I have about 120 sq m of sandstone paving for pathways, patio area and salt water pool surround in a beachside location.
It is a fine grained sandstone … generally light coloured with multi-coloured inclusions and suffering from mould in many areas. I plan to clean with a soap and bleach solution together with pressure hose before applying a sealer.
What sealer would you recommend?
The premium sandstone sealer seems to be the best at combating mould … so I was favouring that! Then, I was unsure if I should go for a water based or solvent based sealer. I noticed in the description of the solvent based sealer that it could slightly darken and highlight colours. I don't want a wet look …but the sandstone is colourful and some minor colour highlighting might look good … as long as the overall colour is not significantly changed.

It really depends on what level of protection you wish to achieve from your sealer. A good visual side by side comparison between our sandstone sealers can be found here:

Have you had a chance to view our pros and cons of each found here:
For sandstone due to its porosity, generally water based penetrating sealers are considered the favorite…though obviously the applicator makes the final call! A solvent in this scenario would have no additional benefit over a water based product.

Water based penetrating sealers full cure close to invisible on the majority of sandstones.
