Asphalt Sealcoating Direct sells a large quantity of Asphalt Repair items including Hot Pour Crack Fill. This product is extremely pliable and is Direct Fire crack fill material.

Flex-A-Fill is a high-quality Hot Asphalt Crack Filler material that is available in a convenient 30LB box (75 boxes Per Pallet) equaling 227 gallons of material that easily fits into direct fire kettles as shown in the video and pictures.

This Hot Pour Direct Fire Crackfill works perfectly with our popular Asphalt Crack Melter / Applicator and if you own and operate an asphalt repair business, then you probably own and operate crack filling melters and applicators too.

Specifically designed to withstand the higher temperatures of a direct fire kettle, this rubberized crack fill becomes very flexible after it has cooled, making it a perfect solution for parking lots or professional driveway repair.

Direct Fire Crackfill Rubber is specifically designed for use with Direct Fire Melting Kettles using a thermometer to monitor melting temperature up to 400 degrees and usually has a higher flash point than its counterpart which is designed for use with Oil Jacketed melting kettles.

Hot Pour Crack Fill is designed to seal cracks or joints in asphalt or concrete surfaces, which are up to 1" in width and up to 1/2" in depth.

This material must be applied to cracks that are free from all foreign matter and debris. We suggest the use of a heat lance or wire wheel prior to filling asphalt cracks.

This material can be poured directly from the melter or pour pot into the crack and should yield approximately a rate of 100 linear feet per 12.5 pounds of crack filler as long as the crack your filling is not more than 1” wide and filler such as sand or hot mix is used to fill the crack to ½" below the cracks surface.

It is advisable to use an applicator melter that has a thermometer as the maximum recommended temperature of the sealer is 400 degrees.

This Hot Pour Crackfiller can be used in a direct bottom fired melter, or a double boiler type melter

  • Application: Apply to clean dry cracks when ambient and pavement temperatures are above freezing. Joints and cracks should be filled full and tight squeegeeing may be desirable.

Our asphalt crack repair rubber is designed for cracks in parking lots and driveways that are around 1" width by 1/2" depth. If you are filling cracks deeper than 1/2", we recommend filling the crack with some sort of backer such as sand or foam. This is a harder rubber that does become flexible when cured, but is stiffer than a street rubber to reduce tracking and tire marks.


Before you perform asphalt crack repair with this material, the cracks must be free from all foreign matter and debris. We suggest the use of a heat lance or wire wheel prior to filling asphalt cracks.


Simply add a block of rubber to your direct fire or double oil jacketed boiler applicator melter of choice. Make sure that the internal heat does not exceed the maximum recommended temperature of 400º F. Apply generously to the cracks needing repair.

If a half pallet is more than you need, we also offer single box quantities for purchase.
