Layering Epoxy molds, timing.
How long can I wait between layers when laying up a new mold using thin epoxy? Can there be 24 hours between layers, or do I have to get the next layer on while still tacky? Trying to decide if I want to build the mold over several days next week, or wait until the weekend to do the one side in one day like I have been. It is a two part mold which means it will take 2 weekends to make, one day to wait, then a day or two to cure. Going to be using a 5:1 thin epoxy similar to West Systems, non waxed.
