How correctly to putty the car? Consumption of putty. Putty for cars

If, due to an accident or for other reasons, you need to put the car up, and you do not want to contact a professional, you need to know a number of nuances. Someone may think that this is too difficult, and some - on the contrary, that there work for half an hour. In fact, it is possible to tell how correctly to putty the machine, very much and very long. But let's talk about the most important.

Stage one: preparation of the car

You probably already know that before you update any surface, you need to prepare it. This is the case. This is done in order to get coverage as high-quality and reliable as possible. The first thing to do is to polish the surface thoroughly and remove any dust. In addition, it will be necessary to degrease both metal and plastic parts. Well, the final stage in this section is the treatment of the prepared surface with anticorrosive primer. Simply put, it's protection against rust. Let's talk about each of the items in more detail, after which you will understand how to properly putty the machine. It is worth noting that the quality of the work plays an important role, therefore, every procedure must be done on conscience.

A little bit about grinding, dust removal and degreasing

So, we do not need to invent a bicycle, so we will use the previous experience of car owners or plants that recommend using P80 abrasive paper for working with metal products. To remove dust, it is best to use blowing guns. Air consumption per minute should be 140-160 liters. Thus, you can save, because most blowers have a flow rate of about 900-1000 liters. And this is a loss of 70% of electricity to the wind. Also, it is not superfluous to say a few words about degreasing the surface. Here you need to pay special attention and choose those funds whose composition contains the least amount of corrosive substances. The reason is that they violate the condition of the polished sections. Well, now let's go directly to the question about the putty. As noted above, there are a lot of nuances.

Car shampoo: general information

We must understand that there is a huge selection of this material. In addition, the putty may be of different types, for example, finishing, roughing, universal. If we talk about the first layer, then it must be performed with a rough filler or a universal one. For this, we need a special rubber spatula. In advance it is necessary to get and hardener, why - say a little later. Please note that during the application of the material to the surface it is possible to shrink it, that is, the appearance of small dents and bumps. In the first case, a tint is necessary, in the second case - cutting with a knife. But this is still far from everything, since then goes zashkukka. Here it is advisable to use fine-grained sandpaper, since it abrades a very small layer of putty, and even cleans an even larger coarse-grained analog. Of course, if there are too rough areas, then we first use medium-grained paper, and then fine-grained paper.

How to putty the car correctly

Now I would like to say a few words about shrinkage during the work. The fact is that it is because of this property that most of the newcomers drop their business half way. In order for this indicator to be optimal, the amount of solvent in the composition should not exceed 30%. At least, so recommends the majority of professionals in this area. If we talk about quality plaster, the shrinkage is not more than 2%. When applying a thin layer of material visually it is almost impossible to determine. For less shrinkage, it is best to smoothly cut the old coating. If this is done abruptly, then instead of 2 microns shrinkage we will get 20, which is no longer a good thing. If you use low-quality solvents and resins, then the possibility of secondary shrinkage is likely.

How to apply mass to the surface

Well, now we'll go directly to the practical part and find out how to properly putty the machine. Before starting, it is necessary to mix the material with the solvent. This should be done until a homogeneous mass is obtained. We will need a set of various spatulas, the kit can be purchased in specialized stores. To the surface was as smooth as possible, you need to do the work quickly, but neatly, overlaying layer by layer. If we are dealing with a large dent, then it needs to be leveled in 2-3 layers. Do not try to do everything at once. It is recommended to use a universal filler. While it will freeze, and this is 15-20 minutes, you can engage in another area of the damaged surface. After the mass has solidified, you can go directly to the alignment, that is, grinding.

Continuing work

It should be noted that after you have practically leveled a deep dent, it is better to use the finish putty. It is necessary to wait for it to dry out, then use sandpaper P240. Since puttying the car must be carefully, then grinding is performed as high as possible. To process it is necessary not only a dent, but also the nearest sites that will allow to achieve optimum result. In order to hide the damaged place, we need to form a smooth transition, and for this it is best to use a fine-grained abrasive. After all this, there is degreasing and, of course, a primer. But that's not all, as there are other problems that need to be addressed - for example, the emergence of strips from the spatula on the surface. Let's see how to avoid this.

We remove the contours from the spatula

First, it's the most important thing: do not try to eliminate the protruding bands before the material is frozen. Not only will you not correct the situation, but you will also make extra depressions. But when the material completely solidifies, it is quite difficult to cut the strip. This will take quite a lot of time and effort. However, there is a period of time when this is easiest to do. Approximately 5 minutes after application, the material becomes like rubber, at this time with the help of a sharp blade or something like that, you can safely cut off all the bands. To understand when the moment has come, you need to periodically check the temperature of the surface with your hand. When a chemical reaction occurs, it will become hot, therefore, it is time to take a knife or blade. As you can see, puttying auto is not a difficult thing, but it involves a lot of nuances. Well, now let's go to the final part of this article and determine how much material we need.

How much to buy fillers?

This question can not be answered unambiguously. This is due to several factors: for example, the number of deep dents, the total area to be worked on, and so on. One can only say that the universal shredder is considered the least economical. It is bred in a proportion of 1:20, and it should be applied within 20 minutes, after which the mixture is no longer suitable. If the number of deep dents is small, then more finishes are required. Again, a lot depends on how much surface we need to process. In all circumstances, it is desirable that the thickness of the layer is not less than two and not more than four millimeters. As you can see, the consumption of putty depends on many factors, and therefore it is impossible to name the exact figure. Well, almost everything on this topic. Although it is worth saying a few more words about how to putty the car.

Conclusion

So all the same - how to properly putty the car? First of all, pay attention to the fact that after applying the next layer it is necessary to withstand a certain amount of time and allow the material to dry. After that, polish. And only then apply another layer. So you get the most flat surface. And it's best to do everything right the first time, because this is a very costly occupation. Therefore, pay special attention to quality and do not be afraid to spend a little more of your time. Finishing putty is used by the last layer to get a smooth surface, do not forget to degrease it and only then proceed to the primer. I would like to say that if you do everything right, and then paint the car, you will be surprised at how beautiful it looks. Well, perhaps, and all that can be said about how to properly putty the car. As you can see, here all the stages are important, and without fulfilling any of the conditions you will not achieve the expected result, and all work will be reduced to nothing.
