Product Description
FOX SILAN FR115 is a solvent-based, silane-siloxane, hydrophobic, transparent impregnation material that imparts water-repellent properties to the treated surface. Its low molecular weight ensures high penetration into the substrate; it protects the natural appearance of exterior facade coatings without forming a film layer. It can be used on low-absorption surfaces such as concrete, marble, granite, and slate, as well as on absorbent surfaces such as brick, coloured brick, aerated concrete, travertine, and tuff stone. It is resistant to alkalis, UV radiation, and freeze-thaw cycles while maintaining vapour permeability. It is also preferred for protecting historic structures against atmospheric effects.
Key Benefits
- Provides long-lasting water-repellent protection deep into the substrate thanks to deep penetration.
- Since no film layer is formed, the natural appearance and texture of the facade remain unchanged.
- Maintains vapour permeability, preventing moisture accumulation in structural elements.
- Its resistance to alkalis and UV radiation ensures sustained performance in outdoor conditions.
- Its resistance to freeze-thaw cycles allows safe application in cold climates.
- Offers effective protection on both low-absorption (concrete, marble, granite) and high-absorption (brick, aerated concrete, travertine) surfaces.
Advantages
- Provides high penetration into the substrate thanks to its low molecular weight.
- Protects exterior facade coatings without altering their appearance or forming a film layer.
- Renders the surfaces of structural elements impermeable, reducing the adverse effects of atmospheric exposure.
- Resistant to alkalis and UV radiation.
- Resistant to freeze-thaw effects.
- Vapour permeable.
Usage Areas
- On exterior facade coatings, in vertical applications
- On low-absorption surfaces such as concrete, marble, granite, and slate
- On absorbent surfaces such as brick, coloured brick, aerated concrete, travertine, and tuff stone
- For protecting historic structures against atmospheric effects
Application Steps
- 1
Surface Preparation
Before application, all dust, dirt, grease, and loose particles that could reduce adhesion must be removed from the surface. Lime, mortar, algae, fungi, and similar contaminants on the surfaces to be treated must be cleaned with FOX CLEANER BLUE FR330.

Application
FOX SILAN FR115 should be applied to dry surfaces using a suitable roller, brush, or spray machine to achieve maximum penetration on the first coat. The second coat should be applied approximately 4 hours later. On highly absorbent surfaces, one additional coat may be required. A minimum of 2 coats is recommended.
Critical
The substrate temperature during application must be between +5°C and +25°C. Application must not be carried out outside this temperature range.
Critical

Critical
The second coat should be applied approximately 4 hours after the first coat.
Critical
Application must only be carried out on dry surfaces.
Critical
Open flames near storage and application areas are dangerous. Storage and application areas must be ventilated.
Important
During application, appropriate work clothing, protective gloves, goggles, and a mask must be worn in accordance with occupational health and safety regulations.
Critical
In case of contact with skin or eyes, wash immediately with plenty of water and soap; if swallowed, seek medical attention immediately.
Important
Food and beverages must not be brought into application areas. Store out of reach of children.
Important
Store at room temperature, away from direct sunlight, between +5°C and +30°C. Shelf life is 12 months from the date of manufacture.
Important
Opened packaging must be resealed and consumed within 1 week.
Important
Store in the original unopened packaging in a cool, dry place, protected from frost.
Information
The technical values above are given at +23°C and 50% relative humidity. Higher temperatures shorten the time; lower temperatures extend it.
