Understanding Wallpaper and Its Adhesives

Wallpaper adds character and style to any space, but over time, it can become outdated or damaged. When you decide to change your wallpaper, the challenge often lies in the adhesive left behind. Understanding the type of wallpaper glue used can help you choose the best removal method. Most wallpaper adhesives fall into three categories:

• Traditional Paste: Common in older wallpapers, this type can usually be removed with warm water.
• Strippable Adhesives: These modern adhesives allow for easier removal, but residue can still remain.
• Pre-pasted Wallpaper: This type activates with water and can also leave some glue behind when removed.

Knowing what you’re working with can guide your choice of removal method.
