Description

A method for treating a wood surface, a method for treating a wood surface, and a wood surface obtained by the method

The invention relates to a method for treating wood surface according to the preamble of claim 1.

The invention also relates to the use of a process for the manufacture of a wood product.

The invention further relates to a wooden surface, in particular a wooden door surface treated by a method.

The invention also relates to a door having a wood surface treated by the method.

The object of the invention was to eliminate two problems which occur in the prior art. The first problem relates to wooden doors, which may be exposed to moisture. Moisture penetration into the wood surface treated with a moisture barrier agent appears to be primarily due to the fact that the wood fibers of the surface can rise upward if the wood surface is first treated by a conventional sanding step surface treatment followed by a liquid water barrier film. When the wood fibers are allowed to rise, the coating surface is broken and moisture can penetrate the wood material.

The problem is particularly acute in wooden doors at the interface of two different wood materials. For example, different materials are used in the door panels of existing doors and in framing or edging, whereby moisture from the interfaces of these materials can easily penetrate under a coating, such as a ledge, and further into wooden structures. At present, it is sought to prevent moisture from penetrating into the wood material of a wood door by coating a moisture-exposed edge or frame wood with a solid coating such as laminate coating or a homogeneous film such as a paper coating impregnated with resin. Notwithstanding these steps, the doors will over time experience moisture damage due to moisture penetration from the edges of the edge masking strip (usually resin impregnated paper or paper laminate) into the frame or edge wood, particularly the lower edge wood structures, causing the strip to detach. Wood surfaces have also been treated with an anti-moisture agent so that the surface is first moistened and, after drying, the wood fibers are cut by grinding. Subsequently, the surface has been treated with a moisture absorption inhibitor. However, the result of such treatment of the wood surface is relatively uncertain and the wood fibers continue to tend to rise after treatment. The problem can be circumvented by impregnating the edge of the door, but this results, among other things, in a significant increase in the cost of manufacturing the door.

Another problem with the starting point of the invention relates to frame doors in which the door leaf is composed of one or more wood materials or in which the door leaf is a porous fiber board. The edges of the wood mirror may become rough in these and the roughness must be removed by repeated abrasive treatments.

The foregoing problems, starting from the main objective of the Applicant, was to develop a particularly fast and inexpensive treatment method for 10 wood surfaces capable of improving the properties of the wood surface so that its continuous coating with liquid surface treatment or solid coating is durable. In particular, it was an object to provide a method of treating a wood surface which provides the wood surface with such properties that after treatment it can be coated with a stable, liquid, wood surface moisture protection agent.

The process for treating wood surfaces according to the invention and the use of the method for treating wood surfaces overcome the problems which occur in the prior art.

More particularly, the invention relates to a method for treating a wood surface according to claim 1. The method comprises at least the steps of: - contacting the wood surface with the surface of a smooth surface stone material, - moving the wood surface and the surface of the stone material body relative to one another while providing a certain compression pressure P such that the wood surface is compacted but at the same time like wood fibers, - after sealing the wood surface, it is treated with a liquid or solid coating at least once.

A body made of rock material is a workpiece made of a solid stone, such as a stone of volcanic origin, for example granite, a stone of sedimentary origin, such as limestone, a stone of metamorphic origin, such as gneiss. In addition, this expression refers to pieces made from the crushed stone and binder of one or more types of rock and / or rock mineral and / or material corresponding to hard rock or rock mineral.

Wood surface means a surface containing wood fibers. The surface is, for example, a surface of a wood board, 5 solid wood or birch. The wood board may be an adhesive wood board glued from wood pieces, a fibreboard board, a glued veneer board, plywood or a particle board. The fibreboard is, for example, a porous, medium hard or hard fiber board. Medium hardboard is also called mdf and hardboard is hdf.

