The purpose of seal coating is to protect asphalt from wear and tear. It’s a mixture of chemicals that are sprayed on the surface to prevent it from cracking, crumbling or degrading any further. Sealcoating can be applied to asphalt roads, parking lots and driveways when they are in good condition with no visible damage. It protects against harsh ultraviolet rays that may cause cracks in paved surfaces; water that causes potholes and other forms of damage; as well as traffic which contributes to wear on the surface making it less safe for vehicles passing over them regularly.
What is seal coating?
Sealcoating is made up of two main ingredients, asphalt and coal tar. The coal tar provides UV protection, while the asphalt helps it adhere to the surface. The sand in the seal coating helps provide traction on your driveway or parking lot so you don’t slip when walking across it. Sealcoating can last anywhere from 2-10 years depending on how well you maintain your driveway or parking lot after it’s been applied.
Sealcoating is affordable
Sealcoating is a great way to extend the life of your asphalt driveway brisbane and protect your investment. It can be done at any time of year and will save you money in the long run by preventing more expensive repairs. Sealcoating costs less than replacing damaged areas, which can lead to additional expenses like drainage issues from water damage, cracking or potholes, vehicle damage from uneven surfaces and other problems that may result in higher repair costs later on.
The surface must be cleaned before seal coating
The asphalt must be cleaned before seal coating to remove dirt, dust and other debris that has collected on the surface. Use a stiff broom to remove as much dirt and debris as possible. A hose can also be used to wash away the rest of the dirt and debris on the surface. If you do not have access to a pressure washer, you can use a garden house or hose with warm water to clean your driveway or parking lot.
Its made from an emulsion of materials
Sealcoating is not paint. It is actually a mixture of materials including coal tar that protects it from wear and water, extends the life of asphalt and provides a better surface for driving on. Sealcoat is applied to asphalt roads and parking lots to make the surface look better, protect it from cracking due to weather conditions and extend its lifespan. The sealer is absorbed into the top layer of pavement where it remains flexible until it wears off with use or traffic abrasion.
Sealcoating may not be suitable for asphalt with extensive damage
Sealcoating is best used on asphalt that is in reasonable condition. If your driveway has potholes, loose gravel or large cracks, you may need to have these repaired before you can have the surface seal coated.
Seal coating is highly recommended every 3 to 5 years
