How to treat rust on bathroom wall?

[ventodimare]

Hello,

Im Renovating my bathroom.

One tiny section of the wall show a kind of rust (see photo).

I've treated the whole walls with antimould products and paints.

Can I use these products for the rust or do I need a different type of product? Thanks a mil

Hi @ventodimare 

Yes that looks like rust from a rusty iron plate under the paint.

Ideally the best fix would be to sand it back to bare shiny metal and repaint it as the rust will keep coming back if you paint over it or clean it as it is.

A short-term solution would be to clean it with a product called CLR (Calcium lime rust) this will remove the current rust there cleaned with a robust scrubbing tool from the kitchen do wear   gloves for this product as it will sting open sores.

Hello @ventodimare 

That's a good recommendation from @Jewelleryrescue. However, if the stains are too persistent it might be necessary to sand the surface to remove the rust spots on the frame. Just keep in mind that if you do sand the surface, it will necessary to repaint that section of your window frame.

If you need further assistance, please let us know.

Hi thank u both.

Just to clarify I've got this right. 

The photo shows a wall. Are u saying that underneath the cement of the wall there is a metal plate rusted?

Thanks!

Hi @ventodimare,

As per the other members, I also believe what you are looking at is a metal lintel for your window. I assume your house is brick. The metal helps support the weight of the bricks above it. It is not unusual for the metal to start to rust. I would encourage you to follow the steps above to sand back the surface. 

Please let us know if you have further questions.

Hi @ventodimare,

I also believe you are looking at a lintel and sanding and painting is your best option.

Just for clarification, have a look at How To Install a Lintel and How To Cut a Brick Wall Opening which shows a lintel being installed.

Let me know if you have any further questions.