Coating, as used herein, refers to surface treatment with surface treatment agents such as liquid paints or varnishes, but also liquid wood preservatives that form a moisture barrier layer or film on the wood surface. Further, coating means the coating of a wood surface at the time of coating with a solid coating, such as a hotmelt adhesive, or an adhesive film coating or an adhesive film coating. The film coating often comprises a paper skeleton 15 impregnated with a thermosetting binder. Examples of such thermoplastic impregnated paper backing coatings are heat cured melamine, phenol and urea impregnated papers which are laminated on top of several layers and placed on a wooden surface. The film coating may also be formed from thermoplastic or im-20 impregnated papers with resins, such as melamine or PVC resins, which are glued with a thermoplastic onto a wood surface. Film coatings of the latter type also include veneer adhering to wood surfaces and thermoplastic film, which are also considered to be coatings here. Preferably, in this application, the coating is a liquid surface treatment agent to be applied, sprayed or rolled on a wood surface.

The process according to the invention provides the advantage that it is possible to prevent the wood fibers from rising up by the action of a liquid surface treatment agent by compacting the wood surface prior to treatment with a liquid or solid coating.

The method of sealing a fiberboard surface or wood surface according to the invention is based on pressing a sufficiently smooth stone body surface with a suitable, relatively low and uniform compression force P against the wood surface and simultaneously moving said rock material body and essentially exit the material. Since the surface pressure between the wood surface 35 and the stone body is intended to be kept low in the contact area between them 4, the contact surfaces, i.e. the surface to be sealed, and the sealing surface of the rock material body are kept parallel during sealing. In addition, the surface pressure in the contact area between the wood surface and the rock material surface is to be kept as homogeneous as possible in order to prevent the surface pressure 5 from rising even temporarily in the contact area so that the wood surface begins to release wood. In order to keep the surface pressure in the contact area between the wood surface and the rock material body low enough and homogeneous, the movement between the wood surface and the rock material surface is preferably a linear reciprocal movement. After sealing, the sealed wood surface is no longer subjected to material removal and wood fiber breaking surface treatment methods, such as grinding, but immediately after surface sealing, the surface is treated with a liquid coating, preferably a liquid surface treatment agent such as a moisture barrier. Preferably, the rock material body is stone powder, such as stone powder made of soapstone powder or calcium silicate and binder, which increases the adhesion of wood fibers to the wood base. When sealing the wood surface with such a piece of rock material, the binder that comes off the rock material during gluing is glued to the wood surface. The use of such a piece of rock material provides the additional advantage that the wood fibers remain better attached to the wood surface and do not rise up and damage the moisture barrier added to the surface. Preferably, the moisture barrier to be added is 20 acrylic paint or varnish.

In a preferred embodiment of the invention, the wood surface to be treated is a plate-like wood surface which, after compaction, is treated with a liquid surface treatment agent. In surface treatment, the plate-like wood surface is brushed / sprayed / impregnated with a moisture barrier and / or antimicrobial agent and / or a wood surface preservative and / or dye.

In a preferred embodiment, the method is preferably used to seal the outer surface of the door edge wood. Thus, for example, in a mirror door or molded door intended for a wet space door, the outer surface of the frame / edge timber can be sealed so that it can be permanently treated with an anti-moisture agent.

In yet another preferred embodiment of the invention, the method according to the invention seals the edges of the frame door mirror after making the mirror parts, such as milling. Since the wood fibers of the wood surface are not cut in the method, treatment with the liquid surface treatment agent does not lift the wood fibers upright and one treatment is sufficient to finish the mirror edges 35.

5

In another preferred embodiment of the invention, the desired portions of the wooden door are treated prior to assembly of the door by the method of the invention.

Other advantages of the invention are that the wood surface compacted by the method of the invention absorbs less liquid surface treatment agent than the uncoated surface. The compacted surface is often smoother than the wood surfaces obtained by other methods, especially if an alloyed piece of rock material is used for sealing, from which the surface smoothing stone is released during compaction. Such a compacted wood surface is easier to paint evenly than, for example, a sanded surface. In some cases, the process of the invention is also capable of polishing the surface to be sealed.

