Removing paint and other methods of cleaning the surface of the car

Thanks to the coloring, the car does notonly a beautiful appearance, but also gets protection from corrosion. An important factor that ensures a high-quality reliable coloring of the machine is the careful preparation of its surface. The given process consists in removal of the damaged layers and clearing of a surface of a rust, oils and fats.

This is necessary in order fora new layer, it held well, which is possible only on the cleaned surface. On the old paint quickly and easily will exfoliate. To clean the car from old layers, rust and grease, paint is washed chemically, besides, mechanical and hot methods are used.

The most unpretentious method ismechanical or manual cleaning using metal stripping brushes, steel scrapers, large sandpaper, grinding stones, etc. Depending on the complexity of the work, one or another tool is used. It should be noted that this method is quite laborious, and if possible it should be replaced by other methods of cleaning. For example, the old paint is washed.

The most productive mechanical methodis sandblasting the surface of the car. Nevertheless, this method gives good results with respect to rust, and the removal of the old paint by this method is not very effective, especially when it remains sufficiently elastic.

Cleaning the surface of the car from the old layers of paintAlso it is made by means of roasting, for this purpose use a blowtorch. The method is quite effective, especially where it is necessary to get rid of thick layers from vast areas. With this method, the paint under the influence of high temperature is partially burned and so softened that it can be easily removed by hand using brushes or a scraper.

And yet this method of cleaning withflame is very time consuming. It is difficult, and sometimes impossible to use when repairing the car to remove the old paint from the skin, as well as plastic parts, because these elements can be damaged.

The best way is to wash the paint orchemical method using a variety of pastes, solvents. As a result, you save time and labor with low material costs. Removal of old layers by means of washing is a process of chemical action on the surface of the car, while swelling and dissolution of the paint takes place. Alkaline washes and paint thinner are used for this method.

In repair shops to remove old layersAluminum is used mainly from the metal surfaces of car parts and aggregates. Flushing paint is done by immersing the elements of the car in a container filled with a solution of caustic soda, heated to a temperature of + 60-70 degrees. Remove the old paint from the body of a car can be by applying a 30% solution of caustic soda with a mild brush. After 12 hours the paint is destroyed and easily washed off with warm water. However, to remove many layers, this procedure must be repeated several times. This method requires a large consumption of soda.

More efficiently, the paint is washed out by means of pastes, which are weak alkali solutions mixed to a viscous state together with mineral and organic substances.

The paste is applied three times to the surface with a brush,making a two-hour exposure after each application, and then washing it off with a jet of water from the hose. Paste helps to "lift" oil and nitrocellulose varnishes, enamels and paints.

Flushing of the paint is also carried out with the help of various liquid and pasty solvents based on organic substances. After applying the solution, the softened layers are removed with a spatula.
