NAC Products’ Moisture Lock 101®is a clear, water-based, chemical hardener for porous and cementitious substrates that fills and seals pores and capillaries to harden and dust-proof surfaces. Moisture Lock 101®contains no VOCs and maximizes the coverage of NAC primers by sealing the substrate and minimizing absorption. Moisture Lock 101®will not salvage honeycombed or structurally unsound surfaces, but is an effective solution to harden and seal patching/leveling compounds, moderately hard concrete, mud beds, gypsum/gyp-crete, and lightweight concrete.