In the following, the invention and the advantages thereof will be further illustrated by way of example, with reference to the accompanying drawings.

Figures 1A, 1B and 1C, 1D and 1E show various pieces of rock material available in the invention.

Figure 2A is a side elevational view of sealing a door frame by the method of the invention.

Fig. 2B is a cross-sectional view of the door of Fig. 2A, viewed in the direction HB of Fig. 2A.

Figure 2C is a cross-sectional view of a flat door.

Figure 2D is a cross-sectional view of a frame door.

Fig. 3 is a diagrammatic top view of sealing the edge of a wooden mirror of a mirror door according to the method of the invention.

Figure 4 is a schematic side view of a method according to the invention applied to the surface treatment of a parquet board.

Figure 5 shows schematically the basic principle of the method according to the invention.

Figures 1A-1E show examples of rock material bodies. 1A and 1B are perspective views of the rock material bodies 30; The contact surface 3 32 is flat, particularly suitable for sealing planar wood surfaces, cf. 2C, for example, the straight rear edge 22 of the flat door; 22 ”surface sealing. The rock material bodies 30 shown in Figs. 1A and 1B may be solid stone bodies 32 which have been machined with a flat smooth contact surface 3 by slitting.

1C and 1D illustrate a cross-sectional view of the doped aggregate bodies 30; The contact surface 3 is staggered to fit, for example, the sealing of the exterior surface of the double-liped lip of the door, or the sealing of the exterior lip of the lip-lip (cf. Figs. 2B-2D). The doped aggregate body 30 shown in Figure 1E; 31 is formed cylindrical, whereby its contact surface 3 formed by its cylindrical shell is suitable for sealing, for example, the wear surface 5a of the parquet board 5 (cf. Fig. 4).

The rock material pieces 30 used in the invention may be formed of a single solid rock material, such as granite, or may be doped rock material, comprising one or more types of rock and / or rock material such as soapstone and granite. Also, crushed stone obtained from artificial materials corresponding to the hardness of the rock mineral is suitable for the manufacture of stone-15 pieces. Such are the many materials used in the construction industry, such as parts machined from different salts of calcium, e.g., calcium silicate bodies. The shape of the contact surface 3, i.e. the wood sealing surface, of the stone material pieces 30 corresponds to the shape of the wood surface to be sealed against which the contact surface 3 is pressed with a certain uniform force P.

Suitable rock types for use in the invention include volcanic rocks such as granite, sedimentary rocks such as limestone or rocks of metamorphic origin such as gneiss, and various rock minerals such as feldspar, which are found as such or generally bound to aggregate. For example, the blocks of stone material of Figures 1A and 1B, in which the contact surface 3 25 is flat, may be formed from a block of solid rock by splitting. Most often, the present invention utilizes aggregate aggregates of rock or mineral powder (rock crushed stone) or hard materials of the same type and binder as rock material; 31, because they can more easily obtain the desired shape of the contact surface 3 which seals the wood surface, and furthermore, if desired, the stone-30 material pieces 3 can be brought onto the wood surface to be sealed. The hardness of the rock material used in the invention is at least 1 on the Mohs scale (for example, talc, several cement-based materials for the construction industry), but more preferably at least 2-3 (e.g., soapstone, calcite rock mineral).

