ZincroniteTM Reinforced Acrylic Shell


The spa shell is the most expensive part of your spa and it is the one part that can not be replaced. The integrity of the shell is one of the most important aspects of your purchase. In 2007, we introduced our exclusive ZincroniteTM acrylic shell reinforcement, which provides the best solution available in the industry.
The shell has four parts: the acrylic skin, a bonding agent, a reinforcing compound and foam insulation. The industry standard is to reinforce the acrylic skin with fiberglass; however, this process can be subject to delamination and warping. Some spa manufacturers address this by using a thicker layer of fiberglass, which helps, but there is still a risk of delamination from the acrylic skin.
ZincroniteTM is a proprietary blend of acrylic bond sprays that is dramatically stronger than fiberglass and creates a permanent bond to the spa’s acrylic skin. ZincroniteTM offers unmatched strength, durability and longevity. To ensure we protect your investment, we use not one but two layers of ZincroniteTM, so you can have a beautiful spa you will be proud to own for many years.
