What Should The Wall Condition Be Like Before Apply Wallpaper?

• Wall Requirements: The surface must be smooth and even, as wallpaper cannot cover imperfections such as bumps or uneven areas.
• Paint Requirements: The wall cannot be painted with waterproof oil-based paint, latex paint, or textured decorative paint, as these will prevent the wallpaper from adhering properly. So, water-based paint should be used.
• Recommended Types of Paint: water-based sealer is used to prepare surfaces before wallpaper installation. It limits mold and fungus growth. It also improves the adhesion between the wallpaper and the wall paint.
