The bottom of VAZ-2110: repair. Recommendations and photos

VAZ-2110 is a very cheap and easy-to-maintain car. But one of his main "sores" is the body. Unfortunately, it is poorly protected from corrosion. After two years of operation on it "beetles" are formed. If you ignore the problem further, holes will appear. Rust is formed everywhere: on arches, wings, at the bottom of the doors. But the most vulnerable place in the VAZ-2110 is the bottom. Photo and description of the process of its repair, see further in the article.

Causes of corrosion

The manufacturer does not pay due attention to the anti-corrosion treatment of these machines (as well as sound insulation). This is evidenced by numerous reviews of the owners. But if the noise in the cabin can still be reconciled, then with holes in the floor - no. This is uncomfortable and unsafe. Accordingly, the question arises about the repair or replacement of the bottom on the VAZ-2110. Experts identify several factors that significantly accelerate its wear and tear:

• Weather. Metal rusts on any contact with water, even if it has been painted and treated at the factory. But rain is not the most disastrous factor. More aggressive with respect to the metal are salt reagents, which our road services sprinkle asphalt in the winter. If you often do not wash the bottom of the machine under high pressure, the salt will remain in the most secret places. Further on these areas rust will form, and after a year - through holes.
• Accident. Even with a minor accident, the base layer of enamel and soil is separated from the metal. If the painting was done by unskilled craftsmen, after 1-1,5 years rusty tracks are formed in this place. The same arise if the surface was not prepared for painting properly and poorly cleaned.
• Clogged drainage. Often, repair of the bottom of the VAZ-2110 is required because of clogged drainage holes. The water eventually enters the interior and the trunk. It has nowhere to go - it is absorbed into the factory carpet and soft soundproof material. In addition to corrosion, it can cause a characteristic smell of mold and rot. Also, water is formed and when non-hermetic mats are used. Textiles are very popular now. But not every model delays moisture, because of what it absorbs into the carpet, and then goes to the metal.

Thus, the bottom of the VAZ-2110 undergoes a negative impact on both sides. Plus, it's very difficult to find the source of the problem. Not everyone in the garage has a pit, and to dismantle the salon in order to identify the "bugs" no one will. Drive until the floor is soft as jelly.

Instruments

To perform the repair of the bottom of the VAZ-2110 with our own hands successfully, we will need a welding machine and mask. Electrodes do not work: the metal is very thin, and there is a risk of burning it. Therefore, only a semi-automatic apparatus and a welding wire are used. Also we need a Bulgarian (preferably small ones) and a circle for cutting metal. Among other materials, sandpaper sheets (or a suitable drill bit), primer, paint, anticorrosion, rust converter should be prepared. At the end of the repair process, the bottom of the VAZ-2110 will need to be noisy. But using old material is useless. Therefore, we buy new sheets of vibroplast (preferably 3 mm) and glue it to the restored surface.

Let's get to work. Preparation

So, first we need to prepare the car. We drive him into the garage and dismantle the salon. It is desirable that the room was with a viewing pit. Depending on the scale of the work, we need to remove one or more seats, as well as part of the carpet, which goes to the "top ten" from the plant.

At the next stage, we cut out the decayed parts of the floor with a Bulgarian. Also we cut out that metal, the thickness of which is less than the factory one - after repair it can rust again.

Pay attention, that under the bottom pass fuel and brake tubes, and also an exhaust system. And under the rear sofa is hidden a tank. If major repairs are carried out, all these elements must be dismantled.

Then carefully clean all the seams with sandpaper. You can use a special nozzle on the drill. The remaining traces of rust are processed by a zinc converter. Caution: he is very aggressive. Therefore, we work exclusively in protective gloves. If the scope of work is very large and the bottom of the VAZ-2110 had to be cut almost the entire element, it is important to ensure the rigidity of the body. In the doorways we install spacers made of wood.

Welding works

Bottom welding VAZ-2110 begins with the de-energization of the on-board network. It is necessary to disconnect both terminals from the battery, otherwise you can burn the computer and other important units. Then we connect the "mass" of the welding machine to the bodywork and proceed to work. You can use patches of the appropriate size or purchase ready-made parts of the floor (especially when it comes to thresholds). Welding the bottom of the VAZ-2110 is to restore:

• The floor panels.
• Poperechin.
• Reference platforms.
• Extensions of spars and thresholds.
• Connectors.

All new sheets are gently grabbed from below. The seam should not be continuous, but with a step of 5-6 centimeters. Periodically check the geometry of the body. If you do not take into account this point, after repair, you can get non-closing doors. At the end of the work, the seam can be made already solid. But the repair of the bottom of the VAZ-2110 does not end there.

Finishing

After welding, the seam is scraped off the scale. You can do it with a hammer with a chisel or sandpaper (which is much longer). If the seam is bad, digest the area anew. Next, we clean the metal to shine and provide anti-corrosion treatment. And that the inside did not get water, we use a sealant. It is the sealant that we process all the seams on patches.

What next?

Then we apply the primer and paint. On both sides the metal is treated with bituminous mastic or cane lard. Due to their fatty consistency, these compounds will repel water and prevent it from penetrating inside, to the metal. In addition, it is possible to apply an anti-gravel coating (in case the metal is treated with mastic, and not with fat). After drying the composition, we make the insulation of the cabin. Sheets with vibroplastic should be laid on a clean surface. On the mud, it does not hold. But on sticky mastic will keep to the full. Additionally, the sheet is rolled with a special roller or by hand through rags. Next, you can safely collect the salon and put the seat.

How to extend the life of the bottom?

These tips are suitable for those who have already repaired the floor on the "top ten", and those who still have a live copy. So, the first rule is frequent washing. Typically, car owners pay attention to the upper body. But you need to wash the hidden cavities. Especially it concerns those who live in large cities and exploit the car in the winter. Salted salt does not disappear until it is removed by a powerful stream of water. The next rule is the regular processing of the bottom. Over time, the old anticorrosion is washed away and exfoliated. Once a year, you need to check its condition and, if necessary, renew the layer. If the surface has already appeared foci of corrosion (but not through), we process them with a converter, and then - a thick layer of mastic. As for the rapids, they have drainage holes. Outwardly, they do not make any sense with anticorrosive treatment - the water is inside. Therefore, in dry and warm weather, take a can of "Moville" and pour it through a thin tube (it usually comes complete) inside. After a year, this procedure should be repeated. Only in this way can the bottom and thresholds be protected from rust. If the problem caught you in the winter, you can apply a temporary measure - to clean the rusty surface and apply an anticorrection to the site locally. And already with warming to make processing on all perimeter.

Conclusion

So, we found out how to repair the bottom on VAZ-2110 in garage conditions. Work can be done alone. The main thing is to use a semi-automatic inverter and do not forget about protective measures (mask, gloves). If the work is carried out for the first time, practice first on unnecessary pieces of metal. When welding it is important to ensure the most uniform and uniform weld.
