Moisture Lock 101®


Moisture Lock 101® is a clear, water-based chemical floor hardener for porous, cementitious substrates that reacts with the free lime and calcium carbonate in concrete, to fill and seal pores and capillaries to harden and dust proof surfaces.

Moisture Lock 101® maximizes the coverage of NAC Primers by minimizing absorption into porous, cementitious substrates, such as absorptive, moderately hard concrete, mud beds, gypsum, gypcrete, lightweight concrete and patching/leveling compounds.

Moisture Lock 101® has a 10-15% porosity reduction, however it will not salvage honeycombed or structurally unsound surfaces.

Application:
Moisture Lock 101® can be applied evenly with a roller, brush or squeegee. Bubbling indicates activation of Moisture Lock 101® into substrate. Up to (but no more than) three applications may be required.

After first or second application, white crystals may develop if surface has already reached maximum hardness. If this occurs, flush surface liberally with clean, preferably hot water while rapidly brushing floor with a stiff bristled broom. Mop up excess water, solutions and puddles.
