Product Details

This professional grade crack filler is compatible with oil jacketed asphalt kettles and direct fire crack filler equipment such as the Hotbox 10 and Hotbox 30.A most economical and best selling crack fill machine to melt down and apply this crack filler is the 10 gallon direct fire crack machine the Hotbox 10. As long as the crack filler is not heated for an extended amount of time above its flash point (when bubbles start to form) the asphalt repair result should be a permanent one that last for up to 10 years.



How much crack filler do I need?

Generally speaking, a standard driveway uses about 6 blocks. A long driveway or a small parking lot uses about 12 blocks. If you are still unsure how much you need for your crack fill project, use our crack fill calculator here to calculate how many LBS of crack filler you need.


Hot crack filler is traffic ready as soon as it cools down enough to become not tacky anymore, which takes 10-40 minutes depending on the weather. In cold weathers the melted crack filler cools faster. To test, you can use a stick to poke the filler sealant, if it does not tack to the stick then you are ready for foot traffic. Give it an additional few minutes for vehicle traffic.



Can I fill driveway cracks in the winter?

It depends on where you are, it is recommended to fill cracks when pavement is at least 40°F. That being said it is still possible to fill cracks in cold weathers by heating up the pavement by using a heat lance or a weed torch. Torching the cracks prior to crack filling also makes sure the crack walls are completely void of moisture.


What temperature should I apply hot pour crack filler at?

380 - 400°F (193 - 204°C). Try to keep the crackfill machine's temperature under 500°F as prolonged exposure to high heat will oxidize and age the asphalt in the crack filler.


Does hot crack filler expire? 
How long can I keep unused crack filler?

Generally speaking, unlike cold crack filler which is emulsified with water, hot crack filler does not "expire". Most hot asphalt crack filler has a shelf life of 10 years or more. If stored outside, make sure to keep unboxed sealants out of direct sunlight as UV damage is one major factor that ages the sealant. In addition prolonged high temperature can accelerate asphalt aging so when the weather gets hot it may be a good idea to bring the crack filler in doors or to a cool shady place. 


Can you seal coat over the filled cracks?

Yes. Both hot rubber asphalt crack filler and cold pour crack filler cracks can be sealed over with a driveway sealer. All are asphalt based products.


After crack filling, how soon can you seal coat?

For both liquid cold-pour crack filler, it is important to let the sealant dry completely before spraying or squeegeeing on seal coat, as trapped water will affect bonding later. It takes cold crack filler 24 to 48 hours to completely dry.

For hot pour crack filler, as there is no water in the formula it is ready for seal coat application much sooner, usually in 20-40 minutes. It is important to let the hot crack filler cool down to ambient temperature prior to applying driveway sealer. 


When melting the hot tar crack filler, does the plastic wrapper go inside the melter kettle?

Yes. The plastic wrapper is designed to melt together with the hot crack filler inside the kettle.


Does the hot pour crack filler work with latex paint?

Use with caution. The rubber asphalt will bond to the paint. However the paint might peel off the pavement overtime. 


How many blocks can a 10 gallon melter take?

Each block of hot asphalt crack filler melts down to about 2.5 gallons. So 3 to 4 blocks can go in the 10 gallon crack filling machine melted, or 6-12 blocks in the 30 gallon crack melter kettle.


Each pound of hot crack filler covers about 7-8 linear feet of medium width cracks. Each crack filler block covers about 150 linear feet of medium cracks, or 200 linear feet of small cracks. It is recommended that for large and deep pavement cracks, fill the crack with silica sand till about half inch to the pavement surface prior to pouring crack filler product. This gives better structural support as well as using the crack filler more efficiently.
