Dr.S Bond liquid floor hardner concrete densifier and chemical hardener compound is a proprietary, water-based, ready-to-use, clear silicate liquid, formulated with chemically reactive raw materials to harden and dustproof concrete. This waterborne solution, when properly applied, offers substantial improvement in abrasion and chemical resistance and will significantly improve the durability of the concrete surface when compared to untreated concrete. As liquid floor hardner 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, liquid floor hardner also solidifies the concrete, eliminating dusting and pitting.
Dr.S Bond liquid floor hardner 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. Liquid floor hardner can successfully be used in conjunction with shake-on hardeners.
Penetrates deeply into concrete to densify and harden surfaces to help prevent entry of moisture and other foreign matter.
Dustproofs and improves chemical, petroleum, and abrasion resistance of treated surfaces.
Provides a permanent, attractive sheen with the ability to polish.
Protects against scratching or peeling.
Provides tough, protected surface that won't after-yellow, discolor, or show pedestrian or vehicular traffic wear marks.
Improves light reflectance.
Ready to use from container and easy to apply.

*when used as a curing aid on newly placed concrete
Note : coverage rate may vary, depending on the finish and porosity of the concrete
When stored indoors in original, unopened containers at temperatures between 40° – 90° F (4° – 32° C), optimum performance and best use is obtained within one year of date of manufacture.
Surface Preparation … Fresh Concrete: On newly placed concrete, Dr.S Bond liquid floor hardner can be applied 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 Dr.S Bond liquid floor hardner.
Mixing … For optimum performance, gentle mixing or agitation is recommended.
… Fresh Concrete: Apply undiluted Dr.S.Bond liquid floor hardner at approximately 300 ft.2/gal. (7.36 m2/L) using a low-pressure sprayer, such as a spray nozzle, 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.
Saturate the surface with undiluted liquid floor hardner by sprayer, squeegee or broom. Keep the surface wet with liquid floor hardner for a minimum of 30 minutes. (A range of 30 – 60 minutes may be required depending on temperature and conditions.)
Pay particular attention to porous and/or dry areas. These areas must be kept wet at all times with liquid floor hardner. Once the surface begins to gel and becomes slippery, immediately spray the surface with a light water mist. Scrub the surface with a broom or mechanical scrubber to increase the penetration of the liquid floor hardner. Continue to work the liquid floor hardner into the surface for another 5 – 10 minutes or until liquid floor hardner becomes gelled and slippery for a second time. At this time, THOROUGHLY flush the surface with water. During the flushing process, agitate the surface with a broom to aid in removal of the excess liquid floor hardner. Remove all excess material with a mop or squeegee. Thoroughly squeegee the surface dry. If there are slippery patches, this is an indication that there is still excess liquid floor hardner present. These areas should be re-flushed and squeegeed again until the entire surface is dry. (Extremely porous surfaces may require a second application.)
Failure to thoroughly wash and remove all excess material from floor surfaces may result in unsightly white stains. Immediately wash off over-spray from glass, aluminum, or highly polished surfaces with water to avoid etching of surfaces
… 2 – 4 hours. Liquid floor hardner 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.
… While still wet, equipment may be cleaned quickly and easily with soap and water. Do not allow liquid floor hardner to dry before flushing excess from surfaces
Liquid floor hardner is non-combustible. Direct contact will result in irritation of the skin and eyes. Inhalation of product mist may result in respiratory irritation.
