Provides coating with outstandingly good vapour permeability, which can be cleaned efficiently.
The SILICON Spachtel plaster is suitable for creating ornamental items on exterior and interior walls of old and new buildings, as well as for cover plastering of thermal insulating systems using mineral wool. This is the best coating for historical buildings.
The substrate shall be free from dust and dirt, and the full layer thickness shall be dry. In case of plastered surface and concrete wall the substrate shall be load bearing, as well as free from movement and shrinkage. The surface shall be smoothed or filled. Remove the lose, damaged layers and paint residue, then repair the surface defects prior to the application of primer. At the same time, make sure that the repaired parts have the same structure as the existing surface. Expert opinion should be obtained before using thin plaster for repairing of wall surfaces formerly provided with ornamental plaster (e.g. stone powder). The plaster cannot be used, if the structure is expected to be exposed to humidity for a long time.
Exclusively with PRIMER plaster primer.
IMPORTANT! Always use a primer which has a colour identical to that of the colouring plaster.
Tools: stainless steel smoothing trowel or spray gun.
Spreading: Apply thin plaster by means of smoothing trowel on the surface uniformly, and then rub it with plastic smoother. Perform the rubbing with circular motion. The quantity of material applied shall be matched to the particles size, so that structural differences could not occur because of excessive or inadequate quantity of material. Always remove the extra material appearing on the plastic smoother. Do not perform the smoothing operation for a long time in order to prevent the material from becoming grey. Make sure that the application of thin plaster is made without interruption, because setting of the material starts after long waiting time, and the possibility of blending the parts is reduced. Establish work joints at borders of colours by applying tapes, or along the edges. Do not apply the materials in extreme weather conditions, such as strong sunshine, during rain, at freezing temperatures and during strong wind, because such conditions could lead to cracks during drying and application periods.
Required quantity: 1.5 mm 2.5 kg/m2
The required quantity is less by 30-50 % when the application is made by spray gun. The specified quantities refer to smooth substrate. The quantity required for rough surfaces should be checked on site. We cannot assume responsibility regarding the required quantities.
Thinning: with max. 2 % water
Premixed in the factory in colours of the VARIO colour chart.
The temperature of air and wall surface shall be between +5 °C and +25 °C.
Total drying time: 10 h
The specified values are valid at a temperature of 20 °C and a relative humidity of 42 %. The drying time may be significantly longer if the weather changes (low temperature, high humidity content).
Overcoating interval: at least 24 hours.
The structure will change after overcoating the plaster.
It can be cleaned with fine bristle brush and water. Avoid using of any detergent and cleaning agent.
Two years in original packaging at a location free from freezing. Carefully close the bucket after using.
