What is limestone?

Limestone is a sedimentary rock formed over millions of years by the accumulation of organic remains and the deposition of calcium carbonate. These stones are mined in several parts of the world, including Australia.

Its unique composition gives limestone distinctive features and a range of visual characteristics. Limestone comes in various colours, including white, beige, grey, and blue. It often exhibits a smooth and granular texture but can also have natural veining, adding to its visual appeal.

Unsurprisingly, the use of these minerals dates back to ancient civilisations. The Parthenon, the Pyramids, and the Great Sphinx of Giza are only a few world-famous structures made from limestone.

Key features of limestone

Understanding the characteristics of limestone is essential for cleaning, protecting, and maintaining its beauty in your outdoor space.

Here are a few reasons limestone makes an excellent paving material and why you need to take precautions in cleaning and maintaining them:

1. Unique patterns: Each limestone slab or stone is unique, showcasing natural variations in colour, pattern, and texture. These contribute to the distinct beauty and individuality of limestone paving.
2. Patina: Limestone develops a naturally weathered patina, enhancing its charm and character.
3. Porosity: Porosity makes limestone surfaces susceptible to staining and discolouration. However, it can withstand outdoor conditions and maintain its elegance with proper care and maintenance.
4. Versatility: Limestone is a versatile material suitable for various applications, including paving, wall cladding, and architectural elements. Its versatility complements various architectural styles, from classic to contemporary.

Regular cleaning and sealing are great ways to keep your liquid limestone and pavers in pristine condition. But do you know how to do it properly?

How to clean outdoor limestone

While long-lasting, limestone can be damaged by harsh chemicals and abrasive cleaners. Hence, cleaning outdoor limestone requires proper techniques and the use of suitable products. Here’s a step-by-step process to effectively clean your limestone paving:

1. Remove debris: Begin by sweeping or using a leaf blower to remove loose dirt and debris from the surface of the limestone.
2. Prepare the cleaning solution: Mix a mild detergent or specialised stone cleaner with water according to the manufacturer’s instructions. Use a pH-neutral cleaner specifically formulated for limestone.
3. Apply the cleaning solution: Apply the cleaning solution to the limestone surface, focusing on stained or dirty areas. Allow the cleaning solution to stay on the surface for a few minutes to break down stubborn stains and dirt before scrubbing.
4. Scrub gently: Avoid vigorous scrubbing and use a soft-bristle brush or a mop. Clean the surface with a circular motion to avoid streaking.
5. Rinse thoroughly: Rinse the limestone paving thoroughly with clean water, ensuring all traces of the cleaning solution or any residue are removed. You may need a pressure washer to remove dirt from heavily soiled surfaces. However, use the lowest setting possible to avoid damaging the stone.
6. Dry the surface: Use a clean absorbent towel or allow the limestone to air dry completely.

Besides keeping it tidy, property owners must take care of their limestone paving to preserve its appearance and structural integrity.

How do you care for outdoor limestone?

Being armed with essential information on the stone’s main characteristics gives you an idea of how to prevent staining, scratches, and cracks on your limestone surfaces. Take heed of the following tips:

1. Clean your limestone paving regularly: Sweep or use a leaf blower to remove loose dirt, leaves, and debris. Avoid damaging the surface with harsh chemicals or abrasive cleaners. Opt for a pH-neutral cleaner specifically formulated for limestone.
2. Avoid stains and spills: Limestone is porous and can absorb fluids, making it susceptible to stains. Promptly clean up spills such as oil, grease, or acidic substances. Gently scrub the affected area if necessary. Rinse thoroughly with water and dry the surface with a soft cloth.
3. Protect from heavy objects: Limestone pavers are softer than other minerals, like marble, for instance. Hence, they may crack if you place heavy objects on the limestone paving. As much as possible, avoid doing this. Moreover, use protective mats under outdoor furniture or planters to distribute the weight evenly.
4. Safeguard against scratches: Keep sharp objects away and avoid dragging heavy items across the surface. Place rugs over your limestone flooring in high-traffic areas to minimise the risk of scratches.

Caring for limestone pavers includes seeking professional assistance for repairs or restoration when necessary.

How do you maintain limestone paving?

In addition to regular care, certain practices will help keep your exterior surfaces in optimal condition. Consider the following limestone paving maintenance techniques:

1. Limestone sealing: Applying a high-quality sealer to your outdoor limestone paving can enhance durability and protect against stains and weathering. Consult a professional for the appropriate sealant and follow the manufacturer’s instructions before applying.
2. Deep cleaning: Deep cleaning is recommended to remove and prevent stubborn stains from accumulating. Consider using a pressure washer with a gentle spray setting to remove embedded dirt or grime from the surface. Also, regularly remove weeds or moss that may grow between the paving stones, which can cause damage and discolouration over time.
3. Removing efflorescence: Efflorescence appears as a white powdery substance on the surface of the limestone. Proper removal requires mixing equal parts of white vinegar and water and applying the solution to the affected area. After letting it sit, gently scrub the surface with a soft brush and rinse thoroughly. Repeat if necessary.
4. Repairing cracks and damage: Regularly inspect your limestone paving for cracks, chips, or other damage. Address issues promptly to prevent further deterioration. Contact a professional stone restoration company to assess and repair the damage without damaging the limestone.

How do you protect limestone paving?

Protecting your limestone paving and prolonging its lifespan requires three elements:

1. Regular maintenance: Follow a regular maintenance routine, including cleaning, sealing, and periodic deep cleaning, to protect your limestone from stains, weathering, and damage. If exposed to heavy traffic or weather, you should seal limestone paving once a year or more often.
2. Use proper cleaning products: Only use cleaning products specifically formulated for limestone. Avoid acidic or abrasive cleaners that can erode the surface.
3. Maintain the surrounding landscape: Ensure plants or trees do not overhang onto the limestone paving and deposit debris or excess moisture.
