Proven effect Funcosil SNL: >10 year.
Shelf life: minimum 24 months
Property profile Funcosil SNL
- For hydrophobizing impregnation of porous, cementitious building materials such as brick and clinker masonry work, fair-faced sand-lime brick masonry work, cementitious renders, fibrated cement, aerated concrete, light-weight concrete and modular concrete blocks, natural stone. Can also be used on surfaces already hydrophobized.
Field of application
- Protection of facades against driving rain
- Reduces susceptibility to dirt and green discolouration
- Subsequent treatment/renewal of hydrophobic surfaces
- Subsequent impregnation of mineral paint coatings
- Porous, mineral building materials such as brick masonry work, sandstone/sand-lime brick, mineral renders and aerated concrete
Properties
- Odour-neutral
- Improves resistance to frost and de-icing salts
- Highly water-repellent
- Enables water vapour diffusion
- Outstanding penetration
- UV-resistant
- Alkali-resistant
- Excellent long-term effect
- Reduces energy loss
Difference between Funcosil SNL and Funcosil SNL Odourless
Funcosil SNL has low odour emission in contrast to Funcosil SNL Odourless which is as the name indicates completely odourless.
Directions for application of Funcosil SNL
The Funcosil SNL is applied under gravity in a flow coating procedure generously enough that a 30-50 cm long film of liquid runs down the building material. The nozzle should be held horizontally and led along the facade without interruption. After the Funcosil SNL has been absorbed, the process is repeated several times. Spraying pressure and nozzle diameter should be selected so that misting does not occur. To avoid missing areas, limited sections should be completely impregnated without interruption. A brush or roller can be used for smaller, complicated surfaces that do not allow a spray application. In this case, the required application rate can only be achieved by working with well saturated tools. Protect the freshly impregnated surface from driving rain for at least 5 hours. Strong wind and sunlight may accelerate evaporation of the carrier which has a negative influence on penetration depth. The surface of less absorbent substrates should be washed off with V 101 Thinner half an hour to an hour after application to remove excess material which could create a gloss.
Working temperature: Water repelling impregnation is preferably carried out at temperatures between +10 °C and +25 °C. Sun awnings can be used to prevent surfaces from heating too strongly. At temperatures below 10 °C, evaporation of the carrier and formation of the active ingredient may be considerably delayed.
