GLEAN Patio Stain Stop Sealer works on a wide range of natural and man-made surfaces, including:
• Limestone
• Sandstone

2. Will it change the look of the surface?

4 Wipe off any excess
5 Apply a second coat for maximum protection
6 Allow to dry for at least 4 hours before exposure to moisture
6. How long does it last?
Typically provides protection for up to 3 years, depending on traffic and exposure. Reapply as needed after deep cleaning or pressure washing.
7. Can I use it indoors?
Yes. While it is designed for patios and exterior flooring, it can also be used on stone floors in kitchens, conservatories, or hallways.
8. How much area will it cover?
• 1 Litre covers 6–10m², depending on porosity
• 5 Litres covers 30–50m²
9. Does it protect against oil stains?
Yes. It effectively resists oil, grease, and general grime, making spills easier to clean before they penetrate the surface.
10. Is it suitable for polished surfaces?
Yes, though always test in an inconspicuous area first, especially on honed or highly polished stone.
