FINAL RESULTS Floor is ready for traffic and use when dry. Typical drying time is 1-2
For an increased immediate shine, water repellency,
chemical and stain resistance, clean floor thoroughly, apply an additional light top-coat of L2-Top Coat – Dust Proofer -Hardener, Sealer and Densifier. Allow the L2-Top Coat to dry overnight and then burnish with a high speed propane buffer equipped with black pad, followed by a red pad. Burnishing with a black pad followed by a red pad will increase reflectivity on smooth surfaces more quickly. Second applications are WATER-BASED - V.O.C. COMPLIANT – HIGH SOLIDS rarely needed; however, if the concrete is very porous or if a quicker sheen is desired, apply a second application with the following procedure: Lightly mist the surface with PRODUCT DESCRIPTION

L2-Lithium™ (General application instructions) Review technical information and application guidelines for Decorative Polished Concrete (available on request) before using L2-Lithium. Example for Illustrative purposes: L2 Lithium may be applied immediately after all surface prep/grinding is completed, generally at the 100 to 120 Resin-Bond Diamond level. Continue with Resin-Bond Diamond passes (220-400; 600-800; 1800–3500) depending on the specified level of top-coat sheen [reference Chem-Coat Industries Polished Concrete Specification data for further information]. AVAILABILITY
Generally, the higher the resin-bond diamond level – the result will be a higher 1-Gallon Units, 5-Gallon Units, 55-Gallon Drum sheen/gloss finish. First, clean floor thoroughly to remove any dust from prep/grinding. SURFACE PREPARATION Do a smal test in an inconspicuous area
Second, apply L2-Lithium™ with a spray bottle or pump up sprayer, and then spread before project application to assure compatibility of al products. If you evenly with a micro fiber mop. Allow to dry then repeat if necessary. Do not allow the application of the L2-Lithium™ product to “pool” on floor.

Prior to applying the bond breaker, use the above procedure, then apply bond breaker as the curing agent on top of the L2-Lithium™ treatment.
L2-Lithium™ may be applied to existing, cured
concrete of any age (Minimum Cure is 28 Days) All surfaces must be clean and
sound. Mechanically remove any surface laitance and patch or fix cracks and
damaged areas. Completely remove all membrane forming curing compounds,
sealers, coatings, paint, oil, grease, dirt, dust and other containments. It is
recommended to thoroughly clean the surface with a black scrubbing pad (light
abrasion) and a neutral pH detergent. Etching of the surface with an acidic solution is
NOT recommended, because it requires a thorough rinsing process using a neutral
pH cleaner to effectively neutralize the entire surface (if not properly neutralized, the
pH condition may cause whiting). For best results, clean the surface by sanding the
floor with a 60-100 grit sanding screen or diamond abrasive pad. Remove dust and
residue with a riding or walk-behind “scrubber” utilizing water or broom, then water
rinse and squeegee surface dry. Use a low pressure or HVLP sprayer to apply L2-
