Stalok W/A® joint sand

StaLok W/A® Jointing Sand is a product for the final jointing of pavements and slabs in unbound construction. A significantly more resistant joint seal is achieved compared to the conventional crushed sand joint - and without the risks of a rigid joint, because StaLok W/A® remains adaptable.

Tint = gray

Container = 25 kg / bag or in big bag
