Abstract:
1. A coating combination suitable for use in coating architectural surfaces which comprises in combination a liddable container for a coating composition, a coating composition provided within the liddable container, wherein the coating composition has a high shear viscosity at 25° C. of at least 0.01 pascal.sec and a low shear viscosity at 25° C. of from 0.05 to 3.5 pascal.sec and a plastic buoyant coating contacting member ( 4 ) having an underneath area and consisting essentially polyethylene or polypropylene member having a density of less than 1.0 Kg/L, including at least one aperture disposed substantially horizontally within the liddable container, wherein the total aperture area is 70% or less of the underneath area of the buoyant coating contacting member and has physical properties such that the buoyant coating contacting member is buoyant on the coating composition and submersible within the coating composition to the extent that under a downwards force from a coating applicator, a portion of the coating composition is allowed to flow through the at least one aperture such that the coating applicator can pick up the coating composition, in which the physical properties of the buoyant coating contacting member enables it to experience a hydraulic upthrust which is greater than the hydraulic upthrust which would be experienced by a notional planar buoyant coating contacting member made of same material when under the same downwards pressure and having the same horizontal dimensions as the buoyant coating contacting member but having an average thickness of 1 mm, so that a coating applicator can be loaded sufficiently to provide a one-coat covering when the covering is applied to a surface.
