MARMURIT GT – Primer for mosaic renders
Coloured product based on an acrylic dispersion and mineral fi llers intended for proper preparation of substrates for MARMURIT, MARMURIT COLORATO and MARMURIT AKORD mosaic renders. For priming of all typical construction substrates outside and inside buildings, including in EWI systems: KABE THERM MARMURIT COLORATO / MOZAIKER COLORATO* and KABE THERM MARMURIT / MOZAIKER*. For use on mineral substrates (e.g., concrete, cement, cement-lime render) and on substrates covered with a well-bonded plastic-based paint coating. Note: An absorbent substrate requires priming with BUDOGRUNT ZG (outside) or BUDOGRUNT WG (inside) before applying the product.
| Base binder: | co-polymer binder; |
| Pigments: | organic and inorganic colour pigments; |
| The content of volatile organic compounds VOC: | cat. A/g. The product contains less than 30 g/l VOC; |
| Colour: | white or tinted to match the colour of the render; |
| Average coverage: | approx. 0.20 l/m² (depending on the substrate absorbency); |
| Density: | approx. 1.4 g/cm³; |
| Contents of solids: | approx. 55%; |
| Temperature of application (air and substrate): | from +5°C to +25°C; |
| Relative air humidity: | ≤75%; |
| Packaging: | Disposable plastic packaging containing 5 and 10 litres of product. |
| Storage: | Product should be stored in sealed packaging, in a cool room, but protected from frost. Opened packaging should be tightly closed and used as quickly as possible. |
| Shelf life: | 18 months from the date of production printed on the packaging, with originally sealed packaging. |
• Improves the render coat adhesion
• Reduces and equalises substrate water absorption
• Reduces the eff ect of substrate showing if it
is coloured to the render colour
• Facilitates render application and texture modelling
• Features a very good adhesion to both mineral
substrates and plastic-based paint coatings
SUBSTRATE PREPARATION: Substrate should be sound/stable (without scratches and cracks), degreased, even and dry, as well as free of biological contamination and chemical efflorescence. In case of algae/fungi growth, the substrate should be cleaned mechanically and then washed with water and disinfected with ALGIZID. Any loose layers, not bound to the substrate (e.g., loose render or flaked coatings), should be removed. Old and/or dirty substrates should be washed and degreased with water and CLEANFORCE cleaning agent. For particularly uneven substrates (from 5 mm to 15 mm), first use filling compounds, and then level out the wall surface with KOMBI or KOMBI HYDRO STOP adhesive/base coat. Minor unevenness (up to 5 mm) can be levelled out and smoothed straight away with KOMBI or KOMBI HYDRO STOP adhesive/base coat. An absorbent substrate should be primed with BUDOGRUNT ZG (outdoors) / BUDOGRUNT WG (indoors) before applying levelling compounds or base coats. If the product is applied on new mineral substrates (i.e. concrete, cement render and cement-lime render) – a minimum 2-week curing period is required.
PRIMING: Absorbent substrates should be primed first with BUDOGRUNT ZG (outside) or BUDOGRUNT WG (inside).
PRODUCT PREPARATION: The packaging contains a ready-to-use product. It cannot be diluted.
APPLICATION: The product should be applied on the substrate with a paint brush or roller.
DRYING: The curing period of the product applied to the substrate before applying the render is about 24 hours. Protect the freshly applied coat against precipitation and condensation until it dries completely. Closed rooms should be ventilated after priming.
USEFUL HINTS: During the application and drying of the product, rainless weather should prevail, with an air temperature above +5°C. Drying time may be longer due to low temperatures and high relative humidity. If this is the case, it is necessary to wait until the primer dries out completely before applying the render. Tools should be cleaned with water immediately after work is completed. Avoid applying the product on surfaces directly exposed to sunlight or during strong wind. In order to protect the undried product layer against severe weather conditions, it is recommended to use appropriate protective meshes on scaffolds.
