  • Patent number: 7900313
    Abstract: A coating combination suitable for use in coating architectural surfaces which comprises in combination a lidable container, a coating composition provided within the lidable container, and a buoyant coating contacting member (4) including at least one aperture disposed substantially horizontally within the lidable container. The buoyant coating contacting member has physical properties selected from at least one of shape, density, number of apertures, and total area of apertures 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. When the combination has a lid, the lid is removed for insertion of the applicator for the exertion of downward pressure.
