Two weeks ago my son fixed a wooden number plaque to an exterior wall with brass screws thinking they wouldn't rust. They have and now I have horrible orange streaks down the wall where the rain has been blasting it.
Would anyone have any idea what fixings I should use please. I don't want to abandon the plaque as it was hand made and cost a fair bit.
Another option for your fixings would be to use solid stainless steel screws
Had a similar problem a few years ago when brought good quality chrome plated brass house numbers supplied with "chrome" looking screws.
These screws quickly rusted and stained the chrome numbers so got numbers replaced by shop and brought good quality stainless steel screws.
Now now more rust problems
