ACE Premium Lithium Densifier is a high solids, complex blend of Lithium and other inorganic soluble silicates. When applied to concrete or masonry surfaces the silicates react with calcium hydroxide and reduce porosity and permeability of the concrete matrix. This serves to increase the hardness and chemical resistance which, in turn, increases the service life of the surface. Membrane forming sealers can be worn away in high traffic areas, leaving the unprotected concrete unsightly and susceptible to chemical attack. Since ACE Premium Lithium Densifier penetrates the concrete, it will not scratch or peel off. Concrete surfaces treated with ACE Premium Lithium Densifier can be polished with a buffing machine to achieve a high sheen. ACE Premium Lithium Densifier can also be integrated into a diamond polishing process that will result in superior gloss meter readings. ACE Premium Lithium Densifier high solids formulation is easy to apply.
