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. 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 saturated-surface-dry (SSD) condition with no standing water on the surface.

Precast Patch takes its initial set in 15 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 Precast Patch. Mix 2 to 3 minutes. Mix only what can be applied within the setting period. Precast Patch 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 Precast Patch in thin, horizontal applications subjected to heavy traffic or wear.

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

Placement: Trowel Precast Patch 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 Precast Patch 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. Precast Patch is self-curing under most conditions. In severe drying conditions, use an ASTM C-309 compliant, water based SpecChem curing compound.
