You'll need to wait for however long the cure time is specified on the sealant. If BobbyG says 12 hours then 12 hours as he is the resident Powerlock expert. I use BFWD as a sealant and wax or second coat the next morning.
Since you really do not have weather issues I'd seal it then the following week or whenever wash and throw the wax on.
