Gel Coat & Lamination

Once a mold is prepared and given final inspection,
the gel coat is applied in a state of the art, environmentally controlled gel coat booth. Crownline uses only the finest ingredients: Cook’s gelcoat for the base and Armorcote for acccent colors. Both are from Cook’s Composites, the industry leader, and both are very expensive due to their superior blister resistance, UV resistance, and shine.

Each gel coat is applied through its own individual spray gun to ensure color integrity. Very few manufacturers apply gel coat in this very effective and very costly manner. The initial thickness of the gel coat layer is 25-30 mils wet, which dries down to 22 mils. Other manufacturers apply only 20-25 mils, which dries down to a mere
15-17 mils.

Crownline then applies the first of two vinyl ester barriers from waterline to waterline, running the entire length of the hull, as added protection against blistering.

The mold is then taken from the spray booth to the lamination floor. All units receive a minimum cure time of 60 minutes. Most receive several hours before the lamination process begins. Other manufacturers do not allow this much set up time. At Crownline, however, we believe the overall quality and premium cosmetics of the gel coat are well worth it.

The second vinyl ester barrier coat is used as a glass print barrier. It is applied and allowed a cure time of 30 minutes.

Next, 100 mils of hand rolled chopped glass and spray core are applied.

This third barrier receives a minimum cure time of 45 minutes. Bulk skin is then applied.

This time proven lamination method prevents print through, ensures void free reinforcement areas, and helps guarantee that the cosmetics on the exterior gel are impeccable.
