All marble needs to be sealed with an impregnating or penetrating sealer, in order to protect the marble from staining, damage, wear and cracking. New marble floors should be cleaned and sealed straight away to avoid costly and unnecessary damage. Similarly old marble floors and surfaces should be cleaned and sealed regularly in order to maintain the life, shine and beauty of the marble. We can not stess enough, how important it is to seal your marble floors; a professional marble tiler or restorer should never leave a marble floor without sealing it properly with a professional use sealer. Marble floors left unsealed are at considerable risk of damage. If you are unsure which sealer to use, please do not hesitate to contact us on 0207 193 0143. We're here to help!