7

The binder is selected according to the type (s) of aggregate used in the doped aggregates and the wood surface to be compacted. The purpose of the binder is to bind the crushed stone particles sufficiently firmly together in the preparation of alloyed rock material bodies. It should also be noted here that crushed stone or powder of two or more rocks or rock minerals is often used to make alloyed rock material bodies, e.g. The binder may also be used to glue the wood fibers to the wood surface to be sealed, whereby the binder should also have adhesive properties suitable for the wood to increase the adhesion of the wood fiber to the wood. Because the properties of stone and wood are very different, e.g. with respect to its polarity, a separate adhesive suitable for the wood surface is usually used to increase the adhesion of the wood fibers to the wood surface. If the adhesive or binder is to come into contact with the wood surface to be sealed during the sealing process to bind the wood fibers to this wood surface, the stone body itself must be a relatively soft stone, such as soapstone. Suitable wood fiber adhesives include wood thermoplastic adhesives including contact adhesives such as chloroprene-based contact adhesives, polyvinyl acetate (PVAc) -based adhesives, hot-melt adhesives such as ethyl vinyl acetate copolymer (EVA), EVA (EVA), PP) based hot melt adhesives and mineral adhesives known in the manufacture of particle board. Polyvinyl acetate-based adhesives have proven to be advantageous in particular for sealing edge surfaces 22 of door 2.

The rock material of the doped aggregate body 30 is selected according to the characteristics of the surface to be compacted. It is often desirable for the wood surface to be sealed to release stone dust filling the cavities and grooves of the wood surface during the sealing process. The porous soft stone or rock mineral, such as soapstone, is then chosen as the material of the stone. For example, the surface of porous fibreboard and particle board, and to some extent semi-hard fibreboard, often remains uneven after manufacture of the board. By using a piece of soft rock / rock mineral material such as soapstone to seal the surface of the wood-based fibreboard, surface irregularities can be filled. This provides a smooth base for subsequent sealing with a liquid surface treatment agent 35.

8

The sealing contact surface 3 of the smooth surface rock material body is so smooth that said contact surface does not substantially break the wood fibers when the contact surface 3 is contacted and the contact surface 3 and the wood surface are pressed against each other at a constant contact force P and p. The maximum roughness of the contact surface 3 for a given piece of rock material depends on the hardness of the wood material to be compacted and the compression pressure used. The hardness of the wood material is influenced, among other things, by the wood type and surface method. the solid wood surface, the chipboard surface, the veneer surface, the fiberboard surface and the surface of the glued wood panel 10 all have different surface hardness depending on the type of wood processing.

Figures 2A and 2B show an embodiment of the method according to the invention. It has a molded door 2; 2a is conveyed along the conveyor track 7 from right to left. In the figure, a molded door 2; 2a and its treatment by the process of the invention are presented in a simplified manner. Door 2; 2a is treated according to the method of the invention prior to its attachment to the frame and fitting. Figure 2B shows the door 2 of Figure 2A; 2a is a cross-sectional view of the direction IIB of FIG. 2A. With form-pressed door 2; 2a is herein defined as an (interior) door having a honeycomb interior 27 having a honeycomb interior surrounded by an edge tree 20; 201. Door panels (fibreboards) 20 25 are pressed on both sides of the edge wood 201 and the kennel core 27; 25 ', 25 "to its desired shape. One currently popular type of door consists of an edge panel 20 of mdf board or glued board; 201, on which a hard disk by cold or hot pressing is disposed on each side of a door panel 25.

The door to be treated could also be a flat door 2; 2b, schematically shown in Fig. 2C or as a frame door 2; 2c, schematically shown in Fig. 2D. Figures 2C and 2D are cross-sectional views in the same direction as the cross-sectional view of the molded door of Figure 2B, i.e. the upper end of the door 2.

With frame door 2; 2c refers to a door with a load-bearing structure made of wooden, rigid frame wood 20; 203. Frame wood 203 acting as edge wood 20 is made of solid wood, glue board, laminated wood or fibreboard, such as medium hard fiber board (so-called mdf board). Frame wood 20 serving as a frame; Intermediate 203 is an interior door panel (mirror portion) 27, which is a wood panel 25 or a glass panel. The wood panel 25 forming the mirror portion 27 is solid wood, plywood, panel, hard or medium hard fiber board, or today also combinations thereof glued to each other. Figure 2D shows a solid wood frame door 2; 2c schematic cross-section.

