The image alongside shows two carpenters removing a laminate from plywood surface. One carpenter is using a flame to heat the laminate (using a kerosene blow torch), and the other carpenter is simultaneously separating the heated laminate from the plywood using a scraper like tool.
Heat helps to lessen the bonding strength of the glue, making it possible to remove the laminate. Notice the laminate pieces lying alongside. The entire laminate cannot be removed together, and has to be scraped out in small parts.
After the laminate is removed, the plywood surface is thoroughly sanded. After sanding a new laminate sheet is glued over the same plywood, and the furniture starts looking like new again.
