Mattstone H₂O Impregnating Sealer is a water-based, breathable sealer ideal for natural stone, porcelain, terracotta, slate, travertine, and quarry tiles. It penetrates deep into the substrate to provide invisible, long-lasting protection against water, oil, and grease stains—without altering the natural matt finish or coloration of the surface.
Suitable for both internal and external use, this sealer is perfect for a variety of applications: kitchen and bathroom floors, patios, utility spaces, feature walls, and even decorative stonework. The breathable formula ensures moisture vapor can escape, helping to prevent damage from trapped moisture and maintaining the substrate’s integrity.
Coverage is excellent, with approximately 35–40 m² per litre, making it ideal for small touch-ups or larger trade projects. Application is simple: clean and dry the surface, apply evenly, let it absorb, and lightly buff off any excess after around 60 minutes. Cleanup requires only water.
