3 Reasons To Apply A Protective Coating To Your Decorative Pavement

by Minnie Larson

You will see a lot of asphalt paving materials in a city setting. This is because asphalt is an affordable material that is easy to work with. Thanks to the invention of asphalt stamps, cheap pavement can be transformed into a variety of attractive surfaces.

Pavement stamps can help your asphalt mimic the appearance of hand-laid brick, create decorative impressions, or add interest to your property. Sealing your decorative pavement with the right protective coating is critical when it comes to extending the life of your stamped asphalt.

1. Protective coatings prevent water infiltration.

Water is one of the most destructive elements that asphalt can come into contact with. The materials used to create asphalt as porous once they have been cured. This means that water can seep into your pavement and settle between the asphalt particles.

As temperatures rise and fall, the water will freeze and thaw repeatedly. This expansion and contraction creates cracks that can cause your paved surfaces to deteriorate. Applying a protective coating seals in your asphalt and makes your paved surfaces impervious to water penetration.

2. Protective coatings lock in oils.

Asphalt paving is soft and supple because of the oils that are included in the paving mix. Over time, these oils dry out. This drying process causes your asphalt to become brittle and start to deteriorate.

A protective coating is applied over the top of your decorative paved surfaces as soon as they cure. This locks in the natural oils in the asphalt, helping your paved surfaces retain the flexibility they need to support the weight of foot and vehicle traffic without crumbling.

3. Protective coatings reflect heat.

Another element that can wreak havoc on the quality of your asphalt paving materials is extreme heat. Paved surfaces are exposed to the sun's rays throughout the day. Since most asphalt is dark in color, it attracts the heat of the sun and absorbs it. The resulting rise in the temperature of your asphalt can cause the aggregate mix to begin to separate, leaving your pavement vulnerable to serious damage.

A protective coating can act as a shield for your asphalt. Any UV rays that come into contact with the protective coating will be reflected back into the atmosphere. This prevents your pavement from absorbing excess heat and helps ensure that any designs stamped into the surface of your asphalt will remain clean and crisp in the future.
