North Atlanta Asphalt Sealcoating Contractors
It is important to protect asphalt driveways and parking lots from weather damage by applying an emulsified sealant. Emulsified sealant is an oil-based sealant that has been diluted with water. After application, water will evaporate leaving the oil and solids to bind to the asphalt. That creates a protective barrier preventing the seepage of water into the asphalt which will damage it from within.
Categories of Asphalt Sealcoating
All asphalt surfaces, driveways or parking lots are different and may require the use of different kinds of sealcoat. There are 3 main types of asphalt sealcoating.
- Refined Tar-Based (Coal Tar Based)
- Asphalt-Based
- Petroleum-Based
Seal coat is typically diluted 10% with water to allow it to seep freely into the surface. Be sure the contractor you choose is using the proper ration of water to sealant. Some paving companies may be able to offer a low price by skimping on the amount of sealant resulting in an inferior result.
