Roof Loc 5GL PTA & B KIT

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.
Roof Loc contains a part A and part B that must be mixed together. On cement roof tiles and shingles, dilute with one part water to one part mixed sealer and apply with roller or sprayer. For best results, it is recommended to mechanically mix with a power mixer for a minimum of 2 - 5 minutes. 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 4-6 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 Roof Loc more than once every 2 years.
