The Ultimate Defense: Sandblasting and Epoxy Coating vs. Standard Paint for Your Water Tank

Water tanks play a crucial role in providing dust control on construction projects. They are exposed to harsh environmental conditions, and their durability is essential to ensure a constant water supply. When it comes to protecting these tanks from corrosion and wear, two advanced methods stand out: sandblasting and epoxy coating. Below we will explore the importance of sandblasting and epoxy coating versus standard paint when it comes to safeguarding steel water tanks.

The Battle Against Corrosion

Corrosion is the arch-nemesis of steel water tanks. It occurs when moisture and oxygen interact with the steel’s surface, leading to rust formation. Standard paint, while providing some protection, is not as effective as sandblasting and epoxy coating when it comes to tackling corrosion head-on.

Sandblasting: The Cleansing Power

Sandblasting is the first line of defense against corrosion. This method involves propelling abrasive particles, such as sand or aluminum oxide, at high speeds onto the steel surface. The abrasive action of the particles effectively removes rust, contaminants, and old paint, leaving the steel’s surface pristine.

Why Sandblasting is Essential:

1. Prepares the Surface: Sandblasting provides a clean, rough surface ideal for optimal adhesion of coatings.
2. Removes Rust: By eliminating rust, sandblasting prevents corrosion from re-emerging.
3. Ensures Coating Durability: A properly prepared surface ensures that the subsequent coatings adhere and perform better.

Epoxy Coating: The Armor of Choice

Epoxy coatings provide optimum protection against abrasion, turbulence, corrosive fluids, and extreme temperatures. Epoxy coating is not only durable but also resistant to many corrosive substances. Epoxies are a top choice for many industrial coating applications, including steel, metal, concrete, and more.

Why Epoxy Coating is Crucial:

Once epoxy cures, it becomes a hard finished surface. Most equipment manufacturers use white enamel paint because it is cheaper. With enamel paint, you will have to repaint tanks much more often due to rust, and that includes tanks that reside indoors. Epoxy paint coatings will last approximately five years, even if the tank resides outdoors.

Conclusion: The Advantage…Advantage

At Advantage Water Tanks, we understand that the key to a long-lasting and reliable water tank lies in the meticulous process we follow. We start by sandblasting to create a premier surface to work with, removing rust and contaminants while leaving behind a clean canvas. Then, we apply an epoxy primer to enhance adhesion and provide an extra layer of protection. Finally, we finish with high-quality polyurethane paint, ensuring your water tank is equipped to withstand the harshest elements. Steel water tanks that undergo this advanced treatment require less frequent maintenance and repainting, resulting in substantial cost savings over their lifespan.
