Gemini's EWH5, is a hardener specially designed for Gemin Evo Eclipse products. Available only in 1 liter size. Adding hardener will increase the gloss by approximately 3-5 degrees more, and will also slow the drying time. Add 5-10% of hardener by weight or volume (6-12 oz. per gallon) and mix thoroughly. After hardener is mixed in Evo Eclipse, the pot life is 1-2 hours depending on the air temperature.

Also, recommended for Sirca 1K & 2K products listed with Hardener 6CW1S02, as this hardener gives a longer pot life to work with.
