The use of a clay stabilized asphalt emulsion to fill alligatored surfaces prior to applying a reflective coating is effective because this type of emulsion can provide the necessary flexibility and adhesion to accommodate the existing surface irregularities. Alligatoring refers to the cracking pattern that resembles an alligator's skin, which often occurs due to age, moisture infiltration, and thermal cycling in the roofing material.

A clay stabilized asphalt emulsion has specific properties that enable it to bond well to the underlying surface while providing a smooth base for additional layers. Its adhesive nature helps to seal the cracks and prevent water intrusion, ultimately enhancing the longevity and effectiveness of the roof coating application.

This preparation step is crucial for ensuring that any subsequent reflective coating adheres properly and performs effectively, protecting the roof from further damage and extending its lifespan.
