Protect and enhance the natural character of slate with a suitable slate sealer. Sealing slate can help reduce moisture absorption, protect against everyday staining and make the surface easier to maintain while enhancing the colour and texture of the stone.

Our range of slate tile sealers is suitable for a variety of residential and commercial applications, including slate floors, patios, paving, feature walls and other natural stone surfaces. Choose a finish based on the appearance you want to achieve and the requirements of your particular surface.

Why Seal Slate?

Slate is a naturally porous stone, so an appropriate sealer can provide an important layer of protection against moisture, dirt and everyday use. Sealing can also enhance the appearance of slate, particularly where you want to bring out the natural colours and variations within the stone.

• Helps reduce moisture absorption: Provide additional protection for porous slate surfaces.
• Helps protect against staining: Make everyday dirt and spills easier to manage on suitable sealed surfaces.
• Enhances natural colour: Some sealers deepen the colour and character of slate to create a richer appearance.
• Improves maintenance: A properly sealed surface can be easier to clean and maintain.
• Indoor and outdoor applications: Select a product suitable for the specific location and slate surface.

Choose the Right Slate Sealer

The right slate sealer depends on the type and condition of the slate, where it will be used and the final appearance you want to achieve.

Wet Look Slate Sealer

A wet look slate sealer is designed to deepen and enhance the natural colour of the stone, bringing out variations and textures that may appear more subtle when the slate is unsealed. This type of finish is popular where a richer, more enhanced appearance is desired.

Matt Slate Sealer

If you want to protect the slate while maintaining a more natural-looking appearance, a matt slate sealer may be a better choice. Matt finishes generally provide less visual enhancement than wet-look products while still providing the protection specified by the manufacturer.

Solvent-Based Slate Sealers

Solvent-based sealers are available for certain slate and natural stone applications and can provide a range of protective and decorative finishes. Always check the manufacturer's technical information to confirm compatibility with your particular slate surface.

Where Can Slate Sealers Be Used?

Depending on the product selected, slate sealers can be used across a variety of natural stone applications:

• Slate floor tiles
• Indoor slate flooring
• Outdoor slate paving
• Slate patios
• Walkways and paths
• Outdoor entertaining areas
• Feature walls
• Other suitable natural stone surfaces

Slate Sealer Application

Proper preparation and application are important when sealing natural stone. The slate should be clean, dry and free from contaminants before applying the selected product.

1. Inspect the slate: Check the surface for existing sealers, coatings, stains, damage and areas requiring attention.
2. Clean thoroughly: Remove dirt, dust, grease, efflorescence and other contaminants using a method suitable for the stone.
3. Allow the surface to dry: Ensure the slate has reached the moisture condition specified by the sealer manufacturer before application.
4. Test a small area: Apply the product to an inconspicuous section to confirm compatibility and the expected final appearance.
5. Apply the slate sealer: Apply according to the manufacturer's recommended coverage rate, application method and conditions.
6. Allow to cure: Protect the surface during curing and follow the manufacturer's instructions before allowing normal use.

Slate Sealer for Indoor & Outdoor Applications

Slate used indoors may have different requirements from slate exposed to weather, moisture and outdoor traffic. When choosing a product, consider the location, surface condition, desired finish and expected level of use.

For outdoor paving and slate areas, also consider the surrounding environment and whether additional slip-resistance requirements apply. Always confirm that the selected product is suitable for the intended application before use.
