Galvanization is a process that is being used for more than a century to prevent damaging effects of corrosion on metal surfaces. The Galvanization of steel and iron products is generally chosen due to their low maintenance, low cost, sustainability, aesthetics, and long life.
In 1837, in France and England, the process of galvanization was simultaneously developed where a coating of zinc was applied to an iron surface. The method used back then involved manually dipping the iron sheets into hot molten zinc. Within two years, the galvanized iron sheets became common for roofing applications in the U.S.A and Europe.Now, the process is easily completed by using the galvanizing spray in India and the world. Zinc spray galvanizing is a very easy cold galvanizing process where the coating is put on a steel surface only by spraying it or painting it with the zinc.
The zinc coating offers outstanding corrosion resistance for iron and steel objects and structures used in several environments like industrial, marine, and other atmospheric conditions. One generally uses zinc spray for the components that cannot be rinsedinto a galvanizing bath because of their large size or are prone to losing their shape due to hot-dip galvanizing.
How Is Hot Dip Galvanizing Different From Cold Galvanizing?
The two processes are different. In hot-dip galvanizing, steel and iron surfaces are immersed into hot and molten zinc bath, whereas, in cold galvanizing, the exteriors are paining with zinc-rich paints via the application of zinc dust mixed with inorganic or organic binders using spray or brush. Commonly containing up to 95% of metallic zinc, the zinc-rich paints are generally applied to pipes and structural steel which are exposed to several corrosive atmospheric environments like power plants, buildings, mining equipment, bridges, refineries, etc. Due to high zinc percentages, these paints can combine well with the corrosion inhibitive characteristics of metallic zinc.
What Is Zinc Galvanizing Spray?
Zinc galvanizing spray is an effective touch-up zinc spray that offers cold galvanizing paint coating for protecting any metal surface from corrosion and rust on non-ferrous as well as ferrous metal surfaces. Using the spray is a very convenient option because the smooth flowing spray stops corrosion and rust on all metal surfaces. The spray puts on a zinc-rich coating that bonds with metal electro-chemically. It also forms a permanent, highly adhesive, and fast drying primer layer on the metal surface to protect it from corroding and catching rust outdoors or indoors.
Uses of Zinc Galvanizing Spray
To repair damaged steel structures or galvanized surfaces.Acts as protective paint on woodwork, steel, iron, piping, roof coverings, galvanized sheet iron, etc. It allows the deposition of a metallic zinc coating that prevents the metal surface from corrosion and rust.
Works as a water-resistance layer on marine equipment and offshore steel structures in order to protect them from corrosion. It can be used on telecommunication towers as well to prevent them from rusting due to rain. It is employed in the galvanized grating, steel tubes, steel pipes, cable trays, etc.
Widely used in substation and power plant equipment.
It can also be utilized as the primer on galvanized fences, gutters, trailers, trucks, ducts, etc. The spray helps enhance the life of parts and underbodies of bikes, cars, automobiles, etc. It can be used in homes to beautify corroded iron pipes and surfaces.
How To Use Zinc Spray?
Using the zinc spray is not a complex process and if you want to repaint any surface of your house and give it protection from corrosion and rust, you can invest in a zinc spray. You can use it without any external help, however, you must keep the following tips in mind.
Always shake the spray bottle well before using it. Shake it vigorously for a minute or two so that the mixing balls in it starts to rattle and mix the paint.
Then, spray via the nozzle of the can by maintaining a distance of at least 15 cm.Keep the bottle in motion while spraying and shake whenever necessary.
Apply a thin layer for the best results.
Check on a small patch of the surface before final use.
Make sure the area is well ventilated.
After using the spray, put the cap on the bottle and store it safely.
Do not touch the surface immediately and for best results, allow the paint to dry for a few hours.
Wear gloves to protect your hands.
Keep the bottle away from the reach of your pets or children.
You can also put tape or paste paper near the surface so that you do not accidentally spray and damage nearby areas.
The Bottom Line
Instead of replacing corroded metallic objects or things with a layer of rust, you can apply a thin layer of zinc using galvanizing sprays. The process is possibly the easiest one, if highly effective, increases life, and is also a cost-effective method to protect the damaged metallic surface.
