~, <br />~~ <br />Surface Preparation <br />Proper surface preparation is important (or the long term <br />performance of this system. For detailed information on surface <br />preparation and application, please refer to ARC Application <br />Manual for Concrete. Generally new concrete must be cured for <br />a minimum of 26 days. <br />Remove all grease, oils, and grime by warning with an <br />emulsifying alkaline waterbase cleaner. All surface contaminants <br />including old coatings, chemical salts, dust, loose concrete, and <br />the laltence layer must be removed. This Is best accomplished by <br />hydro-blasting, steel shot-blasting, scarifying, or tlry abrasive <br />blasting The resulting surface must be structurally sound and <br />free of all contaminants. Surface dampness is acceptable, <br />standing water is not. For slab on grade applications, a vapor <br />barrier is recommended. II no vapor barrier is present, check for <br />vapor transmission <br />Mixing <br />To facilitate mixing and application, material temperatures should <br />be between 21 °C - 32'C (70°F - 90°F). Each kit is packaged to <br />the proper mix ratio. If further proportioning is required, the kit <br />should be divided to the coned mix ratio. <br />Mix Rafio By Weiahf Volume <br />A:B 3.1:1 3.0:1 <br />Prior to mixing ARC CS2, pre-mix Part A to suspend any settled <br />reinforcements. When applying by hand, add Part B to Part A. <br />Mix by hand for 1 minute. Shih a Small portion o(this mix back to <br />the Part B container and scrape the walls of this container to <br />remove all Iraces of residue. Add Ihis portion back to the Pan A <br />container. Continue to mix product until product is uniform in <br />color and consistency, no streaks. Power mixing should be <br />accomplishetl with a variable speed, high torque, low speed mixer <br />with anon-air entraining mix blade such as a "Jiffy" blade.

Build successive <br />passes to achieve final first coat desired thickness. Vertical or <br />overhead applications will result in reduced film thickness. To <br />compensate additional coats are recommended. Use the chart <br />below to determine the desired final film Ihlckness recommended <br />for the application. <br />Multiple coat applications of ARC CS2 may be accomplished, <br />without additional surface preparation, as Iring as the film is free <br />of contamination and has not cured beyond the stage stated as <br />Light Load in the Curing Schedule chart be ow.

All <br />clean up activities must be carried out as soon as possible to <br />prevent material hardening onto the tools Use commercial <br />solvents (Acetone, Xylene, Alcohol, Methyl f_thyl Ketone) to clean <br />tools immediately after use. Once cured the material would have <br />to be abradetl off. <br />Storage <br />Store between 10'C (50°F) and 32°C (90°F). Excursions beyond <br />this range which may occur during shipping are acceptable. The <br />shelf life is two years in unopened container:;, Settling and <br />reintorcemenf separation may occur over tinge oral elevated <br />storage temperatures. Reconstitute prior to use by mixing <br />individual components before mining Part A •Mith Part B. <br />Safety <br />Before using any product, review the appropriate Material Solely <br />Data Sheet (MSDS) or Safety Sheet for your area.
