Generally speaking, it is best to scrape off all the paint on the furniture first (be careful not to hurt the surface of the furniture), and then clean up the residual ash when the paint is scraped off. If it is cleaned with water, it should be dried thoroughly before pasting, and then the dust should be wiped off with a clean rag for the second time. After doing this step, it will be much easier to paste it ~ Just use a towel to squeeze out the air between the sticker and the furniture when you paste it (similar to the method of sticking a film on a mobile phone). I hope it can help you.
