Remmers Funcosil SN – Water-Repellent Impregnation (5L)

Packaging: 5 liters
Remmers Funcosil SN is a colorless, water-repellent facade impregnation based on silane/siloxane. It is specifically developed for solvent-sensitive materials and delicate connection zones. Funcosil SN penetrates deeply into porous mineral substrates, providing reliable protection against moisture, rain, and dirt, while maintaining the vapor permeability of the material. It is safe for use on solvent-sensitive building materials such as polystyrene (insulation boards) or bitumen.

Applications

Funcosil SN is suitable for water-repellent treatment of various porous mineral surfaces:

• Sand-lime brick (smooth or rough/broken)

• Fiber cement

• Fine porous brick masonry

• Plaster layers and stucco

• Insulation plaster

• Aerated concrete

It is ideal for renovation or protection of old, weathered facades, especially where solvent-sensitive materials are present, such as cavity insulation or styropor finishes.

Key Features

• Water-repellent — prevents penetrating moisture

• Vapor-permeable — allows water vapor to escape

• Deep-penetrating — ensures long-lasting hydrofobation

• UV and weather-resistant — suitable for all weather conditions

• Alkali-resistant — compatible with various mineral substrates

• Safe for solvent-sensitive materials such as polystyrene and bitumen

• Improves frost and de-icing salt resistance

• Long-lasting protection when applied correctly

Application Tips

• Ensure substrate is clean, dust-free, and dry

• Apply Funcosil SN without pressure by flowing, forming a 30–50 cm liquid film

• Immediately work over with a block brush from top to bottom; repeat until no further absorption occurs

• For hard-to-reach areas, use a well-saturated brush

• Protect freshly treated surfaces from rain, wind, and sun for at least 5 hours

Consumption per m²

• Smooth sand-lime brick: min. 0.5 L

• Rough/broken sand-lime brick: min. 0.7 L

• Fiber cement: min. 0.3 L

• Fine porous brick masonry: min. 0.8 L

• Plaster layer: min. 0.5 L

• Insulation plaster: min. 0.6 L

• Aerated concrete: min. 1.0 L

Actual consumption depends on substrate porosity and method of application. Test a trial area first.

Why Choose Remmers Funcosil SN

Remmers Funcosil SN provides durable facade protection, even for areas with solvent-sensitive materials. The colorless formula preserves the natural appearance of the facade and ensures long-lasting hydrofobation without limiting vapor permeability. Funcosil SN is easy to use, suitable for renovation and new construction, and a cost-effective solution for long-term facade protection.
