Application Instructions WARNINGS

February 24 TDS PASTELLONE 3 of 8

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/floor and situated on only one of

the two sides of the wall/floor 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/floor doesn’t dry out too much in one spot from

the heat of the lamp.

APPLICATION on the ideal substrate: plaster made of cement and sand

Substrate: A water-based primer, like our UNIVERSAL PRIMER is applied with a roller

on a surface free of dirt and grease. If you already have pre-coloured material in your

warehouse, use this for all three coats. If you have white material, you can use this for

the first coat in order to simplify preparation; it saves time and colourant. Remember

that PASTELLONE comes in two versions: MEDIUM for the first coat and FINE for the

second and third coats, although many applicators prefer to use MEDIUM for all three

layers to get a stronger finish. Mix the material for the first coat with water to make the

mixture dense enough to be applied easily with a metal trowel (see dilution instructions

above).

First coat: During the application, it is useful to have a light source close to and parallel

to the floor. Be careful, however, that this doesn’t dry out the material too much before

applying the final coat. Spread the first coat evenly over the entire surface, finishing,

obviously, at the doorway. You will need approximately 650-700 g of material per

square metre. Let it dry until the next day.

Colouring: If you have pre-coloured material, it will be much simpler to apply the

second and third coats. If you must add colour to the material, there are three

possibilities: 1) Colour the material with powder colourants before adding the water.

You must first establish how much colourant is needed to obtain the colour you want to

achieve. 2) Colour the white material after you have mixed it with water. You still must

do colour tests beforehand to be sure of the exact weight of liquid colourant you will

use. You can prepare toners ready to be mixed. 3) Tint all the water that will be used in

the tinting process. Solutions 2 and 3 are the more practical. In all the cases, the

colourant must be one which is resistant to alkaline environment such as that of

cement.

Second coat: Mix up enough material for the second coat (650-700 g. of powder per

square meter) of PASTELLONE FINE, and using a metal trowel, start applying it. Have

February 24 TDS PASTELLONE 4 of 8

a clear plan of how you are going to apply it in 40-50 cm strips, beginning at the point

farthest from the door. Be careful to apply it uniformly and smoothly.

Third coat: After you finish applying the second coat, you’ll have time to prepare the

material for the third coat. Note that the third coat can be applied with the same

material as the second one. It is difficult to give precise instructions on how long to wait

before applying the third coat because it depends on the air temperature and humidity.

In general, the moment is right when you can comfortably step on it, which would be

after 25 minutes or up to an hour. It is recommended to go barefoot or wear socks that

won’t leave their imprint on the material. Apply the third coat with the metal trowel as

you would a normal MARMORINO but pressing less since you can make it smoother

the following day using the sanding machine or sandpaper. You will need approx. 250

g/sqm of dry product for this coat. Note that if your PASTELLONE is tinted white or in a

light colour, it is preferable to use our BIANKO TROWEL, a special titanium trowel that

doesn’t leave any dark mark. If you want to make a smoother finish at this stage, you

can complete the whole floor and then, when you can step on it, come back using a

spray bottle with water and go over it again with the trowel, working a small area at the

time. Spray the water and polish using both a metal trowel and a plastic trowel or,

better, using the BIANKO trowel. You will notice that on the floor, you don’t need to

finish it as smooth and polished as you would on a wall. Besides, it is not possible to

return to polish it after 10 or 15 minutes, as you do on a wall. BE CAREFUL NOT TO

LEAVE DROPS OR EXCESS OF WATER ON THE FLOOR OR THEY WILL LEAVE

LIGHTER MARKS.

Polishing: The day after, the floor can be sanded with a sanding machine. This

treatment is done to make the surface smoother and to increase the movement of dark

and light marks. A P80, P100 or P120 paper can be used. The sandpaper does not

scratch the surface since it is very hard, but just polish it.

For a plain finish: The easiest and fastest way to polish PASTELLONE requires the use

of a sanding machine with disks of metallic mesh, P100. In this case, you can apply the

last coat without pressing too much, just having care to make the floor quite even.

Sanding with the metallic disk helps make the surface smooth also if the last coat was

not very well done and homogenizes the surface. This application method reduces the

working times and results in a more even finish.

