Techniseal NOCO No Compaction Polymeric Sand 50 lb – Joints to 4"

Worked like a dream!

Best product

This is far superior to any other products we have tried on our patio.

Great product, so far looks and works as advertised

Great product, easy to apply and looks great. Had gaps in my flagstone from 1/2inch to 4 inches or so and it filled them in great. All the work is in the prepping....clearing out that gaps, killing weeds, putting a plastic border down to act as an edge. I am not a professional, just a homeowner that enjoys home improvement projects and this definitely improved the back patio firepit seating area
