Wipe the glass surface on the back of the aquarium, add a little detergent to the water (to reduce the viscosity of the glue), spray on the glass surface (do not spray a lot), or wipe with a damp cloth. 2. Peel off the corner of the background protective film, start to paste after aligning the fixed position, and apply even force slowly when pasting. If there is air bubble when sticking, you can tear it to the bubble and spray it again to re-stick and scrape. Do not slip in the order, the leaked area is easy to foam, and the bubble will not appear (4). 3. After affixing, use a squeegee or touch to check for any bubbles that are scratched. If there are bubbles, you can use a needle to open the bubble and squeeze it with a squeegee. 4. After the paste is finished, if the water is not scraped clean, the glue will turn white, peel off and blow dry with a hair dryer, and continue to stick flat. Package List 1 x Fish Tank Sticker
