Low grain sanding paper is used in this process. This laminated veneer lumber is once again final sanding. The different production company uses its techniques of Steaming. This process usually lasts for 48 hours or more depending on the wood species. High heat and pressure are used along with chemical steam. Inside the cylinder, logs are inserted and chemicals are sprayed. To perform this process, a large vessel or a vacuum tube cylinder uses, In this process, chemicals and water vapor are exposed to the log.
