The process of installing wallpaper directly influences the quality, durability, and visual consistency of an interior space. Learning how to hang wallpaper on wall is not only about aesthetics but also about technical precision, particularly when aiming to avoid visible seams and ensure long-term durability.
This article explains how to hang wallpaper, how to control seams, and how to ensure a flawless finish using correct preparation, adhesive application, and environmental control.
Why wallpaper seams appear in wallpaper installation
Visible seams are among the most common challenges when learning how to hang wallpaper, although they can often be minimised through correct preparation and application techniques,
Easy to hang wallpapers are engineered to reduce movement during installation and drying. Unlike traditional wallpapers, which may expand when exposed to moisture and contract as they dry, Aldeco wallpapers maintain a more stable structure. They combine synthetic and natural fibres in their composition, making them among the easiest wallpapers to hang.
Even so, the final result is still influenced by several factors, including adhesive performance, wall preparation, smoothing techniques, or unsuitable drying conditions.

How to hang wallpaper on wall to prevent seams: step-by-step
Understanding how to apply wallpaper is essential for achieving a professional finish without visible joins or seams. Following the correct step by step wallpaper installation process significantly improves the final appearance and helps create a seamless finish.
1. Prepare the wall before wallpaper installation
Correct preparation is one of the most important steps in how to prepare wall for wallpaper successfully.. Applying a primer helps seal the wall surface and prevents the adhesive from drying too quickly, which improves bonding and durability.
To improve adhesion:
- Use a primer that seals the surface effectively
- Avoid high gloss painted walls
- Prefer matte or eggshell finishes for better grip
To reduce visible seams in wallpaper:
- Use a primer in a colour similar to the wallpaper before installation
- Reduce contrast between wallpaper panels and the wall surface
- Seams can also be camouflaged through the banding technique, by pre-painting vertical bands where the wallpaper joints will align
For darker wallpapers, seam visibility becomes more noticeable due to contrast between the surface and the edges of the material. In these cases:
- Pre-colour wallpaper edges with water-based pencils or markers in a matching shade
- Carefully remove excess pigment with a damp microfiber cloth
2. Apply the wallpaper correctly
Proper wallpaper application is essential when learning how to put wallpaper on walls, ensuring a professional installation finish.
Smoothing the wallpaper ensures that the correct pressure is applied across the surface, improving adhesion and helping remove excess paste from the edges.
Once the wallpaper is hung:
- Smooth the surface firmly from the centre outward
- Ensure even pressure to reinforce bonding during drying
- Remove any excess adhesive immediately using a soft, clean cloth
For best results, a seam roller should be used along the edges of each panel to enhance grip and ensure a secure finish.
To avoid stretching and misalignment:
- Do not stretch wallpaper edges to close gaps
- If adjustment is needed, gently push the wallpaper from the centre so the panel can slide into position
- If required, carefully lift and reposition the panel instead of forcing the seams together
3. Allow the wallpaper to dry properly
Temperature and airflow strongly influence wallpaper performance during drying.
People frequently ask: how long does wallpaper take to dry? In most environments, wallpaper requires approximately 48 hours to dry completely.
During this period, avoid:
- Direct sunlight
- Heaters
- Air conditioning
- Sudden temperature changes
Natural drying conditions help maintain adhesion quality and reduce the risk of visible seams appearing after installation.
Bubbles in wallpaper: how to remove
Air bubbles in wallpaper are a common issue during or shortly after installation and are usually caused by trapped air, uneven pressure, or excess adhesive beneath the surface. Understanding how to remove bubbles in wallpaper is essential to maintain a smooth, professional finish without damaging the material.
In most cases, small bubbles can be corrected by smoothing the wallpaper during the drying phase without affecting overall alignment or seams, especially with easy to apply wallpaper designed for more controlled installation. However, if bubbles persist or the wallpaper has fully dried, smoothing alone may no longer be sufficient.
How to get rid of air bubble in wallpaper:
- Carefully pierce the bubble with a fine pin to release trapped air
- Gently press the area flat using a soft cloth or smoothing tool
- Avoid overworking the surface, as excessive pressure may damage the wallpaper finish or affect the surrounding area
