KOLD-FLO® crack filler FAQs
Answers to frequently asked questions about KOLD-FLO® asphalt crack filler.
You’re wondering about asphalt crack filler. Here are answers to your burning questions about KOLD-FLO® crack filler container size, temperatures, sanding, sealing and shelf life.
What type of crack filler is Kold Flo®?
Kold Flo® is an asphalt emulsion based material modified with latex and fillers. Kold Flo® can be used on asphalt or concrete pavement as a asphalt crack filler material.
Is mixing or heating required?
NO! Kold Flo® asphalt crack filler is ready-to-use right from the container. (If settling occurs from prolonged storage, nominal mixing may be necessary.)
What size containers is Kold Flo® available in?
Kold Flo® is packaged in 1-gallon bottles, 5-gallon pails and 55-gallon drums.
What temperatures can Kold Flo® be applied?
Kold Flo® can be applied when the ambient temperature is above 50° F and below 90° F. It is best to fill cracks in early spring or late fall, when pavement cracks are at their widest points.
Is Kold Flo® affected by freezing temperatures?
YES! Freezing temperatures will destroy Kold Flo® during storage or within 24 hours of application.
What size cracks can be filed with Kold Flo®?
Kold Flo® is designed to penetrate into cracks ranging from 1/4″ to 1″ width and depth. The larger cracks may require a second application due to water evaporating during the curing process. Shrinkage of material in the crack may occur requiring a second application.
Does Kold Flo® need to be sanded after application?
NO! Kold Flo® will surface cure between 15 minutes to 1/2 hour after application, allowing for quick traffic access. Extreme humidity may prolong curing time. This asphalt crack filler takes at least 8 hours to completely cure. Insufficient curing time (during rain) may re-emulsify Kold Flo® causing it to “wash out” of the cracks.
Can Kold® Flo be seal coated over?
YES! We recommend crack filling with Kold Flo® and allowing it to cure for 24 hours before seal coating over. Smaller cracks filled with Kold Flo® may be sealed over earlier, once Kold Flo® has cured.
What is the shelf life of Kold Flo®?
Kold Flo® asphalt crack filler lasts 6 months minimum when stored properly.
