MARMURIT COLORATO – The system of composing mosaic render blends, based on coloured, broken marble aggregate
MARMURIT COLORATO render is a two-component composition of binder based on acrylic resins and coloured aggregate with a grain size of 1.0 and 1.5 mm. The binder is supplied in a tightly closed container with thoroughly measured portions of aggregate in the colours conforming to the Manufacturer’s catalogue. The render is formed by means of mixing selected aggregates with adhesive in appropriate portions pursuant to the recipe. MARMURIT COLORATO render is used for manual application of thin top coats inside and outside buildings including KABE THERM MARMURIT COLORATO / MOZAIKER COLORATO EWI system based on EPS. It is especially recommended for the decorative finishing of walls in rooms of heavy traffic (such as staircases, entrance halls, corridors and passageways) as well as architectural elements to be found on the facades of buildings (i.e. pedestals, pilasters, cornices). The product may be applied in housing and public utility buildings as well as educational, boarding facilities and health service facilities. To be applied on mineral substrates (i.e. concrete, cement render, cement-lime render) and on substrates covered with well set polymer-based coatings. Before applying the render the substrate has to be primed with MARMURIT GT, while absorbent substrates also with BUDOGRUNT ZG or BUDOGRUNT WG.
Note: Because of the product specificity, it is not recommended for applying on surfaces exposed to a long-term and direct exposure to water and precipitation such as swimming pools, wading pools or uncovered
fencing walls. Before composing the melange, check the numbers of the batches of aggregate (component B). Do not mix different batches of aggregate for the same surface (if necessary, mix them beforehand, make them uniform)!

SUBSTRATE PREPARATION: Apply to a sound/stable and clean substrate (without cracks and delaminations), degreased, even and dry, and biological or chemical efflorescence free. In case of algae/fungi growth, the substrate should be cleaned mechanically and then wash with water and disinfect with ALGIZID. Any loose layers not bound to the substrate (i.e. loose render or flaked coatings) should be removed. Old and/or dirty substrates should be washed off and degreased with water and CLEANFORCE cleaning agent. If there is any large unevenness to the substrate (from 5 to 15 mm). Even a wall with levelling compound, and then apply the whole surface with KOMBI or KOMBI HYDRO STOP base coat. Minor unevenness (up to 5 mm) can be levelled out at once and smoothened with KOMBI or KOMBI HYDRO STOP base coat. Absorbent substrates should be primed with BUDOGRUNT ZG / BUDOGRUNT WG before levelling
compounds. Fresh concrete substrates, cement renders and cement-lime renders may be rendered only after a 4 weeks of curing, plasters after 2 weeks, while drywall systems directly after grinding and dedusting. Prior to using render in KABE THERM MARMURIT COLORATO/ MOZAIKER COLORATO EWI system, all coats of EWI system should be applied in accordance with the requirements for external thermal insulation composite system (ETICS). The mosaic render can be applied onto a primed surface only when reinforcing coat is completely dry, i.e. after 3÷4 days under normal conditions.
PRIMING: On the substrates which feature high absorption, it is recommended to apply BUDOGRUNT ZG primer (outside) or BUDOGRUNT WG primer (inside) in advance. The substrate should be primed with MARMURIT GT coloured
primer before applying the render. Primer should be dry before applying a finish coat, curing period lasts about 24 hours. To reduce the risk of the substrate colour showing through the top coat, it is recommended to use a primer that is of the same colour as the melange mosaic render.
PRODUCT PREPARATION: The packaging contains a ready-to-use product. Before application, the product should be thoroughly mixed with a low-speed mixer fitted with a basket stirrer until a smooth, homogenous consistency is
obtained, from 30 to 60 seconds. Further mixing is not recommended as it may result in durable deterioration of the product aesthetics.
APPLICATION METHOD: Mosaic render should be applied on the substrate (from the bottom to the top) in the form of a thin levelled layer with the use of a stainless steel trowel. Using a stainless steel trowel, the product applied on the substrate should be gently levelled. The layer applied should be even and cover the substrate completely without any hollows or bulges. Note: It is not allowed to rub the product applied on the substrate. If an excessively thin layer of render is applied, it may lead to formation of cracks on the surface, which has a negative impact on its aesthetics and durability.
DRYING: Typical drying time ca. 24 h (20°C, 55% RH). Note: The drying time may be longer due to low temperatures and high relative humidity. To assist the drying of the finish coat, the surface should be protected against precipitation and condensation. After applying the render, the rooms should be aired for the period of 2 weeks; only after the end of this period, they may be fully used.
USEFUL HINTS: The final effect may depend on the substrate type. This is why for non-uniform substrates, it is recommended to apply the whole surface with KOMBI or KOMBI HYDRO STOP base coat in advance. To avoid colour
differences, a single batch product should be used on a single application / architectural element. ‘Wet on wet’ method should be used. All tools should be cleaned with water after work is completed. To be applied on dry days at temperatures between 5-25°C. Avoid applying in direct sunlight or during strong winds. To protect the still wet top coat against inclement weather conditions, scaffolding should be covered with a protective netting or tarpaulins.
