Please wear gloves to prevent the glue from touching the skin!) The corner installation needs to be 5.4mm away from the wall so that it can be close to the wall. .1. First wipe the installation wall with detergent and water, and then wipe it with a clean damp cloth to keep the wall dry.2. Paste the sticker vertically along the wall (no need to press tightly, it is easy to tear off after the shelf is installed).3. Apply glue evenly and thickly on the blank space behind the back panel (all the glue is used up).4. Tear off the protective film of the backplane, and stick it along the edge of the auxiliary sticker (not on the auxiliary sticker) and press it with both hands to ensure that the backboard matches the wall.5. After waiting for 72 hours, the glue solidifies, and first lock the screw at the lower end of the spindle tube (it is not necessary to lock it first, which is convenient for subsequent installation).6.
