How Water Tank Paint Protects Against Corrosion

If you have an outdoor water tank, then you may be only too familiar with corrosion. Corrosion is a term that describes the degradation of metals, and it’s something that we’ve all experienced with our water tanks. Over time, your water tank may start to rust.

However, by painting your water tank every year or so with water tank paint (and doing some other maintenance), you can help prevent any issues before they happen.

Let’s dive into what is water tank paint and how it can protect your water storage tanks. 

What Is Corrosion?

Corrosion is a process in which a material breaks down chemically. In the case of water tanks, corrosion occurs when water and oxygen interact with one another to form salt crystals. Yes, don’t forget, water is corrosive. 

The salt crystals can cause damage to your tank over the years by breaking through paint and rusting steel—and eventually leaking all over your floor!

The best way to prevent corrosion is through regular maintenance. This means checking for signs of it, cleaning it up if you find any, and taking measures to avoid future occurrences as much as possible.

There are three main ways you can tell whether there’s corrosion present in your tank.

First, try a visual inspection to see if there has also been water pipe corrosion. Next, check for rusty patches on the surface. These indicate that moisture has been able to reach an unprotected area where it could cause damage (like where pipes enter or exit).

You’ll also want to look out for spots where paint has chipped off completely. If even small amounts of metal are exposed without any coating left behind them, then they might start rusting soon, too!

Why Water Tank Paint Is Important

Water tank paint is important because it protects your water tank from corrosion. The moisture that gets trapped in the paint helps prevent rusting, so when you look at your water tank, you can be confident that it will last for many years to come.

Water tanks are exposed to the elements and may take years before they’re replaced or repaired. You want to make sure that you’ve done everything possible to protect against rusting so that your investment will last as long as possible.

When choosing a water tank paint, consider how thick of a coating you want on your tank. If it’s used frequently (such as livestock watering), then consider using two coats of thickly applied epoxy primer. 

This should be followed by two coats of either enamel or acrylic topcoat. This way, they’ll be more resistant than oil-and-varnish products when exposed directly over time to ultraviolet rays from sunlight exposure. You may also want to invest in a  corrosion inhibitor. 

What Are Water Tanks?

A water tank is a large container that stores water. They are typically used to capture precipitation, store it so that it can be used later, or even collect the rainwater from your roof before it drains away.

Water tanks come in all shapes and sizes, but there are a few things that they have in common. They are made of metal, plastic, or concrete. They should also have a lid to aid your getting at the water. 

There are several different types of tanks: above-ground; underground; and dual purpose, which means it uses both methods. Some water tanks use gravity to move the liquid from one point to another, like from an underground tank into your building). Others rely on pumps powered by electricity or diesel fuel.

Remember that water tanks fuelled by electricity or diesel fuel will be bad for the environment. They are also likely to cost you more in energy bills. Be sure to factor this into your decision. 

How Water Tank Paint Protects Against Corrosion

Water tank paint is a protective coating that helps prevent corrosion. It does this by creating a barrier between the metal and the water. If you want to understand this in greater detail, check out the resources on our learning center for more. 

Water tank paint is made from a polymer resin that is applied to the surface of the tank. This creates an impermeable layer, which prevents oxygen and other gases from reacting with the metal underneath it to create corrosion.

Water Tank Paint Can Help Prevent Corrosion

Keeping your water tank coated in water tank paint can help prevent corrosion as a business owner. Water tanks are an extremely important and valuable part of every building. You must take care of them and keep them maintained as much as possible to ensure that they’re always working properly.

One way you can do this is by applying water tank paint on the outside of the tank, which will protect it from rusting or being damaged by rainwater. This way, if any part of your premises starts to leak, it won’t be able to affect your storage unit.

If you want to make sure that your tank isn’t susceptible to corrosion or rusting—or even just get some peace of mind knowing there’s a protective layer between yourself and those elements—then consider coating it with water tank paint. 

Water tanks are often exposed to the elements, so it’s important to keep them protected from rust and other issues.
