Campo dell'invenzione Field of the invention
La presente invenzione si riferisce ad un metodo e kit di preparazione, posa e trattamento di una malta a base di grassello di calce per finiture e rivestimenti. Stato della tecnica The present invention relates to a method and kit for preparing, laying and treating a lime putty-based mortar for finishes and coatings. State of the art
Sono note malte a calce idraulicizzate con additivi. Hydraulic lime mortars with additives are known.
Relativamente al grassello di calce, sono stati eseguiti studi sui fenomeni dell'ossidazione del grassello insieme a un'inerte, sia esso carbonato di calcio, sia esso polvere di marmo o di un cocciopesto di laterizio cotto. Da detti studi si à ̈ appreso che le finiture mediante malte a base di grassello di calce tendono ad opacizzarsi e ad essere aggredite dagli agenti atmosferici degradando le proprie caratteristiche estetiche di lucentezza. With regard to slaked lime, studies have been carried out on the oxidation phenomena of slaked lime together with an inert, whether it be calcium carbonate, marble dust or a terracotta cocciopesto. From these studies it has been learned that the finishes using lime putty-based mortars tend to become opaque and to be attacked by atmospheric agents, degrading their aesthetic characteristics of gloss.
In tempi più recenti si à ̈ ricorso all’uso di resine acrilica miscelate col grassello di calcio allo scopo di rendere più resistente la malta. Tale soluzione però relega il grassello di calce non più al ruolo di legante quanto a quello di carica carbonatica deteriorando le caratteristiche estetiche e di traspirabilità della malta ottenuta. D’altro canto, si sta diffondendo sempre di più la necessità di produrre malte comprendenti componenti completamente naturali allo scopo di preservare la salubrità dei luoghi in cui le malte vengono impiegate. More recently, acrylic resins mixed with calcium putty have been used in order to make the mortar more resistant. However, this solution relegates the lime putty no longer to the role of binder as to that of carbonate charge, deteriorating the aesthetic and transpiration characteristics of the obtained mortar. On the other hand, the need to produce mortars comprising completely natural components is becoming more and more widespread in order to preserve the healthiness of the places where the mortars are used.
Sommario dell’invenzione Summary of the invention
Scopo della presente invenzione à ̈ quello di fornire un metodo di preparazione, posa e trattamento di una malta a base di grassello di calce per finiture e rivestimenti atto a risolvere il suddetto problema della inalterabilità della malta, evitando l’impiego di resine acriliche od altri prodotti sintetici di origine industriale. E’ oggetto della presente invenzione un metodo di preparazione, posa e trattamento di una malta a base di grassello di calce per finiture e rivestimenti, conformemente alla rivendicazione 1. The purpose of the present invention is to provide a method for preparing, laying and treating a lime putty-based mortar for finishes and coatings capable of solving the aforementioned problem of the inalterability of the mortar, avoiding the use of acrylic resins or other synthetic products of industrial origin. The object of the present invention is a method for preparing, laying and treating a lime putty-based mortar for finishes and coatings, in accordance with claim 1.
Un ulteriore scopo dell’invenzione à ̈ quello di fornire un kit di finitura e trattamento di rivestimenti in particolare per realizzare il metodo suddetto. A further object of the invention is to provide a finishing and treatment kit for coatings in particular to carry out the above method.
E’ pure oggetto della presente invenzione un kit di finitura e trattamento di rivestimenti, conformemente alla rivendicazione 10. The present invention also relates to a kit for finishing and treating coatings, in accordance with claim 10.
Le rivendicazioni dipendenti descrivono realizzazioni preferite dell’invenzione, formando parte integrante della presente descrizione. The dependent claims describe preferred embodiments of the invention, forming an integral part of the present description.
Descrizione in dettaglio di una forma di realizzazione preferita dell'invenzione Detailed description of a preferred embodiment of the invention
Il metodo della presente invenzione comprende i seguenti passi: The method of the present invention comprises the following steps:
- predisposizione di una quantità di grassello di calce, - preparation of a quantity of slaked lime,
- eventuale aggiunta di un colorante, - possible addition of a dye,
- aggiunta di caolino bianco in dose preferita tra lo 0.5% e il 2% e dose ottimale dell’1% in peso, - addition of white kaolin in a preferred dose between 0.5% and 2% and an optimal dose of 1% by weight,
- aggiunta di polvere di marmo, preferibilmente Bianco di Verona, o cocciopesto, con preferibilmente, curva granulometrica da 0 a 0,4 mm , con dosaggio di tre parti di grassello e quattro parti di inerte. - addition of marble powder, preferably Bianco di Verona, or cocciopesto, preferably with a granulometric curve from 0 to 0.4 mm, with dosage of three parts of slaked and four parts of inert.
