A pavement that has been sealed with a coal tar sealer is highly resistant to gas and oil. The deterioration process caused by fuel and oil spills will be severely curtailed. Coal tar sealer is also highly resistant to the sun’s ultraviolet rays, which dry out the pavement, causing it to ravel and lose its flexibility.
St. Louis Paving uses only high quality, commercial/industrial strength sealer, each gallon of which contains 4-6 lbs. of sand on a standard application. For an additional fee, our experts can mix in curing additives.
St. Louis Paving can mix a custom sealcoating solution of sand (for strength and skid resistance) and latex modifiers (for elasticity and hardening). Parking lots are typically sealcoated every 2-3 years.
