I got off the phone with the people at SEM and they told me i didn't have to prime within the 24hour window but i needed to scuff or sand the seam sealer before I prime it. it is just easier to scuff it within the 24 hour window. And they did recommend epoxy primer for my use but also said i could use urethane if i need to sand it smooth. I hope this helps anyone else that has similar issues.
