Roklin Systems Inc. Flomix Rapid Asphalt Repair 3 Gallon Kit FloMix is a cold-applied, liquid and aggregate slurry that hardens in minutes to provide a long-lasting repair, without the need for removal of damaged asphalt or dig-outs of any kind. FloMix utilizes our patented, coated aggregate, which contributes to flowability and ease of installation on potholes, alligatoring and cracks. FloMix asphalt patch repair can be finished precisely to grade, resulting in a smoother ride over the repaired areas like driveways, runways and sidewalks. FloMix is easily feathered into the surrounding asphalt to form a repair that blends in visually with the existing pavement. In temperatures below 58, add 1-ounce bottle of catalyst to your order. This will cause FloMix to set up faster in cold weather. Catalyst is not included.
