Before leafing, we apply primer and a copper paint as our leafing base. We allow this to sit for two to three days in natural atmospheric conditions before preparing the tub for our leafing specialist to hand apply the solid copper leaf. Again we allow the tub to sit for a further two to three days while the copper slowly begins its' natural aging process. Over the next few days, we gradually introduce new layers of special solutions to expedite the weathering process. After this, it's back to the natural external forces for a further few days. Using a special neutralizing solution, we wash the entire tub exterior before coating with four heavy layers of high grade gloss clear lacquer. The lacquer not only protects and seals the surface, it almost illuminates the gorgeous colors and hues of the tub exterior.
