This invisible water repellent is a high-performance protective treatment for porous mineral surfaces including natural stone, concrete, brick, terracotta, and masonry.
Its penetrating, non-film-forming formulation absorbs deep into the pore structure, creating a breathable barrier that repels water while preserving the surface’s natural appearance and texture.
Engineered for long-term durability, it helps reduce efflorescence, slows material ageing, protects against humidity-related damage, fungus, mold, and moss, and simplifies ongoing maintenance.

Application Details
- Apply the product to a surface that is clean, dust-free, grease-free and dry.
- Clean the surface using a suitable Winseal cleaner and allow the surface to dry completely.
- Use the product neat, do not dilute.
- Apply the coating to the surface in one coat using a roller or brush, such that once applied, it penetrates the surface and makes it wet.
- After 10 minutes, apply another layer of the coating in perpendicular direction.
- This layer helps cover the entire surface area without leaving behind any area uncoated.
- Allow the coating to dry and cure fully for a period of 48 hours before use.
For best results, apply a small test patch on your stone surface to check the end results.
