Yes, rust will continue to grow until either moisture or oxygen has been eliminated, or the rust is fully consumed. Both moisture and oxygen are required for the rusting chemical reaction to continue, meaning that without one of these substances, the rust will stop growing. Rust has the opportunity to grow on almost any object made from iron.

Will rust keep spreading?
A common misconception is that rust is like an infection that will spread on its own. The science tells us otherwise. The metal needs to be exposed to water and oxygen, so you can have an area that is extremely rusty and an inch next to it is completely fine because the paint or coating wasn't sacrificed.
Will rust continue if kept dry?
But a well-maintained metal part (one kept clean, dry, and/or with additional protection) will not automatically rust simply because of a couple red brown rust flakes. Simply put, in order for rust to occur, there needs to be prolonged exposure to both oxygen and water (or excessive air moisture).
What happens to rust after a long time?
The Science Behind Rusting When iron is exposed to moisture or oxygen, oxidation occurs. During this chemical reaction, iron is converted into iron oxide. The iron oxide typically has a reddish, flaky appearance that becomes progressively worse over time.
Will rust Stop if you seal it?
By sealing out moisture, using a rust converter extends the life of metal and prevents future corrosion from occurring. Your new surface will be rust proof.
Will rust spread under paint?
Another big problem with rust is that even if the entire surface is well protected with paint, if rust starts to develop on the back of the metal where it cannot be seen, or in a hidden corner, or even where the paint gets scratched, this rust will continue to spread under the surrounding paint - eventually causing the ...
Should I paint over rust?
Yes, you can spray paint over rust. Before painting, take the time to properly prepare the surface to ensure that your new paint finish will last. Clean the surface. Dirt, oil and grease can affect the way paint adheres to the surface.
Will rust spread without water?
Rusting also requires the presence of moisture which, as it happens, is almost invariably also present in the air around us. Rusting, therefore, can occur without the notable presence of liquid water. It is also interesting that iron exposed to ONLY pure water will not rust.
Can rust be turned back into iron?
Using a state-of-the-art microscopy technique, experimenters at the National Institute of Standards and Technology (NIST) and their colleagues have witnessed a slow-motion, atomic-scale transformation of rust—iron oxide—back to pure iron metal, in all of its chemical steps.
How long before metal eats rust?
Like a piece of iron will corrode rapidly when it is in contact with both air and water (may take 7–8 days to show the sign of corrosion) than one piece which is in air only(may take upto 20–30 days).
Does painting over rust make it worse?
Even after you spray paint over rust, it may continue to spread and weaken the surface of your metal. The longer you wait before addressing rust development on a metal surface, the more widespread it will become and the more it will compromise the structural integrity of your metal.
Why does rust keep coming back?
Naturally, increased exposure to water and oxygen can accelerate the process, though. The more water the metal comes in contact with, the quicker it can be expected to rust. However, other factors, such as living in an area with a high concentration of salt from the ocean, can intensify the reaction.
How do you stop existing rust?
Rust Stopping CoatingsBoiled Linseed Oil (BLO) This is the old school rust stopper. ... Penetrol. Penetrol is not just for making oil-based paints flow smoothly. ... Clear Coat Spray. I've used spray polyurethane, lacquer and a few others but one of my favs right now is called Rust Coat Enamel by Do-it-Best. ... Oil-Based Paint.
Can dry metal rust?
Rust can't form without water. The reason why iron pipes often rust from the inside is that water vapor condenses on the metal. The presence of moisture speeds up the rusting process because it provides the electrolyte needed for the reaction to occur.
Can steel rust without oxygen?
Rust is a chemical reaction, so the right elements must be involved for rust to form. Rust can only occur when there are iron, oxygen and water molecules.
Does surface rust worse?
Despite your best efforts, there are times when you might still notice that rust has formed on your car, your tools, or your boat. You know that if you don't take some kind of action that it will only get worse, because once rust has formed on a surface, it not only spreads but it also becomes more concentrated.
Does rust worsen?
Rust is the product of electrochemical process that occurs when a material, such a s metal, comes into frequent contact with water. The rust continues to spread, getting worse and causing serious damage if not removed.
What Does Rust do to Plants?
If you’ve planted in iron or steel containers, it’ll only be a matter of time before they start to rust.
Can You Safely Grow Vegetables in a Rusty Container?
As you’ve seen above, there’s no harm in using rusty containers for planting.
What is the mineral that makes soil red?
Hematite is the mineral that colors soils red in some areas. However, ferric oxide is an insoluble form of iron which means that plants can’t take it up through their roots.
What is the iron in soil?
Iron occurs naturally in the soil. However, iron in the soil occurs in two forms. The form that plants can use is ferrous oxide. The other form of iron in the soil is ferric oxide like hematite. Hematite is the mineral that colors soils red in some areas.
How to protect tomatoes from rust?
So, protect tomatoes by putting something like garden fleece between them and the rusty metal.
What is rusting metal?
Rust occurs when you expose iron or steel to oxygen and moisture. You’ll soon see that familiar reddish-brown, rough or flaky material where previously there was shiny metal.
Why is the soil red?
A relatively high level of iron in the soil in some southern states is why the soil in those states is reddish in color. As mentioned above, the reddish color is from hematite. This iron oxide occurs where the soil is hot with plentiful oxygen. Other colors can appear depending on the environmental conditions.
Should You Paint Over Rust?
While you can paint over rust with any paint and a paintbrush, that doesn’t mean you should. In some cases, painting over rust might not be worth it. Sure, painting over rust can stop it, but it may be a lost cause if the rust has spread far across the metal.
How to stop rust from rusting?
Scraping off surface-level rust and using a primer can also prevent issues. Painting over rust is a great way to stop it. But you need to consider the extent of the corrosion and choose a paint that will provide enough coverage to prevent future rust. Keep reading to learn more about why metals rust and how a coat of paint can help.
What happens if you don't use primer?
If you don’t use a good type of primer and paint, the paint might chip. When it chips, the metal will come into contact with the air. Then, the potential for rust will increase.
Why use a rust primer?
Using a rust-specific primer can help add an extra layer to the metal to avoid rusting, whether you want to protect metal that’s indoors or outside.
How long does it take for primer to dry?
It also dries quickly, and it works well on metal that you use regularly. The primer dries in about 15 minutes, so you don’t have to wait forever before painting.
What happens if you don't remove rust?
If you don’t at least try to remove the rust, the paint will look uneven. While you may not be able to get all of the rust, you should remove the majority of it. Then, you can reduce the chances of the rust spreading in case you don’t fully cover it with paint.
What is the name of the substance that forms when iron mixes with oxygen?
Another name for rust is iron oxide, and it develops when iron mixes with oxygen. However, to form rust , you need to have water or moisture. Rust can also form on iron alloys, including steel.

Is linseed oil a drying oil?
Linseed (flax) oil is just an alkyd (drying/ hardening) oil. You would be better served in my opinion using the cavity wax/oil which is intended for rust prevention, rather than a drying oil which will form a skin or film where it settles out. The cavity wax some self-sealing, self-healing capability that the alkyd doesn't.
