Mix Epoxy

Now that the core has been routed out with the #115 & #654 bits it's time to mix some epoxy. With West System they use metered pumps. Until you get good I don't recommend partial pumps. The mix ratio is a one pump hardener to one pump resin ratio. You will have about 20 minutes of pot life using the 105 resin and 205 hardener at temps in the low to mid sixties, which is plenty. At room temp, 72 degrees, you'll have 9-12 minutes of workable pot life.


Epoxies kick off faster when it's warm and slower when cold. If working in colder conditions remember that it will become more viscous and tougher to work with especially when you need it less viscous to fill deck holes.. For more info on using West System epoxy visit their great and informative web site.
