Why can I still see the cracks in the asphalt?
Sealer is not designed to fill cracks, it seals the bottom of the crack to protect the base. If seal is applied too thickly, it will become brittle and chip off.
How often should I have my parking lot sealed?
Industry experts recommend that commercial or residential asphalt pavements be seal coated every 2 to 5 years, depending on traffic and overall condition in order to reduce long-term maintenance expenses.
