Step 4 Fill your Ice Rink with Water and Let it Freeze
Time to fill your rink with water. Run a hose to the rink and hang it over the edge. Be careful not to put any hole in your tarp that would cause a leak. Let the rink fill until you have at least 2 inches of water over the entire rink. Your ground is likely not perfectly level, so you may have areas that have more water than others. It’s going to take a few hours to fill, so just sit back and wait. Once it’s full, let it freeze for about 2-3 days, ensuring that the weather doesn’t rise above freezing. Then staple the tarp to the tops of the edges and trim off the excess.
