3 Reasons Asphalt Crack Sealing Is A Lot Harder Than It Looks

Asphalt has a stellar reputation for its lasting capabilities. However, the material can crack open with age and exposure to the elements throughout the years. You can pick up asphalt crack sealer products at just about any home improvement store, but the project is best left to professional asphalt crack sealing services. Here is a look at why this task is far harder than it looks. 

You have to be careful about the current weather conditions. 

Crack sealer products that you buy at the home improvement store will all have different guidelines to follow regarding the climate or weather. Obviously, it is best to do the job when it is dry and you are not expecting rain for a few days. However, there can be other factors that have to be looked at as well, such as what the temperature is that day or how high the humidity levels are, as both of these can affect the consistency of the product and how quickly it will cure. 

You have to use the right crack sealer product for your specific asphalt. 

Asphalt may all look the same, but it can have different compounds in it depending on who installed the material and what formula they used to mix the materials. For example, some asphalt will have a higher ratio of aggregate to tar or vice versa. This composition can affect how well a crack sealer product will adhere to the crack during application. For example, asphalt that has a lower tar level may not adhere as well to some types of crack sealer. When you work with a professional for asphalt crack sealing, they will actually mix a precise type of sealer formula that is specific to your type of asphalt. 

You have to properly prepare the crack before you apply the sealer. 

Before you apply the first layer of sealing material to the cracks, you have to properly prepare the area. This involves getting rid of small granules of dirt and debris, making sure the crack is dry and not holding water, and removing any spots that have flaked or cracked. You can achieve most of this by brushing the crack thoroughly with a good wire brush, but even the smallest particles can cause issues with adhesion after you apply your layer of sealer. It is not uncommon for professionals to use special equipment to slightly grind the crack so it is more receptive to the sealer.
