How to properly prime the car before painting
ePrimer of the car serves as an intermediate coupling link between a metal surface of a body and painting.
Application of primary anti-corrosion primer
It is needed for the following purposes:
- leveling the body surface and filling scratches and chips;
- improving adhesion;
- corrosion protection of a car body;
- prevention of exposure to temperature and atmospheric factors.
Priming a car is a simple task. All the work is quite simple to do with your own hands. All you need to do is carefully read the process and follow all the recommendations.
If you do everything honestly and diligently, you will be able to apply all the layers correctly with your own hands, and the paint on the car will lie nicely and evenly.

Types of soil for cars
Before you start applying soil with your hands on the surface of the car body, you need to choose exactly that composition, which is suitable for your purposes.
You should know, that the market has a large number of similar products. Before you start, you should read this, how many species there are and what each of them is intended for.
so, distinguish between these types of primers for cars:
- acrylic;
- acid;
- epoxy.

Acrylic type is the most common. This is almost a universal ground for the car, which is applied to the body surface before painting for:
- leveling the surface and filling micro-irregularities;
- improving adhesion;
- corrosion protection;
- guarantees of that, that the paint will last long and well.
Acidic soil is a means of chemical protection of the car body from the effects of moisture and salts. It forms a thin film, which prevents corrosion. You need to keep that in mind, that acid soil is a means of primary treatment of the car before applying the secondary layer. Paint is not applied to it under any circumstances. It should be applied in a thin layer, on which the filler is placed on top, and only then - paint.
It is strictly forbidden to use the acid composition together with polyester putty and epoxy primer. In this case, the action of the acid layer is simply neutralized, and it loses all its protective properties.

Epoxy primer is a substance, which protects the car body from corrosion and external mechanical influences. This is due to that, that a strong film is formed on the surface of the car body, on which it is possible to put a paint and varnish layer. Experts say, that the epoxy film is impermeable to water, has heat resistance and durability. Also emphasize the high environmental friendliness of this product - it is made of natural materials.
The disadvantage of epoxy composition is the amount of time, necessary for drying. Epoxy primer dries more 12 hours - this tool is clearly not suitable for quick car repairs.

Another type of classification is based on that, how many components the substance contains. There are 2 types of primers for cars:
- one-component;
- two-component.
One-component materials are ready to use - they do not require prior preparation before starting work, and they do not need to be bred. Two-component materials must be diluted with hardener and solvent before starting work, then they can be applied.
Primers can be sold in metal cans or aerosol cans. Only one-component substances are sold in cans, which can be used. They are very easy to operate, but have extremely low productivity. If a large amount of work awaits, aerosol will not suit you - it is designed to treat local areas of the car body.

Preparing the car
All work with your hands should be performed in a clean dry garage, where there is no dust and dirt. You need to make sure, that it is well ventilated and well lit.. After that, you can start preparing the car:
- Wash the car thoroughly, removing all dust and dirt.
- Get rid of areas of corrosion by grinding areas.
- Degrease the surface with antisilicone.
Windows and all areas, which we do not plan to base, must be covered with paper or polyethylene, fixing them with masking tape. You need to properly protect all rubber gaskets from soil.

Preparation of warehouse and equipment
It is necessary to calculate correctly before the beginning of work, how much material you need to work with your hands. If you do not plan to finish the whole body, but you just want to prepare small local areas for painting, use an aerosol can - it is perfect for such purposes.
If we decide to choose the soil in a metal jar, it should be diluted with hardener and, if necessary, with solvent. How to properly dilute the composition, specified in the instructions, it must be carefully read and carefully follow all the recommendations.
Read the instructions, It is important to know how long this type of soil dries, do you have the right amount of time. The paint is applied only on a completely dry coating.

Features of priming with your own hands
The composition is applied, as mentioned above, aerosol method or brush, roller or air gun. The distance to the treated surface and the size of the torch are indicated, usually, in the instructions.
The primary layer is applied very thinly and applied only 1 once. Secondary — 2 or 3 times. We take breaks between layers 15 minutes, waiting, while the coating dries. You can start something new, when the previous one becomes matte.

The time of complete drying in different mixtures is different - you can find out from the instructions. Once we were convinced, that the drying time is over, you need to start sanding before painting - it is necessary, that the paint lay down in an equal layer. The primer is sanded by hand using sandpaper or with a power tool with abrasive wheels. To prepare the surface for painting as effectively as possible, work in step mode, gradually reducing the grain size of the abrasive. The primer should eventually become smooth, without scratches and micro-irregularities.
For work it is best to use quality tools from well-known manufacturers. Cheap materials shrink after drying, as a result the paint lays down unevenly and peels off very quickly. Therefore it is not necessary to save on a primer for the car.
Conclusion
Priming is an important part of the preparation process before painting a car. It is designed to protect against corrosion, and also for increase of coupling of a paint and varnish covering with a body material.
Applying a primer is a simple process. You can do it yourself, even without the appropriate skills. The main thing is to choose the right type of mixture, properly prepare and honestly work out the right part of the car.
Remember, that the quality of the primer largely determines the durability and aesthetics of painting your car. Be attentive, try not to hurry - in this case you will be able to achieve the desired result.
