Diamabrush Lithium Densifier For Stone Floor Care, 5 Gallon DiamaBrush Lithium Densifier DiamaBrush Lithium concrete densifier is a 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. The result is that both the hardness and chemical resistance of the surface is increased resulting in longer service life. Membrane forming sealers can be worn away in high traffic areas, leaving the unprotected concrete unsightly and susceptible to chemical attack. Since DiamaBrush Lithium Penetrates into the concrete, it will not scratch or peel off. Concrete surfaces treated with DiamaBrush Lithium can be diamond polished in order to achieve a polish of high sheen. It is suggested DiamaBrush Lithium be applied to cement based terrazzo for increased polish life as a part of the terrazzo polishing process. General Instructions For industrial use only. Any topical coatings must be removed prior to the application of DiamaBrush Lithium. DiamaBrush Lithium may be applied to surfaces that have been treated previously with other silicate treatments. The surface must be clean and dry prior to application. DiamaBrush Lithium is ready to use and should not be diluted. It may be applied with a mop, roller, or pump up sprayer to the point of puddling. The product should be lightly agitated with a squeegee or broom till dry if necessary to prevent the drying of puddles.
