USES
CEM120H Full-depth repairs on grade and below-grade concrete. Minimum thickness of 1 inch to a maximum thickness of 8 inches (thicker applications can be achieved through applying in lifts) structural repairs for horizontal and form and pour repairs. Excellent for balcony, parking lot, parking deck, pedestals, curbs, equipment bases, re-sloping floors and industrial plant repairs. CEM20H can be used in
- Airport runways & taxiways
- Warehouse Floors
- Hangars Floors
- Highway Repairs
- Loading Bays
- Factory Floors
APPLICATION DATA
Water requirement: 1 Gallon (3.785 Liters) water is required for the 65 Lb. (29.48 Kg) Bag of CEM120H. Accurate measurement of water is very essential.
Coverage: 65 pounds will equal approximately 0.45 cubic feet.
Surface Preparation: All surfaces must be clean and free of dirt, dust, paint, sealers, coatings, loose material, adhesives, curing compounds or any material that will inhibit patching material from coming in contact with the concrete pores. Removal of any anti adherents or loose materials must be
accomplished mechanically.
Steel Reinforcement: Mechanically clean all surfaces to remove rust and corrosion (repair rebar as needed). Ensure enough concrete is removed to produce a 1-inch minimum repair.
Priming: In addition to a saturated, surface dry (SSD) substrate, the use of an epoxy or latex primer should be considered.
Mixing: Place 1 gallon of water into mixing container, followed by one 65lb. bag of CEM120H. Mechanically mix water and material to uniform consistency. Adjust water as needed up to 1.25Gal. CHEM-CRETE EB550 may be used in lieu of water for a more durable bond. Material may be pumped, poured into forms or used with wet or dry shotcrete method.
Application: In cold weather use warm (not hot) water for mixing. Dampen the surface of the work area before applying the new material. For a rough or non-slip surface, use a wooden float or broom. For a smooth finish, use a steel trowel. Avoid over troweling. Hot weather: (above 80 degrees) will cause faster setting; mix with cold water or ice to slow setting time.
Curing: For proper curing, keep moist for 3 days with an occasional fine spraying with water or cover with wet burlap or plastic. The use of a curing compound conforming to ASTM C-309 will also work; however curing compounds will need to be mechanically removed prior to coating. (Check with the coating manufacturer)
Cure patch with damp curing, especially in warm weather, in direct sunlight, and on thin sections.
Cleaning: Clean all mixing and application equipment with water immediately following use. Remove all splatter of spills with water before material sets.
STORAGE
Store CEM120H in cool dry storage facilities. Do not expose to direct sunlight. The shelf life of CEM120H is minimum 1 year if stored in a cool dry place in its original unopened container.
