Preparation: Make sure all of the surface areas are clean and free of any contaminants. They should be dry and sanded smooth for ideal bonding conditions. Make sure to clean off all sanding dust once finished. Keep room temperatures between 60 - 80F degrees with humidity under 85% for optimal working conditions.

Mixing Procedure: Mix the Hardener and Resin at the specified mixing ratios. Mix with stir stick for 1 to 3 minutes until mixture is fully blended without strands of unmixed material remaining. Be sure to thoroughly scrape the bottom and sides of container to ensure all product is mixed completely. Always use clean and dry tools when mixing epoxy. Marine Epoxy temperatures should not be below 60°F when mixing.
