Mix resin (part A) and Catalyst (part B) at the job site, immediately prior to application. The pot life of the catalyzed resin is very short (8 to 10 min.), so only mix quantities that can be used during a 5 minute period.
The mixing ratio of Resin : Catalyst will vary with temperature. The catalyst is Armor Plate 60, methyl ethyl ketone peroxide for applications up to 1/4″ thick. Use Armor Plate 63 catalyst for applications from 1/4″ to 2″ thick. More catalyst is needed at lower temperatures, less is needed at higher temperatures. Use 1.5 to 2 oz. of catalyst for each gallon of resin. The pot life can be extended by using less catalyst.
