How It Works

Mighty Sealer will fix cracks and leaks anywhere inside or outside your house by sealing them with a watertight seal. The product is made out of thick, liquid rubber that remains flexible over time and stays put in the same location for years. Its flexibility ensures that it won’t crack or chip, even as the things you’ve sealed shift and undergo small amounts of movement. Besides sealing a crack shut, it will also protect any surface, such as vinyl, wood, metal, or rubber, from further damage.

  1. Bathroom
  2. The clear Mighty Sealer is an ideal choice when you need to seal cracks in your bathroom, including those within the shower, bathtub, grout, faucets, or pipes. It’ll also effectively create a seal around the edge of your toilet, if needed. If you have white pipes, you can use the white version of the product to seal cracks within these.

  3. Kitchen
  4. You can also employ the clear or white versions of Mighty Sealer in order to fix cracks in your kitchen’s countertops, faucets, or pipes.

  5. Gutters
  6. If your gutter develops a leak and begins to gush in the rain, you can select either the white or clear Mighty Sealer to fix up this leak.

  7. Home Siding
  8. If you have white siding, Mighty Sealer in white will effectively repair and conceal any cracks within it. You may want to use clear Mighty Sealer to repair siding of another color, unless it’s a color that looks good with white, like light blue.

  9. Roofing
  10. You can easily fix a crack between the shingles of your roof with black Mighty Sealer, to ensure that water doesn’t start dripping into your home when it rains.

  11. Driveways
  12. Black Mighty Sealer is also ideal for fixing cracks within the pavement on your driveway.

  13. Damaged Trees
  14. If you’ve got a cracking or damaged tree on your property that you want to preserve, repair the holes or cracks with black Mighty Sealer to keep it standing.

  15. Vehicles
  16. In addition to household repairs, Mighty Sealer will repair leaks or cracks on the outside or within the inside of vehicles, including boats and RVs. Select a shade of Mighty Sealer based on the shade of your vehicle’s inner or outer parts that you need to seal.


On the informercial, a vehicle is sealed shut on the sides with Mighty Sealer. Even when it’s filled with water via a hose being run through the top, none of the water leaks out onto the ground.
