Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A linerless pressure-sensitive label uses a heat-activated, non-tacky dead coat to cover a pressure sensitive substratum. Upon heat activation, the dead coat melts and admixes with an underlying pressure-sensitive adhesive substratum thereby resulting in an exposed pressure-sensitive adhesive. The label can then be applied to packaging or an end product by pressing the adhesive side of the label to the packaging or end product similar to a conventional pressure-sensitive label, however, no silicone-coated release liner is required. The elimination of the silicone-coated release liner results in lower material costs, lower shipping costs and less waste.
