1. If you paste on the surface of glass or ceramic tile, because its material is smooth, it is better to dry the finish with a clean rag before pasting, so that it is easier to paste and has a good leveling effect 2. Some large pattern stickers may have some bubbles after being flattened. At this time, you can use a scraper to remove bubbles or use a needle tip to puncture and smooth small bubbles without affecting the overall pasting effect 3. If the pasted wall is wet, aged or has just been painted, it may cause the wall sticker to fall off automatically after pasting, or cause the wall to peel off. You can use a hair dryer to dry the wall or wait for the paint surface to volatilize for a while before pasting, but the effect may be different, so please carefully select the pasting position 4. If you accidentally paste the wall sticker in the wrong position, you can gently tear off a corner of the wall sticker with a knife and then paste it again. This product can be reused under normal conditions as long as it does not tear
