I teach chemistry; I know how epoxy works.

Good, then you'll appreciate the exothermic reaction of resin and hardener is accelerated with heat and mass.

To slow down the reaction,

We counter heat (which is good at thinning the epoxy syrup) by using a slow hardener.

And to counter mass, we mix small batches and pour the resin into a flat roller tray to spread it out.

This gives you a very long working time, without ANY concern for the resin becoming thick or setting up.
You have plenty of time to apply it and remove excess resin with a squeegee.

With System Three general purpose resin with slow hardener @ 85˚ it takes 6 to 8 hours to become tacky. With MAS resin and slow hardener @ 80˚ it take 3 hours to become tacky.

You can work without feeling rushed.

I don't know the time frame with other brands.

All the best,
Rob
