Why do you need zinc primer - useful recommendations for selection and use

The key to successful painting of your car lies in high-quality priming, which has been proven by many years of experience of specialists. The soil acts as a foundation on which paint is applied from the factory or during repairs. Beginning craftsmen sometimes make a lot of mistakes, not having the proper professional skills and not knowing about the basic properties of primers and the peculiarities of interaction with them.

Nowadays there are a large number of brands from famous brands on the market, but we decided to focus on the most popular and convenient products - aerosol cans. As a rule, the composition of such a product is represented by a one-component leveling primer. It is most convenient in cases where the finished part has parts punched under the ground. Saving time and minimizing space occupied are the main advantages of these soils. After application, all you have to do is wait about 10 minutes and then sand until perfectly smooth.

We have selected for you the top 5 primers for cars in cans, based on functionality, application, price and customer reviews.

1. Preparatory step - at this stage it is necessary to clean the surface from dust, dirt and other residual materials. In addition, all uneven areas should be repaired, but this is a relative task. You should not be careless about this stage, because it will determine how long the mixture will last on the surface.
2. Studying the components - before use, you need to familiarize yourself with the composition of the soil. Do not forget that the instructions indicate exactly how to begin the application stage.

Application – after the preparatory work, you can begin application. If you apply the solution in two layers, do not wait for the first to dry - immediately start the second.

What is oxygen primer for a car?

An acid-based primer is a special primer that comes in cans or containers with liquid. The main application is to improve adhesion and anti-corrosion protection.

The product is suitable for treating car bodies and is used as an initial layer.

It is impossible to apply a paint coating or epoxy composition over this product, since additional painting suppresses the acidic properties of the primer.

Application methods

Acid primer can be applied using several methods and tools:

1. Simple brush.
2. Spray gun.
3. By lowering a metal product into a solution.
4. Electrical spraying.
5. Using electrodeposition technology.

In everyday life it is customary to use the first 2 tools. Immersion technology is used in factories.

Is it possible to apply paint to acidic soil?

Experts do not recommend applying paint over a layer of one-component acid primer. Otherwise, the components may cause a change in the shade of the paint due to the action of the yellow pigment.

Zinc-based primer - features, properties, application details

Corrosion is a problem that almost every motorist faces. Even the slightest scratch on the body can be its source, so the issue of protecting metal from rust development is always relevant. To solve this problem, you can buy a zinc primer, the price of which is quite affordable. The product will help stop the destruction process, extend the life of the car and maintain its aesthetic appeal.

What is zinc primer?

Zinc primer is also called liquid zinc, which is used to cold process a metal surface. The texture of the substance resembles car paint, and the composition includes about 95% fine zinc, auto varnish and solvent.

The product is available in various forms, which allows the motorist to choose the most suitable option for him. It could be:

• jar - for use you will also need to buy a solvent for dilution, and in some situations - a hardener;
• spray cans - you just need to shake and apply like a regular aerosol;
• auto marker - used for minor areas of damage, for example, when a scratch or small chip appears.

In order for the use of zinc primer to be effective, it is applied to a previously cleaned and degreased surface. If the part is covered with rust or has remnants of old auto enamel, then the area must be thoroughly cleaned using sandpaper, grinding wheels or a special brush with metal bristles, and the dust must be blown off and treated with a solvent. When cold galvanizing new elements, in order to create a reliable protective layer, they are thoroughly washed beforehand.