9

Flat door 2; 2b here refers to a door having a load-bearing frame consisting of a honeycomb core 27 and a filler, and a core and a filler peripheral flap 20; 202. Edge wood 20; 202 and wood panels 25 are glued on both sides of the core 27 and the associated padding; 25 ', 25 ". Edge wood 20; 202 and the material of the wood panel 5 are often the same as that of the frame door 2; 2c.

Thus, the edge wood 20 may be the frame wood 203 of the frame door 2c, the edge wood 202 surrounding the frame of the flat door 2b, or the wood panels 25 pressed into the shape of the molded door; The edge wood 20 is made of solid wood, glulam or, at present, often fibreboard, 10 in particular a mdf fiber board. The edging can also be made of a combination of different materials, such as glued or solid wood with a fibreboard over it.

The wood panels 25 of both the frame door 2c and the flat door 2b can be further curtained with a suitable surface material such as veneer, panel, plywood or fibreboard.

2A and 2B in the molding door 2 shown in FIGS. 2a edge tree 20; 201 is a semi-hard wood fiber board (mdf board) surrounding the door 2; 2a of the cellular structures interior 27. Edge wood 20; 201 above and below are placed Door panels 25; 25 '. 25 ”which are fibreboards (hdf sheets) hot or cold pressed into shape on and under the honeycomb core 27. Edge wood 20; Each of the 20 peripheral pages 201 has a square sectional profile. Press door door panels 25; 25 ', 25' are shaped during compression of mirror portions 25a.

Adjacent to the conveyor track 7 is a plurality of soapstone crushed or so-called siporex alloyed pieces of rock material 30 on its carriage arms 61, which are supported on the longitudinal guide 25 of the conveyor track 7. 2a is a similar lip lip 20a; 20a ”and 20; 20a 'and edge wood 20; 201 on a surface 22 of a longitudinal side of the edge-facing side facing the viewer; 22 ”that on the longitudinal side 22 of the edging tree 20 turned away from the viewer; 22 '. Therefore, the edge wood 20 of the stone material pieces 30; The contact surfaces 30 coming into contact with the outer surface 22 of the 201 should be shaped into the lip lips 20a of the outer surface 22 of the edge wood; 20a ', 20a' conveniently; here, the contact surface 3 which comes into contact with the outer surface 22 of the door edge 20 of the stone body members 30 could be shaped, for example, as shown in Fig. 1D.

10

If the wooden surface 22 of the outer edge 20 of the edges 20 of the flat and frame doors of Figs. 2C and 2D were sealed, the shape of the contact surface 3 of the stone body 30 would be selected to conform to the outer surface 22. 2C in the flat door 2 shown in Figure 2C; 2b is an edge tree 20; 202 on a first longitudinal outer 5 edge 22; 22 'lip 20a, so that a piece of rock material having a contact surface 3 similar to that shown in Fig. 1D can be used to seal this edge. Instead, the flat door 2; 2b, a second outer surface 22 of the edge wood 20; 22 "is straight so that, for example, pieces of rock material 30 such as those shown in Figs. 1A and 1B having a flat contact surface 3 could be used to seal it. 10D illustrates a frame door 2; 2c in a frame tree 20; 203 on a first longitudinal outer surface 22; 22 'is a lip 20a, so that it can again be sealed with a piece of rock material having a contact surface 3 similar to that shown in Fig. 1D. A second longitudinal outer surface 22 of the frame wood 20; 22 '(the rear edge of the door 2c) has a surface profile, whereby a contact surface of a correspondingly formed alloyed stone material is used to seal it.

