Instruction for use Surface Preparation: Concrete surfaces must be structurally sound, free of loose or deteriorated concrete and free of dust, dirt,
paint, efflorescence, oil and all other contaminants. Mechanically abrade the surface to achieve a
minimum surface profile of CSP 5 – 7 in accordance with ICRI Guideline 310.2. Properly clean profiled
area.
Priming: Clean and prime exposed steel with Ozone SBR. The Ozone SBR primer coating must be allowed to fully
dry prior to the placement of Ozone Patchcrete. Concrete should be primed with a spray or brush coat of
Ozone SBR. Alternately, a saturated surface dry (SSD) concrete surface can be primed with a scrub coat
of Ozone Patchcrete. The repair must be made before the scrub coat dries out.
Mixing: Single bags may be mixed with a drill and “jiffy” mixer. Use a paddle-type mortar mixer for large jobs.
O O All materials should be in the proper temperature range of 16 C to 32 C. Add the appropriate amount of
water for the batch size and then add the dry product. The mixed product should be quickly transported to
the repair area and placed immediately.
Placement: Place Ozone Patchcrete onto the prepared concrete or masonry surface while the bond coat is still wet.
Float or trowel flush with adjacent surface and allow to set. Finish to match the surrounding surfaces.
Curing: Follow ACI guidelines for curing. In the case of high temperatures, high wind, or low humidity causing rapid
surface drying, use a fog curing system or a water-based curing compound. Do not use solvent-based
curing compounds.
Cleaning & Disposal Ozone Patchcrete may be removed from tools and equipment with water before the dries. Don’t dispose
of into water or soil but according to local regulations.
Precautions/Limitations Only mix as much material that can be used within the pot life.
Do not add more water, re-temper or over-trowel.
