This will depend on the porosity of surface. Check the surface after application to ensure full effectiveness of impregnator.

Directions for use:

1. Before application the surface must be completely clean and dry, apply generously and evenly with a low pressure sprayer, roller, natural fibre brush or sponge.
2. Apply a second application approximately 20-30 minutes after the first whilst the stone surface is still showing slightly damp inside. It will take at least 24 hours before the product 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 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.
