What is the general application method for hydrants in terms of coating?

The best method for applying coatings to hydrants involves using both a primer and two coats of paint. This approach is essential for ensuring maximum protection against corrosion and environmental damage.

Priming hydrants first serves an important purpose; it creates a bonding layer that helps the subsequent paint adhere better, preventing issues such as peeling or flaking. The primer also acts as a barrier to moisture and rust, which are critical factors in maintaining the hydrant's integrity and functionality over time.

Applying two coats of paint provides an additional layer of protection and enhances visibility. A high-quality exterior paint specifically designed for metal surfaces is typically used, which helps to resist weathering and fading.

In summary, the combination of a primer and a sufficient amount of paint ensures that hydrants remain durable and functional in various environmental conditions, thereby extending their lifespan and maintaining their operational readiness.
