How I Paint Rusty Surfaces?
The key to restoring rusty metal is to properly prep the rusty steel before you paint. A little work up front will yield long lasting results.
The first step is to clean off loose rust and flaking paint and then apply a rust-inhibitive primer. You don't need to get down to bare, shiny metal—just clean off the flakes and powdery surface rust that prevent paint from adhering. However, badly rusted metal areas need more prep work.
Start with a wire brush. Scrub partially rusted metal areas with a wire brush to remove flakes and powdery surface rust.
If the area is heavily rusted and pitted and wire brushing by hand is ineffective, use a drill with a wire wheel. Grind down heavily rusted metal spots faster with a wire wheel and a drill or angle grinder.
Once prepared, wash down all areas with Tikkurila roof cleaning agent, 1 Part Solution: 4 parts water (depending on degree of contamination) this can be applied by brush or rag. If possible power wash and rinse with clean water.
