A coal tar sealant protects asphalt from climate conditions. Learn when to add a sealant to a newly paved surface. Then, review the application process that an asphalt contractor will conduct.
Fresh asphalt is flexible and will take several months to cure. If a sealant is applied too quickly, the natural oils found in asphalt will be locked in. This will prevent the asphalt from curing properly and will leave it susceptible to blemishes. Heavy items that are applied to an asphalt surface that has been sealed prematurely could scratch the surface of the asphalt.
Your contractor will advise you on how long to wait to have the new asphalt sealed. Fresh asphalt is durable and is not likely to become damaged right after it is installed. Sealers are usually installed during the warmest months of the year. Warm weather will aid with proper adhesion. Your contractor may advise you to wait until spring or summer to have the new asphalt sealed.
Before a coal tar sealant is applied to asphalt, your contractor will prep the work area. They will clean the asphalt, repair any inconsistencies within the surface of the pavement, and lay protective materials across the exposed property that is adjacent to the pavement. These touchup processes will support an even application of the sealant. The sealant will be a consistent color and thickness once it is applied to asphalt.
Applying asphalt sealant requires the use of a squeegee or a roller. Your contractor may use both types of tools to spread the sealant across the surface of the pavement. The sealant requires time to dry, which will prevent you from being able to use the pavement for the time being.
Your contractor will advise you on how long to wait before you resume using the asphalt. Once the curing process is complete, the sealant will be waterproof. It will protect the asphalt from UV rays too. The protective coating will prevent the asphalt from chipping or cracking.
Coal tar sealants wear down over time. The amount of foot traffic or vehicular traffic that comes into contact with the asphalt may influence how soon the sealant will wear away. Your contractor will advise you on having a secondary coat of sealant applied. Typically, an inspection of the pavement will be conducted. Then, if the sealant shows signs of wear, an appointment for a reapplication will be scheduled.
