Property profile
Remmers Funcosil WS is used to hydrophobize porous, mineral building materials such as sandlime brick, natural stone, fair-faced brick masonry work, mineral renders, aerated and light-weight concrete. It can also be used to subsequently treat water glass paint coatings.
- Single component, environment-friendly, water based impregnation agent.
- Excellent water repellency
- Pronounced penetration even on damp substrates
- Alkali stability
- Dries clear
- Practically odourless
- No emission of pollutants
- Greater job safety
Directions
Apply Funcosil SE generously in a low pressure flow coating procedure, using a wide spray nozzle, so that a 30 - 50 cm long film of liquid runs down the surface of the building material. While applying, the nozzle should be led along the facade and the material immediately worked over with a brush. This process is repeated several times. Funcosil SE is to be applied, wet-on-wet, from top to bottom. To avoid missing places, limited sections should be completely impregnated without interruption at a time. For smaller, complicated surfaces that do not allow a spraying procedure, work can be carried out with a brush. The only way to avoid insufficient application rates is to saturate the brush well. Freshly treated surfaces should be protected from driving rain for at least 5 hours. Strong wind and sunlight can accelerate the evaporation of the carrier agent which negatively influences penetration depth. Funcosil WS can also be applied to slightly damp building materials.
Working temperature:
Hydrophobizing impregnation measures can be carried out at temperatures between 10°C and 25°C. Strong heating of the surfaces through sunlight can be avoided by using awnings. At temperatures below 10°C, evaporation of water (carrier agent) can be delayed. The full effectiveness of the impregnation develops 1 - 2 weeks after treatment, depending on weather conditions.
