When it comes to preserving the beauty and longevity of your limestone tiles, proper sealing is paramount. At Spirit Sealers, we understand the unique requirements of the stone and tile industry, and we offer a range of sealing and cleaning products specifically designed for stone surfaces. In this article, we will explore the importance of sealing limestone tiles and provide you with a comprehensive guide on the pre-sealing process, initial cleaning and grout haze removal, sealing techniques, maintenance, and re-sealing considerations.


Before sealing your limestone tiles, it is essential to prepare them adequately, especially in specific environments that pose challenges such as saltwater pools or seaside residences. In such cases, we highly recommend using our Spirit Premium Consolidator. This advanced product offers complete and total consolidation, ensuring your tiles remain resilient in harsh saltwater conditions. You can apply the consolidator through spraying, brushing, Spirit microfibre applicator, or dip sealing. For more information on stone consolidation or alternative pre-sealing options, please contact our knowledgeable team at Spirit Sealers.

Initial Cleaning and Grout Haze Removal

To achieve optimal sealing results, it is crucial to remove any grout haze without damaging the limestone surface. While acid-based cleaners are typically used for this purpose, they can etch limestone. Follow these steps to safely remove grout haze and prepare the tiles for sealing:

Allow Sufficient Time: After the stone has been laid, grouted, and washed, it is recommended to wait for 3-4 days to allow the grout to harden adequately before attempting to remove the grout haze.

Protect the Area: If other trades are still working over or near the freshly laid stone, ensure the floor and walls are adequately protected during this timeframe.

Required Materials: Gather the following items for the cleaning process: Spirit Neutral Cleaner, Spirit Doodlebug, bucket, broom, and mop.

Cleaning Process: Begin by sweeping or vacuuming the area to remove loose debris. Dilute 20 parts clean water to 1 part Spirit Neutral Cleaner in a bucket and apply it to the area that needs cleaning. Use a broom to evenly distribute the solution over the surface.

Let it Sit: Allow the solution to sit for 2-3 minutes. If it starts drying, add more cleaner to keep it wet. Clean in manageable sections.

Scrubbing: Scrub the area with a Spirit Doodlebug, a versatile scouring pad set. Attach the multi-directional head to a broom handle for easy cleaning in hard-to-reach areas.

Rinse and Remove: Remove the solution with a dense mop and rinse the area with clean water. If possible, use a wet/dry vacuum to remove dirty water effectively. Avoid using acid-based cleaners on limestone. For heavy grout haze or long-standing residue, you may use a light dilution of Spirit HDC followed by a rinse with Spirit Neutral Cleaner.


Once your limestone tiles are clean and dry, it’s time to proceed with the final sealing process. It is crucial to select a breathable penetrating sealer for optimal results. Before applying the sealer, we recommend performing a test on a spare piece of stone to ensure compatibility. At Spirit Sealers, we offer a range of sealing products suitable for limestone tiles:

Spirit Premium Seal: Our top recommendation for sealing limestone. It provides excellent protection and enhances the natural beauty of the stone.

Spirit NPS and Spirit Water-Based Premium Seal: Ideal choices when consolidation has been done using Spirit Premium Consolidator.

Spirit Colour Enhancer Pro: Enhances the natural color of the stone and can be used to bring out its vibrant hues.

Sealing Application Process

To achieve effective and long-lasting sealing results, follow these steps:

Gather the Required Materials: You will need the following items for the sealing process: A sealer of your choice, Spirit Microfibre Applicator, clean white rags, gloves, respirator, and a solvent-suitable tray (for solvent-based sealer only).

Preparation: Ensure the limestone tiles are clean and completely dry before applying the sealer. Remove any dust or debris from the surface.

First Coat Application: Apply the first coat of the sealer according to the given instructions. Use the Spirit Microfibre Applicator to evenly distribute the sealer on the tiles. Allow the sealer to penetrate the surface for the recommended time.

Waiting Period: After the first coat, wait for approximately one hour to allow the sealer to cure and penetrate the stone effectively.

Second Coat Application: Apply the second coat of the sealer in the same manner as the first coat. This additional layer enhances the protection and durability of the seal.

Excess Sealer Removal: Pay close attention to removing any excess sealer, especially when using Spirit Colour Enhancer Pro. Failure to remove excess sealer properly may result in an uneven or sticky surface.


To keep your sealed limestone tiles in optimal condition, regular maintenance is crucial. Follow these guidelines for proper maintenance:

Regular Cleaning: Clean the limestone tiles regularly using Spirit Neutral Cleaner. This specially formulated cleaner is designed to effectively clean and maintain the stone’s beauty.

Periodic Deep Cleaning: Depending on the traffic and wear, it is recommended to periodically clean the stone every 6-12 months. For deeper cleaning, you can use Spirit HDC or Spirit Bright As. Follow the instructions provided on the product label for the best results.

Re-Sealing Considerations

To ensure the long-term performance and protection of your sealed limestone tiles, proper re-sealing is essential. Consider the following factors:

Weather Conditions: Harsh weather conditions can affect the performance of the sealer. Extreme heat or cold may require more frequent re-sealing.

Cleaning Methods: Avoid using high-pressure cleaners or alkaline, acid, or solvent-based cleaners excessively. These cleaning methods can deteriorate the sealer and potentially damage the limestone substrate.

Traffic and Usage: High-traffic areas, such as commercial spaces or shower cubicles, may require more frequent re-sealing compared to domestic areas. Assess the usage and contact Spirit Sealers for expert advice on re-sealing intervals.

Proper Maintenance: Regularly clean the tiles with appropriate cleaners formulated for limestone to maintain the integrity of the sealer.

By following these guidelines and considering the factors mentioned, you can ensure the longevity and protection of your sealed limestone tiles.
