Abstract (en)
This invention relates to a method of treating a surface with reagents. The method comprises: (i) establishing a reagent in a liquid phase; (ii) forming a foam of said liquid phase; (iii) applying said foam to said surface to be treated; (iv) causing or allowing the foam to collapse at the interface of said surface being treated to deposit the reagent thereon and thereafter removing or deactivating the reagent on said surface when the treatment is complete, whereby the rate of foam collapse is controlled to control the rate of application of the reagent to the said surface.
