For the maintenance of your bluestone, sandstone or tiled floor, ‘t Achterhuis has various maintenance products. For the impregnation of porous floors (sandstone, old stoneware, fired tiles) we have developed the right product together with the manufacturer. ‘Superfix’ is easy to apply and easy to maintain. For the maintenance and cleaning of hard stone, we recommend using a greasy soap based on vegetable oils. Our floor soap is made in a monastery in Belgium according to a special recipe.
