A method of manufacturing a facade panel for the outer lining of a building in which tiling forming the outer surface of the panel is formed on the surface of the back panel meant to be the background of the facade panel. Tiling is attached to the back panel and the seams between the tiles are seamed with the help of a seam mass. A bottom panel on top of which a tile controller is set to adjust the locations of the tiles positioned upside down. The back panel is pressed on top of the tiles whereupon attachment spikes attached to the back panel penetrate the seams between the tiles. The tile seams are filled with a jagged rough mass and then filled with a hardening seam mass and attachment spikes attached to the back panel penetrate into the seam mass.
