Method and aqueous composition for preventing wildfire

A method for preventing wildfire at a target by enhancing adhesion of a fire retardant to the target, the method comprising:

• providing sprayable aqueous composition;
• and
• applying the aqueous composition to the target by spraying;
• wherein the aqueous composition comprises:
• a fire retardant;
• and
• a dispersion of fibrillar cellulose obtained through a fibrillation process of plant cellulose fibers, wherein the fibrillar cellulose has an average diameter of fibrils or fibril bundles of 2 μm or less, wherein the fibrillar cellulose has an average length of fibrils or fibril bundles of from 1 to 100 micrometers;
• wherein the aqueous composition comprises the fibrillar cellulose in a range of 0.1-2% (w/w);
• wherein the aqueous composition either:
• does not include a surfactant;
• or
• further comprises a surfactant in an amount of 0.1-0.5% (w/w);
• wherein the target is an outside nature area;
• and
• wherein the aqueous composition enhances adhesion of the fire retardant to the target.
