A method for coating a tile element includes providing a tile element made of a compressed fibre material having a porosity in the range of 0.92-0.99 and applying a water-based coating material to a side edge surface of the tile element extending between two opposite major surfaces of the tile element. The applying is performed by an applicator head of a continuous vacuum coating apparatus that applies the water-based coating material to the side edge surface of the tile element and removes excess through a vacuum. The water-based coating material is applied at a feeding rate of the tile element relative the applicator head in the range of 25-150 m/min. The water-based coating material forms a coating layer including an outer coating layer and an inner coating layer penetrating the side edge surface. The inner coating layer has penetration depth of at least 100 &#x3bc;m.
