A caulking assisting device has of a fixed frame mounted to a filler coating-supplying device, a rolling part mounted to the fixed frame, a movable frame and an elastic element. The positioning frame has a pair of first limiting recesses and a pair of second limiting recesses. The movable frame is pivoted to the fixed frame and is rotatable, and a tapered roller is pivoted at the end of the movable frame. Meanwhile, the elastic element is disposed on the movable frame, while a positioning protrusion is located at both ends respectively. As a result, the tapered roller can be moved to a use position and a non-use position by the rotation of the movable frame, thereby switching between the rolling part and the tapered roller while in use.

A set of molded silicone rubber devices is used for cleaning a variety of paint brushes in a variety of containers. A circular basic paint puck is molded silicone rubber with paint-cleaning teeth and a diameter matching the bottom of a standard coffee cup or else a standard disposable paint mixing cup of 8 oz, 16 oz, 32 oz or 64 oz. A bucket puck has a diameter fitting a 1-gallon or 5-gallon paint bucket and is suitable for large, heavy brushes. An expansible paint puck doubles in size when submerged in turpenoid paint solvent and has a silicone rubber purity and hardness ensuring uniform expansion and contraction. A paint puck set includes solvent container, stable footing and ultimate rinse cup topper with brush holders, flexible cup grip, brush scraping surfaces and drip tray.

The invention discloses an adjusting device capable of automatically reconciling a paint to detect a color effect, comprising a base, a support, a top body and an auxiliary body. The support body and the auxiliary body are fixed on the top surface of the base. A support body is located on the left side of the auxiliary body, and the top body is fixed on the top surface of the auxiliary body. The support body is provided with two upwardly-opening storage chambers, and the two storage chambers can be stored in For paints of different colors, the top surface of the base can be placed with a reconciliation barrel. The reconciliation barrel is provided with a reconciliation cavity with an upward opening, and a connection cavity is provided on the lower side of the storage cavity. It can be more stable and uniform, and can prevent the paint from drying out and wasting. It can also continuously detect the color during the blending process, which can make the color of the paint more accurate.

A flexible painter's string with pressure sensitive adhesive is provided. The painter's string provides edging for non-linear surfaces and provides a three-dimensional painting guide.

The novel cavitation based cleaning devices preferably contain one or more cavitation creating elements and a reservoir holding the cavitation creating elements with an opening for introduction of an item in proximity to the cavitation creating elements. The reservoir may be or include a water filled reservoir. Collapse of bubbles created by the cavitation creating elements preferably pulls debris from the item. In some aspects, the reservoir is configured to permit introduction of an item comprising a paint brush. The debris may include wet, semi-dry, and/or dry paint on and/or inside the paint brush. The cavitation creating elements may include cylinders that spin in opposite directions within the reservoir. Cavitation is preferably created without using transonic methods or elements. Aspects of the invention also include methods performed by and/or using the novel cavitation based cleaning devices disclosed herein.

A stencil for use in stenciling complex symbols incorporates a stencil substrate employing a flexible material, having a plurality of symbols arranged thereon. A plurality of folding stiffeners are incorporated in the substrate, each stiffener being positioned to split symbols having stencil cutouts forming isolated elements within an interior of the symbol. The stiffeners are foldable about a vertex, to collapse into a raised position and bring together the split symbol, with the stiffeners supporting the isolated elements created by the cutouts and portions of the stencil cutouts forming the symbols that extend into coincident channels in the folding stiffeners, to bridge adjoining portions of said split characters.

Provided is a tool that includes a handle assembly including a top portion and a bottom portion. The tool also includes a lock plate disposed between the top and bottom portions and having a deflectable arm having a free end biased towards the top portion, a fixed end opposite the free end, an inner edge, an outer edge, and a detent near the free end and the inner edge. The tool additionally includes a blade having first and second ends, an indent in a bottom surface of the blade near the first end for engaging the detent in a closed position, and a ramp on the bottom surface near the indent defining a reduced thickness portion of the blade that reduces in thickness from the indent towards an edge of the blade to reduce contact between the detent and the blade during rotation of the blade.

Expert system and method for computing an application procedure for painting vinyl panels a target color at a paint application site while preventing vinyl warping. A target reflectivity indicator is computed for the vinyl panels once painted. When the target color and target reflectivity indicator are met by application of the multiple paint layers, the application procedure computed identifies a pigmentable waterborne paint composition, one or more proportioned paint pigments to achieve the target color at a predictable transmissivity and a preparatory waterborne paint composition considering a corresponding predictable reflectivity. Applying the pigmentable waterborne paint composition, once pigmented with the one or more proportioned paint pigments, over the preparatory waterborne paint composition meets the target reflectivity indicator for the vinyl panels at the target color. Instructions are then sent to a remote device comprising the application procedure for painting the vinyl panels at the target color while preventing vinyl warping.

A paint brush cleaning nozzle that includes: a hose coupling whereas the house coupling is adapted for connection to a hose; waterflow tubing extending from the hose coupling; a plurality of teeth extending from the waterflow coupling; and a hole in each tooth of the plurality of teeth allowing for the flow of fluid through the nozzle. The paint brush cleaning nozzle may also include a control valve where the control valve controls the flow of fluid through the plurality of teeth and an o-ring within the coupling.
