Spills must be cleaned up with Rust Bullet Solvent immediately or Rust Bullet Concrete coatings will harden and become next to impossible to remove. Rust Bullet coatings are permanent after curing, Rust Bullet can only be removed with rigorous abrasive action with a mechanical grinder/sander. Clean up fresh, uncured Rust Bullet immediately by using Rust Bullet Solvent, following the directions on the container. If Rust Bullet gets on skin, wash with soap and water immediately. Protect any surface you do not want coated and wear protective equipment to keep yourself paint free.
NOTE: If Rust Bullet Solvent is unavailable, Xylene, Toluene, or MEK can be used as an acceptable substitute.
