How Does Paint Protect Iron from Rusting?
Most of the glass boards we’ve seen use a layer of glass that is about ¼” thick (5-6mm). A magnet at the surface has to reach across that distance to attract the steel underneath. A modestly sized magnet that sticks well to a refrigerator or regular whiteboard won’t be strong enough to hold well to a glass whiteboard.
Bigger magnets are needed.
We certainly have bigger, stronger magnets that can hold. Unfortunately, picking the right magnet isn’t so simple. If you just choose really big magnets, they might attract each other much more than the steel underneath. This can make an unpredictable, slamming-together mess.

We apply paint on objects made of iron not only to make them look attractive but also to prevent them from rusting.
Now, what is rusting? When iron is exposed to moisture for a long time, it acquires a coating of brown, hard coating on it called rust. Which is developed because iron easily reacts with water and air, which results in rusting of any object made of iron. This whole process of rusting of iron is called corrosion. It happens not only on iron but on many other objects which form a hard layer on an object but of different colour. There is a condition that iron will only rust when it is in contact with water and air for a long time without any protective layer on it.
The rusting of Iron can be prevented by painting, oiling, greasing, etc. These things create a protective layer on iron, which prevents iron from coming into contact with air and water.
Example- We all have seen iron nails in our household which are used to hang things. When they are new, they appear silver or have a shiny luster on them. But after 2 or 3 months, if you notice the same nail, it will appear to have a brown, hard layer coating on it. That is rust.
On the other hand, if you see the cycle that we all had as kids or have. Some part of it is made of iron, which is painted, and if the paint is removed, we can see the iron. We also take our cycles for oiling monthly so that the chains in the cycle won’t get stuck or stop working, start creating weird crackle noises if they are not oiled or greased monthly.

Iron is a metal that quickly reacts with environmental conditions. Rusting of iron is a kind of redox reaction. When iron comes into contact with environmental conditions like air and water, it reacts terribly and ends up with iron rusting or corrosion.
Rusting is a specific kind of corrosion that applies to iron-containing metals. Rusting has a number of effects on iron, including:-
1. It makes them weaker by replacing the strong iron or steel with flaky power.
2. It makes them look orange and rough.
It is a serious problem because it leads to corrosion, in very dangerous and very expensive problem. Corrosion occurs if all the atoms on the same ore surface are decayed, then the full surface of metal is damaged.
Hence, to avoid rusting as well as corrosion, we need to apply paint over the iron surface. Painting removes their contact with environmental conditions.
