Surface Preparation: Key to Protective Coating Excellence

Surface Preparation: Key to Protective Coating Excellence

The old adage “preparation is key” couldn’t ring truer when applied to protective coatings in the corrosion prevention, water, and wastewater industries. Whether safeguarding a water storage tank against the elements or enhancing the lifespan of wastewater treatment process equipment, applying protective coatings is only as effective as the surface preparation performed before it is applied.  V&A’s new blog post discusses the significance of surface preparation and provides an overview of industry standards. Protective coatings offer the first line of defense against the harmful effects of a corrosive environment on infrastructure.

Protective Coatings on Welded Steel Storage Tanks: Is It Time to Repair or Replace?

Protective Coatings on Welded Steel Storage Tanks: Is It Time to Repair or Replace?

The decision to repair or replace a protective coating on welded steel storage tanks depends on several factors, including the condition of the existing coating, the extent of damage or deterioration, the remaining service life of the storage tank, budget considerations, and environmental considerations.

Generally, a high-quality protective coating on a well-maintained welded steel storage tank can sometimes have a lifespan of 20 to 40 years or even longer. However, premature coating failure can occur due to various factors, and ongoing inspections and maintenance are crucial to ensuring the longevity of the coating.

Protecting Infrastructure – What’s the Difference Between Coatings and Linings?

Protecting Infrastructure – What’s the Difference Between Coatings and Linings?

Protective coatings and linings are regularly discussed in the corrosion, water, and wastewater industries. Often, coatings and linings offer the first line of defense against a corrosive environment's harmful effects on infrastructure. The term coatings is generally used for protective materials on a valve, pipe, tank, or sheet pile exterior. The term lining is usually used to describe the protective materials on the interior surfaces of a valve, pipe, tank, or concrete structure.

The First Line of Defense: Coatings and Linings

The First Line of Defense: Coatings and Linings

One of the largest challenges the nation faces is deteriorating infrastructure. Not only is this a result of old age and natural wear and tear, but also from harsh environments that some of our infrastructure have to exist in. The deteriorating effects of these environments can be delayed and protected against simply by applying a coating or lining system. We will briefly discuss some common harsh environments that water and wastewater infrastructure must be able to survive in and that coatings and lining systems offer the first line of defense in extending and preserving their service life.
