Cobble™ Loc is two-part, water based clear sealer designed to enhance and protect concrete pavers, natural stone, stamped concrete, and other concrete surfaces. Cobble Loc achieves an enhanced appearance like traditional solvent-based sealers, in an eco-friendly, low-VOC formulation. Cobble Loc protects surfaces, provides chemical resistance, locks down joint sands, and inhibits weed growth and anthills. Cobble Loc is available in multiple finishes and with or without a nonslip grip additive.
