Hello, we're sorry to hear you weren't thoroughly satisfied with your purchase of our Calypso Royale Kit. We take customer feedback seriously, as we are constantly trying to improve. Our adhesive should have no issue holding the material in place during the curing process, meaning braces should not be required. It sounds like there may have been some additional circumstances going on to hinder adhesion. Please give us a call at 877-941-3662, and we'd be happy to discuss any concerns you may have.
