Purpose of Sealcoating
Reading Time: 3 minutes

Sealcoating, also called pavement sealing, is a process that involves applying a layer of protection to asphalt surfaces like driveways, parking lots, and roads. This is done by coating the surface with either coal tar pitch or asphalt emulsion. The coating serves to protect the asphalt from weather and chemical damage, prevent water from penetrating and causing damage, as well as improve its appearance.

Sealcoating: An Essential Maintenance Procedure For Driveways And Paved Surfaces

The purpose of sealcoating is to extend the life of asphalt surfaces, reduce maintenance costs, and enhance their curb appeal. The following are some of the reasons why sealcoating is essential for any asphalt surface:

  1. Protection From Weather And Chemicals – Asphalt surfaces are exposed to various elements that can cause damage to them. Water, sunlight, and air are the main culprits that cause oxidation, which results in the breakdown of the asphalt binder. This breakdown leads to the formation of cracks and potholes, which can further exacerbate the problem. Sealcoating helps to prevent this damage by creating a barrier between the asphalt surface and the elements. This barrier protects the asphalt from weather and chemical damage, which means that it lasts longer and requires less maintenance.
  2. Preventing Water Penetration – Water penetration is one of the leading causes of asphalt deterioration. When water penetrates the surface of the asphalt, it seeps into the subbase, causing it to soften and weaken. This leads to the formation of potholes and cracks. Sealcoating helps to prevent water penetration by filling in small cracks and sealing the surface of the asphalt. This prevents water from seeping into the subbase and causing damage.
  3. Enhancing Curb Appeal – Sealcoating can give asphalt surfaces a fresh new look, enhancing their overall curb appeal. A freshly sealcoated surface looks clean, neat, and professional. It can also make the surface safer by providing better traction for vehicles and pedestrians, preventing accidents.
  4. Reducing Maintenance Costs – Proper maintenance of asphalt surfaces can be costly, but sealcoating can help to reduce these costs. By protecting the asphalt from damage, sealcoating reduces the need for repairs and resurfacing. This means that maintenance costs are significantly reduced, which is a significant benefit for property owners.
  5. Increasing Property Value – Sealcoating can also increase the value of a property. A well-maintained driveway or parking lot adds to the overall appeal of a property, making it more attractive to potential buyers. It can also help to prevent damage to vehicles, reducing insurance claims, and increasing overall safety.
  6. Extending The Life Of Asphalt Surfaces – Perhaps the most significant benefit of sealcoating is that it extends the life of asphalt surfaces. By protecting the surface from damage, water penetration, and oxidation, sealcoating helps to preserve the structural integrity of the asphalt. This means that the surface lasts longer and requires less maintenance.

Types Of Sealcoating

There are generally two different types of sealcoating used for asphalt surfaces. The first type is called coal tar sealcoat, which uses a solvent-based coal tar emulsion mixed with water and mineral fillers to form a protective coating over the pavement surface. This type of sealcoat is more resistant to ultraviolet rays, oil spills, and moisture, and it also resists cracking and peeling.

The second type of sealcoating is known as acrylic sealcoat, which uses an acrylic polymer emulsion mixed with water and mineral fillers to form a protective coating over the pavement surface. This type of sealcoat is more flexible than coal tar sealcoat, allowing it to move with the asphalt better while still providing protection.
