How are the markings applied to the ice?
The ice is built up to ½” thick by spraying water over the concrete floor, which has the freezing pipes imbedded. White paint is applied to the entire surface (the ice doesn’t look white just because it’s ice – it’s mostly translucent), and the blue lines, red line, goal lines and other markings are painted on. Additional water is then built up over the markings, until the ice reaches it’s prescribed thickness.
