Star line is the silvery version of Mica D’oro. itis a lime-based decorative finish that features a unique combination of textured and smooth areas, creating subtle variations in color intensity that lend a warm and inviting atmosphere to any space. The finish also features flickering speckles of silver micas that add a touch of luxury, making it suitable for a wide range of design styles, from elegant and refined to rustic and charming.
One of the key benefits of Star line is its exceptional resistance to abrasion, making it a great option for exteriors as well as high-traffic interiors such as prestigious shops, public offices, and commercial buildings. Its durability and resistance to wear make it an ideal choice for spaces that require a finish that can withstand heavy use. The combination of durability and aesthetic appeal make Stars an excellent option for both residential and commercial spaces.

Application Instructions
WARNINGS: Water on the surface of the material in the bucket is normal and should be removed before use or addition of colourants. All lime-based products lose their viscosity when mixed and need a period of 6/12 hours after mixing to regain their density. This product is dense, and ready for use; thus it may be necessary to use an appropriate drill attachment to stir for a few minutes to reduce viscosity. Choose the colour and add the toner additive to the container and continue mixing until a homogeneous shade is obtained. Let the product rest for about 5 hours before you begin to use it.
We recommend using materials from the same production batch for the same project. If you must use different batches, we suggest mixing their material together to avoid any slight variations in shading. To ensure proper usage, dilution, and application of the products mentioned in these pages, please consult the corresponding technical data sheets.
When preparing the surface and applying the materials, we advise using appropriate tools and personal protective equipment (PPE). During application and for the following 72 hours, protect the surfaces from sudden temperature change, direct sunlight, and water. Don’t apply in temperatures below 8°C or above 35°C. During application make sure that the work area isn’t too damp to avoid problems with application times.
Remember to have a strong light parallel to the wall and situated on only one of the two sides of the wall you are working on (usually on the same side as other sources of light such as windows). In this way, the shadow of the trowel allows you to see the actual state of the finish. Every so often, during the second and third coats, the light should be moved so that the wall doesn’t dry out too much in one spot from the heat of the lamp.
Application
Protection of the Work Area: Masking tape and protective material over the baseboards and around windows and doors.
STAR LINE can be applied on rough and smooth plasters, new and old. Existing paints need good brushing to remove surface dust and the inconsistent parts. Where necessary, apply a layer of QUARTZ PRIMER or UNIVERSAL PRIMER laid with a brush or roller, diluted with water according to the instructions. The possible presence of water on the surface of the tub is to be considered normal. Remove it completely before use or coloring. Mix the material with a mixer. All lime-based products lose their viscosity when agitated and require a rest period of about 6 hours after mixing, to return to their density. The product is very dense and ready to use, therefore for colouring will be necessary to mix the material for about a minute, to decrease its viscosity. Choose the colour. Introduce all the toner additive into the tub and continue the mixing until the colorant is completely homogenized. Before applying, let the product rest for about 6 hours to regain its original density. The application must be carried out with a steel trowel in two coats. The application of the first coat is carried out with a metal trowel with a consumption of about 1800-1900 g/sqm. The next day, or at least when the first coat is completely dry, apply the second one with the same method and consumption. When the surface begins to dry, level it up with SPONGE FLOAT COARSE. Let it dry about a 30-40% and then press the surface with the blade of the metal trowel. If you do this smoothing too soon, you risk smoothing out all the surface, almost like a Marmorino. If you do it too late, you fail to create smooth areas that, in a properly applied finish, must alternate with the rough ones. This pressing can be continued until the smooth area becomes almost shiny. The blade has to be moved in different directions to avoid the creation of ridges (“chatters”).
Exteriors
For exterior applications, there are some rules to respect and some precautions to take. We remind you that carbonation, i.e., the process that takes place through the absorption of atmospheric CO2, is completed in a few hours on the surface but takes several days to take place in depth. It is therefore important that the application takes place in the certainty of the absence of heavy rains in the three following days. It is also not recommended to apply it on walls that do not have at least a small roof overhang. Penetrating rain could ruin the finish even after weeks as deep carbonation is completed after more than a month. Avoid windy days, especially at high temperatures, as well as the risk of frost in the 48 hours following application. In external applications in hot climate conditions, it is also recommended to protect the wall from the sun with shade cloths applied to the scaffolding. Lime-based products must dry slowly to better fulfil their characteristics.
The application should be continuous and without linear brakes in the wall.
Finish Protection Interiors: A protective treatment is optional in most circumstances. It is however
necessary in bathroom, kitchen, and splashback walls.
Exteriors: This finish, as all lime-based plasters, absorbs water during rainy weather,
which results in a temporary "wet effect" on the surface. However, this plaster releases
the absorbed water within a few hours, allowing the surface to dry without any damage

nor alteration to the finish. While a final treatment is therefore optional, it is highly
recommended in areas with high pollution levels or if you wish to avoid the temporary
wet effect that can occur after rainfall.
INTERIORS / EXTERIORS: after about 72 hours at least 20°C., proceed with the
application of the colourless protective impregnation HYDROCALCE, especially
designed for the protection of external lime-based coatings. Its Installation is done by
brush in two coats, with a consumption of about 100-130 g/sqm.
