A method to produce a veneered element, including providing a first layer of a first powder and applying a second layer of a second powder above the first layer. Further the method includes applying a veneer layer above the second layer. Thereafter heating and pressing the first layer, the second layer and the veneer layer together to form the veneered element and forming a bevel at least partly along at least one side portion of the veneered element, where the first layer, the second layer and the veneer layer are at least partly exposed in the bevel.

A process for producing a smooth-sided strand-based siding or wood structural panel using a pre-telegraphing process. The pre-telegraphing is performed after the primary process completes pressing and consolidation of the substrate/board. The pre-telegraphing process applies a water spray on the hot board immediately out of the primary process press, and before overlay application. The application of the water spray causes the surface of the board to swell and cure. A settling period follows to allow the top surface particles and strands to swell along with absorption and evaporation of the moisture. This is followed by surface sanding to remove the telegraphing and produce a smooth surface. This may then be followed by lamination of overlay(s). The process is completed by post-lamination treatment and coating of the board.

Sound absorbing or attenuating laminate flooring materials are provided, which are directed to be used in the production of floor covering, floor panels, furniture panels, cabinets, counter-tops and wall panels. As well, the methods for producing such products are provided. In particular, abrasion resistant panels, with a laminated structure, created by forming an assembly which consists of laminating a heat-activated resin impregnated paper wear layer, a decorative layer with printed graphics or a wood veneer decorative layer, a medium density (MDF) or high-density (HDF) natural fiber-based core and a resin impregnated paper balancing layer. To achieve sound absorbing and/or attenuating properties, any or all paper layers may be pre coated with an additional flexible elastomeric coating, film or material prior to assembly of the panel, or the natural fiber core panel may be coated with a flexible elastomeric coating, film or material prior to assembly with the papers. The flexible elastomeric coating, film or material acts to absorb, reduce, and/or ameliorate the sound transmissions inherent in laminated panels.

Methods of manufacturing a fire-retardant treated OSB to avoid press build-up issues with prior art fire retardants such as boric acid when subjected to normal heat and pressure used in forming an OSB panel. In one embodiment, the press temperature is reduced to below the melting point or softening temperature of the boric acid and/or prior art fire retardants, with a fast-cure adhesive system used in the mat to provide sufficient bonding and integrity while using a lower press temperature. Alternatively, a zinc borate or calcium borate dispersion, with melting points higher than normal press temperatures, is applied to the wood strands prior to pressing. The zinc borate and/or calcium borate are not melted or softened during the OSB manufacturing process, thereby avoiding the press build-up issues with boric acid.

The disclosure relates to a method for producing a wooden composite material board, in particular an MDF or HDF board, wherein a cake made of wood chips or wood fibres wetted with a binder is spread, which is subsequently pressed in a hot press to form a board of a desired thickness, wherein, before the pressing, a mixed powder made of colour pigments and a second binder is spread onto an upper side of the cake as a primer, wherein the cake is sprayed with water after the spreading of the mixed powder.
