I'd start by seeing what the paver manufacturer recommends. If you
didn't put them in and don't know whose they are then take one down to
your local paver distributor and ask. [also ask for their
recommendation- they kow your weather conditions]
There is a chart here that can at least point out the many variables
that you should be aware of- [it is a commercial site & is helping you
pick which of their sealers will work where]
