PLACEMENT GUIDELINES

1. SURFACE PREPARATION: All surfaces in contact with Tasir® Easy-Cure Repair Mortar V/O shall be free of oil, grease, laitance, and other contaminants. Concrete must be clean, sound and rough to ensure a good bond. Mechanically roughen concrete surfaces in accordance with ICRI Technical Guideline 03732 to a minimum concrete surface profile roughness (CSP) 6 or greater. Remove all oxidation from exposed reinforcing steel. A perimeter edge and minimum depth of 1/4 inch (6 mm) should be provided for a durable repair. Featheredging is not recommended. Soak concrete surfaces prior to application with liberal quantities of potable water leaving the concrete saturated and free of standing water. Surfaces shall be conditioned to between 45°F and 90°F (7°C and 32°C) at the time of placement.

2. MIXING: Step 1—Mix Tasir® Easy-Cure  Repair Mortar: Pre-wet mortar mixer (stationary barrel mixer with moving paddles); empty excess water. A drill and paddle mixer is acceptable for single bag mixes. With the mixer running, add 3 to 3¼ quarts potable water (maximum per 50 lb. bag) to the mixer followed by Tasir® Easy-Cure  Repair Mortar and mix for 2-3 minutes. Step  2—Add  Tasir®  Easy-Cure Repair Mortar V/O Additive: Continue mixing and add Tasir® Easy-Cure Repair Mortar V/O Additive to the mixer. Mix for an additional 2 minutes. Use material immediately after mixing is completed. Do not mix more material than can be placed within 10 minutes at 70°F (21°C). Mixing Less Than Full Units: For detailed mixing and placement procedures, call the Five Star Products’ Engineering and Technical Service Center at +86-571-87569602.

3. METHODS OF PLACEMENT: Firmly work a thin amount of repair material as a bond coat into damp concrete surface. Immediately apply additional material with trowel taking care not to leave air pockets. Application is from one side of the repair to the other, filling the repair to the desired level. Where multiple lifts are required for deep repairs, rake or scratch surface of initial lift and allow to harden for approximately 45 minutes (70°F/21°C) before applying next lift. Contact the Five Star Products’ Engineering and Technical Service Center at 1-800-243-2206 for additional details on multiple lift applications. Finish as necessary. Tasir® Easy-Cure Repair Mortar V/O requires no wet cure or curing compounds.

SPECIAL CONDITIONS: For use in cold temperatures,Tasir® Easy-Cure Repair Mortar V/O must be maintained at a temperature of at least 45°F (7°C). Protect from freezing until a compressive strength of at least 1,000 psi (6.9 MPa) is obtained. Faster strength gain will occur when the Tasir®  Easy-Cure Repair Mortar V/O and mixing water have been conditioned to a higher temperature prior to placement. In hot temperatures,Tasir®  Easy-Cure Repair Mortar V/O should be kept as cool as possible, but not exceeding 90°F (32°C). Chilled water should be used for mixing to help maintain sufficient working time.

4. POST-PLACEMENT PROCEDURES: Tasir® Easy-Cure Repair Mortar shall be protected from rapid drying, rain or excessive wind until initial set.

NOTE: PRIOR TO APPLICATION, READ ALL PRODUCT PACKAGING THOROUGHLY. For more detailed placement procedures, refer to Tasir installation guidelines or call the Tasir  Products'Engineering and Technical Service Center at +86-571-87569602.


CONSIDERATIONS

● Never exceed the maximum recommended amount of mixing water stated on the package or an amount that will cause segregation.

● Temperature of surfaces must be between 45°F and 90°F (7°C and 32°C) at time of placement.

● Repair material shall be protected from freezing until it reaches 1,000 psi (6.9 MPa).
