I have seen the ads and display of polymeric sand for paver joints. I am using 6x9 concrete paver with just regular paver sand. This is my first time doing this so I don't know if I will regret few years later as the sands got washed out. I live Pacific Northwest so there is a bit of rain but not like heavy water rain, more like shower continuously.
My questions are:
How long the regular sand supposed to last? Any long term success story here?
Is it easier to apply sealer instead of replacing the current sand (using pressure washer) and put in polymeric sand? Replacement seems like a tiring job in the future.
