- Recommended Uses
Use to repair roadways, industrial floors, loading docks, parking garages, bridge decks, footings and sidewalks.
- Limitations
Not intended for applications on unsound concrete or like surfaces. Not intended for applications over 6" deep. For deeper applications use UNIQUE® Highway DOT Fast Setting Concrete Mix or contact UNIQUE’s Technical Department. For overlay applications at least one section should be prepared to evaluate the suitability of the materials and procedures.
- Surface Determination
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.
- Surface Preparation
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 the 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
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.
- Mixing
Organize work so that all personnel and equipment are in place before mixing. Roll or shake the sealed pail of UNIQUE HPFS mortar to ensure the product is thoroughly mixed prior to use. Use clean, potable, drinkable water. The use of a mortar mixer or variable speed drill is recommended. UNIQUE HPFS mortar may be mixed using the percentages of water as shown in the table below:
Water UNIQUE® High Performance
Fast Set Mortar20 - 22 oz. 10# 40 - 44 oz. 20# 3.3 - 3.4 qt. 50# 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 UNIQUE HPFS mortar. Mix for the minimum amount of time required to achieve a lump-free, uniform consistency (usually 1 to 3 minutes). Do not re-temper. Do not mix more material than can be placed in a 10 minute period.
If mixing smaller amounts of UNIQUE HPFS mortar, thoroughly mix the entire pail of dry ingredients prior to adding the product to the water.
- Placement
Make sure surface is SSD and any standing water has been removed. Place, consolidate, screed and apply finish as soon as possible (Do not wait for bleed water). Trowel mixed material into the voids of the existing concrete. Place product in full depth sections. Product may be trowel floated or texture finished. Do not layer material. Do not apply on frozen surfaces.
- Extending
Option to extend up to 50% using clean pre-dampened 3/8" (ASTM-C33) aggregate.

Water soluble prior to drying. Clean container and tools prior to material drying.
- Curing
Damp cure all UNIQUE HPFS mortar 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.
- Temperature
Warm environmental and materials temperatures will reduce the working time of UNIQUE HPFS mortar. To compensate for warm temperatures, keep material cool and use chilled water. Temperatures below 60ºF will decrease the rate of strength gain. UNIQUE HPFS mortar should not be applied if surface temperature is below 45ºF or above 90ºF.
