How to read epoxy application data

[zboss]

Hello,

The epoxy application data for Pettit high-Build Epoxy reads:

Substrate Temp To Recoat To Bottom Paint To Launch*
90°F 2hrs-14 days 3-6 hrs 48 hrs min
70°F 3hrs-14 days 5-8 hrs 72 hrs min
50°F 6hrs-14 days 7-10 hrs 120 hrs min

For the column "To bottom paint"... does this mean that bottom painting MUST begin 5-8 hours (assuming 70 degrees) after the last coat of epoxy has been applied?

Generally it avoids sanding for "tooth".... But remember epoxy will have an amine blush that needs to be removed prior to paint. Wipe ONE DIRECTION with a lacquer thinner soaked wiper.
