Hey everyone, looking for some advice on how to properly lock in the sand between my backyard pavers (picture attached for context).
The Issue:
The joint sand continually comes loose and spreads across the patio.
I’ve cleaned it up with a leaf blower multiple times, but sand keeps migrating out of the joints.
Context: The patio is covered, so it isn't getting directly pounded by heavy rainfall, but the joints still won't stay put.
Questions:

1. Is switching to polymeric sand the right move here?
2. If polymeric sand is recommended, what is the best way to activate/cure it in a covered area where direct rain won't reach it?
3. Or would applying a joint sand stabilizer / sealer over standard sand be a better solution for a covered space?
   Appreciate any product recommendations or step-by-step tips from anyone who has dealt with this!
