: Larry, getting a handle on epoxy stuff with only time doesn't work, temps
: and time. Without knowing the temperature the times could be off by a lot.
: I could be wrong but with Systems three I think the mechanical bond may
: require washing before sanding. Any Systems three experts out there?

We're building in the den, so the temp stays constant at around 70 or so. Pygmy's instructions call for saturation, fill the next morning, fill again the next morning. We did the saturation on Monday, first fill on Wednesday, second fill on Friday. The coats were pretty thin, but the coat on Friday still gives under finger pressure.

I think we'll sand lightly and wash it down before putting on the final coat today. Thanks for all the input.
