Granomin KR is used as a decorative façade render on Granol'therm EWI systems. It can also be used as a finishing render on all mineral surfaces, interior and exterior.

Cement based render according to DIN 18557 with properties as the P I C mortar group, water-repellent, according to DIN 18550. It consists of standardised mineral fixing agents, admixtures with the right grain size and proven supplements.

The range offers a wide variety of colours in line with our samples. Sample colours are to be selected from our 48 Granicem colours card. Special colour shades can be provided as agreed. On EWI systems it is prohibited to use colours with a brightness value below 20. Colour variations in the treated surface cannot be avoided due to the use of natural raw materials and drying processes influenced by environmental influences. For subsequent deliveries the rest of the material present must be continually mixed with the new material to guarantee uniformity of colour.

Non-flammable according to building material class A according to DIN 4102, water apour-open, weather-resistant, does not swell, hydrophobized on the basis of the advantageous E-modulus, it offers the best possible protection against crack damage.

Granomin KR adheres to all load bearing mineral surfaces. Surfaces should be clean and dry and free from surface dust, mortar remains (snots), soiling, atmospheric pollutants, etc. A Granol’plus STG primer is applied to this pre-treated surface. The conditions of DIN 18550 and VOB, part C (in each case the latest versions) must be observed. If in doubt about the surface consult our technical application advice department.

With manual application each bag of dry mortar is intensively mixed with 6 - 7 litres of clean water. A constant mixing time and consistency must be ensured when stirring to guarantee a uniform as possible hue and structure in the plaster. With manual application, after a waiting time of approx. 5 minutes the product needs to be mixed again. Application takes place with a high-grade stainless steel plasterer's trowel or spraying device suitable for the grain thickness. Then smooth with a plastic plasterer's trowel or mortar board. Open treatment time approx. 2 hours. Granomin KR can also be applied with any customary plastering machines on the market, where the manufacturer's instructions must be followed. To prevent day joint lines the labourers must treat the adjacent surfaces on the scaffold working above each other “wet on wet". With larger surfaces it is advisable to continue plastering up to the end of a section (plaster strips, recesses, drainpipes, etc.). The patchy or cloudy drying of the coloured top plaster layer due to varying ambient conditions cannot be excluded, and is therefore not a material fault. Apply a equalizing layer to prevent colour variances. Protect the fresh plaster against rain and fast drying. Measures such as providing sheeting to protect the façade or scaffolding are particularly necessary with direct sunlight and wind. Do not apply with surface and/or ambient temperatures below + 5° C. Clean tools and equipment with water immediately after use. Carefully cover surrounding parts such as windows, window sills, etc.

In 25 kg paper bags stacked on Europallets. Store the material in a dry place.

New buildings must be able to continue to dry out after the commencement of the insulation work so that colour differences in the finishing plaster due to excessive moisture migration to inside or outside are avoided. Mixing with fixing agents and additives is not permissible.
