Rusting Rebar

[tiride]

I have two spots in my pool both in the bottom corners that appear to be rust from rebar. Both spots are 1cm or less. When I first saw them I swam down and hit the spots with a brush and I got a small reddish orange cloud in the water. Being that the spots are so small are there underwater patch kits to repair the spots? The spots are so small only I notice them because I know the pool so well. I'd hate to have to go through extensive repairs for such small spots and hoping there is a cheeper and simple solution. Thanks!

Plaster patch will cover the stains.
If it’s rebar erosion, the exposed steel needs to be sealed or the staining will continue, rust-oleum paint can be used to achieve this.

The rust stains will weep through any plaster over those areas.

The permanent fix is to drain the pool, expose the rusting rebar and cut it out, patch the hole with hydraulic cement and then plaster.

If you dig down to expose the rusting rebar you can paint it with rust-oleum or cut it out. I prefer removing the rebar so there is no possibility of the rust reoccurring.
