  1. Before application make sure the surface is completely dry, clean and free from debris.
  2. Apply Ultimate Natural Stone Sealer generously and evenly with a low pressure sprayer, paint pad, natural fibre brush or sponge (we do not recommend using a roller). Remove any excess sealer with dry cloth after 20-30 minutes.
  3. Apply a second application of Ultimate Natural Stone Sealer approximately 45-60 minutes repeating the process. It will take at least 24 hours before the Natural Stone Sealer will offer full protection. Until this has happened, keep the surface free from water and oil spills, as stains may occur before fully cured.

Please Note:

Areas not to be sealed with the Ultimate Natural Stone Sealer must be protected with masking materials. It is strongly recommended when using coloured grouts that a stain test is completed before proceeding.


Clean treated areas with Universeal Easy Clean, do not use harsh or abrasive cleaning agents as this can have a negative effect on the treated surface.


Up to 30m2 per litre per coat.
This will depend on the porosity of surface. Check the surface after application to ensure full effectiveness of impregnator.
