Alberta engineers design homemade Zamboni for outdoor rink This is like building a bathtub. Do what’s necessary to dam the water in.
A plastic liner will keep the water in and level.Use cold water for the first flood. Start at the lowest spot. Stop when the water is level and allow a sufficient amount of time for the water to freeze.The following floods should be with hot water.
You will want to do thinner layers, once a day. This allows old and new ice to bond and strengthen. In about a week — or two to three inches of ice — the rink should be ready for some family fun!
