HG voegenkleur is a unique product for colouring or herkleuren of joints between glazed wall tiles.
Make sure that the joints are clean. Remove calcium deposits from the tiles with HG professional limescale remover (hagesan blue). Rinse the grout and tiled wall thoroughly and allow the wall to dry thoroughly. Apply HG voegenkleur over with the brush supplied. Let HG voegenkleur at least 1 hour and up to 2 hours of drying. Wet the tiles with water for 5 minutes. Make the wall now clean with the included sponge.
With HG you always get a great result!
