The distressing process for kitchen cabinets can vary depending on several factors, such as the size of the cabinets, the extent of distressing desired, and the specific techniques used. Generally, the distressing process can take a few hours to a couple of days. This is because it involves sanding, scraping, applying paint or stain, and allowing drying time between each step. However, the complexity of the distressing technique and the number of distressed cabinets will also impact the overall time. Therefore, it's best to plan accordingly and allocate enough time to complete the distressing process with attention to detail.
