Techniseal Pro Poly Sand HP Nextgel Atlantic Tan

50# Bag

For a typical installation of Belgard Dublin Cobble pavers (which are 60mm or ~2-3/8" thick) using Techniseal HP NextGel polymeric sand, you will need approximately one 50 lb (22.7 kg) bag for every 65 to 85 square feet for narrow, standard joints (1/8″ to 3/8″). For wider joints (closer to 3/4″ to 1-1/4″), coverage drops to roughly 22 to 42 square feet per 50 lb bag.
