En la cuarta fase se anaden unos tintes al disolvente concentrado, para dar un determinado color. Luego, como se explicara mas adelante, dependiendo del objeto a cubrir, se precisaran una o mas capas de barniz.In the fourth phase dyes are added to the concentrated solvent, to give a certain color. Then, as explained below, depending on the object to be covered, one or more layers of varnish will be required.
Posteriormente, en la quinta fase, se aplica el producto resultante de la cuarta fase se aplica sobre la superficie (mediante una pistola de pintura aerografica) utilizando abierto al maximo o patron de traslapo mmimo del 75%. El paso de producto 1,5 vueltas, a una presion de unos 3 kilos.Subsequently, in the fifth phase, the product resulting from the fourth phase is applied and applied on the surface (by means of an air spray gun) using the maximum or maximum 75% overlap pattern. The product passes 1.5 laps, at a pressure of about 3 kilos.
La sexta fase es la fase de secado, que existen muchas alternativas, algunas de las cuales se mencionaran a continuacion.The sixth phase is the drying phase, there are many alternatives, some of which will be mentioned below.
Asi, se debe permitir que el revestimiento se estire y evapore bien durante 30-40 minutos antes de hornear a 60°C durante 1 hora. Posteriormente se dejara secar al aire durante varias horas. Este secado puede durar hasta 5-10 dias.Thus, the coating should be allowed to stretch and evaporate well for 30-40 minutes before baking at 60 ° C for 1 hour. It will then be allowed to air dry for several hours. This drying can last up to 5-10 days.
Para el secado al aire, se debe dejar 30 minutos en un ambiente recirculante de aire durante 30 minutos, y colocar despues en una zona libre de impurezas y polvo durante varias horas. El endurecimiento total se consigue a los 5-10 dias, pero a las 24 horas ya se puede manipular la pieza.For air drying, leave 30 minutes in an air recirculating environment for 30 minutes, and then place in an area free of impurities and dust for several hours. Total hardening is achieved after 5-10 days, but after 24 hours the piece can be handled.
En el caso que se aplicasen mas de 2 revestimientos o capas de barniz, se debe dejar algo mas de 24 horas antes de manipular, para conseguir un secado mas efectivo.In the case that more than 2 coatings or layers of varnish were applied, it should be left a little more than 24 hours before handling, to achieve a more effective drying.
Si fueran, por ejemplo, necesarias 2-3 capas para conseguir el color deseado sobre el objeto. Asi, se aplicaria la primera capa humeda. Posteriormente se esperaria unos 10 minutos y a continuacion se procederia con una segunda capa que cubriria el revestimiento ya dispuesto sobre la superficie. La segunda capa cubrira el revestimiento y producira un color mas intenso. La segunda capa puede aplicarse un poco mas concentrada, o bien en dos manos cruzadas y finas en la misma capa (igualmente humeda pero mas fina). Si se desea, se puede esta vez abrir un cuarto de vuelta mas el paso de producto.If, for example, 2-3 layers were necessary to achieve the desired color on the object. Thus, the first wet layer would be applied. Subsequently it would wait about 10 minutes and then proceed with a second layer that would cover the coating already arranged on the surface. The second layer will cover the lining and produce a more intense color. The second layer can be applied a little more concentrated, or in two hands crossed and thin in the same layer (equally moist but thinner). If desired, this time you can open a quarter of a turn plus the product step.
