Which statement about glaze coats is correct?

The correct statement about glaze coats is that they are usually temporary coatings. Glaze coats are applied as a protective layer on roofing materials and are designed to enhance the surface as well as provide short-term protection from UV rays and environmental elements. Their temporary nature means they typically need to be reapplied periodically as they can wear down over time due to exposure to weather conditions or foot traffic.

In contrast, the other statements do not accurately describe glaze coats. While they may offer some level of short-term protection, they are not intended for long-term use like some other protective coatings. Additionally, glaze coats are not meant to be left exposed permanently, as doing so may compromise their effectiveness. Lastly, they do not require no follow-up treatment, as routine maintenance and reapplication are necessary to maintain the roof’s durability and performance.
