How to Properly Install Wallpaper: A Beginner’s Guide

Wallpaper can instantly transform a room, adding personality, texture, and elegance. However, incorrect installation can lead to peeling, misalignment, or bubbles. If you’re a beginner, follow this step-by-step guide to install wallpaper like a pro while avoiding common mistakes.

1. Prepare the Wall for Installation

Proper wall preparation is key to ensuring wallpaper adheres well and lasts long.

• ✅ Clean the wall – Remove dust, dirt, and grease with a damp cloth.

• ✅ Smooth out imperfections – Fill cracks or holes with spackle and sand rough surfaces.

• ✅ Prime the surface – Apply a wallpaper primer to help adhesion and prevent damage when removing wallpaper in the future.

💡 Tip: If applying wallpaper to a previously painted wall, use a primer-sealer to create an even base.

2. Measure and Cut the Wallpaper Correctly

Accurate measuring prevents wastage and ensures seamless alignment.

• ✅ Measure wall height and add extra length (2-3 inches) for adjustments.

• ✅ Cut multiple strips at once, ensuring patterns match across panels.

• ✅ Mark a vertical guideline using a plumb line or level to keep wallpaper straight.

📌 Common Mistake: Not aligning patterns properly can create noticeable seams.

3. Choose the Right Adhesive

Different wallpapers require different adhesives. Check the manufacturer’s recommendations.

• Pre-pasted wallpaper – Activate glue by soaking in water.

• Peel-and-stick wallpaper – No adhesive needed; simply peel and apply.

• Traditional wallpaper – Use wallpaper paste applied either to the wall or paper, depending on the type.

🎯 Pro Tip: Use a wallpaper adhesive roller or brush to apply glue evenly without air pockets.

4. Applying the Wallpaper

This is the most crucial step in getting a flawless finish.

1. Start from a corner – Align the first strip with the marked guideline.

2. Smooth as you go – Use a wallpaper smoother or sponge to remove air bubbles.

3. Match patterns carefully – Align edges precisely to avoid visible seams.

4. Trim excess – Use a sharp utility knife to remove extra material at the top and bottom.

🔍 Avoid These Mistakes:

• Stretching the wallpaper too much, causing misalignment.

• Pressing too hard, which can push out glue and cause edges to lift.

5. Finishing Touches & Drying Time

• ✅ Wipe away excess glue with a damp sponge to prevent stains.

• ✅ Press seams gently with a seam roller for a smooth finish.

• ✅ Let wallpaper dry fully (usually 24 hours) before adding furniture or decorations.

🛑 Warning: Don’t rush drying! Premature handling can lead to peeling or misalignment.
