The GRANIT and MINI GRANIT plasters are suitable for creating ornamental items on exterior and interior walls of old and new buildings, as well as for cover plastering of footings and fences, and facade thermal insulating systems. It is not recommended for coating horizontal or nearly horizontal surfaces. The plaster cannot be used if the structure is exposed to humidity for a long time.
Priming of the wall surface shall be completed 24 hours prior to the application of the plaster. Take care to apply the primer uniformly and to make sure that the primer is entirely solid before starting the application. Make available a quantity necessary for a single surface as determined by calculation prior to starting the application. The product contains minerals of natural origin, therefore, minor difference in colour shades could occur in subsequently ordered products, or in buckets containing products from different filling dates. Use materials with the same filling date at each respective wall of the building, or the products in buckets with different filling dates should be mixed in a larger vessel. This process should be done with mixing blade attached in a drilling machine. Subsequent orders shall be submitted to the place where the purchasing was made formerly. The colours on the sample materials and on the colour charts are given for information, for which the Revco undertakes to ensure colour stability, but the full equivalence of colours cannot be guaranteed. Excessive agitation could lead to foaming and discoloration. Marble plaster cannot be used if the waterproofing of the wall is not appropriate.
GRANIT plaster, MINI GRANIT: with PRIMER wall impregnating agent
Required quantity: 0.1 - 0.2 l/m2
Application can be made with brush or cotton roller.
No priming is necessary in case of clean, homogeneous, non absorbent surface.
Tools: Only stainless steel smoothing trowel. Tools can be cleaned with water immediately after use.
Spreading: Apply granite plaster by means of stainless steel smoothing trowel on the surface uniformly. The quantity of material applied shall be matched to the particles size. The granite plaster shall be smoothed always in one direction. Do not perform the smoothing operation for a long time in order to prevent the material from becoming grey, and take care not to separate the grains. Make sure that the application of granite 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 or humid air, because such conditions could lead to cracks during drying and application periods. Protect the surface from extreme weather conditions for a week after the application. Any subsequently repair on the surface could lead to discolouring in spots. The discolouring showing a milky appearance would clear off after a time.
Granit plaster: 2 mm 5.5 kg/m2
Mini Granit plaster: 1 mm 3.5 kg/m2
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: not necessary
Temperature: The temperature of air and wall surface shall be between +5 °C and +25 °C.
Total drying time: 12 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).
Cleaning: It can be cleaned with fine bristle brush and water. Avoid using of any detergent and cleaning agent.
Overcoating: The surface can be later overcoated with granite plaster, or with outdoor paint VARIO Exterior.
Storing: One year in unopened original packaging at a place free from freezing. Carefully close the bucket after using.
Specific gravity: 1.60 kg/l
Density (at 20 °C): 1.6 g/cm3
Non volatile part: 81 % (m/m) (at 105 °C, 3 h)
Packaging: 15 kg
Permit: CE: EN15824
Protect the material during the drying period from direct sunshine, draught, freeze, splashing rain, temperature above 30 °C. Clean the tools, mixing vessel and drops immediately after use, because only mechanical cleaning is possible after the material has dried. Take care to avoid contact with skin or eye, and if such contact still occurs, then wash with plenty of water and seek medical assistance if required.
