Hot Rubber Crack Filling Products, Application Tools and Benefits

Posted by Terry Keenan in crack filler, hot rubber crackfiller
Pure Hot Pour Hot Rubber Crack FillerHot rubber crack filler is generally a commercial product commonly used on roadways and parking lots (there are residential cold rubber crack filler options for driveways). It is designed to seal cracks greater than 3/8" to prevent water from destroying the stone base beneath the pavement. The flexible rubber adheres to the edges of the crack and allows for the expanding and contracting of the ground with climate changes.

30 Gallon Hot Rubber Melter KettleThe process requires a heating machine, or melter kettle, that uses propane and requires some set up time, additionally you will want a v shaped squeegee to apply the product efficiently and possibly a pour pot to help with distribution. The application is sometimes not aesthetically pleasing, but necessary for good long-term maintenance practices and pavement preservation. If this process is performed prior to a sealcoating application then the crack filling material is less noticeable but still evident. Hot rubber crack filling is the best process and offers the longest lasting crack sealing solution for pavement preservation. Most cold pour rubber materials are not as flexible and can open up again within the same year they are applied.  But they still provide good maintenance benefits if performed regularly.

Choosing an appropriate hot-rubber product for your next commercial project depends on what equipment you choose to melt the crack filler and any local or federal specifications you must meet. Below are our hot-applied products matched with appropriate application tools.

Pure Hot Direct Fire Crack Sealant is great to use with our 10 Gallon Hot Rubber Crack Sealer Applicator or 30 Gallon Hot Rubber Asphalt Crack Sealer Kettle.  A direct flame melts the product before application onto pavement.

Our Pure Hot 3405 Crack Sealant meets ASTM D6690 Type II requirements and is compatible with the 10 Gallon Hot Rubber Crack Sealer Applicator or 30 Gallon Hot Rubber Asphalt Crack Sealer Kettle just like the Pure Hot direct fire option.  This product is perfect if your state requires you to meet the ASTM D6690 Type II requirement.

The Pure Hot Pour Joint Sealant for Oil Jacketed Units is specifically designed for those oil-jacketed machines with a layer of oil in between that provides a more steady temperature within the melter. Using an oil-jacketed machine provides reliable application and is a good investment for larger commercial projects. Use this hot-applied product specifically with oil-jacketed applicators.