Fig. 2A shows a molded door 2 of rock material pieces 30; 2a, the contact surfaces 3 which are rotated in the direction 2a contact the longitudinal outer surfaces 22 of the door edge wood 20; 22 'and 22; 22 ”when door 2 is transported along the conveyor track 7 horizontally from right to left. The movement between the outer surface 22 of the edge wood 20 and the contact surface 30 of the rock material 20 is in their contact area in a linear motion. If desired, the linear movement can also be arranged to and fro by moving the support arms 61 of the rock material bodies 30 with the guides 6 back and forth while the molding door is conveyed forward along the conveyor.

The pressing pressure (surface pressure) P between the outer surface 22 of the edge wood 20 and the contact surface of the stone material bodies 30 is then arranged such that the contact surface 3 of the rock material body 30 against the outer surface 22 of the edge wood 20 seals the outer surface 22 The surface pressure on the wood surface 22 should be as homogeneous as possible in the contact area, and therefore the contact surface 3 of the rock material must be even so that no wood material is released from the wood surface 22 during sealing. The successive conveyor track 7 is longitudinally adjacent to the conveyor track by means of rock material pieces 30 which are pressed against the longitudinal outer surfaces 22 of the edge wood 20; 22 '35 and 22; The 22 "wood fibers are so strongly adhered to the outer surface of the wood that, when said wood surface is subsequently moistened with a moisture barrier fluid 11 or other liquid surface treatment agent, the wood fibers no longer rise. The outer faces (outer edges) 22 of the edges 20 are then sealed in a similar arrangement as in the figure.

Once the desired outer surfaces 22 of the edge wood 20 are sealed, they are treated with a suitable liquid-5 surface finish. If door 2; 2a, for example, would enter moist areas, treating the outer edges 22 of the edging wood 20 with, but not limited to, a suitable anti-moisture agent applied to wood-based surfaces, such as in particular its lower edge; The treatment of wood surfaces with moisture-inhibiting surface treatment agents is known in the art and other known interior surface treatment agents that prevent moisture absorption from the wood can be used. Once the moisture barrier has dried, the outer edges 22 may be further treated in a conventional manner by opacification, varnishing and / or overcoating with a suitable surface treatment agent. During the further treatment of the outer edges, the above-mentioned sealing of wood surfaces can be repeated, for example, after priming.

If conventional abrasive surface treatment procedures were used, the molded door 2; 2a on the outer surfaces 22 (outer edges) of the edging wood 20, the treatment with the liquid moisture barrier would raise the wood fibers upright, resulting in a breakage of the moisture barrier membrane or surface 20 layer and inhibiting its function as desired.

Figure 3 shows another application of the wood sealing method according to the invention. The figure schematically shows a portion of the frame door mirror 25a, which may be, for example, a porous fiber board or a solid wood board. In some door designs, the mirror base 25a2 and mirror edges 25a2 are also made of different materials and at different stages of manufacture. For example, the mirror base 25a1 may be a press plate having a cold or hot stamped mirror shape. The edge 25a2 of the mirror may be, for example, a milled pressed panel or solid wood with a milled pressed panel on it. Depending on the material and manufacturing method (e.g. milling) of the base 25a 1 of the mirror 25a 1 and its edges 25a2, for example, rough edges may remain on the edges 25a2 of the mirror 30a which must be smoothed prior to surface treatment with staining, polishing or varnishing. In Figure 3, an edge 25a2 rotating the bottom 25a1 of the mirror 25a is already connected to the bottom 25a1 of the mirror 25a, and the edge treatment is only performed at this stage. It is also possible to process the edge 25a2 or portions thereof before the edge is still attached to the mirror base 25a1.

12

By moving the rock material piece 30; 31 contact surface reciprocally along the edges of the mirror 25a2, while the edge and the rock material are pressed against each other at a relatively low, yet uniform, compression pressure to obtain the edges without breaking the wood fibers. The contact surface corresponds to the shape of the edge 25a2 of the wood mirror 25a to be shaped as a tii-5. Thereafter, said edge of the wood mirror can be further treated immediately with surface treatment agents without laborious grinding steps.

