Sealcoating in Austin TX


What is Sealcoating?

Sealcoating is the process of applying a coal tar emulsion over an asphalt pavement. Also known as pavement sealing, this process applies a new protective coating to an asphalt pavement to protect against oil, water, and UV damage. Regular asphalt sealcoating in Austin, Texas can double the lifespan of your asphalt lot or driveway with significant cost savings. 

Your asphalt surface is essentially gravel, rock, and binder material called asphalt cement that holds the aggregate together. Asphalt cement is made by distilling crude oils. Over time, chemicals, UV exposure, and rain all degrade the binder and cause deterioration of the asphalt surface and brittleness. 

Asphalt sealcoating creates a barrier to reduce this damage and extend the longevity of the asphalt surface. A new sealcoat also improves the appearance of your asphalt with a bright, black finish. 

Sealcoats are typically liquid formulas made from acrylics or bituminous-based ingredients that are applied with a squeegee, spray, or brush. There are many varieties of asphalt sealers, each with different applications and benefits. 

Acrylic Sealers

These sealers are fairly expensive but offer the most benefits. Acrylic sealcoats come in a range of colors and contain no petroleum byproducts. They are typically used for outdoor game courts but they're also popular for parking lots. An acrylic sealer offers excellent durability, UV resistance, and longevity. 

Fast Dry Sealers

This type of sealer is used to patch a parking lot or road as it can cure in less than an hour thanks to geo-textile fibers. Fast dry sealers are best used for critically damaged areas of asphalt pavement. 

Coat Tar Sealers

This is the most popular type of asphalt sealer with excellent weather resistance and a long-lasting finish. Coat tar sealers have a large amount of coal tar along with additives and polymers. 

Asphalt Emulsion Sealers

These sealers are asphalt-based products and an eco-friendly alternative to coal tar sealers which are linked to health risks. An asphalt-based sealer is an excellent way to protect your asphalt driveway or parking lot while preserving your air quality. The primary downside to this type of product is it's prone to stains from auto fluids. 

What does it do?

Sealcoat protects your asphalt from the damaging effects of the environment, including moisture and ultraviolet oxidation. After cracks in the asphalt are repaired, a sealcoat effectively creates a new barrier against the elements while giving your asphalt a newly paved look. Sealcoating asphalt in Austin protects your asphalt surface from the elements for years to come and extends the life of the asphalt. 

Is Sealcoating Asphalt Necessary?

While not strictly necessary, sealcoating does extend the life of your asphalt parking lot or driveway and prevents premature wear and tear. Regular asphalt sealcoating is a cost-effective solution to double the lifespan of asphalt and maintain its sleek, black appearance. 

Asphalt sealcoating isn't expensive and helps protect your asphalt surface from:

  • UV damage
  • Rain
  • Ice
  • Car fluids like antifreeze, gas, and oil

You don't need to sealcoat asphalt every year as sealing the surface too often will cause excessive buildup, cracking, and damage. Instead, asphalt sealant should be applied every few years. 

Why do you need sealcoat on your parking lot?

There are many benefits to sealcoating the asphalt to your driveway or parking lot. Think of sealcoating more of as a preventative maintenance for your diveway or parking lot. 

  • Sealcoating the asphalt, seals the small cracks that can turn into large cracks and prevents water from seeping down to the base material. 
  • The dark black color of newly applied sealcoat improves the appearance of new and old asphalt, making your driveway or parking lot look near brand new. 
  • Another benefit of sealcoating, is that it helps protect the asphalt from the sun as well as the harmful effects of chemical spills such as oil and gasoline. 
  • Sealcoating acts as a waterproofing agent, minimizing the rate at which water enters the asphalt. Sealcoating asphalt prevents the seepage of water and moisture from rain and snow, thus preventing damage from freeze thaw cycles which is a common reason your driveway or parking lot begins forming cracks or even worse, alligator cracks.
  • Sealcoating provides an attractive black surface that is ideal for painting lines and other markers on parking lots. Sealcoat is a dark, black colored matarial and when applied to asphalt, it helps attract more heat from the sun. The hotter the sealcoating on the asphalt gets, the more pliable it becomes, which helps it to withstand traffic without cracking. 
  • Sealcoating fills surface voids, which reduces exposure to oxygen and UV rays and reduces the depth to which oil or gas can penetrate the asphalt. 
  • It acts as a waterproofing agent, minimizing the rate at which water enters the asphalt of your driveway or parking lot. The intrusion of moisture into asphalt accelerates its deterioration.
  •  Sealcoating seals the asphalt pavement, preventing the oxidation and erosion of the top layer and replaces fine particles lost from the asphalt surface due to oxidation on older pavements.
  • Sealcoating preserves asphalt for pennies per square foot, verses costly asphalt repairs. 

Our Procedure

  1. First, TexAsphalt thoroughly cleans your pavement using a combination of wire brushes, power brooms, power blowers and where necessary, power washers. We also, where appropriate, trim the grassed edges of your pavement, removing the grass and dirt, allowing us to seal the edges of your pavement where deterioration usually starts.
  2. After the pavement is thoroughly cleaned, we start the seal coating process. Our process involves applying an emulsion based seal coat material with 3 lbs of sand per gallon added to the emulsion. We squeegee brush the edges with sealcoat to prevent over spray onto concrete. We apply the seal coat in two coats. The first coat is applied by the spray method. Once the first coat is dried we apply a second coat which is also sprayed on.
    1. Where appropriate, to prevent staining of those surfaces, small brushes are used to cut-in adjacent to curbs, aprons, sidewalks, etc. Please note: where cutting in is necessary and appropriate, you may notice a darker shade resulting from additional material in those areas. The shading is unavoidable; but in time, these areas will blend in with the rest of your driveway.
    2. Heavily alligatored areas are double seal coated or treated with a special, very thick material to help cover and stabilize those areas where your driveway has a base failure. This is not a permanent solution, but a time buying procedure which cannot be guaranteed.
  3. Once the seal coat process is finished we barricade your driveway(s) with caution tape or construction cones for 24-48 hours
