    How To Apply
    Surface Preparation
    Remove all loose material including dust, oil and grease. Minimum application depth should be 3/4". Repair edges should be cut to depth to avoid feather-edging. Dampen bare concrete with clean, cold water. Remove any standing water. Briefly warm the area using a blowlamp or gas torch. This helps to accelerate curing.

    Warning Do not mix the product for more than 4 minutes. Use immediately. Watco Flowpatch Sub Zero cures very quickly and the mixed product must be applied and finished within 10 minutes.

    Mixing must be carried out in an ambient temperature above 41ºF. If mixing at temperatures below 41ºF, pre-warm the mixing vessel with warm (approximately 77- 86ºF) water. Remove the bag of powder and pour 1/2 gallon of clean, cold water into the plastic container. Gradually add all the powder, mixing thoroughly. Continue mixing to produce a smooth workable mortar.

    Trowel Watco Flowpatch Sub Zero firmly into place using a steel trowel or float (available from Watco). The trowel can be wiped with clean, cold water to make finishing easier. Apply the product at a minimum 3/4" thickness, if using at a temperature range of -4ºF to 41ºF.
