Vitamin C worked - now what?

Make sure that the pool is vacuumed well after the patch because the metal dust from cutting the rebar will settle and cause metal stains if it's not vacuumed up.

Thank you James! Good to know!

I have that rust too. I will try the magnet trick, but I am certain the plaster is too thin. My PB didn’t use a nozzle for the pebble.

All metal should be buried 3" deep in the gunite.

So, even if the plaster is paper thin, the metal should not be coming through.

My gunite crew was struggling. Rebound used in many places. Mixers stacked up waiting due to clogged pump lines and connectors exploding. Arrrgh.

Thank you James, so if the rebar is buried let’s say 2”, it actually starts to poke through the gunite as well as the finish and the “larger rock” that we thought we saw has the potential to actually be a piece of rebar?

Just trying to wrap my head around this . The small magnet only sticks to that larger “rock”, no where else around it, just directly in the middle.

Keep us posted!!

Sounds just like our finish crew!

I think that it's rebar that is close to the surface for some reason.

What was the outcome of the magnet?
