UNIQUE FLEXICRETE® XP Polymer Modified Mortar

• Use from featheredge to 2" deep.
• Excellent adhesion to concrete surfaces.
• Non-shrink/Volume stable.
• Abrasion resistant.
• Open to foot traffic in 4-6 hours.
• Open to vehicle traffic in 8-12 hours.
• Increased freeze-thaw durability and resistance to deicing salts.
• Compatible with the thermal expansion of concrete.

Use to repair roadways, industrial floors, loading docks, parking garages, curbs, utility cuts, pre-cast & sidewalks.

Not intended for applications on unsound concrete or like surfaces. Not recommended for applications over 2" deep. For deeper applications use UNIQUE FLEXICRETE® 25 Polymer Modified Concrete Mix or contact UNIQUE’s Technical Department. For overlay applications at least one test section should be prepared to evaluate the suitability of the materials and procedures.

Why has the concrete failed? Is there presence of salt, freezing damage, drainage water, deteriorated control or expansion joints? The surface area to be repaired should be in solid condition.

The area to be repaired should be checked with a chipping hammer to ensure the exposed concrete is not scaling. If a section of concrete is deemed to be questionable, complete removal and replacement should be considered. Patching over control or expansion joints is not recommended. The quality and durability of your repair depends on the surface to be patched. Remove loose concrete, mineral salts, grease and paint that will limit bonding performance. Mineral salt should be treated with an acid wash to ensure its removal. Exposed rebar should be free of rust or scaling then protected with a zinc oxide coating to reduce the probability of future rust development. Wet the repair area with water leaving it Saturated Surface Dry (SSD) during the repair. Any standing water should be removed.

For best results the water temperature should be between 55ºF and 75ºF.

• Warmer water will accelerate the set of the material.
• Cooler water will slow the set of the material.

Organize work so all personnel and equipment are in place before mixing. Roll or shake the sealed pail of UNIQUE FLEXICRETE XP polymer modified mortar to ensure the product is thoroughly mixed prior to use. Use clean, potable water. The use of a mortar mixer or variable speed drill is recommended. UNIQUE FLEXICRETE XP polymer modified mortar may be mixed using the percentages of water as shown in the table below:

Use less water to achieve higher strengths. Do not exceed the recommended water percentages.

Place the desired quantity of water into the mixing container. While the mixer is running add the material. Mix for the minimum amount of time required to achieve a lumpfree, uniform consistency (usually 1 to 3 minutes). Let material false set for 1 to 3 minutes to ensure the polymers have had time to hydrate. Re-blend material for 2 to 3 minutes to ensure a uniform consistency.

Make sure surface is SSD and any standing water has been removed. UNIQUE FLEXICRETE XP polymer mortar may be placed using traditional methods from featheredge to 2". Place and consolidate the material quickly to allow for maximum finishing time. UNIQUE FLEXICRETE XP polymer mortar may be troweled, floated or broom finished.

10 pounds of UNIQUE FLEXICRETE XP polymer modified mortar yields approximately 0.11 cubic foot of finished product when mixed with 28 ounces of potable water. Material will yield about 10 pounds per square foot per 1" thick.

Water soluble prior to drying. Clean container and tools prior to material drying.

Damp cure all installations. Begin curing as soon as the surface has lost its moist sheen. Keep exposed surfaces wet for a minimum of 1 hour. When experiencing extended setting times due to cold temperature or the use of retarder, longer cure times may be required. The objective of damp curing shall be to maintain the continuously wet surface until the product has achieved sufficient strength.

Warm environmental and materials temperatures will reduce the working time. To compensate for warm temperatures, keep material cool and use chilled water. Temperatures below 60ºF will decrease the rate of strength gain. UNIQUE FLEXICRETE XP polymer modified mortar should not be applied if surface temperature is below 45ºF or above 90ºF.
