Greenlight Marine Grade Epoxy Resin System 

Greenlight Marine Grade Epoxy Resin System is the result of 15 years of epoxy resin usage and development focused on solving the common problems associated with using epoxy resin in less than optimal environments (a.k.a. your typical dusty DIY workspaces)


  • Self Leveling
  • High Surface Tension Tolerant of Small Dust Particles (greatly eliminates pinholes and fisheyes typical of epoxy sealcoats*)
  • Integrated Bubble Releasing Agent
  • High Gloss Finish
  • Easy 2:1 Mix Ratio
  • Water Resistant for all Marine Applications
  • U.V. Resistant
  • Ultra Clear Resin for Coloring with Epoxy Pigments or Tints
  • 100% Solids (Very low V.O.C)
  • Proudly Made in U.S.A

*Recommended sealcoat amount for surfboards is 3 oz. mixed resin per linear foot of board. For example, a 6'0" long surfboard would use 18 oz mixed resin (6 x 3 oz.) for excellent results.

Also minimal brush strokes leads to a better finish. Brush it out once to cover and walk away.

Ask a Question
  • Do you recommend using additive f?

    When using Greenlight Surf Supply Marine Grade Epoxy you do not need to use Additive F.

  • Does this resin produce any amine blush when it cures, or is it a fully non-blushing system? My final ("gloss") coats are epoxide, silane & cyclic siloxane-borne ceramics, so any blushing matters.

    All Amine based hardened epoxies are subject to blush. High humidity (damp) and cool environment may cause blush to happen on the surface. Slow curing epoxies are less susceptible to blush.
    If blush occurs it can simply be removed with warm water and Scotch Brite pad and wiped clean with a paper towel.

  • What is the window for re coating Marine grade epoxy with slow hardener with out sanding? Will I have to sand it after 24 hours of laminating coat?

    No need to sand the lamination at any point with the Marine Grade Resin. The seal coat will bond properly any time.

  • For how long can I stock this product without it damaging? which are the ideal conditions for keeping it (temperature , humidity , light exposure )? approximately how many shortboards cut I glass with 3 gallons kit? thank you so much

    The Marine Grade Epoxy Resin has a 2 year shelf life when kept in tightly closed containers at room temperature. If the resin temperature gets below 65F it may start to crystalize but can be heated to fully reliquify at any time.

  • 1. Can Greenlight epoxy resin be used with Resin Research Kwick Kick hardener? 2. Is combining RR epoxy resin with greenlight resin allowable?

    No you cannot mix different brand epoxies, it will not harden. You can use different epoxies on top of each other as separate operations. For example, laminate with Kwick Kick and seal coat with Greenlight Marine Grade Epoxy Resin System

  • Would this be compatible with traditional RR epoxy? For example, if I wanted to use this for my gloss coat over a traditional RR hot coat? If so, would additive F be suggested as well?

    Yes Greenlight Marine Grade Epoxy System is compatible with all other epoxies and will bond permanently to laminations with Resin Research. No Additive F is needed with Greenlight Marine Grade Epoxy System.

  • When would you use a quick curing resin vs. a slow curing resin?

    Slow Epoxy resin for beginners so you have plenty of time before it starts to cure, large projects, and pours more than 1/4" thick. Fast hardener for everything else.
