Method of Ice Rink Construction Whether to flood or spray ice skating areas is a perennial controversy and one that probably has no positive solution. Flooding is quicker, easier and less expensive. On the other hand, when spraying and building up protective thin layers of ice, a firm bond between the ice and ground is assured, thus eliminating air pockets and water seepage that tends to make the ice sag and crack. A. Flooding 1. When the flooding method has been selected, a bank or dike to retain the water is necessary. When an area is to be flooded, drainage outlets must be sealed carefully to prevent the water from seeping away. 2. The ground should be well frozen to a depth of 6 inches. No more than 2-3 inches of water is applied at the first flooding and must freeze to the bottom before the second flooding. 3. Temperatures for flooding shall be in the range of 15 ° F to -5 ° F. To prevent the warmer water from drawing the frost out of the ground, the nozzle of the hose shall be placed on a wooden splashboard. Splashboard should be moved every 15 minutes. 4. The flooding process shall be continued until the ice is at least 6 inches thick with no more than 3 inches applied at any one time. B. Spraying General procedures for spraying ice skating areas are outlined as follows: 1. 15 ° F to 18 ° F is ideal for spraying, as water flows out and freezes smoothly. 25 ° F is the maximum temperature that spraying can be undertaken. Very low temperatures (below 5 ° F for finish coats) freeze the water rapidly but will produce lumps and cracks if care is not taken to spray out water in even layers. 2. Check hoses for leaks. Leaky hose joints will damage the ice skating surface. 3. When laying down the first coat, the water should be applied so the frost will not be drawn out of the ground. Spray several light layers, building up the surface with film-like layers. 4. The operator should start at the end of the rink farthest from the water supply or play the wind if it is blowing, and work across the rink, back and forth walking backward toward the opposite end, with a man behind him to pull the hose. If possible, keep the hose completely off the ice to assure a smooth surface.
