How to Care for Your Sandstone Paving

Sandstone makes a timeless and attractive choice for patios, paths, and garden features. Its natural beauty and texture stand out in any outdoor space. Because sandstone is porous, it absorbs moisture, collects dirt, and can stain or develop algae and black spot (lichen).

To keep sandstone looking good, regular cleaning with the right products is essential. Using the wrong cleaners can cause damage, discolouration, or erosion.

Understanding Sandstone – Natural Stone Characteristics

Sandstone forms from layers of sediment and minerals, giving it a varied look and a porous structure. This porosity allows moisture to soak in, which can cause stains, algae, and biological growth, especially in damp or shady spots.

Black spot (lichen) is common on sandstone. These dark marks come from airborne fungal spores that grow deep in the stone’s pores. Removing them requires the right treatment.

Why Using the Wrong Cleaners Can Damage Sandstone

Not all cleaners suit natural stone. Many household or patio cleaners include acids, bleach, or harsh chemicals that can:

❌ Wear away the surface, causing pitting and rough texture
❌ Fade or bleach sandstone’s natural colour, making it patchy and dull
❌ Make salt deposits worse, creating white crusts that are hard to remove

Avoid vinegar, acidic cleaners, bleach-based products, or general patio cleaners. They may clean briefly but harm your sandstone over time.

Recommended Cleaning & Protection for Sandstone

Use cleaners made specifically for natural stone. These:

✔ Remove dirt, stains, and organic growth without harming the stone
✔ Are safe for regular use and keep sandstone’s look and texture
✔ Work with sandstone’s natural makeup, protecting it from damage

For grease or oil stains from barbecues or outdoor dining, use a strong degreaser made for sandstone. It lifts tough stains without hurting the surface.

For black spot (lichen), apply a specialist cleaner that targets and removes these marks without harsh scrubbing.

Sealing for Long-Term Protection

Sealing sandstone helps protect against moisture, stains, and surface wear. A good stone sealer will:

✔ Repel water, oil, and dirt to stop deep stains
✔ Prevent moss, algae, and lichen growth for cleaner surfaces
✔ Improve durability by reducing erosion and wear
✔ Keep the natural colour and texture fresh

Seal your sandstone every 12–24 months, depending on weather and foot traffic. A sealed surface cleans easier and resists biological growth better.

Why Choosing the Right Products Matters

We recommend cleaners and sealers designed for sandstone because they:

✅ Clean effectively without causing damage or colour loss
✅ Extend your sandstone’s lifespan by reducing wear and erosion
✅ Keep surfaces looking fresh, natural, and well-maintained

Many general patio or household cleaners cause more harm than good. Using purpose-made products protects your investment and avoids surface damage.

Sandstone adds beauty and value to your outdoor space. Proper care keeps it in great condition for years. By choosing the right cleaners and sealers—and treating grease stains and black spot with special products—you keep your sandstone safe and looking great.

Using the right products and methods ensures your sandstone paving stays clean, protected, and visually appealing without damage from unsuitable cleaners.
