Gel Coat Preparation
Stir container thoroughly before using. Add any additives such as Sea Hawk 7125 MEK Gelcoat Thinner., Sea Hawk Patch Aid 8185: or colorants (tints) prior to catalyzing with MEKP Catalyzer.
Clean surface with Sea Hawk Wax N Grease Killer. All surfaces must be clean, dry and free from grease, wax, oil, and other foreign matter. All surfaces must be sanded. Do not apply directly over paint.
GEL COAT PREPARATION
Shake and stir container thoroughly before using. Mix 12-15 drops of
hardener per ounce of Gel Coat (10-16 cc per quart / 40-65cc per
gallon). Gel Coat will begin to gel in approximately 10-17 minutes at 77
F. In warmer temperatures (90 F) reduce MEKP Catalyst by 20%. In cooler
temperatures (65 F) increase MEKP hardener content 100%. (maximum of
112 CC) Resin may not thoroughly cure if applied in temperatures below
Gel Coat will begin to gel in approximately 10-17 minutes
at 77 F. In warmer temperatures (90 F) reduce MEKP Catalyst (not less
than 1.2%). In cooler temperatures (60 F) increase MEKP Catalyst up to
3%. Gelcoat may not thoroughly cure if applied in temperatures below 60
Note: This time element is dependent on
material temperature, room temperature, humidity, air movement, and
catalyst concentration. Gelcoat should not be used when temperature
conditions are below 60°F, as curing may be adversely affected.
Best when applied by spray. Gelcoat 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. Spray: Airless or Conventional: 2.0-2.5 orifice tip. Use ES Manufacturing Gelcoat Spray Gun G830, ES-G100, or equivalent.
Brush/Rolling: (For smaller repairs /applications only) Solvent Resistant Roller Cover 3/16" pile (nap), smooth to medium. Prewash roller cover to remove loose fibers prior to use. Spraying recommended.
Patch Aid 8185: Add 25-33% Sea Hawk Patch Aid 8185 when applying gelcoat for small repairs, to improve the working properties of traditional gelcoat 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 Gelcoat 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.
TIP: After application, buff with 3m Rubbing Compound, and then polish with 3m Marine Finesse It II Glaze.
