Sealing External Sandstone – Benefits, Application & Choosing the Right Sealer

Sandstone suits patios, paths, and garden features because of its natural beauty and timeless style. But sandstone absorbs moisture easily and can stain, grow algae, or suffer weather damage over time.

Applying a quality sandstone sealer helps protect its colour, prevent damage, and makes maintenance easier.

Why Seal Sandstone?

Sealing sandstone protects it by:

✔ Repelling water, oil, and dirt to avoid permanent stains
✔ Stopping moss, algae, and lichen from growing on the surface
✔ Enhancing natural colours to bring out the stone’s richness
✔ Shielding against weather damage, especially freeze-thaw effects
✔ Reducing erosion and preventing salt deposits from forming

Without sealing, sandstone can fade, stain, and wear down, especially in damp or busy areas.

Sealing keeps the stone looking natural while reducing long-term damage risks.

Is Sealing Sandstone Easy?

Yes, sealing sandstone is simple and suits DIYers and professionals alike.

• Key steps include:
• Clean and dry the sandstone fully before sealing
• Apply the sealer evenly using a roller, sprayer, or brush
• Let the surface dry and cure fully before use

Good preparation and even application ensure the best protection and finish.

Choosing the Right Sealer for Sandstone

We offer solvent-based and water-based sealers, each with benefits based on your sandstone type and needs.

Solvent-Based Sealers

• Penetrate deep for strong, lasting protection
• Work well in heavy foot traffic and harsh weather
• Boost the stone’s colour and depth

Water-Based Sealers

• More eco-friendly and safe for the environment
• May need extra coats on very porous sandstone for full protection

Sealer Finishes Available
🔹 Invisible Finish – Keeps sandstone’s natural look with full protection
🔹 Matt Finish – Low shine and subtle; less durable on solvent-based sealers due to lower resin
🔹 Satin Finish – Adds a soft sheen and strong durability
🔹 Gloss Finish – Gives a wet-look that brightens colour and lasts longest

Note: Matt finishes in solvent-based sealers wear out faster than satin or gloss.

Water-based sealers need more product on absorbent sandstone to seal properly.

Why Use a Professional-Grade Sealer?

Professional-grade sealers made for sandstone offer:

✅ Strong protection without risk of discolouration or damage
✅ Long-lasting results, especially in busy or exposed spots
✅ Easy application with a smooth, professional finish

Sealing sandstone protects it from weather, stains, and wear. Choosing the right sealer keeps your stone durable and beautiful for years.

With the right sealer and correct application, your sandstone patio or path will stay attractive, easier to clean, and well protected for a long time.
