Maintenance Level Guidelines
5. It is important to hold the nozzle of the hose or water canon high, rather than parallel to the ground or downward, enabling the water to be cooled by the air before it reaches the ground. The operator should avoid dragging the hose along newly sprayed ice or allowing it to lay on the ice for any length of time in one spot because it will roughen or melt its way into the rink. 6. When spraying, there should be little or no water standing on the rink when the work is completed. It may be necessary to take a 5- to 10- minute break in between coats for the water to freeze before spraying again. Under ideal conditions, the water should be applied while the surface is lightly wet or “tacky”. 7. The dikes or snow banks should receive the same treatment as the surface. 8. As soon as 1 to 1½ inches of ice is built up or secured over the rink, the area may be scraped to cut off any bumps or grass blades that stick through the ice, and to obtain as smooth a surface as possible upon which to build. 9. When using the truck-mounted water cannon, a figure eight pattern should be followed, which enables the hose to be pulled by the truck without having to move it by hand. 10. Spraying should not be undertaken when it is snowing or it is felt the water will not freeze, prior to a forecast snow. 11. On any turf area, it will take 2 to 3 nights or 20 hours of spraying to build up 1½ to 2 inches of ice suitable for skating. Hard surface areas require 2 inches minimum depth for skating. Work to build up 4-6 inches of ice as early in the season as possible. 12. When spraying hard surfaces (i.e., blacktop or tennis courts) it is desirable to lighten the surface to facilitate freezing, since a dark color absorbs heat, whereas light colors reflect it. Procedure is to cover the surface with a layer of lime or marble dust applied with a fertilizer spreader. Care should be taken not to disturb the layer when initially spraying.
