Materials: Vinyl- Permanent wallpaper application,peel&Stick， removable， self-adhesive. waterproof and washable,easy-clean with clear water. Woven Paper(Traditional Wallpaper) - Permanent wallpaper application, requires wallpaper glue for installation, same as most the traditional wallpaper. Tip: I make wallpapers for exact dimensions. When you're not sure of your walls are perfectly straight, I recommend adding some inches extra if you don't mind cutting the wallpaper on your own. CUSTOM ORDERS I make custom sizes for FREE :) Please contact me with your sizing requirements and I will have an individual listing for your custom size. * Please note, if you need the custom size, the overall look of the mural can be slightly another than picture in the offer. Eco Certificate: I use a state-of-the-art GreenGuard-certified HP LATEX III generation printer to not only ensure the highest quality but also guarantee that the product you purchase is environmentally friendly and complies with the most stringent safety standards. If you have any questions, please feel free to contact me! Wall preparation: Before application, make sure that your wall is prepared well - the surface must be clean and completely dried. Remember to wait 3 weeks after painting the wall! Peel&Stick doesn't work on the wall painted with latex paint! However, if you already have your wall painted with latex paint, you can garnish it with sandpaper - it would make the wallpaper stick to the wall. There is also a possibility to order the wallpaper on a traditional paper material; it's not self-adhesive nor removable.
