Wax additive is added to the final layer of gelcoat (without wax) or to the polyester laminating resin (without wax) on the final layer of a wet layup to produce a tack-free surface, and allow the material to cure to a hard finish. When youāre building up the layers in a wet layup application, you donāt want wax in the polyester resin because you want the layers to bond chemically, resulting in a stronger bond. Itās only the final layer that needs wax additive in order to cure. The wax creates an air barrier so the resin can cure to a tack-free state ready for sanding and finishing.
Directions for Using Wax Additive
This additive contains paraffin and styrene. When adding it to gelcoat, you must also add the MEKP (methyl ethyl ketone peroxide) hardener.
The chart below indicates how much additive to add to wax-free gelcoat or polyester resin. Avoid using too much wax as it will result in fish eye and other undesirable results.
| Amount of Gelcoat or Polyester Resin w/o Wax | Ā Quantity of Wax Additive Required |
| 1 ounce | 20 drops |
| 16 oz. (1 pint) | 1/4 ounce |
| 32 oz. (1 quart) | 1/2 ounce to 1 ounce |
| 1 gallon | 4 ounces |
