How it works

Three steps. One afternoon.

No melter, no mixing, no crew. If you can pour from a jug, you can do this.

  1. 1

    Clean the crack

    Clear out loose debris, dirt and weeds. If weeds are growing in the crack, treat them with an herbicide about a week before you fill so they don't come back through.

  2. 2

    Pour it in

    Pour Tornado Crackfiller straight into the crack until it's level with the surface. The heavy-bodied formula fills the crack without running all over the pavement.

  3. 3

    Level and let it cure

    Smooth any excess flush with the included leveling tool. Let it fully cure before sealcoating, striping or driving on it.

Watch the full application, start to finish.

The result

Cracks that disappear into the asphalt

Most fillers leave a shiny, raised strip you can spot from the street. Tornado dries to a dark matte finish that sits flush and blends in.

  • Self-leveling, sits flush with the surface
  • Keeps water out of the base, where real damage starts
  • Stays flexible as pavement expands and contracts

FAQ

Questions before you start

Tornado or Gator-Nado: which do I need?

Use Tornado for individual cracks and seams. Use Gator-Nado for "alligator" cracking, where the asphalt has broken into a web of connected cracks. Gator-Nado has sand built in and is spread with a squeegee or trowel to lock those sections together.

1 gallon or 5 gallon?

Same formula in both. The 1-gallon jug is sized for DIY jobs and comes with the Buy 2, Get 1 Free deal. The 5-gallon bucket is the contractor size for big driveways, parking pads and lots.

Do I need to mix or heat anything?

No. Tornado Crackfiller comes ready to use. Pour it straight from the jug or bucket, no melter, mixing or dilution needed.

What tools do I need?

Something to clean the crack (a broom, wire brush or blower) and the leveling tool that comes with your order. A squeegee works too for spreading excess.

What about weeds growing in the crack?

Pull what you can and treat the area with an herbicide about a week before applying, so nothing grows back through the repair.

Can I sealcoat over it?

Yes. Let the crack filler fully cure first, then sealcoat, stripe or open the area to traffic.

Can I use these on concrete?

No. Tornado and Gator-Nado are made for asphalt. For concrete, use Mix Master Concrete Repair Mortar.

Working on concrete?

Tornado is for asphalt only
