Since asphalt is a petroleum product, other petroleum products will react with the surface. This includes vehicle oil and gasoline. The sealcoat will act as a barrier against those materials. Sealcoat can save an owner huge costs over the life of asphalt pavement.
Periodic asphalt maintenance such as sealcoating will extend the life of the asphalt up to 30 years. New asphalt surfaces sealcoated within their first year will experience less degradation from UV damage, water and traffic.
Sealcoating prevents oxidation caused by harsh weather conditions and by sealcoating annually, asphalt can be preserved for an extended period of time.
Sealcoating also saves property owners from spending money on costly asphalt repairs.