For a shaded effect: If you want to have more movement you can apply one or more

layers of a coloured solution. After the polishing phase is completed, prepare our

UNIVERSAL PRIMER diluted 1 part of primer and 18/20 parts of water. Tint it in the

needed tone and, after making a proper test, apply this solution all over the floor using

sponges or better normal clothes. In this way, where you leave a more tinted solution

you get darker areas, creating “shadows of colour”. Please, be careful to make tests

before tinting the floor and note that usually one single layer is not enough. To get a

harmonious effect you must apply two or more layers.

PASTELLONE with aggregates: Our PASTELLONE can be coloured naturally with

small stone chips and marble powders. Not only these aggregates will convey more

depth and add to the natural beauty of the finish, but will also make it harder. You can

add fine powders, starting from 0.7 grain size up to 1.8 mm stone chips of different

shades to the usual PASTELLONE material, and colour the finish without a drop of

February 24 TDS PASTELLONE 5 of 8

colourant paste. It is important to follow the granulometric curve of the aggregates,

which should be complete, starting from 0.7 grain size (the grain size of PASTELLONE

Medium), up to the desired max chip size. In this technique, PASTELLONE MEDIUM is

used for all the three coats, and the aggregates are added to the material used for the

second and third coats.

• For aggregates of 0.7-1.2 mm, you can incorporate them up to 25% of the

total weight.

• For aggregates ranging from 0.7-1.8 mm, they can comprise up to 30% of the

total weight. Ensure a roughly even ratio between the 0.7-1.2 mm and 1.2-1.8

mm sizes.

• When using powders finer than 0.7 mm to colour the finish, limit their addition

to no more than 5% of the total weight. If you opt for these fine powders, avoid

combining them with larger grain-size aggregates.

Exceeding these quantities can disrupt the balance of the Pastellone formulation,

leading to application issues.

The application technique is the same as for a plain PASTELLONE finish, with a few

exceptions: Start applying the 3rd coat as soon as you can safely walk upon the 2nd. If

you wait too long, the surface will be too hard, and the aggregates of the third coat

won’t be able to penetrate in the 2nd During the third coat, every completed 2-3m2, go

over the surface again, spraying water and passing the trowel over the surface to close

the pores. Before polishing, fill the holes with some PASTELLONE material.

The polishing must be done starting with a 40 or 60 grit sanding disc, the surface being

very hard.

Warning: Create an environment with the right humidity because the slower the

material dries, the stronger it becomes. The floor shouldn’t be walked on for several

hours and in any case should be protected until you apply the final protection. Without

the final protection, the floor can always be easily stained.

* Notes on substrates:

ON NEW CONCRETE SCREED: If you are working on a new concrete surface, be

sure that it is at least a month seasoned and that it is completely dry. It’s possible for

cracks to appear in new concrete in the first 3 weeks after laying the concrete.

ON PLYWOOD PANELS: Application on plywood floors is possible, provided that the

panels are solidly glued and that the floor substrate is stable. Do not apply on plywood

panels that have been screwed and not glued. Screwed panels tend to vibrate. Any

movement of the plywood floor will cause cracks on the PASTELLONE finish.

IN SHOWERS: This material can be used in wet areas such as shower walls and

steam-bath walls.

ON CERAMIC TILES: Apply one coat of GLP (Gap Levelling Plaster) within the tiles’

gaps, and, when this dries, apply a second coat of GLP all over the floor. This method

doesn’t require you to abrade the ceramic tiles since it is very adhesive, and it fills the

gap among the tiles with a single application, as it is a plaster that has no shrinkage.

SUBSTRATE WITH CRACKS: On a cement screed, consider whether the cracks are

due to the curing process and not due to settlement movements. If they are due to

February 24 TDS PASTELLONE 6 of 8

settlement movements: First, apply a narrow fiberglass mesh (7-8 cm) along the crack,

and fix it to the surface using a fibrous plaster, like our ANTICRACK. Then, use 100

cm-wide FIBERGLASS mesh (available at STUCCO ITALIANO), placing them side by

side without overlapping them, covering the whole floor. If the floor surface is a new

screed, you can fix the wide mesh bands to the floor with the first coat of

PASTELLONE. On the contrary, if the floor is covered by tiles or marble, you should

first fix the mesh with a layer of highly fibrous and adhesive plaster, such as our GLP.

