Long-lasting protection for façades and masonry
Remmers Funcosil SNL is a high-quality water-repellent impregnation widely used by both private homeowners and professional façade specialists. The product is renowned for its exceptional durability and deep penetration into mineral substrates.
After treatment, façades remain clean for a long time and are effectively protected against moisture penetration, pollution and harmful external influences. By preventing moisture ingress, the thermal insulation performance of the façade is also improved.
Application areas – Remmers Funcosil SNL
Funcosil SNL is designed for water-repellent impregnation of porous, mineral substrates, such as:
Commonly used for:
Also suitable for previously hydrophobised substrates.
The 30-litre container is highly economical and ideal for large surface areas.
Properties of Remmers Funcosil SNL
-
Extremely water-repellent with strong beading effect
-
Vapour-permeable – prevents trapped moisture
-
Very high penetration depth
-
UV-, light- and weather-resistant
-
Extremely durable (>10 years protection)
-
High active ingredient content
Technical information – Funcosil SNL
Funcosil SNL is a reactive, oligomeric siloxane solution for the water-repellent impregnation of mineral building materials. Due to its low molecular structure, the product penetrates deeply into the substrate.
After application, the active ingredient reacts with the moisture present in the material, forming a water-repellent, UV- and weather-resistant protective layer. This layer bonds to the pore and capillary walls without affecting vapour permeability.
As a result:
-
Water absorption is significantly reduced
-
Uptake of harmful substances is limited
-
Growth of microorganisms is reduced
-
Freeze–thaw resistance is greatly improved
-
Energy loss through the façade is reduced
Application instructions – Remmers Funcosil SNL
-
Use a low-pressure sprayer (e.g. garden or weed sprayer)
-
Pour Funcosil SNL easily using the integrated spout
(for 30-litre containers, the use of a funnel is recommended)
Apply the product so that the substrate is completely saturated. Application can be carried out:
Important during application:
-
Do not atomise or mist (avoid high pressure or fine nozzles)
-
The liquid should flow as a film of approx. 30–50 cm down the façade
-
Treat defined façade sections without interruption to avoid missed areas
Small or complex areas that cannot be treated by low-pressure flow may be treated with a brush or roller, provided these are regularly dipped into the impregnation liquid to ensure sufficient material application.
After application:
-
Protect the treated surface from rain for at least 5 hours
-
Avoid strong wind and high temperatures
-
Ideal application temperature: 5–25 °C
