1. If you are pasting on the surface of glass or tile, because its material is relatively smooth, it is better to dry the surface with a clean rag before pasting, so that it is easier to paste, and the smoothing effect is better.2. For some larger pattern stickers, some bubbles may appear after flattening. At this time, you can use a scratch card to remove the bubbles or puncture and smooth the small bubbles with a needle tip, which will not affect the overall paste effect.3. If the pasted wall is damp, aged or just painted with new paint, it may cause the wall sticker to automatically fall off after pasting, or it may cause the wall to peel off. You can use a hair dryer to dry the wall with hot air or wait for the paint to evaporate for a period of time. I will post it later, but the effect may be different, so customers are kindly requested to choose the posted location carefully.4. If you accidentally paste the wall sticker in the wrong place, you can use a small blade to gently lift off the corner of the wall sticker and tear it off, and then paste it again. This product can be reused under normal circumstances, as long as it is not torn.