When you apply PASTELLONE over a tiled floor, you should pay particular attention to

cracks. Sure enough, tiled floors often present cracks. Nevertheless, they are hardly

noticeable, as the crack rarely breaks the marble or ceramic tile. Most often, the crack

will follow the tiles running along their edges. Usually, the operator does not notice it

until the work is finished, when the crack appears clearly over the plaster. The crack on

the tiled floor is hardly noticeable, because it follows the edges of the tiles, and it hides

in their gaps. For this reason, it is advisable to always apply a mesh on all tiled floors

before applying a coating. We especially recommend it when you work on floors

located above the ground floor, which, in a building, is the most stable one.

Tips:

TOUCH-UPS: It is possible to do touch-ups when necessary. To do this, we advise

keeping some of the powder-coloured material (if you had it) in a well-sealed container.

Use a container which is just big enough, so the material is exposed to little air. Doing

this should allow you to keep the material ready to use for many years. Or keep note of

the formulation to tint the flooring plaster, if you were starting from not tinted material.

WORKING IN ADJACENT ROOMS: If you must work in two adjacent rooms, it is

advisable to create a natural break at the doorways. You can’t, in fact, work in 2 or 3

rooms at a time without having breaks. One way to deal with this is to put a band of

metal (aluminium, steel or brass) into the concrete (screed) substrate which will act as

a divider. This band of metal should rise above the surface of the concrete 1.5 -1,7

mm. We use metal blades that are 15 mm high and 3 mm thick, and we fix them after

cutting the screed for at least one third of its thickness, which forces the screed to

convey any movements along this cut without creating cracks in the other areas.

USE KNEE PADS: Whenever applying products on floor surfaces it is advisable to use

knee pads.

BE AWARE OF HEAVY OBJECTS: Dropping heavy objects on the surface can cause

small dents, exactly as happens with wood flooring.

Exteriors: For exterior wall 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

February 24 TDS PASTELLONE 7 of 8

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 INTERIOR: BEESWAX / MINERAL WAX / MARSEILLE SOAP / HYDROCALCE

EXTERIOR: MARSEILLE SOAP / HYDROCALCE

WET AREAS/ FLOOR: PRESEALER FOR PASTELLONE + PU1C / PU2C

FURNITURE: PU1C / PU2C

Interior walls: A protective treatment is optional in most circumstances. It is however

necessary in bathroom walls, kitchen and splashback walls, and a must inside

shower/sauna walls.

Exterior walls: 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. To protect the finish, after at least 72

hours at a minimum of 20°C, proceed with a colourless, penetrating HYDROCALCE,

developed to protect exterior plaster coverings.

Interior floors: A protective treatment is necessary. After 2-5 days (the longer, the

better), you can apply the final treatment which can be done in two ways:

A) With the application of 2 or 3 coats of PU1C or PU2C (single or dual component

polyurethane). This is usually applied with a roller. It can be preceded by a

waterproofing and stabilising treatment made with our PRESEALER FOR

PASTELLONE applied in two coats. This treatment facilitates the application of the

varnish and reduces the absorbency of the floor. After the PU varnish you can apply

two coats of PROTECTIVE WAX. This third step is not necessary but makes the floor

easier to clean.

B) The alternative, Eco treatment is done with ECOTOP, ecological vegetable oil. Pour

it on the floor and spread with a soft, absorbent cloth. Remove all excess by spreading

sawdust onto the whole floor, or by cleaning it with a cloth. Note that, before applying

ECOTOP the floor must be very dry, since the presence of alkaline water could cause

the saponification of the oil, leaving white marks on the floor. After 2 days, apply

MINERAL WAX in a minimum thickness with a trowel or cloth. Keep in mind from the

beginning that this protective treatment will darken considerably the finish, with that

which we call a “wet look”.

Maintenance Clean with non-acidic, and preferably slightly alkaline or neutral, detergents. Some

flooring wax (as PROTECTIVE WAX) can be used time by time into the washing water.
