He said the council had told the trust it was unlikely to fund the project, after hearing a submission to the annual plan.
"Unlikely doesn't mean no but it means we have to work a lot harder, that's why we need people's support."
He said he was seeking commercial sponsorship to help secure the ice rink, as well as applying to trusts to be able to pay the deposit.
Synthetic ice rinks are already used in the United States by the Florida Panthers NHL team and for recreational purposes in Brazil, Saudi Arabia and Australia. They require no water and no power.
Mr Paul hopes to have the public rink set up by Christmas and then move it to a school in February 2015. He said the rink would be available to students during the day and opened to the public, who would pay for access, in the evenings. He said there would be opportunities for people to learn ice hockey or advanced skating.
Earlier this year, he travelled to Spain to try two different synthetic rinks and he said he was "blown away" by his experience. "It far exceeded my expectations. I spent an hour and a half skating on it."
