Info & Guides

NOTE: TotalBoat Crystal Clear Hardener combined with TotalBoat Traditional Epoxy Resin has similar performance and finish characteristics as West System 207 Special Clear Hardener paired with West System 105 Epoxy Resin. However, for the clearest finish, we recommend the TotalBoat High Performance 2:1 Epoxy System.


Directions: TotalBoat Crystal Clear Hardener can be dispensed by pouring.

Surface Preparation: All surfaces must be clean, dry, and free of any surface contamination. Light sanding is recommended, followed by an oil-free solvent wipe, or a lint-free rag dampened with isopropyl alcohol or plain water to remove dust.

MEASURING: NOTE: THE MIX RATIO IS DIFFERENT THAN TRADITIONAL TOTALBOAT FAST AND SLOW HARDENERS. There are two ways to measure: (1) BY VOLUME: Measure THREE parts TotalBoat Epoxy RESIN to ONE part TotalBoat Crystal Clear Hardener, or (2) BY WEIGHT: Measure 100A:27B.

MIXING: Mix for 1-2 minutes, then add any desired fillers, if needed. The catalyzing of TotalBoat Epoxy is an exothermic (heat-producing) reaction. The peak exotherm will vary according to ambient temperature and choice of hardener.

Eye/Skin Protection: Wear protective eye wear, suitable gloves, and protective clothing.

NOTE: This container will not come filled to the top. It contains the calibrated amount of product to work in conjunction with the same size resin container.

My Favorite
By Jeremy NewMusic Guitars from Columbia Mo

I've used a lot of different clear epoxies and this one is easy superior. Mixes well, cures wonderfully. Quite hard. This will be my primary resin from now on.

Bottom Line Yes, I would recommend to a friend
