When a car gets into an accident, the bumper is almost always the first to get damaged. This body part takes on the results of the driver's carelessness, and therefore often cracks or falls apart. That is why motorists are often forced to engage in repairs, but it is still not so difficult to carry out which. Using the example of the popular Daewoo Matiz car, you can consider how do-it-yourself repairs are carried out at home.

Before starting repair work, it is necessary to dismantle the bumper from the Daewoo Matiz, clean it from dirt and dust, and inspect the severity of the damage. Damage can be roughly divided into three degrees of complexity:

  • Lungs - scratches, only the paintwork is damaged;
  • Medium - has one or more through cracks;
  • Heavy - Whole pieces of plastic have come off.

In the latter case, it is best to entrust the repair to qualified specialists who can return it to its previous appearance. In the first two cases, preparatory repairs can be carried out independently, after which they can be given to specialists for painting.

To repair moderate damage to the Daewoo Matiz bumper, you may need the following simple tools and materials:

  • Sanding paper of different grain size;
  • Grinder with grinding wheel;
  • Staples for a construction stapler;
  • Soldering iron;
  • Putty for plastic products;
  • Rubber spatula.

Existing cracks are fixed and sealed with heated staples from the inside. In this case, it is necessary to pay attention to the joining of the seam. The fastened seam should not violate the previous geometry of the part. It is recommended to solder the staples at a short distance from each other. The shorter the distance, the more securely the repaired site will hold. The optimal distance will be 5-10 mm from one bracket to the next.

On the outside of the bumper, the crack is cleaned from the old paint with a grinder to the plastic itself. For this purpose, you can use a special paint stripper. Work with such a liquid should be extremely careful so as not to damage entire sections of the bumper. After cleaning, the seam must be soldered with a soldering iron and sealed with putty. When applying the putty, you need to try to restore the previous shape as accurately as possible.

Next, the seam is sanded to an ideal state, after which it is blown with compressed air to remove dust from putty and plastic.

After purging, the bumper is checked for defects. In places of an uneven layer of putty, the procedure for applying it is repeated, followed by grinding.

When the surface at the crack site has been brought to an ideal state, a 3-layer primer is applied to the bumper. After applying each layer, he is given time to dry. After the next layer dries, it is sanded with fine sanding paper.

Once the primer has been applied and sanded, you can give it to a professional to paint or do it yourself with a paint spray gun.

If the damage of the third degree has small areas, and the pieces of the Daewoo Matiz bumper that have fallen off are not lost, then the repair procedure is similar to that described above. The most important thing in this case will be the correct fixing of the fallen piece in its place without distortions and other irregularities.

It is best not to get into such situations, drive carefully and watch the movement. But if damage happened, this problem can be solved using the above written material.

Often in the traffic flow you can find a car with a cracked or deformed buffer. What can you do, no one is safe from unsuccessful parking or a minor accident. Nevertheless, this is not a reason to continue driving a car that has lost its "shiny" appearance - there is a practical experience of restoring the original state of this element.

The external plastic components are mainly made of thermoplastic plastics. The technology for restoring such products is based on welding, it is this technology that allows you to get rid of through cracks and even recreate broken fasteners. Actually, the procedure is not much more complicated than preparing and spray paint damaged area of ​​the car body.

Some car enthusiasts assure us that we repair the bumper with our own hands using metal brackets. But the experienced car owner knows that like is treated like this, that is, repair plastic rods are used for soldering. Their composition, color and profile are different; the required core is selected according to the marking on the buffer.

Making the right choice means guaranteeing a high-quality repair, because the mismatch of materials will significantly reduce the life of the automotive element. To find out what the cracked bumper is made of, it is enough to carefully examine the inside of the part. Depending on the marking, appropriate conclusions are drawn:

  1. PP - polypropylene base.
  2. ABS (GF, PAG 6) are hard plastics.
  3. PUR - polyurethane.

Plastic welding requires high temperatures, for example, 400-450 ° C is suitable for propylene, and 500 ° C is necessary to restore an ABS structure. Many car owners will learn how to repair a bumper with their own hands in a video where craftsmen use an ordinary 100 W soldering iron.

You can also restore a damaged part using pieces from a bumper with a similar marking. They are cut into strips 8 mm wide for PUR, and 4-5 mm for polypropylene.

Almost any breakdowns are treated by welding, even broken parts are reanimated. However, no one canceled the economic feasibility of such work, because the restoration of numerous defects can hardly be called justified. The cost of a complete restoration and staining will be more expensive than a new buffer.

