Abstract

The invention pertains to a method for applying a structured surface to a building surface, particularly for the interior design of a room, wherein a carrier material is provided with a surface structure and the carrier material with this surface structure is applied to the building surface.

First claim

The invention claimed is:

1. A method for applying a structured surface to a building surface, wherein a carrier material is provided with a surface structure and the carrier material with this surface structure is applied to the building surface,
wherein the surface structure is formed by a mineral graining; and the carrier material used is a dispersion and dissolvable and separates from the mineral graining under an influence of moisture.

2. The method according to claim 1 , wherein the graining is formed by rocks.

3. The method according to claim 2 , wherein the graining is formed by carbonate rocks, silicate rocks and/or silicate minerals.

4. The method according to claim 1 , wherein perlite is used for the graining.

5. The method according to claim 1 , wherein the graining comprises grain sizes from grit to gravel.

6. The method according to claim 5 , wherein the graining comprises grain sizes chosen from at least one of the grain size classes medium sand, coarse sand, fine gravel, and medium gravel.

7. The method according to claim 1 , wherein the graining is bound to the carrier material by means of a binder.

8. The method according to claim 7 , wherein the binder is a low-viscosity binder.

9. The method according to claim 7 , wherein the binder used is water-soluble and/or reversibly binding.

10. The method according to claim 1 , wherein additives, which influence the structure and/or an interconnection, are added.

11. The method according to claim 10 , wherein a compound comprising the graining and additives, which influence the structure and/or the interconnection, is used.

12. The method according to claim 1 , wherein at least one thickener is used.

13. The method according to claim 1 , wherein the carrier material is realized in a sheet.

14. The method according to claim 1 , wherein a spackle is initially applied to the building surface, and in that the carrier material with its surface structure is then applied to the spackle.

15. The method according to claim 1 , wherein the method is for the interior design of a room.

16. A covering element for covering a building surface, comprising a carrier material, to which the surface structure is applied for executing the method according to claim 1 ,
wherein the surface structure is formed by a mineral graining.

17. The covering element according to claim 16 , wherein the graining is formed by rocks.

18. The covering element according to claim 16 , wherein the graining comprises perlite.

19. The covering element according to claim 16 , wherein the graining comprises at least one grain size from grit to gravel.

20. A covering element for covering a building surface, comprising a carrier material, to which the surface structure is applied for executing the method according to claim 14 , wherein the graining is bound to the carrier material by means of a binder.

21. The covering element according to claim 20 , wherein the binder used is water-soluble and/or reversibly binding.

22. A covering element for covering a building surface, comprising a carrier material, to which the surface structure is applied for executing the method according to claim 14 , wherein the carrier material is a film.

23. A covering element for covering a building surface, comprising a carrier material, to which the surface structure is applied for executing the method according to claim 14 , wherein the carrier material is produced of a dispersible polymer powder.
