A process and apparatus for the application of aqueous paints. The paint is supplied in a flexible container compressible by an adjacent inflatable bag. Paint travels from the container via a long delivery tube to a brush, roller or pad applicator. The container is compressed horizontally by means of a foldable base when compressed by the inflatable bag. The length of the tube is 1 to 3 m, and the inner diameter of the tube is 5 to 15 mm, to provide a steady delivery of paint to the applicator.

[ We claim:] [1.] A process for the roller-application of an aqueous coating composition to a surface at ambient temperatures wherein the process includes(a) supplying the coating composition in a flexible container (4) having an outlet (9),(b) horizontally compressing the container by means of air pressure to expel the coating composition from the container via the outlet,(c) transferring the expelled composition via a delivers tube (10) which is 1 to 3 m long onto a roller (3)) andd) transferring the composition from the roller onto the surface characterised in that the coating composition is thixotropic and the process also includese) biasing the container to be compressible in a horizontal direction during use by the provision, for the container, of opposed flexible walls (5) spaced apart by a flexible transverse base (6) having a flexible crease (7) which extends between the walls across the width of the container,f) using an air-pressure of from 1.8 to 2.3 bar absolute to inflate a flexible bag (43) and urge it horizontally against one of the opposed walls of the container to cause the compression which expels the coating composition andg) subjecting the coating composition to the effects of passage through the 1 to 3 m long delivery tube of internal diameter 5 to 15 mm.
