NanoGuard SI Invisible Water Repellent
In StockSolvent-based silane/siloxane nano treatment that penetrates masonry and concrete to form an invisible, breathable water-repellent shield.
NanoGuard SI soaks into mineral surfaces and lines their pores with a water-repellent nano layer, dramatically cutting water uptake while leaving the look of the surface untouched.
Because it remains vapour-permeable, walls can still breathe — helping to reduce dampness, salt damage and efflorescence over the long term.
Key Features
- Invisible finish — no change to surface appearance
- Deep nano penetration into the substrate
- Breathable: blocks liquid water, lets vapour escape
- Reduces water absorption, salts and efflorescence
Applications
- Exposed brick, stone and concrete façades
- Protecting plaster and natural stone
- Reducing dampness in external walls
- Heritage and architectural surfaces
