1. What is GLEAN Slate Sealer used for?
GLEAN Slate Sealer is a premium water-based stone sealer designed to seal and protect slate surfaces. It penetrates deep into the stone, creating an invisible, breathable barrier that guards against water, oil, dirt, limescale, and grease, keeping your slate looking natural and protected for longer.
2. Which surfaces can I use it on?
This product is suitable for:
• All slate surfaces
• Other hard, porous surfaces such as sandstone and limestone
It is versatile, making it ideal for interior and exterior applications, including floors, walls, patios, and decorative stonework.
3. How does it protect my stone?
The water-based formulation penetrates the surface to provide a protective barrier while remaining breathable. This prevents:
• Moisture blooms or trapped dampness
• Stains caused by water, oil, or dirt
• Surface deterioration over time
4. How do I prepare the surface before applying?
1 Ensure the surface is clean, dry, and free from dirt, grease, oil, or other contaminants.
2 Avoid applying when the stone is very hot, as the sealer may evaporate before absorption.
5. How do I apply GLEAN Slate Sealer?
1 Shake well before use.
2 Apply evenly using a brush or cloth, taking care to avoid overspills. Apply sparingly for optimal absorption.
3 Allow the sealer to penetrate and dry naturally before using the surface.
6. How much coverage can I expect?
Coverage is approximately 15–20m² per litre, depending on surface porosity and application method.
7. Can it be used indoors and outdoors?
Yes. The low odour, water-based formula makes it suitable for both interior and exterior applications, from indoor slate floors to outdoor patios and walls.
8. Does it change the appearance of the stone?
No. GLEAN Slate Sealer provides a natural finish, maintaining the authentic look of the stone while enhancing its durability and resistance to stains.
9. How should I store the product?
Store in a cool, dry place. Protect from frost and ensure the container is tightly sealed when not in use.
