Sandstone Cleaning and Sealing

We service Sydney, Newcastle, Central Coast, Port Stephens and the greater Hunter regions.

Sandstone is relatively soft, making it easy to carve and has been widely used around the world in constructing temples, homes, and other buildings for thousands of years. It has also been used for artistic purposes to create ornamental fountains and statues. More common uses today are pillars, retaining walls, facades, outdoor paving and pool surrounds.

Because of its porous nature, sandstone is prone to mould and grout haze if not pre-sealed prior to grouting.

High pressure water is never recommended to clean sandstone as it is very easy to create divots and indentations in the stone.

Sealing your sandstone creates a barrier that provides protection against stains by chemicals, contamination and deterioration.

If you have a salt water pool with sandstone surrounds it is imperative that you seal with an impregnating sealer with hardening properties that will help solidify the particles in the stone and stop any chance of salt spalling and disintegration of your stone.

If you are wondering if it may be time to re-seal then you can easily test how porous your sandstone is by placing about 15-20mls or a tablespoon of water on the treated surface and leave for 20 minutes.

Then soak up the water with some paper towel or a tissue, pressing hard to soak up any water in the pores of the surface. If the water has absorbed into or leaves a dark mark on the surface, it requires more sealing.
