You’re wondering about asphalt crack filler. Here are answers to your burning questions about KOLD-FLO® Gilsonite Modified Pourable Crack Filler, such as container size, temperatures, sanding, sealing and shelf life.

[dropdown_box_toggle_all hide=”Hide All Answers” show=”Show All Answers” separator=” | ” /]

What type of crack filler is KOLD-FLO® Gilsonite Modified Pourable Crack Filler?

[dropdown_box start=”hide” expand_text=”answer” show_more=”show”]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.[/dropdown_box]

Is mixing or heating required?

[dropdown_box start=”hide” expand_text=”answer” show_more=”show”]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.)[/dropdown_box]

What size containers is KOLD-FLO® available in?

[dropdown_box start=”hide” expand_text=”answer” show_more=”show”]Kold Flo® is packaged in 1-gallon bottles, 5-gallon pails and 55-gallon drums.[/dropdown_box]

What temperatures can KOLD-FLO® be applied?

[dropdown_box start=”hide” expand_text=”answer” show_more=”show”]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.[/dropdown_box]

Is KOLD-FLO® affected by freezing temperatures?

[dropdown_box start=”hide” expand_text=”answer” show_more=”show”]YES! Freezing temperatures will destroy KOLD-FLO® during storage or within 24 hours of application.[/dropdown_box]

What size cracks can be filed with KOLD-FLO®?

[dropdown_box start=”hide” expand_text=”answer” show_more=”show”]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.[/dropdown_box]

Does KOLD-FLO® need to be sanded after application?

[dropdown_box start=”hide” expand_text=”answer” show_more=”show”]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.[/dropdown_box]

Can KOLD-FLO® be seal coated over?

[dropdown_box start=”hide” expand_text=”answer” show_more=”show”]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.[/dropdown_box]

What is the shelf life of KOLD-FLO®?

[dropdown_box start=”hide” expand_text=”answer” show_more=”show”]KOLD-FLO® asphalt crack filler lasts 6 months minimum when stored properly.[/dropdown_box]
