Surfaces must be clean and free of any contaminants before sealing. Concrete should cure a minimum of 28 days before sealing. On smoothly troweled concrete, an acid etch is recommend using muriatic acid.Cobble Loc contains a part A and part B that must be mixed together. On pavers, dilute with one part water to one part mixed sealer and apply with roller or sprayer. Apply a uniform coat heavy enough to wet out joints if sand stabilization is desired. A second coat of sealer may be appropriate depending on the porosity of the substrate. The 2nd coat can be applied after 2 hours of dry time. As a topcoat over Coloron, Colorcrete or TD One Step, apply a uniform coat undiluted by water. To avoid buildup of sealer, do not apply Cobble Loc more than once every 2 years.