In Fig. 4, the method according to the invention is applied to the tread of the parquet board 5 coming to the board parquet before the tread is varnished and sanded. The Parket-10 dowel 5 is pushed from right to left counterclockwise with the direction of travel of the parquet board 5 in relation to the rotating cylindrical body of doped aggregate 30; 31. The contact surface 3 of the cylindrical body of stone material seals and possibly polishes the tread surface 5a of the parquet board, after which the surface of the tread surface 5a can be subjected to conventional surface treatments such as repeated lacquering and abrasion. When sealing the tread surface 5a of wood parquet by a method, it is advantageous to use a relatively soft piece of rock material for sealing, whereby any irregularities in the tread surface of the parquet can be filled with stone dust. In this way, the tread surface of the parquet board 5 is smooth, which facilitates its further treatment, such as varnishing and sanding.

Figure 5 further schematically illustrates a wood surface sealing method according to the invention. The method thus comprises selecting a suitable piece of stone material for the wood surface to be compacted from a stone crush and binder and sealing the wood fiber without breaking the wood surface by contacting the wood surface with the contact surface of the stone material body. The wood surface and the stone material body are introduced into the con-stroke with a surface pressure of P on the wood surface, thereby adhering the wood fibers to the wood base. The surface pressure is homogeneous throughout the contact area. Preferably, the contact surface of the rock material body and the surface of the wood are moved relative to one another during processing, preferably by mutual linear movement. After this sealing step, the surface is further treated with a coating. At the time of application, the coating may be a liquid surface treatment agent such as a moisture barrier, antifoaming agent, a coloring agent, an anti-adhesive primer or a lacquer. The coating may also be solid at the time of application and thereafter molten surface treatment agent such as hotmelt adhesive. The coating may also be a solid coating, both at the time of treatment and thereafter, such as an edge strip.

13

Only some embodiments of the invention have been described above, but it will be apparent to one skilled in the art that the invention may be practiced in many other ways within the scope of the inventive idea set forth in the claims.

Thus, the process of the invention can be used generally for surface treatment of wood-based products in the construction and carpentry industries.

2A above is a press door 2; 2a of the edge board 20 of the outer edges of the sealing normal mechanisms after puristeoven 2a of the door leaves 25 are pressed edge of the timber 20 and the core 27, the two sides ie. The edge board 20 of the outer surface of the seal is the last door manufacturing step before the door 2 coating, attachment of the frame and 10 of the fitting. However, it is possible to seal the outer surface 22 of the edge wood 20 before pressing the door panels 25 over and under the edge wood 20 and the interior 27.

In the exemplary embodiment shown in Figure 2, the outer surface 22 of the frame wood 20 is, after sealing, coated with a surface treatment agent. The sealing method according to the invention improves the durability of wood fibers in a wood base, especially if the rock material body 15 30 is an alloyed rock material body which contains a healing adhesive (adhesive) in the wood fiber wood base. In this case, the sealing method according to the invention can also be used for the durability of conventional beading in general for joinery products. Particularly in wood doors or window doors, various wood strips 20 are commonly used as coverings for edges 22, which include plastic strips, laminated plastic paper coatings and glued plastic impregnated paper coatings and metal strips. By sealing the surface 22 of the door edge wood 20 before it is coated with a strip, the stability of the strip in humid conditions is improved.

The wood surface can also be treated with a number of sealing steps, whereby the sealing steps 25 are generally treated with a surface treatment agent such as a primer or varnish. Here, in the first step of sealing, the wood base can be sealed using a rock material body having a coarser surface, and after the bottom treatment the wood base can be sealed with a stone material body with a smoother surface.

The above examples illustrate the treatment of a wood surface by a method according to the invention in which a piece of rock material is moved back and forth along the wood surface. It is also possible to move the stone body, for example, along a rotary path of movement on the surface of the body, provided that the compression pressure between the stone body and the wood surface 14 remains homogeneous in their contact area and does not rise too high, for example.
