What are the two types of asphalt primer components?

The two types of asphalt primer components are generally classified as Type I and Type II. This classification is crucial because each type is formulated for specific applications and conditions in built-up roofing systems.

Type I primers are typically designed for use on surfaces that require a fast-drying component or are intended for use in colder weather conditions. They are formulated to enhance the adhesion of the roofing membrane to the substrate efficiently.

Type II primers, on the other hand, are generally used for a broader range of applications and may contain a higher percentage of asphalt, making them suitable for different surface types and conditions. Understanding these distinctions helps roofing professionals choose the right primer for their specific project needs, ultimately ensuring better performance and longevity of the roofing system.

This classification not only aids in the effective application of roofing materials but also ensures compliance with relevant building codes and standards.
