Method of producing a stratiform material, wherein 35-45 parts by weight of solvents for polyvinylacetate (PVA) homopolymer in the form of flakes or pearls are stirred with 10-15 parts of PVA and 2-5 parts by weight of oil, while separately mixing 25-30% by weight of wood powder having a granulometry in the range of 50-150 microns and mineral fillers in an amount of 10-20% by weight, then intermixing the liquid and powdery phases to obtain a homogeneous mixture which is passed through calendering rollers, the last pair of which produces an embossing on at least one of the two surfaces, the layer being reduced to a thickness in the range of 0.2-2.0 millimeters.
