I have built a bunch of rinks when the kids were younger.

I used silage tarp for a liner, it was generally cheaper than The purchased liners.

My rink was 30ft x 30ft. One roll lasted 3 seasons.

Flood, it is so important to have a single non-stop flood. Pick a night where it is going to be cold over night like real cold. Start the flood in the afternoon and let it run until it is full enough. Then leave it to freeze overnight.

When you are done flooding being the hose into the garage. You will need it again and again to “re-surface flood” and it can’t be frozen solid.

Don’t worry about changes in Calgary temps, once the rink if frozen it will hold up surprisingly well.

Also key is lighting, you need a couple of light so the kids can use it at night.
