The drying rate of oil paint is more dependent on external factors, ambient temperature, humidity, illumination, as well as its recipe. The paint hardens by evaporation of the moisture (where its not), but because of oxidation of the oil film. Therefore, in order to speed up the drying process of oil paint, it is necessary to accelerate the process of interaction of the paint with oxygen.
To accelerate the formation of persistent oil film, apply the paint with roller or brush on previously prepared surface in a thin layer. Paint dries in approximately 24 hours. If necessary, reprograme or uneven coating repeat the procedure.
To accelerate the oxidative processes in the oil paint film can heat it. For example, many young artists their paintings dry on the radiators. But this is a special case. Just put in a room where there are just painted with oil paint surface heater or heater. By the way, the heating of the oil paint increases its durability and resistance to alkalis, in other words, soap. The only caution - do not leave the heating device unattended, lest a fire.
There are chemical ways to accelerate the drying of oil paints. This addition to paint of the so-called driers – drying. Add them in small quantities (in accordance with the instructions on the package) to a jar of paint and mix thoroughly. The driers allow to dry painted surface much faster and do not affect the quality of oil paint. In General, as experts recommend before you buy oil paint, read everything that is written on its packaging. A good oil paint contains no less than 10 components.
Oil paint is a mixture of pigments, fillers, and drying oils, can be prepared from natural oils, or artificial substitutes. Oil paint is used for painting wooden and metal surfaces, walls, roofs and floors. When painting, the paint film protects the surface from penetration of moisture vapor. Therefore, metal pipe and construction of buildings are often painted with oil paints, selecting a color to match the main color of the room.
Advice 2: How to quickly dry the paint
When carrying out repairs in the apartment, people can not do without the paint work. And any paint even the best quality have a smell that you want to quickly get rid of, especially if you have a lot of time in the room. It is necessary to dry the ink, which is very difficult when it is made oil-based. To speed up the drying you can use in several ways.
You will need
- -the desiccant;
- construction Hairdryer;
- -infrared heater.
This problem in front of you will not even if you replace long drying oil alkyd paint. A good quality enamel dries in a few hours, maximum a day and a half. When purchasing paint, please note that it says on the tin: there is information about its drying time. Although, of course, the manufacturer indicates this time without humidity correction and temperature.
If you decide to use oil paint, purchase and desiccant – catalyst for the oxidative polymerization. This composition added to the paint specifically so that it quickly dried up.
It is not necessary to paint the cold surface at low temperatures. The paint in these conditions, thickens faster, bad apply and longer to dry. Before application warm the room.
The paint would dry faster, apply a thin layer with a roller or brush. If it turns out that the paint shines through the surface, the next day repeat the procedure.
To the oxidation process of the oil film were faster, provide fresh air into the room. Well, if he's going to circulate, so you can turn the fan on or to organize a draft.
Paint dries faster at elevated temperatures and reduced humidity. For oil paint high temperature even recommended as a coating, dried at room temperature, has a low hardness and water resistance, is rapidly destroyed under the influence of alkalis.
Try to use for drying paint heat gun. It has a special mode for this. About conditions you can read in the passport of the device. But to drastically change the temperature of the air or too to bring the dryer to the painted place in any case should not be, otherwise the paint can crack.
If you painted and want to dry small items, you can try to put the battery of Central heating or even dry in the oven at a temperature not exceeding 60 degrees.
The heater, which is based on infrared radiation, is also great for solving your problem, because the infrared rays freely penetrate through the layer of paint. And thus, it heats up from the inside. The solvent, which is in its composition from the inner layer passes into the exterior, the paint spreads on the surface and dries faster.
