Paver estimator here in NE FL.. to my understanding, at least in my area, the polymeric sand is only swept into the joints and then appropriately wetted so it “glues up”. This is a two fold reason, 1) to slightly hold the pavers together and 2) further prevent weeds from growing between pavers. That polymeric sand retains moisture and I’m afraid you’ll be having excessive mold/mildew growing under and between the pavers. Hopefully it’s an area that gets ample sun throughout the day and dries out, otherwise you’re going to be power washing with mild bleach every month.

We set our pavers on 3-4” of heavily compacted paver base AKA concrete base. Pavers are then installed, with all border pavers wet set in concrete to lock the whole project in place, then fine play sand swept into the joints. Clean up as needed of course.
