Bluestone pavers are a popular choice for both indoor and outdoor applications due to their durability and unique aesthetic appeal. However, to maintain their beauty and longevity, proper cleaning and sealing are essential. In this guide, we will walk you through the process of cleaning and sealing bluestone pavers to ensure they stand the test of time.
Pre-Sealing Bluestone Pavers
Before diving into the cleaning and sealing process, it’s essential to determine whether pre-sealing is necessary. Pre-sealing is recommended in certain circumstances, such as:
If bluestone pavers are installed in areas prone to moisture exposure, such as shower bases or around swimming pools, pre-sealing the face and sides can provide added water resistance.
Dark Grout on Light-Colored Stone
When using dark grout with light-colored bluestone, pre-sealing can prevent the grout from staining the stone surface.
High Porosity Level
Some bluestone varieties have a high porosity level, making them more susceptible to staining. Pre-sealing can act as a protective barrier.
Various methods, such as dipping, spraying, or using a microfiber applicator, can be employed to apply Spirit NPS, our recommended pre-sealer. Ensure to follow the product instructions carefully and contact Spirit Sealers for guidance if needed.
Initial Cleaning and Grout Haze Removal
After the bluestone pavers have been laid, grouted, and washed, a grout residue or haze may be left on the surface. Here’s how to remove it:
Allow the grout to harden sufficiently for 3-4 days before attempting to remove the grout haze. During this time, protect the area from potential damage by other trades.
Typically, acid-based cleaners are used for grout haze removal, but bluestone can be sensitive to acids, leading to etching. Instead, opt for Spirit Neutral Cleaner and follow these steps:
- Sweep or vacuum 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 affected area using a broom.
- Let the solution sit for 2-3 minutes, keeping it wet by adding more cleaner if needed.
- Scrub the area using a Spirit Doodlebug with a multi-directional head for effective cleaning.
- Remove the solution with a dense mop and rinse the area with clean water.
As bluestone composition can vary based on its quarry source, test the stone’s sensitivity to acids before using any acidic product. Conduct the test on a spare piece of stone to avoid any damage.
Sealing Bluestone Pavers
Properly sealing bluestone is crucial to protect it from stains, water damage, and wear. Follow these steps for a successful sealing process:
Opt for a Breathable Penetrating Sealer
Before sealing the entire surface, always test the sealer on a spare piece of stone to ensure compatibility and desired results.
Use a Spirit Microfiber Applicator to apply the sealer evenly. Two coats are required, allowing approximately one hour between each coat.
Maintenance of Bluestone Pavers
Proper maintenance is essential to extend the life of your bluestone pavers:
- Regularly clean with Spirit Neutral Cleaner to remove dirt and grime.
- Depending on traffic and wear, periodic cleaning with Spirit HDC or Spirit Bright As may be necessary every 6-12 months.
To ensure the long-term performance of the sealer, keep these factors in mind:
- Weather conditions and harsh cleaning methods can impact the sealer’s effectiveness.
- Follow the appropriate Spirit Guide for your specific substrate to achieve optimal protection.
