LITHIUM concrete densifier and chemical hardener compound is a ready-to-use, colorless liquid, formulated with chemically reactive raw materials to harden and dustproof concrete. When properly applied, LITHIUM will offer substantial improvement in abrasion and chemical resistance and will significantly improve the durability of the concrete surface when compared to untreated concrete. As LITHIUM is applied and penetrates into the concrete surface, a chemical reaction takes place, producing a byproduct that fills in the pores of the concrete. This process produces a substantially denser concrete surface with enhanced durability. In addition to the densifying and hardening action, LITHIUM also solidifies the concrete, eliminating dusting and pitting.
LITHIUM is recommended for use wherever hardened, dustproofed, and improved chemical and abrasion resistant surfaces are required. Ideal applications include floors in industrial plants and warehouses, storage silos, sewage plants, chemical processing facilities, refineries, and heavy pedestrian floor traffic areas, such as civic centers, sports arenas, stadiums, hospitals, airports, and museums. LITHIUM can successfully be used in conjunction with shake-on hardeners.

Mixing…For optimum performance, gentle mixing or agitation is recommended.
For optimum results on fresh, newly placed concrete, use MED-CURE™ curing aid from W. R. MEADOWS immediately after final finishing operations have been completed. Apply LITHIUM according to the “EXISTING” concrete directions a minimum of 10 days after placement of concrete.
Surface Preparation…Fresh Concrete: On newly placed concrete, LITHIUM can be applied, as you would a cure, after final troweling.Existing (Old) Concrete: Surface should be clean and structurally sound. Remove all residues, curing compounds, oils, sealers, contaminants and laitance before applying LITHIUM. ULTRITE® DEGREASER from W. R. MEADOWS may be used for cleaning. (Refer to data sheet #353.) Fill and repair all holes, cracks and deteriorated areas that have been removed to sound concrete.
Application Method…Fresh Concrete: Apply undiluted LITHIUM at approximately 300 ft.²/gal. (4.91 m²/L) using a low-pressure sprayer or by spreading evenly with a soft-bristled broom. Do not allow material to puddle on the surface. No further application steps are required for fresh concrete.
WARNING: Immediately wash off over-spray from glass, aluminum, or highly polished surfaces with water to avoid etching of surfaces.
Burnishing … LITHIUM can be burnished to a high sheen on steel trowel concrete floors. A high-speed burnisher (2000-2200 rpm) with appropriate maintenance pad is needed.
Drying Time … 2 hours. LITHIUM dries very quickly on new, virgin concrete. Drying times may be extended on existing (old) concrete due to surface conditions. Restrict foot traffic for at least four hours;12 hours is preferable.
Cleanup … While still wet, equipment may be cleaned quickly and easily with soap and water.
DO NOT DILUTE. Do not apply if the temperature of the concrete is less than 35˚ F (2˚ C) or above 135˚ F (57˚ C). KEEP FROM FREEZING. If frozen, product should be thawed and agitated slightly prior to use.
LITHIUM is non-combustible. (Flash point is greater than 210˚ F.) Direct contact will result in irritation of the skin and eyes. Inhalation of product mist may result in respiratory irritation. Refer to Material Safety Data Sheet for complete health and safety information.
