Frequently Asked Questions
Our Ultimate Colour Enhancing Sealer will transform natural Sandstone** and Indian Sandstone** patios, drives and floors. To avoid trapping in moisture, the sealer is fully breathable and once applied it will leave the surface with that 'just rained on' look, bringing to life the natural rich colours within the stone or slate. The Ulimate Colour Enhancer is a 'colour intensifier' for natural stone surface where the preferred look is when the surface has been rained in and the colours are darkened.
#how2_ns The high quality unique non solvent formulation of this sealer for most** types of Sandstone means it will not only dramatically improve the look of the stone, but provide long term protection as well.

If your Natural Stone has been recently 'pointed' using a 'sweep in' pointing compound, please contact us before application on 01268 722500
If required, pre-treat the surface of the sandstone with an appropriate cleaning product, then fully clean the surface of the sandstone using a pressure washer and leave to dry thoroughly for at least 3 days. If pointed within the last 6 months using a 'sweep-in' jointing compound, the surface must be cleaned using Smartseal Residue Remover and left to fully dry prior to applying the sealer.
This is dependant on the porosity and texture of the Sandstone, but the average is 5-6m² per litre for the first coat and approx 10-15m² per litre for the second coat.
Prior to application always apply to a test area first in an inconspicuous area to determine suitability.
