

Measure → Mark → Cut → Apply
Use:

• A sharp cutter

• A scale for straight edges

❌ 9. Using on Rough, Curvy, or Textured Surfaces

Peel-and-stick wallpaper does not adhere well to rough textures.

✔ Best surfaces:

• Smooth

• Clean

• Dry

Suitable materials include:

• Steel

• Wood

• Glass

• Plastic

• Painted walls

• Tiles

❌ 10. Ignoring Corners and Edges

Poorly applied edges can lift over time.

✔ Fix:

Press corners firmly
Use extra adhesive if needed
Trim neatly for a clean finish
