Patch Aid 8185: Add 25-33% Sea Hawk Patch Aid 8185 when applying gel-coat for small repairs, to improve the working properties of traditional Gel Coat spray patches.
Wax Additive: Do not add wax additive if using Patch Aid. Path Aid already contains a wax additive. If not using Sea Hawk 8185 Patch Aid, then you may add up to 4oz of Sea Hawk 8140 Wax Additive per gallon for tack free surface on final coat.
Tinting: Sea Hawk Gel Coat may be tinted using Sea Hawk colorants designed for use in Sea Hawk resins and gel coats. Do not use more than 1 oz tint per quart.
Catalyzing Gel Coat with MEKP: The catalyst level (MEKP) should not exceed 3.0% or fall below 1.2 for proper cure. Ideal range is 1.8% @ 77°F. Gel time at 1.8% MEKP is 10-17 minutes. This time element is dependent on material temperature, room temperature, humidity, air movement, and catalyst concentration. Gel Coat should not be used when temperature conditions are below 60°F, as curing may be adversely affected. See Catalyst mixing ratios.

Stir container thoroughly before using. Add any additives such as Sea Hawk 7125 MEK Gel Coat Thinner, Sea Hawk Patch Aid 8185, or colorants (tints) prior to catalyzing with MEKP Catalyzer.
- Surface Preparation
Gel Coat over clean, dry surfaces. Remove all grease, oil, wax, or other foreign material by using Sea Hawk S-80 Wax N Grease Killer. All surfaces must be sanded. Do not apply directly over paint.
- Application
Best when applied by spray. Gel Coat delivery rate of no more than 2.5 pounds per minute with conventional air atomized spray, and no more than 4 pounds per minute with airless equipment. For more detailed gel coat application please go to www.seahawkpaints.com/Gel Coat.
- Limitations
Apply in good weather when air and surface temperatures are above 60°F (16°C). Surface temperature must be a least 6°F (1°C) above dew point. For optimum application properties, bring material to 70-80°F (21-27°C) temperature range prior to mixing and application. Unmixed material (in closed containers) should be maintained in protected storage between 40° and 74°F (4-23°C). Prolonged atmospheric exposure of this product may detract from performance and reduce shelf life. Technical and application data herein is for the purpose of establishing a general guideline of the coating and proper coating application procedures. As application, environmental and design factors can vary significantly due care should be exercised in the selection, verification of performance, and use of the coating.
- Application Data
- Mixing: Stir container thoroughly before use. Do not over mix.
- Thinning: If necessary, maximum 10%Sea Hawk 7125 MEK Gel Coat Thinner. Do not thin when using Patch Aid 8185.
- Clean Up: Acetone or MEK
- Pot Life: 10-17 Minutes depending on atmospheric conditions and MEKP Catalyst Ratio.
- Brush/Rolling: (For smaller repairs /applications only) Solvent Resistant Roller Cover 3/16” pile (nap), or Natural bristle brush. Spraying recommended.
- Spray: Airless or Conventional - 2.0-2.5 orifice tip. Use ES Manufacturing Gel Coat Spray Gun G830, ES-G100, or equivalent.
- Safety: Prior to use, obtain and consult the “Safety Data Sheet” of this product for health and safety information. Read and observe all precautionary notices on container labels.
