The spraying method is developed for the fabrication of mechanically robust and self‐healing superhydrophobic coatings, which comprise highly porous and rough polyelectrolyte coatings preserved with low‐surface‐energy healing agents. These coatings can repetitively and autonomically restore superhydrophobicity in humid environments. After depletion of healing agents, superhydrophobic coatings with dual healing agents can regain their self‐healing ability by re‐spraying fluoroalkylsilane.
