Deep Seal is a durable twin pack urethane sealer with extra stain resistance. Deep Seal penetrates and bonds with the tile thereby strengthening, sealing and protecting the tile from wear and tear. Deep Seal is suitable for low to medium porosity tiles (e.g. terracotta, slate, marble, granite, porcelain). Deep Seal enhances the natural colour of the tile and dries to matt/sheen finish; a gloss may be achieved by over coating with Maxi Shine
