"Wet out all bond lines with un-thickened epoxy. You want the epoxy to penetrate all surface porosity and the sanding tooth. The epoxy you use to wet out should fairly thin, such as a layup resin. If you are using a thick 1:1 laminating resin to wet out with, thin it, after mixing, by 50% with denatured alcohol.

Allow the wetted out bond lines to tack up before proceeding. Depending on the ambient temperature and type of catalyst used, this should be between 2 and 6 hours. When touched, no visible epoxy should be on your finger, but the finger should be sticky now. Call it the "sticky finger test"...
