Pre-pasted wallpaper has adhesive on the back that must be activated with water.

To apply it:

1. Wet the back of the wallpaper with a damp sponge or spray water.
2. Fold the wallpaper paste-side in and let it book for about 1 minute.
3. Apply it to the wall, align the panel, and smooth it carefully with a squeegee to remove bubbles.

Note: Avoid over-saturating the material and keep pre-pasted wallpaper away from high-moisture areas, because the adhesive is water-activated.
