Regular resealing of the surface of a driveway or sidewalk can help prevent moisture from moving under the surface material and causing cracks or heaving. Sealants are available for both concrete and asphalt surfaces.
The important thing to remember about sealing a driveway is the weather forecast. To be effective, the surface must be clean and dry before the sealant is applied and should remain dry long enough to cure completely. Some other tips when it comes to sealing the driveway surface include:
- Make sure to purchase a product appropriate for the type of surface you have.
- Water-based sealants will result in a matte finish because they soak into the surface. Oil-based sealants will result in a shiny surface and sit on top of the asphalt or concrete.
- Fill cracks and make repairs before sealing.
- Sealant can be messy and difficult to clean up. Be sure not to track it into a building on clothes and shoes.
