The DON’Ts of Applying Anti-Corrosive Coatings

corrosion of metals

Facility managers have learned the lesson not to delay attending to corrosion problems in metal structures, as it is better to prevent them before they get worse and further the damage. And one of their solutions to corrosion-related problems is through painting the exterior of corrosion-prone metal surfaces.

 

The key is to know how to avoid oils, coatings and sprays which only partially protect the surface by simply reducing the ability of moisture and air to reach the metal surface. See below some don’ts of coating to stop corrosion of metals.

 

Choosing the wrong anti-corrosive product

When selecting an anti-corrosive product, prefer the one that is proven effective in protecting metal surfaces. But first, know its functions, the benefits it can provide, and how it reacts to corrosive elements. Settle on a coating that addresses these mentioned aspects to ensure longevity and protection of the metal.

 

The long track record of industry use and success with Unituff coatings (formerly Seal’n’Peel) has proven its position as a market leader. Its proven ability to truly prevent rust onsite, while providing an easy-to-remove solution which is somewhat unparalleled in the market.

 

Not adhering to specifications of a product

A coating product usually comes with a sheet that indicates guides on the preparation, application, and post-application. Not following the specific instructions can jeopardise the application of anti-corrosive coating products, leading to coating failures.

Another risk of failing the steps on dealing with coatings is that instead of having them applied to provide effective protection, they are making the metal surface more vulnerable to corrosion. Wrong application of the coating can make the system weak, allowing corrosive agents to enter the surface of the metal.

 

For example, Unituff coatings (formerly Seal’n’Peel) must be stirred continuously for 5 minutes to ensure the best consistency of the coating to ensure an optimum DFT (Dry Film Thickness).

 

Not taking safety risks seriously

The components of exterior coating products have certain properties that can be a threat to the health of workers that handle the product. This is why it is best to read guides on how to handle and store such products the safest way possible. The guide may include the boiling, flashpoints, and melting properties of the product. Importantly, the product’s toxic properties are also declared in the guide. Knowing these factors will help handlers in preparing first aid for future and unexpected emergencies.

 

Underrating environmental threats

Mishandling coating products can pose a threat to the environment. The application can bring a negative impact to the surrounding provided the chemical risks it carries. If the storage, application, and disposal processes are not handled well, the human health and the environment could be at risk.

 

It all boils down to who is going to handle the coating product to address corrosion of metals. If you are unsure about how to handle the product, speak to someone who has the expertise in applying coatings.
