Title (EN) PARQUET STRUCTURE AND METHOD FOR ITS MANUFACTURING
(FR) STRUCTURE DE PARQUET ET PROCEDE DE FABRICATION
Abstract:
(EN) The invention relates to a parquet structure and a method for its manufacturing. A parquet surface layer (1) is made of wood blocks, wherein the direction of wood grains is perpendicular or at an acute angle relative to the level of parquet surface. Prior to the lacquer finishing, the surface of an otherwise finished wood parquet is coated by applying a filling resin or varnish (2) which impregnates into the interstices of and inside the vertical wood grains to the depth of appr. 0.2 - 0.5 mm. The filling resin or varnish is used in the amount of 100 - 300 g/m2. After setting, it is coated by applying several layers of parquet lacquer in a total amount of 20 - 50 g/m2. The employed filling resin can be inexpensive polyester resin and the finishing lacquer can be conventional urethane lacquer.
(FR) L'invention se rapporte à une structure de parquet et à son procédé de fabrication. On constitue une couche de surface de parquet (1) avec des blocs de bois, dans laquelle le sens des veines du bois est perpendiculaire ou à angle aigu par rapport au niveau de la surface du parquet. Avant d'effectuer la finition à la laque, on revêt la surface du parquet en bois terminé, d'une application de résine ou de vernis d'apprêt (2), imprégnant les interstices et les veines du bois verticales, jusqu'à une profondeur située entre 0,2 et 0,5 mm environ. On utilise la résine ou le vernis d'apprêt selon une quantité de 100-300 g/m2. Après durcissement, on passe plusieurs couches de laque de parquet selon une quantité totale de 20-50 g/m2. La résine d'apprêt utilisée peut être une résine polyester économique et la laque de finition, une laque uréthane traditionnelle.
