Abstract: A paint can fitted rim ring apparatus is shown comprising of a snug ring lid retaining a flexible plastic like material around the opening lip of a paint container. The painting implements such as a paint brush or a painting roller left inside the paint container may protrude outside the lip of the paint container preventing re-sealing the paint container with the lid when not in use. A flexible plastic like material can be draped over the protruding painting implements as well as covering the paint container opening. In concert with a plastic type ring when fitted snuggly around the lip of the paint container, seals the flexible plastic like material around the paint container rim, preventing the contents from drying out.

Abstract: An apparatus for applying mastic to a selected surface includes a container for mastic, a pump assembly, and a drywall tool or wand. The pump assembly is positioned in the container so that it draws mastic from the container and delivers it to the drywall tool. The mastic delivered to the drywall tool is applied to the selected surface through a nozzle in the drywall tool. The pump assembly includes a pump, a pneumatic cylinder, and a linking subassembly connecting the pump and the pneumatic cylinder. The pump assembly is operated by an air compressor. The air compressor causes a rod in the pneumatic cylinder to reciprocate. The linking subassembly translates this reciprocation to a piston in the pump assembly. The piston reciprocates within a bore of the pump assembly and draws the mastic from the container. The apparatus is mounted on a hand truck so that it may be moved to different locations.
