Funcosil SNW 30 Liter – Professional High-Performance Facade Water Repellent

The Funcosil SNW 30 liter is a premium, water-based facade impregnation solution made with silane/siloxane technology. This colorless protective treatment penetrates deeply into porous surfaces, making them permanently water-repellent while maintaining breathability. Its large 30-liter packaging makes it ideal for medium to large facade projects, offering efficiency and long-lasting protection.

Active ingredient content: 10%

Key Benefits

• Protection against driving rain
• Reduces dirt and algae growth
• Breathable and vapor-permeable
• Deep penetration with long-lasting effects
• Improves frost and de-icing salt resistance
• UV- and alkali-resistant
• Solvent-free, odorless, PFAS-free
• Helps reduce energy loss

Applications

Funcosil SNW is suitable for porous, mineral substrates, including:

• Brick
• Sand-lime brick (KS brick)
• Mineral plaster
• Aerated concrete
• Natural stone
• Mineral-based insulated facade systems (ETICS/WDVS)

It is also perfect for renovation, maintenance, and restoring existing hydrophobic layers.

Coverage per Substrate

The required amount depends on the porosity and absorption of the surface. Approximate coverage:

• Fine-pored brick: 0.8 L/m² (≈37 m² per 30 L)
• Coarse-pored brick: 1.2 L/m² (≈25 m² per 30 L)
• Smooth sand-lime brick: 0.7 L/m² (≈43 m² per 30 L)
• Rough sand-lime brick: 0.8 L/m² (≈37 m² per 30 L)
• Aerated concrete: 1.0 L/m² (≈30 m² per 30 L)
• Fine-pored natural stone: 0.8 L/m² (≈37 m² per 30 L)
• Coarse-pored natural stone: 1.7 L/m² (≈18 m² per 30 L)

Average yield is approximately 25–40 m² per 30 liters. For precise results, test a small area of 1–2 m² first.

How It Works

Funcosil SNW penetrates deeply into surface pores and creates a hydrophobic barrier. Rainwater is repelled while allowing water vapor to escape, preventing moisture problems, dirt accumulation, and frost damage. This extends the life and appearance of your facade.

Application Instructions

• Apply by flooding (low-pressure; do not spray)
• Work from top to bottom
• Apply multiple wet-on-wet layers
• Finish with a block brush
• Ideal application temperature: +10°C to +25°C

The surface must be clean, dry, and structurally sound. Repair cracks or defects beforehand.

Storage & Shelf Life

• Minimum shelf life: 12 months
• Store in a cool, dry, frost-free environment
• Use opened containers promptly

Important Notes

• Not suitable for polystyrene or bitumen
• Protect treated surfaces from weather during application
• Always test on a small sample area first
• For salt-containing substrates, conduct prior analysis

Summary

Funcosil SNW 30 liter is a professional, durable solution for water-repellent facades. With deep penetration and high efficiency, it protects your exterior surfaces from moisture, dirt, and weathering for years.
