Removing rust from steel i beams
Page 1 of 1
Jimbo did we not have the same question 3 months ago?
yes but l am still undecided how l should treat the steel beams after l sand off the light surface rust, the beams are not galvanized, should l paint them with cold galvanized paint, or white knight rust quard primer, or not paint them at all buy just apply fish oil over them
If not in direct contact with water (like rain) and not in a moist environment (like over water) and provided there is good air circulation and provided it is only "light" surface rust and assuming it may take a few uncomfortable hours of sanding...... then I would not bother with sanding and just coat it with a couple of generous coats of fish oil. Use spray cans or if that is too expensive buy a can and paint on with a big paint brush.
thanks, yes they are dry , thats a good idea with fish oil as sanding will be hard

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…

That just protects from further rust, l want first to apply a rust converter or rust killer to kill the rust thats there, whats the best one for galvanized steel
