Uses :
Concrete repair mortar designed to repair heavy duty surfaces such as:

• Highway repairs and overlays
• Bridge decks and parking structures
• Airport runways
• Freezer rooms
• Heavy industrial and warehouse repairs
• Loading docks and wastewater treatment facilities

Installation:

Preparation: All materials should be stored at 40°F (4°C) to 80°F (27°C) 24 hours prior to installation. Surfaces must be solid, clean, free of all bond breakers such as oil, grease, dirt etc. Weak concrete surfaces must be cleaned down to solid sound concrete by mechanical means.

• The base concrete should be roughened to enhance mechanical bond and repair areas should be in a saturated surface dry (SSD) condition with all standing water removed. Using a stiff broom or brush apply a bond scrub coat of thinly mixed Premium Patch 100 to the adjacent surfaces.
• Do not let this bond coat dry, before covering it with Premium Patch 100. A minimum patch repair depth of 1/2” (13 mm) is required. This is best accomplished by saw cutting the patch area perimeter to the minimum 1/2” (13 mm) depth.
• Note: It is the responsibility of the installer/applicator to ensure the suitability of the product for its intended use.

Application: Ideal application conditions are when air, material and substrate temperature are between 40°F (4°C) and 80°F (27°C). For applications outside this range of temperatures, contact ProSpec® Technical Services.

Hot and Cold Weather Applications: Ideal mixed product temperature at placement is 65o - 70oF (18o - 21oC), where the initial setting time is 20 - 30 minutes. Hot temperatures will shorten setting time, while cold temperatures will extend setting time.

Hot Weather °F to 100°F (27°C to 38°C): Keep Premium Patch 100 cool. Pre-soak and then remove standing water from the repair area, resulting in a saturated surface dry (SSD) surface. Mix Premium Patch 100 using ice water to extend working time. The repair must be protected from rapid dry out with wet burlap or a water-based curing compound.

Cold Weather 20°F to 40°F (-7°C to 4°C): Do not use antifreeze or accelerators and keep Premium Patch 100 warm. Heat the surrounding concrete until warm. Combine the warmed repair material with warm mixing water. After placing use a construction insulating blanket for at least 2 - 3 hours and keep material from freezing.

Job Mockups: The manufacturer requires that when its ProSpec® products are used in any application or as part of any system that includes other manufacturers’ products, the contractor and/or design professional shall test all the system components collectively for compatibility, performance and long-term intended use in accordance with pertinent and accepted industry standards prior to any construction. Written documentation of the tests performed shall be satisfactory to the design professional and contractor. Test results must include the means and methods of application, products used, project-specific conditions being addressed, and standardized tests performed for each proposed system or variation.

Mixing:

• Mix as close to the area being repaired as possible. Premium Patch 100 requires only the addition of water. Use 2.5 qt (2.4 L) per 50 lb (22.7 kg). Place the potable water into the mixing container and then while mixing add the repair material.
• The Premium Patch 100 can be mixed in a mortar mixer or by using a paddle attached to a heavy duty 1/2” drill (650 rpm). Mix for 2 - 3 minutes to a lump free consistency. Do not re- temper or overwater.
• Place immediately after mixing, working Premium Patch 100 firmly into the sides and bottom eliminating air pockets and ensuring bond. This is best done working from one side of the cavity to the other and then screeding toward the adjoining concrete.
• For repairs deeper than 2” (5 cm), Premium Patch 100 can be extended 60% by weight using clean 3/8” (10 mm) dry pea gravel. Mix the Premium Patch 100 as outlined and then during the last minute of mixing (after 2 minutes) add the pea gravel, blend for 1 additional minute and place.

Curing: Premium Patch 100 should be moist cured for 1 hour after final set (approximately 20 minutes) or the application of a water- based curing compound is acceptable. Prolonged wet curing minimizes the chances of cracking and improves physical properties.

Cleaning:
Use water to clean all tools immediately after use.
Limitations:

• Do not use for applications less than 1/2” (13 mm) thick.
• Do not retemper after mixing.
• Do not overwater or add other cements or additives.
• Protect from premature drying.

Coverage:

• 50 lb (22.7 kg) yields approximately 0.4 ft³ (0.01 m³).
• 50 lb (22.7 kg) extended with 30 lb (13.6 kg) of 3/8” (10 mm) pea gravel yields approximately 0.7 ft³ (0.02 m³).

12 months from the date of manufacture when stored in the original, unopened container, away from moisture, under cool, dry conditions and out of direct sunlight.
