Potholes form when water seeps down through cracks in the asphalt surface and freezes between the asphalt surface and the sub-base. Over the course of time, this process will eventually force the asphalt surface to sink down below surrounding sub-base, forming the pothole. Pothole sizes can range anywhere from a few inches to a few feet. Sealing your driveway is the best way to prevent these pesky potholes.
- Kill weeds in cracks before sealing. Weed killing products can be purchased at your local hardware or department store. It may take up to a couple days before the product fully disposes of the weeds.
- Clean off dirt, debris, and other loose particles on your driveway. If these loose particles get mixed in with the sealer, it can create an uneven finished surface.
- Create a buffer between your driveway and yard by edging your driveway with a shovel. This will prevent grass and weeds from slipping under the asphalt sealer and will also prevent asphalt sealer from staining your yard.
- Seal cracks and holes with crack fillers and patches.
If you are sealing your driveway by yourself, use rubber squeegees for application. Avoid plastic squeegees because they tend to spread the sealer inconsistently. Once your driveway is sealed, wait 6 – 10 hours before applying a second coat. A driveway that has not been sealed recently will require more sealer to fill in cracks and holes.
Anyone with sensitive skin should avoid contact with wet asphalt sealer. Make sure to remove shoes and other articles of clothing that have been exposed to wet sealer before entering your house. If you have any sealer left over, store it at room temperature, or around 50 degrees Fahrenheit. If asphalt sealer freezes, it will ruin the batch.
