When you layout your plywood for bonding do you want both surfaces smooth or somewhat rough for the epoxies to grip onto?
good question, I sanded both surfaces with 40 grit and clean, clean and clean with acetone, then apply one coat of slow resin to plywood surfaces then wait a couple of hours and apply second coat then apply thickened epoxy. It’s an important step to allow the resin to penetrate the wood fibres. If you skip this step the likelihood of delimitation is increased because, if not, the wood draws the resin from the thickened epoxy thus creating improper bonding.
hope that makes sense... thank you
