Sealing cracks is simple with Asphalt WelderAlligator Glue, or Elastic Cement AC for asphalt repairs, or Concrete WelderDopey Soup, or Elastic Cement for concrete repairs in dual cartridges.

Make sure the crack is clean and free of moisture. If there is a lot of water, use a blow dryer or torch to make certain the crack is dry. Open cartridge and squeeze directly into the crack. Use a scraper or straight-edge to smooth the material out. Wipe up any excess material and allow to dry for 30 minutes. Now the crack is filled and ready for use.



Concrete Welder and Asphalt Welder are low viscosity, penetrating polymers combined with high strength silica fillers to create a simple-to-use repair kit. Repairs cracks, divots, rutting and spalling.  One bottle contains polymers, pigments and silica fillers.  Another bottle contains the catalyst. A spout is attached for combining, mixing and easy pouring.  Neat repairs (without mess) are easily achieved.  Repairs are ready for traffic within 30 minutes at 75 degrees Fahrenheit. Click here for instruction sheet.
