Application Instructions WARNINGS

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

April 23 TDS BETON STUCCO 3 of 4

Protection of the work area: Masking tape and protective material over the baseboards

and around windows and doors. BETON STUCCO can be applied with a metallic

trowel in two coats on a well prepared background (with primer) leaving the first coat to

dry completely before applying the second one. The second coat must be applied quite

thick and pressed, smoothed and scratched with a trowel, brush trowel, scraper or

other tools depending on the desired effect. It is possible to reproduce the typical joint

ridges that come from the connection of concrete panels. The following day, on a

completely dry surface, sand it by hand or with a machine.

ALTERNATIVE APPLICATION METHOD: Concrete tears

Apply with the metallic trowel in three coats on a well-prepared background (with

primer) leaving the first coat to dry completely before applying the second one. The

second coat has to be applied quite thick and, after about 30 minutes, apply a very thin

third coat, press and smooth out. After a few minutes, to obtain the typical holes and

tears of concrete, place the blade of the trowel very flat against the wall and, after

making pressure, pull it with the blade always parallel to the wall. If the timing is right,

you should create a tear. Then, let it dry a little and, when it begins to dry, spray a little

water. With the flat blade against the wall and random movements, flatten the surface.

Be careful not let water drip down on the wall: the drops could leave white marks.

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.

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.

Interior: HYDROCALCE / MARSEILLE SOAP / MOROCCAN OLIVE OIL SOAP

Exterior: HYDROCALCE

Furniture: PU1C

April 23 TDS BETON STUCCO 4 of 4

HYDROCALCE: 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.

MARSEILLE SOAP / MOROCCAN OILIVE OIL SOAP / PU1C: apply after at least 36

hours from application of the finish

Maintenance Little maintenance is needed, brush off dust occasionally.
