It dawned on us that many of our customers have questions about the sealcoating process. So we have compiled a list of some of the most frequently asked sealcoating questions we could find. These include:
Why are two thin coats of sealcoat better than a single thick coat?
The answer is quite simple. Applying two thinner coats allows the sealcoat to dry and cure much faster than one thick application. Sealcoating is water-based and cures through evaporation. Because of this, the top layer dries faster than the bottom layers. If applied in one thick coat, sealcoating has a tendency to hold water and stay soft for a long period of time.
One thin coat of sealcoat looks good enough; why do I need a second coat?
Aesthetics is only part of the reason for sealcoating. The larger purpose for this process is to protect the asphalt underneath. One thin coat only provides half the necessary protection.
Applying one thin coat also means that you will have to sealcoat more frequently.
Why does sealcoat fail or peel?
Oil spots and other contaminants, like grease and dirt, will prevent the sealcoating from properly bonding with the asphalt. This is why the pavement should be thoroughly cleaned before the sealcoating process begins.
Why are there white streaks in the sealcoating?
This could be a sign that there is a problem with your base. The limestone from the base may be making its way through pre-existing cracks in the pavement.
