DE19513735A1 - Method of finishing real wood surface - Google Patents

Abstract

The method involves applying stain by means of an engraved structured roller in such a way that the wood grain structure of another wood type is transferred directly onto the smoothed real wood surface. The stain is applied all over onto a priming coat or onto a smoothed lacquer coat. The existing graining of the real wood surface is covered semi-transparently by a priming coat. A solvent-free water dilutable colouring stain can be used and can be transferred from the structured roller onto the wood surface by a second roller which is preferably rubberised.

Description

The invention relates to a method for finishing a real wood surface che.

For the surface finishing of real wood surfaces of all types of wood the staining or staining known for both solid wood surfaces and also used for veneered surfaces. The color or stain can mechanically by spraying or rolling or by hand can be applied with a brush, sponge or rag.

The stain colors used are semi-transparent glazing colors do not completely cover the wood surface and the wood structure more or Cover less transparently and change color.

Due to the semi-transparent paint application during pickling, the color of the Solid wood or wood veneer surface to the desired Modify the way, partially preserving the grain and pores stay. By pickling, for example, it is possible to color one to give a uniform coloring to uneven real wood surfaces hen. It is also possible to change the color tones of real wood surfaces to match different types of wood, so that for example with one a piece of furniture consisting of two different types of wood Coloring can be achieved. All of these uses are common that the surface gives a typical wood character Grain remains largely visible.

However, the pickling process has the disadvantage that solid wood or wood veneer re with poor, uneven or otherwise unfavorable growth pattern cannot be used to produce optically perfect furniture. In addition, mechanically perfect wood types enjoy, but a have expressionless growth pattern, for furniture production only a small one Appreciation.

The invention is therefore based on the object, the disadvantages mentioned to avoid the known pickling process and a finishing process  of real wood surfaces in which the wood grain structure of the Real wood surface is improved and upgraded.

This object is achieved by the method features described in claim 1 solved.

The advantage of the method according to the invention is that also Real wood with a grain of poor quality is visually appealing Wood grain structure is created.

Another advantage of the invention is that the wood utilization is improved since wood pieces with a faulty surface are also used can be and that even types of wood that due to their expressionless Grain could not be used for demanding applications Manufacture of furniture and. Like. Can be used. This is the Reduction of the necessary logging possible.

Also, if the look of certain types of wood on the market can be special is in demand, woods with such a growth pattern in large numbers be refined.

The structure pickling can either directly in the method according to the invention can be applied to the sanded wood surface or if required on a pickling primer or a sanded lacquer primer be applied. A semi-transparent primer can Partially cover the existing grain of the real wood surface.

The process can be used on solid wood surfaces or veneered wood surfaces are used, with solvent-free, water ver thinnable paints / varnishes can be used.

The method according to the invention will now be described in detail.

Woodworking essentially takes place in the following steps:

• 1. wood grinding,  
• 2. Coloring through transparent glazing stains or varnishes,
• 3. drying,
• 4. base coat-clear coat,
• 5. drying,
• 6. intermediate sanding,
• 7. Structural pickling using engraved structural rollers, indirectly via rubberized ones Roller,
• 8. Top coat clear coat.

Steps 2 and 4 are interchangeable in their sequence.

The processing essential to the invention takes place in method step 7. The stain paint is made using the structure, which is preferably made of steel roller into which the desired wood grain is engraved, indirectly via a rubberized roller applied to the wood structure to be finished. On so-called doctor knife strips the excess paint from the Structure roller, so that only color remains in the structure depressions. This gives the desired wood grain structure. The coloring is in Interaction of process steps 2 and 7 achieved. As a template for the any natural wood can be used will.
