Introduction: A Cheap and Easy Homemade Paint (una Pintura Barata Y Fácil Hecha En Casa)

La pintura al l�tex m�s barata, en Argentina, cuesta alrededor de 1.17 U$S el litro. La que les
presento hoy cuesta solamente 0.65 U$S, y no tiene nada que envidiarle en cuanto a resultados.

La receta me la pas� un amigo ruso que vive en Argentina desde hace unos 14 a�os.


The cheapest latex paint, here in Argentina, is around U$S 1.17 per liter. That I am presenting today's costs only U$S 0.65, and has nothing to envy in terms of results.

This recipe was handed to me by a Russian friend who has lived in Argentina for about 14 years.

Step 1: Materials & Tools (materiales Y Herramientas)

1) Leche descremada o parcialmente descremada, en cantidad suficiente para los litros de pintura que usted calcule que va a necesitar.
2) Cemento para mamposter�a, 1/4 en volumen respecto de la leche.
3) Recipiente/s de tama�o adecuado.
4) Cuchara de tama�o adecuado.
5) Algo para revolver la mezcla. Puede ser una varilla de madera, un tubo de pl�stico, algo as�.
6) Pincel o rodillo para pintar.
7) Opcional, una gata.

1) Skimmed or partly skimmed milk, enough for the number of gallons of paint you think you'll need.
2) Masonry Cement, 1/4 in volume compared with the milk.
3) Container/s of appropriate size.
4) Spoon of appropriate size.
5) Something to stir the mixture. It may be a wooden stick, a plastic tube, like that.
6) Brush or paint roller.
7) Optionally, a she cat.

Step 2: Mixing (mezclando)

Esto es tan sencillo que casi no requiere explicaci�n.

Agregue el cemento a la leche, aproximadamente una cuarta parte en volumen. Ejm: para 1 litro de leche, 250 cc de cemento. Esta proporci�n var�a de acuerdo al gusto de cada persona. No sea pijotero, eso s�.

This is so simple, it hardly requires explanation.

Add the cement to milk, about one part cement to four parts milk. Example: for 1 liter of milk, 250 cc of cement. This proportion varies according to each person's preference. Don't be stingy, though.

Step 3: Testing It (probando)

Antes de arruinar una pared, es aconsejable probar la consistencia de la pintura. En este caso voy a usar un trozo de madera.

Before you ruin a wall, it is advisable to test the consistency of the paint. In this case I will use a piece of wood.

Step 4: Tests I Did 2 Weeks Ago (pruebas Que Hice Hace 2 Semanas)

Pint� sobre madera, hierro, mamposter�a y vidrio. Todos los resultados fueron satisfactorios. Solo dos manos de pintura cubrieron aceptablemente todas las superficies. Lo normal es dar tres manos.

Hay que tener en cuenta que no me esmer� en obtener un resultado est�tico, solo quise ver si la pintura era efectiva.

I painted on wood, iron, masonry and glass. All results were satisfactory. Only two paint coats covered acceptably all surfaces. It is normal to do three coats.

Keep in mind that I didn't take great pains to get an aesthetic result, just wanted to see if the paint was effective.

Step 5: The Paint, After 2 Weeks (la Pintura, Luego De 2 Semanas)

Yo hice otra prueba como esta hace dos semanas. Pens� que la leche se iba a agriar en un d�a o dos, pero no fue as�. Parece que el cemento es muy alcalino, y las bacterias de la leche necesitan un medio �cido para sobrevivir. De hecho, al mezclar el cemento con la leche se percibe un olor notablemente �spero, lo cual indica que se produce una reacci�n qu�mica. �Qu� piensas t�, NurdRage?

Luego de 4 d�as fui a ver qu� hab�a ocurrido con la pintura, y encontr� que el cemento se hab�a asentado en el fondo del recipiente. Tuve que revolver fuertemente para volver a lograr una consistencia homog�nea a efectos de aplicar la segunda mano de pintura. Se produjo entonces una densa y homog�nea espuma, que sin embargo no me impidi� usar la pintura.

Hoy, dos semanas despu�s, encontr� que esa espuma se hab�a cuasi consolidado en forma de pasta esponjosa y h�meda. Le agregu� un poco de agua para ver si es posible volver a usarla. Tal vez eso sea un indicio positivo. Los tendr� al tanto.

I did another test like this two weeks ago. I thought the milk would sour within a day or two, but it did not. It appears that the cement is very alkaline, and the bacteria in milk need an acidic environment to survive. In fact, mixing the cement whit the milk you smell remarkably sharp, indicating that a chemical reaction occurs. What do you think, NurdRage?

After 4 days I went to see what had happened to the painting, and I found that the cement had settled at the bottom of the container. I had to scramble hard to re-achieve a smooth consistency for the purposes of applying the second coat of paint. There was then a dense and homogeneous foam, which however don't prevented me from using the paint.

Today, two weeks later, I found that the foam had quasi solidified in the form of fluffy, moist dough. I added a little of water to see if I can reuse it. Maybe that's a positive sign. I'll keep you informed.

Perdòn por mi ignorancia pero: el cemento que usa es el mismo de los "pisos de cemento alisado"? Porque si es asì seguramente serviràn los mismos pigmentos que se usan en esos pisos justamente.

Es cemento común, el mismo que he visto que usan para los pisos alisados.

Pero finalmente he llegado a la conclusión de que no es negocio pijotear en pintura, porque es más el trabajo de pintar que el costo de la materia prima. Más vale comprar una buena.

Creo que esto es una solución de emergencia. También la cal sirve.

do you know of a way to add color to the paint?

No, I don't know it.

The farmer barns in our country have been traditionally painted red.

My understanding is that they use to make paint much like you do with milk and lime. Then they added iron oxide (rust) as a coloring agent.

Maybe it is as you say.

I confess that I did not dare to use this paint when I painted some rooms in my house last year. The cost of the paint is inversely proportional to the hours of work to get a good result.

I think that recipe is useful when the aesthetic don't matter.

Why not use white cement in place of lime.... that way you don't need to wait "45 days" for the lime to ferment. here in India, the painters use white cement as a protective coating on plastered walls (applied with a brush) before they use expensive paints

Sorry, you did not understand because I have not been very explicit. No waiting 45 days, the paint is used at the time to do it. Anyway your suggestion is very useful.

Sorry for the misunderstanding..... the comment wasn't directed at you but towards the suggestion of pmartinez which suggested the use of lime in the place of cement to enable using colours as needed...

Hola, mis disculpas, es importante fermentar la cal por unos 45 días, el polvo de cal reacciona con el agua y crea una sustancia pastosa, se usa mas que nada para pintar el tronco de los arboles. Esa sustancia lechosa es a la que me refiero, mi pregunta es, a esa sustancia se puede mesclar con leche y cemento para pintar laminas de zinc.
Gracias

Hi, my apologies for the misunderstanding, Is important to ferment lime for at least 45 days with water, this reaction creates a creamy paste, that can be used to paint, mostly tree. My question is, can this substance be added to milk and cement to paint zinc metal sheets. (old tin roofing )
Thank you"

OK, now Understand. This flaw is derived from the technic impossibility of separate the different previous messages, then each new msg added is sent to all others.
