Application Guide - Below Waterline Application Systems

All substrates (except aluminum)

Note: Regardless of which system is chosen below, the final priming coat must always be Hullgard Epoxy Primer.

Following suitable surface preparation, the below method is suitable for all substrates:

  1. a: Apply multiple coats of Hullgard Extra to achieve 4 mils (100 microns) DFT. If applied by airless spray, 1–2 coats will be required. The additional reduction required for air atomized or roller application may require 1–2 additional coats to achieve 4 mils (100 microns) DFT.

    Allow 2 hours between coats at 77°F (25ºC), 50% R.H. Hullgard Extra allows recoating with itself at any time up to 6 months without requiring sanding. The aged Hullgard Extra must be thoroughly cleaned and free of all foreign material before recoating with additional coats.

b: Apply multiple coats of Hullgard Epoxy to achieve 4 mils (100 microns) DFT. If applied by airless spray, 1–2 coats will be required. The additional reduction required for air atomized or roller application may require 1–2 additional coats to achieve 4mils (100 microns) DFT.

Allow 2 hours between coats at 77°F (25ºC), 50% R.H. Hullgard Epoxy allows recoating with itself at any time up to 6 months without requiring sanding. The aged Hullgard Epoxy must be thoroughly cleaned and free of all foreign material before recoating with additional coats.

  1. Apply multiple coats of Hullgard Epoxy to achieve 10 mils (250 microns) DFT. If applied by airless spray, 2–3 coats will be required. The additional reduction required for air atomized or roller application may require 1–2 additional coats to achieve 10 mils (250 microns) DFT.

  2. Apply Awlstar Gold Label as soon as the last coat of Hullgard Epoxy is barely tack free, about 2 hours at 77°F (25ºC), 50% R.H.

Awlstar Gold Label can be applied by airless spray, brush or rollers. For maximum antifouling performance and protection, apply sufficient coats for 27 mils (675 microns) total wet film thickness to give a total of 12 mils (300 microns) dry paint film.

To provide a built–in indicator of when it is time to renew your Awlstar Gold Label, apply the first coat in a different color from the remaining coats. When you can see the first color showing through, it is time to renew.

Extra protection and more uniform wear properties result when 1 or 2 extra coats are applied to high wear areas, such as the bow, rudder, leading edge of the keel, stabilizers, cavitation plates, propeller cavitation areas and trim tabs.

Allow a minimum of 5 hours at 77°F (25ºC), 50% R.H. after the application of the last coat of Awlstar Gold Label before launching. Allowing 24 hours before launching is preferred.

Cooler temperatures will require longer cure times between coats and before launching.

DO NOT apply or attempt to cure Awlstar Gold Label or Hullgard products at temperatures below 55°F (13ºC).

Use antifouling paints safely. Always read the label and product information before use.
