None of Caesarstone's surfaces, regardless of material, require any sealing. Materials like granite, marble and concrete are easily damaged and porous, resulting in an unhygienic worktop. With non-porous, scratch and stain-resistant surfaces from Caesarstone, you will never have to worry about hygiene issues or regular and costly sealing ever again. Caesarstone offers you the best of both worlds with manufactured porcelain and quartz surfaces that have all the benefits and versatility, without the hard work and disadvantages of natural stone worktops.
