Professional advice and the right Lithofin products for your basalt

High

Rust stains on stone are caused by the oxidation of iron - either from iron-containing minerals within the stone itself, or from external metal objects in contact with the stone. These distinctive orange-brown stains can be extremely stubborn and require specialised treatment. Internal rust occurs when iron pyrite or other iron minerals within the stone oxidise due to moisture exposure.

Step-by-step instructions

Apply Lithofin Rust-EX undiluted onto the stain. Leave 5-15 minutes. Rinse thoroughly with plenty of water. On acid-sensitive stones: apply for shorter time (3-5 minutes) and rinse immediately. Repeat if needed.

Expert tips

  • Rust-EX contains acid - test on calcareous stones first
  • On marble/limestone, work quickly and rinse immediately
  • Internal rust (from within the stone) may recur
