Asphalt Sealcoating

The most important part of any pavement management plan is sealcoating.  Sealcoating your parking lot preserves the asphalt for pennies per square foot and protects pavement surfaces against gasoline, oil, salt, water, and ultraviolet rays. Shamrock Asphalt has the experience and capability to sealcoat any size parking lot from very large amusement parks or industrial parking lots, to very small lots.  Sealcoating asphalt consists of two applied coats, with a spray unit, a squeegee machine, or brush applied pavement sealing.

Asphalt and Parking Lot Sealcoating Benefits

Regular Sealcoating Beautifies

• Regular parking lot sealcoating projects a positive image of the company, facility, or residential apartment complex / condo association.

Sealcoating slows water penetration and oxidation

• Sealcoating minimizes the speed and quantity of water entering the asphalt. If left un sealed, water can penetrate more freely which will result in cracking and expansion and contraction of the asphalt. 
• Sealcoating reduces exposure of the asphalt to oxygen and UltraViolet rays and limits how far oil and gas can penetrate into the pavement.

Sealcoating resists oil and gas spills

• The coal tars that are used in sealcoat products are impervious to gas and oil spills. Petrolium products that settle into ashpalt can break down or soften asphalt that is unsealed. 

Asphalt that is sealcoated is easier to clean

• Sealcoats fill surface voids resulting in a smooth and even texture. The smooth surface sheds water and makes snow easier to remove. Sweeping is fare more effective on a smooth surface. 

Sealcoating asphalt increases pavement flexibility

• The darker the pavement the more heat the pavement retains from the sun, the hotter it becomes the more pliable and flexible the pavement. This helps withstand heavy or frequent traffic without cracking. 

Sealcoating protects asphalt from pressure washing

• It may come to the point when a parking lot needs cleaned with a pressure washer, sealcoating protects asphalt and parking lots from the water pressure and detergents used in pressure washing.

Sealcoating Application Methods

Sealcoat Brush Application

The brush application is generally used when sealcoating smaller and more restricted areas. With the brush application the sealer is forced down into the voids and small hairline cracks, thus filling these areas. The brush process allows for more solid material in the sealer mix for a much thicker coat as well as uses approximately 40% more sealer material than standard 2 coat spray application. After the squeegee coat is dry, we follow with a spray coat, thus providing a coating on the high ridges of the pavement, leaving a build up of material on these ridges, something the squeegee machine can't do. Thus you are getting the ideal application of sealer, working the material into voids, hairline cracks, and porous areas, followed by the build up of sealer on the ridges of the asphalt, providing a nice finish.

Sealcoat Spray Application

Spray applications are used for all conditions of asphalt / blacktop surfaces. 2 coat spray applications add beauty and protection to your investment as well as curb appeal in a very competitive real estate market.

Sealcoat Squeegee Machine Application

Squeegee machine application is highly recommended for new asphalt that has not had seal coating material yet applied. The sealer is forced down into the voids and small hairline cracks, thus filling these areas. The squeegee machine process allows for more solid material in the sealer mix for a much thicker coat as well as uses approximately 40% more sealer material than standard spray applications. After the squeegee coat is dry, we follow with a spray coat, thus providing a coating on the high ridges of the pavement, leaving a build up of material on these ridges, something the squeegee machine can't do. Thus you are getting the ideal application of sealer, working the material into voids, hairline cracks, and porous areas, followed by the build up of sealer on the ridges of the asphalt, providing a nice finish.

Sealcoating Process

1. Thoroughly clean asphalt area with broom and industrial power blowers.
2. Edge all grass areas that join to asphalt.
3. Apply oil spot primer where necessary.
4. Apply 2 coats of coal-tar commercial grade sealer with brush, spray or squeegee (depending on environment and need)
5. Restripe/Paint to existing layout.
6. Provide barricades to close off area until ready for traffic.
