TOP means for degreasing surfaces before starting treatment
Any surfaces before painting or performing other repair work must be well degreased.
Degreasing is usually understood as the process of removing all types of contaminants - glue, dust, emulsions, grease, remnants of an old paint layer, even the simplest dirt.
Methods and means for degreasing surfaces are varied, and most of them can be easily applied even at home.
Surface contamination can vary greatly in terms of the degree of contamination - with a small amount of impurities it will be only 1 gram per square meter, and with a strong amount, more than 5 grams per square meter.
Whatever the degree, degreasing is required prior to repair work.
If not done, dirt and grease will reduce the adhesion of the finishing material to the surface, which means that the quality of the work performed will be poor. You should not count on the duration of the product's use - it will be quite short. For this reason, the use of degreasers for processing glass, metal, wood, plastic and other coatings is mandatory.
If a person is determined to paint the surface in an apartment, house, and even on For degreasing, use any suitable agent that should be applied to a lint-free microfiber cloth or other suitable material.
This method will definitely not work if you need preparation for painting a car body. Naturally, it is better to trust the cleaning and painting of the car to a professional who will carry out the work with high quality. In certain cases, you can remove the grease film, as well as protect the car body from corrosion with your own hands.
White spirit is intended for the primary treatment of an automobile body, and after that, the application of alcohol in a mixture with an acid of the orthophosphoric type is practiced to remove contamination residues.
The solution should be prepared by combining substances in certain proportions. With this organic type of solvent, you can safely clean car parts, and the composition does not harm the metal surface. The low cost is another bonus.
Some personal vehicle owners replace the solvent with trichlorethylene, but it should not be used on aluminum alloys - there are fire risks.
Acetone, gasoline and other analogues
All the products that are indicated are excellent fat solvents, paints and mastics.
Kerosene and diesel have a fairly dense structure, and they are still difficult to clean, but the composition is also suitable for degreasing. After using gasoline, kerosene, solvent, you will need to use a reinforced sink to eliminate various traces. It is undesirable to use acetone for automotive processing - certain types of it are ways to harm the metal surface.
If we talk about anti-silicone, then it is a colorless liquid, and a remover for removing oil, grease and silicone. This substance is intended to remove dirt from aluminum, steel, stainless steel, galvanized, plastic, and also varnishes.
It should be applied to the surface and then wiped with a dry cloth and paper towels. Work should be done with gloves, a mask, and the room should be perfectly ventilated.
Means for degreasing metal surfaces before painting is an antistatic agent. It is especially effective to do this on plastic, which will attract dust due to the possibility of electrification. It is quite difficult to remove the fatty film, and after processing the place with an antistatic agent, the work will be much easier.
This group of drugs includes detergent chemicals with an alkaline effect. Various types of dirt can be washed, including even grease. They are usually used in a domestic environment. To clean the surface of concrete, plastic for application, it is worth using a roller. Before painting the car, alkalis should be done with great care, and then the surface is thoroughly washed with clean cold water and dried.
Do not allow the application of large amounts of the product and strong foam formation.
Ultrasound and other methods
A new way of surface cleaning - the use of solutions together with baths and an ultrasonic field. This method is suitable for degreasing small parts, which have an uneven surface, have complex bends, and include different mechanisms (for example, watches). Due to the high cost, the method is not suitable for large products. There is a method of electromechanical degreasing.
It should also be carried out in the bathroom, where gas is supplied from the electrodes. The surfaces will be cleaned with chemical solutions in the presence of current. Usually, such processing is used in production, in industry.
Plastics are one of the largest groups of materials that can accommodate various types of plastic. For many plastics, gasoline, vinegar, acetone are perfect - other materials from such substances can immediately become unusable.
Compositions of a universal type are also not always suitable for plastic. For car parts made of plastic, only special products are used that will be sold in appropriate stores and are suitable for rubber and plastic.In everyday life, you can try to apply white spirit to the material. An antistatic agent will be 100% safe, and a large number of products are perfectly degreased using the simplest vodka.
The algorithm for degreasing plastic before gluing is as follows:
What about the rest of the materials?
On the metal surface, in addition to dirt and grease, there is often paint, rust, and also the remains of the sealant. For metal processing, you should choose white spirit, gasoline and acetone.
The procedure is as follows:
- Remove the rust layer, the remnants of the sealant with a grinder, you can manually (sandpaper) or mechanically (grinder), that is, by any method convenient for you (the bath in the house should be treated with a sponge and soda). Large areas should be cleaned with an electric tool.
- Moisten a cloth with solvent, treat the product until it is perfectly clean. If the parts are small, you can only immerse them in the solvent.
- After the ideal area, you can use primers, paints.
Those areas that will not be stained should be covered with double-sided tape.
Now about the wood.
There are products for degreasing and cleaning surfaces made of wood. Before dyeing, they should be cleaned of varnish and paint. To begin with, clean the wood as thoroughly as possible with a metal brush, sandpaper, and a plane.
The latter is used to remove the top layer if the paint will penetrate deeply - with high-quality work, you don't even need to degrease the surface. For wood, special compounds and solvents of a universal type are used, and they are also applied with a roller. After applying the composition, you can easily clean the surface and then start painting.
Acetone, alcohol and any other solvent will be suitable for glass products. Such chemicals will not harm such material.
Before gluing the glass, you can take any universal type solvent.
The choice of degreaser for the materials to be bonded will depend on the specific materials being used. It can be standard household chemicals, alcohol, alkali, organic solvent. Isopropyl alcohol is suitable for rubber. The main thing is not to apply the product to wet surfaces - when in contact with water, most substances will give an unpredictable reaction or become ineffective.
There is nothing complicated in the procedure of degreasing and further gluing, as well as coloring products. You should familiarize yourself with the required information, it is worth buying a good solvent - then all work will be carried out without consequences and with high quality. At the end of the work, a little water is required to drip onto the surface - if the liquid becomes flat and starts to spread, the cleaning will be perfect.
