Intended for protective and decorative rendering coats in the KLEIB external thermal insulation system with rendering coats. It can be used on any mineral surface which is even and sound. It can also be applied on surfaces of building base courses, wall bases, balcony balustrades, fencing elements, as well as in interiors where increased mechanical resistance is required, such as staircases, corridors, halls etc.

The working surface should be stable, firm, dry and even – without any damage or surface roughness, as such defects may be visible after applying the plaster. Surfaces should be primed using KLEIB C3, and when this has dried (no later than 72 hours) the plaster may be applied. In case of dark composites of aggregate in mosaic plaster it is recommended to use body-tinted KLEIB C3 primer in the colour matching the brightest coloured quartz aggregate.

The contents of each package should be mixed using a low speed electric drill until a smooth uniform consistency is obtained. In order to avoid the mortar forming a foam, rapid stirring should be avoided. If the mixture is too thick, up to 100 g of water may be added per each 16 kg packaging. The user may add stained quartz aggregate to the package with premix. The user has at their disposal marked packaging units of aggregate whose composition may be set in accordance with the KLEIB M9 colour range or determined independently according to taste. After pouring the portions of aggregate into the package with premix, the contents should be mixed using a mixer attachment on a low-speed electric drill.

Apply with a stainless steel plasterer’s float to a thickness of a grain of aggregate. Then the entire surface should be smoothed and trowelled using a plasterer’s float to achieve an even surface. It must be performed within 72 hours of priming the surface. Do not apply the mortar on moist surfaces. Tools should be washed with water immediately after use.

3.1-3.5 kg/m² for grain size of 1.0-1.6 mm

KLEIB M9 should be stored in tightly closed tubs in dry conditions and plus temperatures, for up to 12 months from the production date on the packaging.
