Once your surface is clean and dry then it would always be recommended to seal your material. If it is natural stone or stone effect paving then use either Stontex Rapid Dry for a natural matt finish or Stontex Colour Intensifier for a wet look finish. If the material in question is concrete block paving then use our Stontex Paver Plus and if its porcelain paving / tiles then use our Stontex Porcelain Protector. After treating with a sealer use the appropriate ongoing maintenance cleaner recommended.
