Each car owner faces the need of a vehicle's shlatting, if it fell into an accident, he received dents or simply formed rust on the body. Shpocking is an integral element of car body repair. This is a complex and time-consuming procedure to learn. Skills and skills come with experience. Only a person who knows his business can achieve the perfect result. It is worth noting that the putty is the most thick finishing layer of the automotive body, since there is a sufficient material for aligning the surface. And, the smaller will be a layer, the less after that it will have to grind the surface of the car.

Types of automotive spacure

Nowadays there are several velocities for automotive putty. Each of them complies with certain requirements. First of all, it should have optimal connecting properties with a correct surface.

Secondly, it is necessary that the solution smoothly lay on the body of the vehicle. Third Russian, high-quality putty gives the minimum risk of shrinkage after solidification.

In addition, we should not forget about the nature of the workability of the frozen material. It is important that the putty in the hard state is fragile. Well, in the end, the aligning material you like should be compatible with the applied paint coating.

putty car fiberglass

Puttail with fiberglass, in principle, as any other, created on the basis of a special resin, which gives the plasticity material and takes part in the polymerization reaction. The quality of the putty directly depends on the quality of the resin used for the production of putty. The second component of such a putty is small fiberglass particles acting as filler, as well as the reinforcing option in the process of crystallization of the entire applied composition. It is worth noting that it is with the help of fiberglass during application to the surface the material has a small degree of shrinkage, it becomes very solid and is actually not susceptible to cracking.

Following the advantages, it is necessary to note the disadvantages of putty with fiberglass. This mixture is more complicated by the required form when applied, as a result of which some experience is needed to work with it.

In addition to all above, the automotive putty of this type has a small degree of plasticity, so it is not recommended to be used on the details that are subjected to vibrations and bends. Traditionally, a fiberglass putty is distinguished by the presence of a solvent in its composition, with which it takes the required consistency. It is worth saying that styrene is used as a solvent, mainly takes up to thirty percent of the contents of the packaging content. When it evaporates from the composition, the putty is thickened and hardens. Evaporation is required after applying, but it is necessary to allow it during the storage of the means.

An additional element of putty with fiberglass is a hardener supplied separately from the material, as a rule, in tubes. The purpose of the hardener is mixing with the main composition, resulting in a chemical reaction and crystallization of putty.

automotive spacure universal

For motorists who prefer maximum simplification of repair work, manufacturers have developed universal medium spacities that can be used for starting defect alignment, and for finishing adjustment. Universal putty rolls are applied on a naked metal, a sandy paintwork, the previous layer of putty. "Universal" is well grinding, but according to the final smoothness, it is capable of a little to give up exclusively finishing counterparts.

automotive two-component putty

The most common and frequently used pow papers are two-component pastes, on the basis of polyester resins, among whose advantages are interaction with paint and varnish material, simple treatment, optimal elasticity after solidification, low shrinkage rate. The composition is recommended to apply a thin layer at the finishing stage of irregularities. In addition, acrylic paste copes well with small defects - microcracks, scratches, chips, risks.

Work automotive spacure

To carry out putty work, such tools and materials will be required:

1. Gloves.
2. Putty knife.
   
3. Grinding wheel.
4. Hardener.
5. Solvent.
6. Directly putty.
7. Scroll to remove dirt and paint residues.
8. Sandpaper.

preparation of the surface to shtcock

First of all, it is necessary to align dents, however, make sure that the surface does not get out. Then, clean the plot requiring the restoration from the dust welding and dirt. This can be done using ordinary water or a special wip, which is also able to remove the residues of polishing paste or paint. To eliminate paint from a car body, use the grinding circle.

Then wash the body for a while. To speed up the surface drying procedure in specialized workshops, bleed guns are used, however, with independent repairs you can use the usual household hair dryer.

Already a dry and clean plot we wipe the solvent for degreasing, which will help the putty to sleep perfectly on the surface of the body and not disappear. In order for the zone being repaired exactly, the fat layer is left, wipe the area with the help of the solvent several times.

Next, cover the degreased and purified surface with anti-corrosion soil, which will protect the covered zone from corrosion and rust.

Preparation of spacure

To make a putty, it is desirable to take two spatulas - small and big. The putty itself does not need to take a lot so that later I did not have to throw away. Next, add a pink hardener from the tube in the ratio of 1:20. After that, mix everything as closely as possible until the appearance of a homogeneous mass. It is necessary to do this with a small spatula. The mixture can be considered ready for applying when pink bodies disappear, and the mass will be homogeneous.

Applying spacure

The first layer of putty must be applied as neatly as possible with some effort on the spatula - only then the mass can fill all scratches and surface irregularities. The composition must be distributed by smooth movements. When the first layer is applied, wait a few minutes so that the putty can silence. If in the garage (or in another room where the work is carried out) is quite cool, use the household hairdryer or heater.

It is very important to observe the temperature in the dryer - the surface overheating is extremely undesirable, since the putty can rise. In the same way, we apply the second and all further layers until the surface is aligned to the required thickness, i.e. when the sample surface is the floss of the painted surface. It is allowed that the putty is a little speaking.

When the surface is aligned, it should be sanded. It is advisable to use fine-grained sandpaper, because it cleans smoother and demolides a smaller layer. In coarse areas, it is possible to use the average sandpaper, but then be sure to mark the fine-grained. Grinding will give the opportunity to level the plot. If it is noticeable that in the process putty comes, it is necessary to paint, and the explicit bugs and fuzzing should be cut off with a knife.

finish spacure

Just making sure that the required bodice area is aligned, it is necessary to prepare the final layer. Make it, as a rule, without a hardener. The putty is applied only on a dried surface. Also for this applies a rubber spatula.

The main error of motorists is an independent putty car without surface preparation and pre-grinding of the draft layer. Do not hurry. If the first layer was not normal normally, it is impossible to apply the second.
