Product Description

FOX SILAN FR115 is a silane-siloxane based, solvent-borne, hydrophobic, transparent impregnation material that imparts water-repellent properties to the treated surface. Its low molecular weight ensures high penetration into the substrate; it preserves 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 block, 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.
  • As vapour permeability is maintained, moisture accumulation in structural elements is prevented.
  • 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 and without 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.

Application Steps

  1. 1

    Surface Preparation

    Before application, all dust, dirt, grease and loose particles that would 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.

  2. 2

    Mixing

    FOX SILAN FR115 is ready to use. It must not be mixed with any other material. WATER MUST ABSOLUTELY NOT BE ADDED.

  3. 3

    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

FOX SILAN FR115 is ready to use; it must not be mixed with any other material. WATER MUST ABSOLUTELY NOT BE ADDED.

Critical

The second coat should be applied approximately 4 hours after the first coat.

Critical

Application must be carried out on dry surfaces only.

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 containers must be resealed and consumed within 1 week.

Important

Store in the original unopened packaging in a cool, dry place, protected from frost.
