Spray pack

A method for forming a uniform, stable spray coating, comprising:

• providing a spray pack comprising a spray container device and, packed therein, a spraying composition, and
• actuating said spray container device to spray said spraying composition onto a surface, thereby forming a spray coating on said surface,
• said spraying composition comprising a liquid dispersion medium and, dispersed therein, particulate cellulose having an average degree of polymerization (DP) of not more than 300 and an average particle diameter of not more than 10 μm,
• said spraying composition having a cellulose content of from 0.1 to 5.0% by weight,
• wherein said spraying composition exhibits a maximum viscosity value (ηmax) of 1×103 mPa·s or more in the viscosity-shear stress curve obtained, with respect to said composition, using a cone-plate type rotating viscometer in a shear rate region of from 1×10−3 s−1 to 1×102 s−1 and at 25° C.
