Features and Benefits

  • Can be featheredged
  • Lifts up to 1” in thickness
  • 5 minute set time for quick turn around
  • Can be shaped
  • Excellent durability and adhesion
  • Dries to color of concrete

 


Application

  • Interior & exterior
  • Vertical, overhead & horizontal repairs
  • Used at no slump consistency
  • Outstanding repair material for concrete pipe, curbs, sidewalks, formed and precast concrete
  • Surface Preparation: The concrete must be sound and free of all foreign material, including oil, grease, dust, laitance or other surface contaminants. Saw cut the perimeter of the repair to a maximum depth of ½”. Mechanically abrade the surface by an engineered approved method, such as grinding, abrasive blasting, or scarifying. All surfaces to be repaired should be in a saturatedsurface-dry (SSD) condition with no standing water on the surface.SpecPatch 5 takes its initial set in 5 minutes.

    Mixing: Mix 6.75 – 7.25 pints (depending on desired consistency) of clean water per 50 pound bag of material. Mix with a low speed drill. Add recommended amount of clean water into the container, followed by the SpecPatch 5. Mix 2 to 3 minutes. Mix only what can be applied within the setting period. SpecPatch 5 may be used with SpecChem Acrylic Bonder neat or mixed 1 to 1 with water per 50 pounds of powder to increase durability, abrasion resistance and bond strength. The addition of Acrylic Bonder is recommended when using SpecPatch 5 in thin, horizontal applications subjected to heavy traffic or wear.

    Bond/Scrub Coat: Use the properly mixed SpecPatch 5 as a bond or scrub coat by scrubbing a thin layer into the pre-dampened substrate with a stiff brush. Place the SpecPatch 5 mortar immediately before the bond coat dries.

Placement: Trowel SpecPatch 5 firmly into the prepared area, ensuring intimate contact with the bonding surface. Use slightly more material than is needed and roughly shape during placement. After the initial set, when SpecPatch 5 is surface hard, shave the material to the desired final shape using a steel trowel. Maximum depth of neat repair mortar is 1” for each lift. Additional lifts can be placed after the original lift has achieved set. The original lift should be left with a rough surface to improve
bond between lifts.

Finishing/Curing: Finish the repair material to the desired texture to match the surrounding concrete. SpecPatch 5 is self-curing under most conditions. In severe drying conditions, use an ASTM C-309 compliant, water based SpecChem curing compound.

Coverage: approx 20 sq-ft @ 1/4”
