An apparatus including a grid having a plurality of rows and columns; a base, to which the grid is configured to be fixed; a liquid container; and a liquid application device; wherein the liquid application device is removably attached to the grid and configured to move along the grid when attached to the grid; and wherein the liquid application device is connected to the liquid container so that it receives liquid from the liquid container. The liquid application device may include a brush, a roller, and/or a spray device. The liquid may be paint or an adhesive, and for adhesive, wallpaper may be applied after the adhesive. The grid may be configured to be fixed parallel or perpendicular to the base, when the base is parallel to a floor surface, depending on whether the liquid is being applied to a vertical wall or to a ceiling.

A method of coating a fastener assembly that extends from a substrate comprises steps of at least partially saturating a permeable body with a volume of a liquid and covering the fastener assembly with the permeable body. The step of covering the fastener assembly with the permeable body comprises at least partially compressing the permeable body against the fastener assembly and transferring a portion of the volume of the liquid from the permeable body to an exposed outer surface of the fastener assembly and to a ring on the substrate, surrounding the fastener assembly.

A thin-film coating applicator assembly is disclosed for coating substrates in outdoor applications. The innovative thin-film coating applicator assembly is adapted to apply performance enhancement coatings on installed photovoltaic panels and glass windows in outdoor environments. The coating applicator is adapted to move along a solar panel or glass pane while applicator mechanisms deposit a uniform layer of liquid coating solution to the substrate's surface. The applicator assembly comprises a conveyance means disposed on a frame. Further disclosed are innovative applicator heads that comprise a deformable sponge-like core surrounded by a microporous layer. The structure, when in contact with a substrate surface, deposits a uniform layer of coating solution over a large surface.

A dispenser (10) for dispensing a flowable material M has a container (12) having an outer wall (20) and membrane (14) collectively defining a first chamber (22) configured to contain the flowable material M. The membrane (14) has a thickness and a weld seam (40) wherein the weld seam (40) has a thickness less than the thickness of the membrane (14). A fracturing mechanism (16) is operably connected to the container (12). The fracturing mechanism (16) has an extending member (64) projecting from the outer wall (20) of the container (12). The extending member (64) has a projection (66) positioned proximate the membrane (14), wherein in response to deflection of the extending member (64), the projection (66) deflects the outer wall (20) proximate the membrane (14) wherein the weld seam (40) fractures creating an opening (41) through the membrane (14) configured to allow the flowable material M to pass therethrough and from the dispenser (10).