Certain tools are required to complete the repair. These can be both ordinary household appliances and professional tools. The ideal kit includes the following items:

  • Orbital sander or sanding block.
  • Grinding wheels of various grain sizes.
  • Mini drill like Dremel or drill.
  • Clamps and rubber spatula.
  • Soldering iron and hair dryer.
  • Metallic tape.

Of the materials for restoring a cracked buffer, you may need:

  • Putty and primer.
  • Brass mesh for crack reinforcement.
  • A can of paint or a can of paint.
  • Plastic repair rods of the required configuration and composition.

The damaged part must be dismantled in order to eliminate, firstly, excessive stress in the crack area. Those who have already done such work will say that now we clean the bumper and only then repair it with our own hands.

The cracked parts fit together. For reliability, they are fixed with metal tape from the outside of the part. If the breaks are quite significant, then clamps will be needed to clamp the edges of the cracks. Their number depends on the complexity of the repair.

When restoring PP-based parts, the reinforcing mesh is not used. The process begins with the fact that a nozzle with a nozzle with a diameter of 5-7 mm is installed on the hair dryer. In the future, work is carried out according to the following points:

  • On the inside of the buffer along the crack joint, use a Dremel mini-drill to make a groove for the plastic rod.
  • Using a hair dryer, melt and place the repair rod into the prepared groove.
  • Clean the front part of the bumper with an orbital sander with P240 attachment and repeat the welding procedure similarly to the operation on the inside.
  • Grind the cooled seam from the outside with a nozzle with the same grit P240, then remove dust from the surface.
  • Even out irregularities with a special putty for plastic, try to keep the layer as small as possible.
  • Dilute the primer with solvent 3: 1 and apply two coats to the degreased surface. Drying time for the first layer is 15 minutes.
  • Apply a developing layer in a contrasting color, followed by sanding with a disc or sandpaper with grit P800 and P1000.
  • Eliminate the detected defects with a nitro putty followed by sanding with P1000 sandpaper.
  • Remove dust with a damp cloth and degrease the part, then paint plastic decorative paint with overlapping borders 50-100 mm. Apply the paint in 3-4 coats with intermediate drying cycles.

Anyone who is interested in how to properly repair a bumper in a video with their own hands should take into account an important detail. 30-40 minutes after applying the last layer of paint, the part should be varnished. Thus, we get a flawless appearance of the repaired part. Do not forget to follow a few simple rules:

  • You should try to apply a minimum layer of putty.
  • Take a temporary pause for complete hardening of the putty layer.
  • To process the putty area with a grinding wheel or sandpaper with grit P800, and then - P1000.
  • It is desirable to apply a developing layer of primer.

In the case of a polyurethane buffer, the preparatory stage in the form of grooving work is excluded. A brass reinforcing mesh is applied to the crack; steel is not recommended for use, because it is prone to corrosion. Alternatively, stapling staples can be used every 10-20 mm. They are recessed into the body of the part across the seam, it is imperative to make sure that the bracket does not go through the part.

Further, the repair technology does not differ from the restoration of a polypropylene part. Wire mesh or staplers should be sunk into the plastic. Only after that, the seam is filled with repair plastic and soldered from the opposite side. Some important points of technology should be taken into account:

  • It is necessary to solder the mesh or staples carefully so as not to overheat the plastic, otherwise it may deform from the opposite side.
  • For a complete DIY repair of a polyurethane bumper, the width of the reinforcing mesh should be 15-20 mm.
  • It is better to press in the mesh or staples with a flat object.
  • If the legs of the staples pierce the plastic through and through, then they should be shortened using side cutters.
  • For the convenience of working with metal elements, you can use tweezers.
  • To prevent the new enamel from peeling off, it is necessary to grind the paint over the entire plane of the part.

Puttying and painting are performed in the same way as described above - according to the traditional scheme. Repair work on the restoration of the buffer can be combined with painting the car , so the consumption of materials will be more rational. It is important to determine in advance the feasibility of carrying out restoration work. If there are significant costs in the future, then it is better to buy a new part.

During operation, the body of Daewoo Matiz is exposed to road dirt and debris, which damage the paintwork. Parking in cramped conditions sometimes leads to breakage of the car's lining elements. The front part is most susceptible to such defects, therefore, before carrying out cosmetic repairs, the owner is faced with the question of how to remove the front bumper on the Daewoo Matiz.

To perform this procedure, you will need:

  1. Standard jack and wheel wrench.
  2. Stops (metal tripods or bricks with a wooden spacer).
  3. Phillips screwdriver.
  4. A set of wrenches or sockets.

Before starting work, Matiz is installed on a horizontal surface with a solid base. Then you should de-energize the electrical system by removing the ground wire terminal from the negative pole of the storage battery. Removal and installation of the cladding can be performed by one person. Further actions are performed in the sequence given below:
