Method For Treating Wood

Abstract

A method for treating a main surface of a plank including applying a system of grooves or scratches in the surface; and applying a protective agent or filling agent into the grooves. The grooves are applied by applying saw cuts into the main surface using a rather coarse saw, for instance a circular saw, a band saw or a chain saw.

1 . Method for treating a main surface of a wooden plank comprising:
 arranging a system of grooves in the surface; and   applying an agent, being a protection agent or filling agent, into the grooves.   
     
     
         2 . Method according to  claim 1 , wherein the grooves are applied parallel to the longitudinal direction of the plank. 
     
     
         3 . Method according to  claim 1 , wherein the grooves have a depth larger than approximately 0.05 mm. 
     
     
         4 . Method according to  claim 1 , wherein the grooves have a width in the range of approximately 0.5 mm to approximately 5 mm. 
     
     
         5 . Method according to  claim 1 , wherein the grooves are applied by making saw cuts in the main surface using a relatively coarse saw, for instance a circular saw, a band saw or a chain saw. 
     
     
         6 . Method according to  claim 1 , wherein the grooves are applied by selectively sanding of the upper face, such that the softer parts of the wood are removed to a stronger extent than harder parts. 
     
     
         7 . Method according to  claim 1 , wherein applying is done by spraying. 
     
     
         8 . Method according to  claim 1 , wherein the treated surface is finished by rubbing with a cloth. 
     
     
         9 . Method according to  claim 1 , wherein the protective agent comprises one or more of oil, wax, and varnish. 
     
     
         10 . Method according to  claim 1 , wherein the protective agent comprises acryl and/or polyurethane. 
     
     
         11 . Method according to  claim 1 , wherein the protective agent comprises pigment substances. 
     
     
         12 . Method according to  claim 1 , wherein the protective agent comprises one or more components, metal, silicium, lime, and a chemical compound of the components. 
     
     
         13 . Plank comprising a main surface with arranged therein a system of grooves, wherein the grooves contain an agent, being a protective agent or filling agent. 
     
     
         14 . Plank according to  claim 13 , manufactured with the method according to  claim 1 . 
     
     
         15 . Method according to  claim 1 , wherein the grooves are applied perpendicular to the longitudinal direction of the plank. 
     
     
         16 . Method according to  claim 1 , wherein grooves are applied both parallel to the longitudinal direction of the plank and perpendicular to the longitudinal direction of the plank. 
     
     
         17 . Method according to  claim 3 , wherein the grooves have a depth in the range of approximately 0.1 mm to approximately 5 mm. 
     
     
         18 . Method according to  claim 4 , wherein the grooves have a width in the range of approximately 1 to approximately 2 mm. 
     
     
         19 . Method according to  claim 1 , wherein the grooves are applied by selectively burning, and then selectively sanding of the upper face, such that the softer parts of the wood are removed to a stronger extent than harder parts. 
     
     
         20 . Method according to  claim 1 , wherein applying is done by using a brush.
