SILIKATFÄRG

Silicate paint

Water-borne, inorganic, one component, full-matt facade and indoor paint for mineral surfaces, with potassium waterglass as binder.

SILIKATFÄRG is a traditional facade paint for mineral surfaces. It is also suitable for painting of walls and ceilings indoors where a traditional full-matt appearance of the painted surface and/or breathability is required: houses, commercial, industrial and storage buildings as well as caves, cellar spaces etc. For painting of lime plaster, lime cement plaster and cement plaster as well as concrete, cement fibre board and lime-sand brick. SILIKATFÄRG can also be used for maintenance painting of surfaces previously painted with lime paint, lime cement paint, cement paint or silicate paint.

Surface preparation

NEW SURFACES: New concrete element or cast surfaces can be painted with SILIKATFÄRG when a minimum of one month has passed after the casting, the surface is completely bound and no longer wet or matt moist. In measurements the moisture values of the concrete must be under 97 % as relative humidity (RH) or 4 % as per cent by weight. It is recommended that new plaster surfaces are coated only after a hardening time of 6-8 weeks. Remove all dirt, dust and other loose impurities from the surfaces by cleaning with high pressure washer, if needed. When needed, add sand to the washing water or use a steel brush or similar in order to achieve sufficient surface profile (e.g. mould-cast surfaces). NB! When painting concrete element, laitance must be removed before painting. PREVIOUSLY PAINTED SURFACES: Remove flaking and poorly adherent or chalking, pulverized (e.g. lime wash) old paint coats. The method to be used is chosen depending on the strength of the substrate and the type of the paint to be removed (e.g. wire-brushing, hot pressurized-water cleaning or water-sand cleaning). Remove also poorly adherent, brittle plaster and concrete surfaces. Patching of the plaster and other repairs are made using appropriate mortars to the level of the surrounding surface. Finish the repaired areas carefully and let them harden before they are painted.

Application

Priming is not needed on solid cement plaster, concrete or painted surfaces. Strongly absorbent porous substrates, such as plaster and surfaces painted with lime paint, are pretreated with SILIKATBINDER Silicate Primer diluted with water in the ratio of 1:1. PRIMING is done with a mixture of SILIKATFÄRG Silicate Paint and SILIKATBINDER Silicate Primer. Mixing ratio 2:1. Before use stir the paint thoroughly. SILIKATFÄRG Silicate paint is top coated once or twice depending on the opacity of the colour and the desired surface structure. The paint may be diluted with water by 5 – 10 %. Reserve a sufficient amount of paint of the same manufacturing and tinting batch for each uniform surface to prevent possible colour differences. Plan the application so that the working joints and seams are placed along natural lines of the structure.POSSIBLE TOUCH-UP PAINTING: When painting e.g. repairs caused by rack mounting, colour differences may be diminished by adding abt. 10 % SILIKATBINDER Silicate primer into SILIKATFÄRG Silicate paint. NB! Silicate paint is corrosive. Protect glass, glazed, natural stone and metal surfaces. Apply the paint by brush, stippling brush, roller and/or airless spray. Recommended nozzle size for spray is 0.017 - 0.021".

Application conditions

During the application and drying period the temperature of the ambient air, the surface and the paint shall be above +10 °C and the relative air humidity below 80 %. Avoid painting in direct sunlight.
