Measuring Epoxy Success
In the excellent comparison of marine epoxies in the June 2012 issue, one crucial aspect was left out of the evaluation: measuring out the ratio of resin to hardener. Get that wrong, and the whole project could fall apart, literally.
I have been using West System for about five years with excellent results; the mini-pumps make measuring a no-brainer, and the West System support system also is terrific.
The Interlux Epiglass looks interesting, but no mention was made of how to measure the proper ratio. Is it easier than the West System pumps?

The Interlux Epiglass pumps, just like the West System pumps, are calibrated for super easy mixing. With both brands, one pump dispenses the exact amount needed to get the right mixing ratio of resin and hardener, so their ease of application is pretty much equal. When using any maker’s pumps, remember that they are not infallible. Pumps have a tendency to suck air as the container volume lowers or when the prime is lost between uses. A better way to ensure mixing ratio accuracy is to use measuring cups and to mix based on the designated weight ratios of hardener and resin.
