What Are The Main Uses of Indian Sandstone Sealer?
19th August 2026Indian sandstone is one of the most popular choices for patios, paths and driveways, prized for its warm, natural tones and unique character. But as a porous natural stone, it’s exposed to everything the British weather throws at it. That’s where Indian sandstone sealer comes in. This guide explains the main uses of Indian sandstone sealer, where you can use it and how to choose the right finish.
- Indian sandstone sealer protects natural stone from UV fading, weather, algae and stains
- It’s suitable for most natural stone, including sandstone, Yorkstone, limestone and granite
- Choose Invisible to keep the stone’s natural look, or Colour Enhancer to enrich its tones
- Both are one coat products that protect for up to 5 years
The main uses of Indian sandstone sealer
A single coat of sealer penetrates deep into the porous stone, forming a long-lasting barrier that does four main jobs:
-
Preventing UV fadingStrong sunlight can dull natural stone quickly, especially darker shades
-
WeatherproofingProtection against rain, snow and storms soaking into the stone
-
Resisting algae and lichenA barrier to moisture means green growth struggles to take hold
-
Stopping stainsOil, spilt drinks, dirt and leaking gutters can’t soak into the stone
Together, these mean far less cleaning and maintenance, and a patio that still looks fresh years after it was laid.

Before you seal
For the best results, the stone and joints must be completely clean and dry, with temperatures between 3°C and 30°C and no rain forecast for at least 8 hours. The sealer is typically ready for foot traffic in around 3 hours at 20°C and fully cured after 24 hours. Full instructions are in our application guidelines, and our guide to protecting Indian sandstone in winter covers seasonal care.

Should I choose Invisible or Colour Enhancer sealer?
Choose Invisible to keep your stone’s natural appearance, or Colour Enhancer to enrich its tones with a wet look finish.
Both are one coat sealers with the same coverage and up to 5 years of protection. Colour Enhancer is a good choice for older stone that has faded, as it brings out hidden tones and hues.
See the difference for yourself by ordering Resiblock samples, or compare Invisible and Colour Enhancer.
What stone can Indian sandstone sealer be used on?
Indian sandstone sealer can be used on most natural stone, including Indian sandstone, sandstone, Yorkstone, limestone and granite.
It isn’t suitable for pattern imprinted concrete, engineering bricks, quarry tiles, marble or slate. Porcelain paving also needs its own specialist sealer, as its dense surface behaves very differently from natural stone.

How long does Indian sandstone sealer last?
Resiblock Indian Sandstone Sealer protects natural stone for up to 5 years from a single coat.
How long it lasts depends on foot traffic and weather exposure. When it’s time to refresh, clean the stone thoroughly and apply another single coat.
Keep the surface in good condition between applications with Resiblock Algae, Mould and Lichen Remover.
How much Indian sandstone sealer do I need?
One litre of Resiblock Indian Sandstone Sealer covers around 4 to 6m², so a 5 litre container covers roughly 20 to 30m².
Coverage depends on how porous your stone is, with more porous stone absorbing more sealer. As it’s a single coat product, there’s no need to double the amount.
