The present disclosure relates to plaster boards and methods for making them. For example, one aspect of the disclosure is a plaster board comprising one or more continuous layers of material disposed within a body of hardened plaster material, the first side and second side of each continuous layer of material being substantially covered by the hardened plaster material. In certain such embodiments, each continuous layer of material includes a polymer (e.g., a damping polymer) disposed on a carrier sheet. Another aspect of the disclosure relates to a method for making a plaster board that involves drying a wet body of plaster material while a continuous layer of material or precursor therefor is disposed within it.

Disclosed herein are plaster boards that include first and second layers of hardened plaster material, a liner attached to the first layer of hardened plaster material, and a first material (e.g., a polymer material such as a viscoelastic polymer) adhered between the liner and the second layer of hardened plaster material. The liner includes one or more structurally weakened regions each extending substantially from a first edge to a second opposing edge of the plaster board. The structurally weakened regions of the liner may facilitate creation of a fissure that propagates substantially within a plane within the plaster board. Methods for making the plaster boards may involve drying wet plaster material while it is in contact with a liner having structurally weakened regions, processing a liner to form its structurally weakened regions while in contact with wet plaster material, or processing a liner to form its structurally weakened regions while in contact with hardened plaster material.

Illustrative examples of forming and using suitably adapted material in an additive manufacturing process includes operations of: exposing a first polymer sheet to a first plasma, such that an amine-functionalized sheet surface is formed; exposing a second polymer sheet to a second plasma, such that an epoxide-functionalized sheet surface is formed; and combining the amine-functionalized sheet and the epoxide-functionalized sheet, such that the amine-functionalized sheet surface contacts the epoxide-functionalized sheet surface. The workpiece is subsequently heated to form a structure, where heating of the workpiece causes covalent chemical bonds to form between the plasma-treated first polymer sheet and the plasma-treaded second polymer sheet.

Disclosed is a building board construction with increased surface strength. More specifically, increased nail pull strength is achieved via the application of an external surface coating. The surface coating is ideally applied to a paper faced gypsum building board. In one possible embodiment, the coating is formed from a water soluble polymer.

An example plasterboard includes a layer of hardened plaster material having a first surface and an opposed second surface and a layer of molded material having a surface that faces away from the layer of hardened plaster material. The surface of the layer of molded material has one or more raised features. The plasterboard also includes a liner between the first surface of the layer of hardened plaster material and the layer of molded material. Other examples include a method of forming such plasterboards and a method for installing such plasterboards.

The present disclosure relates to a method to produce a coating layer, including applying a coating composition on a surface of a carrier, curing the coating composition to a coating layer, and subsequently applying pressure to the coating layer. The disclosure further relates to a method to produce a building panel, and such a building panel, and to a method to produce a coated foil, and such a coated foil.

Self-sealing fasteners and associated building panels, systems, and methods are provided. In one aspect, a fastener includes an elongated fastener body with an external surface extending between the first end and the second end, and a coating material disposed on at least a portion the external surface. In another aspect, a fastener includes an elongated fastener body with an external surface extending between the first end and the second end, and a polymer annulus surrounding at least a portion of the external surface of the of the elongated fastener body at or adjacent the head of the fastener.
