SEFAB® SILIKON
Silicon acrylic facade colour
Description
Sefab silikon is one ingredient, maleable facade material based on acrylic silicon modified dispersion. It is suitable for outdoor use. Colour shades are available by use of foreign made colour – Clariant fast pigments. It stays very firmly attached to silicate surfaces. It is resistant against rain water (washable), it has low diffusion resistance, and a life of at least 20 – 25 years. This product is also environmentally friendly.
Use
Suitable surfaces are lime-cement plasters, concrete, brizolit, and cement-chip boards. It is used to create coloured layers in places with higher dust and smog levels, where the product is more resistible than normally used facade paints. The paint is not suitable for constantly wet surfaces, calcareous grouts, front coatings, or for weather-worn plasters.
Preparation of the surface (penetration)
New surfaces must be dry and carbonized (min. 4 – 6 weeks). Penetration paint and two paints made with Sefab silikon colour are used as a surface preparation. Penetration is performed by adulterated acrylic dispersion Sokrat 2802, and copolymer impregnating preservative S 1862, S 1865 at 1 (dispersion) to 4 (water) ratio. 1 (dispersion) to 5 (water) ratio is used on new, more firm, liquid absorbing surfaces.
Surface coating
First painting must be done at least 4 hours after penetration by brush, paint-roller, or spray-gun. Second painting can be done at least 12 hours after first painting. Temperature of the air during the work and drying of the paint must be at least + 5*C.
