Just wondering if anyone know what the rust colour stain is on my lounge walls and how do I fix it?
Many thanks in advance
Very common on rendered homes Smaller suppliers get the lower quality raw materials
THanks , l got a licensed building inspector to look at the rust, he said its just surface rust and it would take many years to become a problem because the beams are so…
if l cannot get a sandblaster would a sander with sandpaper be better then a wire brush
