Description

The Polyaspartic 745 is a solvent-based, two-component, aliphatic polyaspartic coating designed to coat concrete floors or concrete countertops providing incredible abrasion resistance and chemical resistance. Recommended for indoor areas with high risk of exposure to chemical spills, fuel, heavy equipment, extreme temperatures and any other potentially damaging situation the substrate may encounter. Polyaspartic 745 has an exceptionally fast dry-time, with a tack-free dry-time of a 3-7 hours which makes it the best choice for projects where a thin build coating is desired with a limited period of time for installation. Great for use on concrete countertops and concrete feather finish countertops where an extremely durable coating is needed.

  • Preparation

    Surface Prep

    1. The concrete substrate to be coated must be clean, dry, and completely free of loose particles, grease, oil, or any substance that would interfere with proper bond.
    2. Surface and air temperatures must be at least 55°F during application. Surface and air temperatures should not exceed 90°F. Keep material from freezing.
    3. The surface-zone moisture content of the concrete should not exceed 4% wt. A test should be made to determine that the concrete has an appropriate vapor barrier. This can be done by placing a 4’X4’ plastic sheet on the substrate and taping down the edges. If after 24 hours, the substrate is still dry below the plastic sheet, then the substrate does not show signs of eventual hydrostatic pressure problems that may later cause disbanding. Testing should be performed to confirm a moisture vapor emission rate below 3 lb/ 24hr/1000 ft2 per ASTM F1869.
    4. For a one or two coat thin build system (3-10 mils dry) we recommend either mechanical scarification or acid etching until a suitable profile is achieved. For a complete system build higher than 10 mils dry, we recommend a fine brush blast (shot blast). If acid is used to clean the concrete, neutralize the surface completely and rinse it with water prior to application. Then wait for the concrete to dry out for at least 24-48 hours.
  • Application

    Mixing: This product has a mix ratio of 1.5 gallons part A to 1 gallon part B. Standard packages are in pre-measured kits and should be mixed as supplied in the kit. After the two parts are combined, mix well with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak free. After mixing, transfer the mixed material to another pail (the transfer pail) and again remix. The material in the transfer pail is now ready to be applied on the primed substrate.

    Application: The mixed material can be applied by brush, serrated squeegee, or roller. Maintain temperatures and relative humidity within the recommended ranges during the application and curing process. The product can be used as a topcoat to seal in the broadcasted paint chip or broadcasted quartz base for the final coat. Use an air release roller tool when needed. Improper mixing may result in product failure. It should be pointed out that relative humidity can have a dramatic influence on the curing characteristics. The product will dry quicker and have less working time when the relative humidity is higher while a lower relative humidity will lengthen the dry time and working time. Mix only an amount that can be applied in the time allotted. Be sure that any tie-ins to previously applied material is also within the recommended time allotted for use as the previously applied material may begin to tack off in a short period of time.

    Recoating/Topcoating: This material can be applied in multiple layers to increase build or can also be used as the final topcoat to seal in the aggregate filled base system. If you opt to recoat or topcoat this product, you must first be sure that the coating has tacked off before recoating. Always remember that colder temperatures will require more cure time for the product before recoating or topcoating can commence.

    Application Notes:

    • Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured. It is best to let the floor remain dry for the full cure cycle. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.
    • Some cleaners may affect the color of the floor installed. Test each cleaner in a small area, utilizing your cleaning technique. If no ill effects are noted, you can continue to clean with the product and process tested.
    • Colors or clarity for clear may be affected by high humidity, low temperatures, or chemical exposure.
    • For best results use a high quality nap roller.
    • Slab on grade requires moisture barrier.
    • Substrate temperature must be 5°F above dew point.
    • Relative humidity must be below 75°F.
    • All new concrete must be cured for at least 28 days.
    • Improper mixing or too thick of an application may result in product failure.
    • Do not expose this product to water until fully cured.
    • Too thick of an application may result in surface imperfections or bubble generation.
