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 sun light and water. Don’t apply in temperatures below 8°C

or above 35°. 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 coat, 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.

Mica D'oro ,  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 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.

Maintenance Little maintenance is needed, brush off dust occasionally.
