How often should asphalt be sealed?

This is a difficult question. There are so many variables. For one, you have the quality of the installation of the original asphalt pavement. Then there is the question as to whether the Asphalt has been previously sealed, with which product, and how many times. Also customers’ views tend to vary! While some wait until much of the protection is gone before having it resealed, others feel that once it no longer "looks new" it is time to reseal. Nonetheless, once you have applied liquid asphalt to your asphalt the protection continues long after all traces of the sealer seem to be gone.  more