Quando la fluidità del prodotto ottenuto non à ̈ soddisfacente, il metodo comprende un ulteriore passo di aggiungere una soluzione di amido di riso. When the fluidity of the product obtained is not satisfactory, the method includes a further step of adding a rice starch solution.
Quando l'applicazione della malta à ̈ effettuata su un intonaco stagionato, il metodo comprende un passo preliminare di bagnare a rifiuto l'intonaco prima della stesura della malta ottenuta ai passi precedenti. When the application of the mortar is carried out on a cured plaster, the method includes a preliminary step of wetting the plaster to excess before spreading the mortar obtained in the previous steps.
Si preferisce che una prima mano di malta sia grezza e venga stesa mediante spatola di acciaio. It is preferred that a first coat of mortar is rough and is spread with a steel trowel.
Quando la prima mano ha aderito in modo sufficiente, si procede con la seconda mano controllando che lo spessore sia nell'ordine del millimetro. When the first coat has adhered sufficiently, proceed with the second coat, checking that the thickness is in the order of one millimeter.
E’ consigliabile che l’applicazione mediante spatola di acciaio venga eseguita a mezzo di una lavorazione circolare fino al raggiungimento della compattezza e lucidatura necessaria. It is advisable that the application with a steel trowel is carried out by means of a circular process until the necessary compactness and polishing are achieved.
Vantaggiosamente, l’impiego di caolino nelle suddette percentuali garantisce un suo comportamento da serbatoio di acqua conferendo alla malta una buona scorrevolezza. Invece, a malta asciutta, il caolino partecipa a rendere impermeabile il manufatto, perchà ̈ quando entra in contatto con l'acqua si gonfia, sbarrando le porosità dell’intonaco. Advantageously, the use of kaolin in the above percentages guarantees its behavior as a water tank, giving the mortar a good flowability. On the other hand, when the mortar is dry, the kaolin participates in making the artefact waterproof, because when it comes into contact with water it swells, blocking the porosity of the plaster.
Il metodo, successivamente, comprende un ulteriore passo di applicare, per esempio mediante pennello morbido o spugna, una soluzione di acqua saponata al 25% ed un altro passo di lucidare l'intonaco ottenuto mediante detta spatola di acciaio, quando esso à ̈ ancora fresco. Questi ultimi due passi di applicazione di acqua saponata e di lucidatura possono essere ripetuti più volte in successione. Vantaggiosamente, gli acidi grassi contenuti nel sapone, preferibilmente di Marsiglia, reagiscono con la calce fresca formando i cosiddetti saponi calcarei o idrossido di calcio, conferendo all'intonaco caratteristiche di idrorepellenza. The method subsequently includes a further step of applying, for example by means of a soft brush or sponge, a solution of soapy water at 25% and another step of polishing the plaster obtained by means of said steel spatula, when it is still fresh. . These last two steps of applying soapy water and polishing can be repeated several times in succession. Advantageously, the fatty acids contained in the soap, preferably from Marseille, react with the fresh lime forming the so-called calcareous or calcium hydroxide soaps, giving the plaster water-repellent characteristics.
Al termine di detta operazione di lucidatura, i metodo prevede un passo di tamponare mediante talco, l'intonaco ottenuto quindi una ulteriore lucidatura mediante spatola e una operazione di lucidatura mediante panno morbido. Tali successione di operazioni può essere ripetuta più volte. At the end of said polishing operation, the method provides for a step of dabbing with talc, the plaster obtained then a further polishing with a spatula and a polishing operation with a soft cloth. Such succession of operations can be repeated several times.
L’operazione di tamponatura à ̈ ottenuta, preferibilmente, racchiudendo del talco in un tessuto di opportuna larghezza di maglia e tamponando l'intonaco. The plugging operation is preferably obtained by enclosing talcum powder in a fabric of suitable mesh width and dabbing the plaster.
La funzione del talco consiste nel creare una pellicola superficiale che frena l'evaporazione dell'acqua, permettendo alla calce di ossidarsi con il carbonato di calcio per un opportuno tempo. Inoltre, vantaggiosamente, l’operazione di tamponatura mediante talco conferisce una particolare resistenza alla superficie dell’intonaco, in quanto, essendo un silicato, si combina con la calce e cementifica conferendo all’intonaco ottime caratteristiche di traspirabilità . The function of talc is to create a surface film that slows the evaporation of water, allowing the lime to oxidize with calcium carbonate for an appropriate time. Furthermore, advantageously, the plugging operation using talc confers a particular resistance to the surface of the plaster, since, being a silicate, it combines with lime and concretes giving the plaster excellent transpiration characteristics.
Infatti, seppur il talco sia di per sé un materiale morbido, applicato come descritto, interagisce con l'intonaco portando a risultati sorprendenti in termini di durezza e durevolezza dell’intonaco così ottenuto. In fact, although talcum is in itself a soft material, applied as described, it interacts with the plaster, leading to surprising results in terms of hardness and durability of the plaster thus obtained.
