 THE SMART CHOICE FOR YOUR EVERYDAY INSTALLATIONS 

 Install flagstone, natural stone, and large-format slabs the smarter way with Techniseal NOCO No Compaction Polymeric Joint Sand. This 50 lb bag is the first true alternative to mortar and stone dust — a next-generation polymeric joint that requires zero mechanical compaction, handles joints from 1/4" up to 4" wide, and cures into a rock-solid, flexible, and weed-free joint.
