When Is The Right Time To Contact An Asphalt Sealcoating Kansas City Contractor

By Casandra Newton


Driveways and parking lots need to be well maintained. The surface of pavement is affected by weather aspects like moisture, ultraviolet rays and cold. In order to preserve it, it needs to be protected. An asphalt sealcoating Kansas City contractor seal coats the surface to ensure that it is protected and remains in good condition.

When paving surface is constructed, it starts to degrade from effects of heat, cold, water, moisture and salt deposits. It also disintegrates as a result of continuous use and heavy load turning over. A seal coat helps keep the surface free from effects of weather changes. The pavement surface may turn from black to gray and start raveling. The binders loosen and this can results to cracks.

Oxidation and break down of paving binder can be prevented by use of a seal coat. The coat acts as barrier and bars ultraviolet rays, cold, moisture, salt deposits and oils as well as other substances from directly acting on the pave surface. This helps extend the lifespan of your pavement. The contractors allow new paving surface to first cure and this may take about one year.

When a new paving is done, seal coats are not applied immediately. The surface is allowed to oxidize this takes about one year. By curing it means that the oils present on the surface of pavement are oxidized. If a seal coat is applied when there are oils, it may not offer its preservative role properly. This is why time has to be given for new paving surface to cure or oxidize. Through the process of oxidation, the oils eventually reduce and this leaves the surface dry.

When the new pavement surface cures, the first seal coal is applied. The other coatings are applied after 3-5 years. However, the time taken for the successive seal coats to be applied depends on other many factors. The amount of traffic and load that turns on the road is one factor. If there is more traffic turning on your roads, the coat will not last for long. It will take a short time to apply another coat.

The amount of water that runs over the surface also determines how long the coat lasts. Water can wash away the coat and thus necessitate the application of another coat within a short time. This may turn expensive. In addition, if paving surface is mostly on shade, this may help keep the coating in good form for a long time.

Therefore, if there are cracks, they need to be filled before coating. The coat has only preservative value and therefore, any damages on paving surface should be worked on before a coat is applied. If properly repairs and maintenance schedule of your driveways and parking lots is exercised, the roads are able to last for long.

The estimated period that driveways and parking lots can last is about 20 to 25 years if they are maintained properly. There is a need to have a continuous repairs and maintenance program perhaps on a yearly basis. This helps prevent the foundation of roads from loosening up. It keeps the paving surface strong. An asphalt sealcoating Kansas City contractor will inspect your driveways and provide repairs and seal coats that add value on your roads.
