What technique is used for ice resurfacing?

The technique for ice resurfacing that is widely accepted and most effective is wet scraping followed by a thin layer of water application. This method is crucial for maintaining the quality of the ice surface in any ice facility.

Wet scraping involves using a tool that removes the top layer of the ice, which can become rough or pitted due to usage, and as it does so, it also adds a small amount of water to the surface. This combination helps fill in small imperfections and creates a smoother finish. The thin layer of water applied afterwards acts as a sealant, bonding with the existing ice and further enhancing the ice surface quality. This process not only improves the playability of the ice by creating a faster and smoother surface but also helps prevent the formation of cracks or holes that can affect skaters.

While the other techniques listed may contribute to ice maintenance in specific scenarios, they do not offer the same comprehensive benefits that wet scraping followed by water application provides. A hot scraping method could be effective under certain conditions but lacks the consistency that comes from the proper moistening of the surface afterward. Dry scraping is less effective for creating a smooth finish as it does not provide any means to fill in imperfections. Chemical resurfacing may have its applications, but it doesn't
