When it comes to protecting welded seams from corrosion, zinc spray is an excellent choice. This quick-drying, durable anti-corrosive agent is particularly effective for any metal, especially in areas prone to rust like welded seams and drilled holes. In this article, we will provide you with top tips for applying zinc spray on welded seams to ensure maximum protection and longevity.
Preparation is Key
Before applying zinc spray, it is crucial to prepare the surface properly. Start by cleaning the welded seam thoroughly to remove any dirt, grease, or rust. Use a wire brush or sandpaper to ensure the surface is smooth and free of contaminants. This step is essential as it allows the zinc spray to adhere better to the metal, providing a more effective protective layer.
Once the surface is clean, make sure it is completely dry. Moisture can interfere with the adhesion of the zinc spray, reducing its effectiveness. If necessary, use a heat gun or allow the metal to air dry before proceeding with the application.
Shake Well Before Use
Zinc spray has a high viscosity, which means it needs to be shaken thoroughly before use. Shake the can for at least one minute after the shaking balls inside the can become audible. This ensures that the zinc particles are evenly distributed within the spray, providing a consistent and even coating.
Failure to shake the can properly can result in uneven application, reducing the protective qualities of the zinc spray. Additionally, shaking the can helps to prevent the valve from blocking, ensuring a smooth and continuous spray.
Application Technique
When applying zinc spray, hold the can at a distance of 8-12 inches from the welded seam. Apply the spray in a steady, sweeping motion to ensure an even coat. It is better to apply several light coats rather than one heavy coat, as this allows the zinc spray to dry more evenly and reduces the risk of drips or runs.
Allow each coat to dry for a few minutes before applying the next one. This layering technique provides a thicker, more durable protective layer, enhancing the anti-corrosive properties of the zinc spray.
Post-Application Care
After applying the zinc spray, it is important to clean the nozzle to prevent clogging. Turn the can upside down and spray until only the propellant comes out. This clears the nozzle of any residual zinc particles, ensuring it is ready for future use.
Store the can in a cool, dry place to maintain its effectiveness. Proper storage and maintenance of the zinc spray can extend its shelf life, providing you with a reliable anti-corrosive solution for future projects.
Benefits of Zinc Spray Over Traditional Paint
Zinc spray offers several advantages over traditional paint when it comes to protecting welded seams. Firstly, zinc spray provides a more durable and long-lasting protective layer. With a zinc dry content of over 90%, it offers superior resistance to corrosion, even in harsh environments.
Additionally, zinc spray is quick-drying, allowing for faster project completion. Traditional paint can take hours or even days to dry completely, whereas zinc spray dries within minutes, making it a more efficient option for metal repair and protection.
Another benefit of zinc spray is its versatility. It can be used on a variety of metals, including cold galvanized and electric galvanized metals. This makes it a suitable choice for a wide range of applications, from fixing damaged zinc surfaces to covering drilled and welded areas.
Conclusion
Applying zinc spray on welded seams is an effective way to protect metal from corrosion. By following these top tips, you can ensure a smooth and even application, providing maximum protection and longevity for your metal projects. Remember to prepare the surface properly, shake the can well, apply in light coats, and clean the nozzle after use. With these steps, you can achieve a durable and long-lasting anti-corrosive layer.
