Indian Sandstone Patio Sealer Guide – Protect, Enhance & Restore

Your patio should be a place of pride — but Indian sandstone, as beautiful as it is, can quickly fall victim to the elements. Black spots, algae, grease stains, and weather damage slowly ruin its natural charm.

At Hardfloor Restoration, we’ve sealed hundreds of patios across the UK and seen the same story time and time again: beautiful stone left exposed, then left discoloured and tired-looking.

The solution?
A professional-grade Indian sandstone patio sealer that protects deeply, enhances colour, and keeps your stone looking its best — all year round.

Whether you’re a homeowner who wants to preserve that brand-new finish, or you’re restoring a weathered patio, this guide will show you:

The Science Behind Sandstone Durability

Indian sandstone is sedimentary rock composed mainly of sand-size mineral or rock grains. Most sandstone is composed of quartz or feldspar because these are the most resistant minerals to weathering processes at the Earth’s surface. Its formation process under significant pressure and temperature makes it remarkably durable but not impervious to the erosive effects of water, wind, and chemical exposure, hence the need for sealing.

Which Indian Sandstone Patio Sealer Should You Choose?

Not all sealers are created equal. Some sit on the surface. Others sink deep into the stone and provide real, lasting protection. We only recommend two — because they work. Every time.
