Hi,

We have a shed which is rusted at the bottom as shown in attached pic.

Due to which water gets inside shed when there is rain.

please suggest if there is any solution to fix the rusted metal so water doesn’t get in.

Appreciate your Help.

Thanks

Hi @approachmhn 

Nothing short of  replacing the sheets will fix the rust.

But if if you dig away out side soil away from the shed   make a  small ditch

Use  some plastic sheeting (Like shown  below)  from inside the shed  along the bottom sticking out the bottom outside from under the metal sheeting and bury the plastic edge in the little  trench it will  repel water  for many years to come. and wont cost you much money  now to fix one day the metal sheets will become to rusty to patch.  If the plastic inside sags  simply spot liquid nails it  to the shed  wall.

 Hope this helps

Hi @approachmhn,

It's great to see that @Jewelleryrescue has been assisting.

The first step is to pull the soil back from the sheeting and inspect the edge. Having the soil piled up against the shed has caused a moist environment and accelerated the rusting process. Once you pull back the soil and take a closer look at the panel's bottom edge, we'll be able to assess whether water is gaining access to the inside under the sheets or if the sheets themselves have holes in them. 

For the moment, I'd apply rust converter to the areas and then spray over them with Dy-Mark 400g MetalPro Zinc Gal. Check the bottom edge of the sheets and view this helpful guide: How to waterproof a shed floor.

As @Jewelleryrescue mentioned, if the sheets have rusted away entirely at the bottom, then there are limited options to resolve the issue.

Please let us know if you have any questions.

Hi @Jewelleryrescue @MitchellMc ,

it’s been long time I asked for solution but could not do this due to other water issues around the house.

today I started digging and found the sheet is only rusted. No holes in the sheet.

so, if I apply rust converter and then paint with gripset betta bitumen, then insert plastic from inside as suggested and put back soil. Will that work.

Appreciate your advice.

Hi @approachmhn,

That sounds like a solid approach and should help address both the rusting and potential water issues around the base of the shed. Using a rust converter is a great idea, as it will stabilise the existing rust and help prevent it from spreading. Just make sure you give the affected area a thorough brush down first with a steel-bristled brush to remove any loose or flaky rust, and give it a light sand where needed to smooth the surface before applying the converter. 

Once that’s done and the surface is dry, coating it with Gripset Betta Bitumen is a good next step — it will create a waterproof barrier to stop further moisture from sitting against the sheet. Adding plastic on the inside will offer an extra layer of protection, especially before putting the soil back, and will help direct water away from the shed wall. Provided there are no holes in the metal, this approach should hold up well and significantly extend the life of the shed.

Thanks @MitchellMc.

i just noticed that there are 2 small hole of 1-2 mm size in wheel barrow with a little bit of rust around it.

Please suggest a solution to cover the hole.

Hi @approachmhn,

You can fill the holes with a metal epoxy and then sand the surface to a smooth finish before painting.
