MIXING AND APPLICATION INSTRUCTIONS

PRODUCT STORAGE: Store product in an area so as to bring the material to normal room temperature before using. Continuous storage should be between 60 and 90 degree F. Keep from freezing.

SURFACE PREPARATION: Surface preparation will vary according to the type of complete system to be applied.  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)  All dirt, oil, dust, foreign contaminants and laitance must be removed to assure a trouble free bond to the substrate.  A test should be made to determine that the concrete is dry; 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 is dry enough to start coating.  The plastic sheet testing is also a good method to determine if any hydrostatic pressure problems exist that may later cause disbonding.

PRODUCT MIXING: This product has a two to one mix ratio by volume- merely mix two gallons of part A with 1 gallon part B.  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.  Avoid whipping air into the coating. Improper mixing may result in product failure. For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer.

PRODUCT APPLICATION: The mixed material can be applied by brush or roller.  Maintain temperatures within the recommended ranges during the application and curing process.  Properly prime the substrate.  It is best to maintain a wet edge to avoid roller marks.  Direct sunlight or high temperatures may cause visible roller marking during application.  Too thick of an application may result in product failure.  Exposure to certain types of lighting such as sodium vapor lights may cause the product to discolor. Applications with relative humidity higher than 90% and/or poor air circulation may cause improper cure and surface tackiness.

RECOAT OR TOPCOATING: Multiple coats of this product are acceptable.  If you opt to recoat this product, you must first be sure that all of the solvents have evaporated from the coating during the curing process.  The information on the front side are reliable guidelines to follow.  However, it is best to test the coating before recoating or topcoating.  This can be done by pressing on the coating with your thumb to verify that no fingerprint impression is left.  If no impression is created, then the recoat can be started.  Always remember that colder temperatures will require more cure time for the product before recoating can commence.  Before recoating or topcoating, check the coating to insure no contaminants exist.  If a blush or contaminants are present on a previous coat, remove with a standard detergent cleaner.  When recoating this product with subsequent coats of the urethane, it is advisable to apply the recoat before 24 hours passes.  Also, it is advisable to degloss the previous coat to insure a trouble free bond.

CLEANUP: Use ketone solvents

SURFACE CLEANING: Caution! 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.

RESTRICTIONS: Restrict the use of the surface to light duty and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the surface 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.

LIMITATIONS

• Colors or clarity for clear may be affected by high humidity, low temperatures, or chemical exposure.
• For best results use a high quality 3/8” nap roller.
• Slab on grade requires moisture barrier.
• Substrate temperature must be 5°F above dew point.
• All new concrete must be cured for at least 30 days.
• Light or bright colors (white, safety yellow, etc.) may require multiple coats or a suitable color coordinated primer to achieve a satisfactory hide.
• Colors may vary from batch to batch, therefore, use only product from the same batch for an entire job.
• Tire contact may cause discoloration or staining.
• Physical properties are typical values and not specifications.