Inoltre, sono presenti nel talco, gli alluminati, il titanio, il manganese ed elementi che seppure in modo blando interagiscono lentamente con l'intonaco conferendo un aspetto gradevole. In addition, aluminates, titanium, manganese and elements are present in talc which, albeit in a mild way, interact slowly with the plaster, giving a pleasant appearance.
Secondo una variante preferita del trovato, il metodo comprende una ulteriore operazione di encausticatura, (per interni) preferibilmente realizzata a distanza di qualche giorno dalle precedentemente illustrate operazioni. According to a preferred variant of the invention, the method comprises a further encaustication operation, (for interiors) preferably carried out a few days after the previously illustrated operations.
In tal modo l'intonaco ottenuto possiede una protezione adeguata per resistere alle peggiori condizioni ambientali. In this way the plaster obtained has adequate protection to withstand the worst environmental conditions.
Preferibilmente, detta operazione di encausticatura à ̈ realizzata mediante una mistura di Preferably, said encaustication operation is carried out by means of a mixture of
- 120 parti di cera d'api - 120 parts of beeswax
- 80 parti di cera carnauba - 80 parts of carnauba wax
- 30 parti di essenza di trementina, - 30 parts of turpentine essence,
inoltre, l’operazione à ̈ condotta a supporto completamente asciutto, cerando a caldo e facendo in modo che la cera penetri il più possibile nel supporto. furthermore, the operation is carried out when the support is completely dry, waxing while hot and making sure that the wax penetrates as much as possible into the support.
L’operazione può essere completata, preferibilmente con una operazione di lucidatura mediante un panno morbido sino a ottenere la lucentezza e la protezione voluta. The operation can be completed, preferably with a polishing operation using a soft cloth to obtain the desired shine and protection.
Si preferisce che le varie mani di intonaco vengano date quando la precedente mano à ̈ ancora fresca. Se ciò non à ̈ possibile, à ̈ importante à ̈ che il materiale steso sul muro si presenti il più ruvido possibile, cosa che permetterà successivamente di riprendere il lavoro dopo aver bagnato abbondantemente il supporto. It is preferred that the various coats of plaster are applied when the previous coat is still fresh. If this is not possible, it is important that the material laid on the wall is as rough as possible, which will allow the work to be resumed after having thoroughly wetted the substrate.
Una variante preferita del trovato prevede che, quando non sia possibile stendere tutte le mani in successione fin tanto che la mano precedente à ̈ ancora fresca, l’intonaco venga isolato con un primer in modo da rallentarne l'essiccazione e renderlo uniforme negli strati stesi per evitare che, quando si bagni, traspaiano tracce sottostanti dovute al diverso assorbimento dei materiali usati nel supporto. Si preferisce che il primer sia di tipo all'acqua biologico e mai a base di solvente sintetico. A preferred variant of the invention provides that, when it is not possible to apply all the coats in succession as long as the previous coat is still fresh, the plaster is isolated with a primer in order to slow down its drying and make it uniform in the layers. spread to avoid that, when wet, traces underneath show through due to the different absorption of the materials used in the support. It is preferred that the primer is of the biological water-based type and never based on synthetic solvent.
Vantaggiosamente, al di là dei dosaggi ottimali su esposti, la poca acqua nell'impasto, la soluzione di acqua e sapone, e il talco applicati come descritto garantiscono un risultato finale piacevole quanto duraturo, oltre che garantire una giusta tempistica di lavorazione, consentendo la realizzazione di una finitura completa di circa 20 mq giornalieri per persona. Advantageously, beyond the optimal dosages described above, the little water in the mixture, the solution of water and soap, and the talc applied as described guarantee a pleasant and long-lasting final result, as well as guaranteeing the right timing of processing, allowing the realization of a complete finish of about 20 square meters per day per person.
E’ importante sottolineare che l'operazione di tamponatura a talco risulta fondamentale per rendere il manufatto durevole, impermeabile oltre che accentuare le sfumature del manufatto sopratutto nei controluce al sole e a quelli dovuti a lampade a bassa intensità di luce. It is important to underline that the talc buffering operation is essential to make the product durable, waterproof as well as accentuating the nuances of the product especially in backlighting against the sun and those caused by low intensity lamps.
Secondo un altro aspetto del trovato, nel caso del dosaggio con la polvere di marmo, la mistura può essere conservata per mesi, se ben sigillata dentro contenitori preferibilmente di plastica, dopo aver coperto la superficie della mistura con un velo di olio enologico che dovrà essere asportato prima di utilizzare il prodotto, oppure mescolando l'impasto con l'1% di acido salicilico e ricoprendolo con una soluzione di sapone di Marsiglia.
