Hygienic trays adapted to effectively restrain items under hygienic conditions are provided by equipping hygienic trays with an antipathogenic, cohesive and adhesive thermoset overlay provided in the form of an adhesive insert or tray coating. The overlay adhesively restrains emplaced items until manually removed from the overlay by the hygienic user while also providing an unexpected superior antipathogenic environment. The hygienic trays are particularly useful from hygienic applications wherein hygienic conditions and a need to stabilize trayed items against displacement are of a dominant concern. The tray may be of a simple platform design with or without a typical bordering rim which may be adapted for hand carriage or mounted onto another supportive structure.

A drywall brace and system or method for using the same can include a body including a length L, a width W, and a thickness T. The body can include a first surface defined by a first plane comprising the length L and width W, a second surface opposite the first surface, and a first end sharpened to a point adapted to form an opening through drywall. A mounting aperture can be formed completely through a central portion of the body and be sized to receive a threaded bolt for mounting a device. A first portion and second portion of flexible line can be coupled within 3 centimeters (cm) of the mounting aperture. An adhesive can be coupled to the first surface of the body and covered with a removable adhesive protective layer. A cleaning pad can be coupled to the second surface of the body.

A wall repair tool includes a cutter rotatable about a cutter axis and having a cutter body with a cutting surface. The cutter body has a central section and a pair of end sections disposed on opposite sides of the central section. The cutting surface has a first cutting texture in the central section and a second cutting texture different than the first cutting texture in the end sections.

As may be implemented in accordance with one or more aspects characterized herein, a wall patch is adhered to a wall surface having a damaged region. The wall patch has a base layer and a plurality of layers of transparent material stacked on the base layer, with the base layer being visible through the transparent material and therein aligned around the damaged region. A surface coating is applied to an area of the wall surface around the wall patch and to the wall patch, after which a top removable layer of the wall patch is removed to expose a top surface of an underlying one of the layers. A further coating is applied to the exposed top surface of the underlying layer, and to the area of the wall surface around the wall patch.

The present invention provides structure protection sheets which can not only dramatically reduce a construction period to place protective layers on surfaces of structures such as concrete but also protect structures for a long time. The present invention relates to a structure protection sheet, including: a polymer cement layer on a side facing a structure; and a resin layer on the polymer cement layer, the structure protection sheet having a thickness distribution of not more than ±100 μm.

Aspects of the disclosure are directed to apparatuses and/or methods involving stacked layers of material. As may be implemented in accordance with one or more aspects characterized herein, an apparatus includes a base layer of material with upper and lower surfaces, and stacked layers of material on the base layer. The stacked layers include a first layer stacked on the upper surface of the base layer, and further layers stacked on and adhered to one of the other stacked layers. At least one of the stacked layers has a lower surface area that is larger than a lower surface area of one of the stacked layers on which it is stacked, with an adhesive on an exposed portion thereof.

Aspects of the disclosure are directed to apparatuses and/or methods involving a wall patch. As may be implemented in accordance with one or more aspects characterized herein, a wall patch has a plurality of layers including a base layer having an upper surface and a lower surface, and stacked layers stacked over the upper surface of the base layer. Each stacked layer is stacked on one of the other layers and has an exposed lower surface region that extends laterally beyond the layer upon which it is stacked. Adhesive may operate to adhere the exposed lower surface regions and the lower surface of the base layer may be adhered to a wall surface. The stacked layers, base layer and adhesive to provide a gradient defined by the thicknesses of the layers and adhesive, and defined by the area of the exposed lower surface regions of the stacked layers.

A patch system and methods for using a patch system are described herein. The patch system has an elastomeric central portion configured to expand and contract over the types of distances commonly found in homes and other buildings that can result in opening and closing cracks in walls, for example. By applying the patch system across a crack under pre-tensioned conditions, opening and closing of the crack will not cause a visible defect in the wall or other surface.

The present invention relates to a work method for finishing an inner wall surface of a building, the method comprising the steps of: a) attaching a finishing tape to at least one of a board joint, a wall surface joint, and a wall surface crack section; b) cutting the finishing tape after attaching same by a predetermined length; c) repeating steps a) and b) for a space to be finished; and d) applying a paint to or wallpapering a building inner wall surface including a surface onto which the finishing tape is attached.

A plasterboard wall or ceiling repair assembly for repairing a hole in a plasterboard wall or ceiling panel, the assembly comprising: a sheet adapted to be deformed and passed through the hole of the plasterboard wall to be positioned for engagement with an inner or non-exposed surface of the plasterboard wall surrounding said hole; and an inflatable balloon coupled with the sheet for retaining the sheet in engagement with the inner non-exposed surface of the plasterboard wall.
