It really depends on a few things. The larger the joint the harder it is to fill them properly.
If you fill them first then if and when the slabs move from temperature swings or shifting the epoxy will crack. For this reason many of our clients don't fill them. If filling before coating use our Crack Repair Epoxy Putty or for larger cracks, Epoxy Mortar. Fill the joints with sand or backer rod foam first as support ( leave about 3/8" of depth for the filler).
If you do want to fill them after then use a color matched caulk. We can supply these special order.
If they are not that big then maybe just leave them be, they are there for a reason!
