If due to an accident or for other reasons, you will need to putty the car, and you do not want to contact the professionals, you need to know a number of nuances.To some it may seem that this is too difficult, and some - on the contrary, that there is work for half an hour.In fact, to tell how to properly putty machine can be a very long time.But let's talk about the most important.
Step One: Preparing Your Car
You probably already know that before you update any surface, it is necessary to prepare.This is exactly the case.This is done in order to get coverage as much as possible qualitative and reliable.The first thing to do is to carefully sand the surface and remove any dust.In addition, the need to degrease both metal and plastic parts.Well, the final stage in this section - the processing of the prepared surface corrosion-resistant primer.Simply put, this protection against rust.Let's talk about each of the items in detail, and then you will understand how to properly putty machine.It is worth to note that a greater role played by the quality of work, so each procedure must be done conscientiously.
little about sanding, dust removal and degreasing
So, we do not need to invent the wheel, so we will use the experience of the previous car owners or plants that are recommended for use with metal utensils use abrasive paper marks P80.To remove dust, it is best to use the blower pistols.Airflow per minute should be 140-160 l.Thus you can save yourself, because most of the consumption of the blower hoses are about 900-1000 liters.This loss of 70% of the electricity in the air.Also, do not be amiss to say a few words about the degreasing.Here we must pay special attention to and to choose those means, the composition of which contains the least amount of aggressive substances.This is due to the fact that they violate the state of polished sections.Now let's proceed directly to the question regarding the putties.As noted above, there is a lot of nuances.
Caulking car: general information
should understand that there is a huge selection of this material.In addition, the putty can be of different types, eg, finishing, roughing, universal.If we talk about the first layer, then it must be done roughing or universal putty.For this we need a special rubber spatula.In advance you must acquire and hardener why - let's say a little later.Please note that during application to the surface can be shrunk, it has the appearance of small dents and hillocks.In the first case, tint, in the second - cutting with a knife.But that's not all, as there is a further zashkurka.Here it is desirable to use fine sandpaper, as she rubs a very small layer of putty, and cleans the order of magnitude smoother coarse analog.Of course, if there is too rough patches, the use of medium paper first and then fine-grained.
How putty car
Now I would like to say a few words about the shrinkage during the work.The fact that it is because of this property, most beginners and throw the case for half of the way.To this index was optimal amount of solvent in the composition should not exceed 30%.At least, that recommended by most professionals in the field.If we talk about quality putties, the shrinkage is not more than 2%.When applying a thin layer of material visually it is virtually impossible to determine.For less shrinkage is best to mow smoothly old coating.If this is done rapidly, instead of 2 microns shrinkage we get 20, which is not good.If you use poor-quality solvents and resins, there is a great probability of secondary shrinkage.
How to put weight on the surface
And now just move on to the practical part and learn how to properly putty machine.Before you start, you need to mix the material with a solvent.This should be done until such time until a homogeneous mass.We need a set of different spatulas kit can be purchased at specialty stores.The surface is as even as possible, it is necessary to do the job quickly, but carefully, applying layer after layer.If we are dealing with a large dent, it is necessary to align it in 2-3 layers.Do not try to do everything at once.It is recommended to use universal putty.While it will solidify, and this for 15-20 minutes, you can deal with the other portion of the damaged surface.After the mass hardens, you can proceed directly to equalization, ie grinding.
continue to work
It is worth paying attention to the fact that after you almost leveled deep dent, it is best to use a finishing putty.It is necessary to wait until it dries, then use sandpaper P240.Since putty car must be carefully, and grinding is carried out as much as possible qualitatively.Process need not only the dent, but the next sections which will achieve the optimal result.In order to hide the damage place, we need to form a smooth transition, and for this it is best to use a fine abrasive.After all this, there is a degreasing and, of course, priming.But that's not all, because there are other issues that need to be addressed - such as bleed-through lanes on the spatula on the surface.Let's see how to avoid this.
Remove the contours of the spatula
First, it is the most important thing: do not try to remove the protruding strips before the material is frozen.Not only that, because you do not fix the situation, but also done extra recesses.But when the material hardens completely, cut the strip is quite difficult.It will take quite a lot of time and effort.However, there is the length of time when it is easiest to do.After about 5 minutes of applying the material becomes like rubber, this time with a sharp blade or something like that, you can safely cut all bars.To understand when the moment came, you need to periodically check the temperature of the surface of the hand.In the event of a chemical reaction it will be hot, therefore, time to take a knife or blade.As you can see, plaster cars - business, though not difficult, but it is understood a lot of nuances.Now let's move on to the final part of the article and to determine how much material we need.
How to buy fillers?
to this question can not be answered unequivocally.This is due to several factors: for example, the number of deep dents, the total area to be treated, and so on. N. One can only say that is considered to be the least economical universal putty.It is diluted in the ratio 1:20, and must apply for 20 minutes, after which the mixture was no longer suitable.If the number of deep dents is small, it will take more finishing putty.Again, much depends on how much we need to treat the surface.Under any circumstances it is desirable that the thickness was not less than two and not more than four millimeters.As you can see, the consumption of filler depends on many factors, and therefore can not give an exact figure.Well, almost everything, and on this subject.Although it is worth saying a few words about how the auto putty.
Conclusion
So still - how to putty machine?The first note of the fact that after the application of the next layer is necessary to keep a certain amount of time and allow the material to dry.After that make grinding.Only then apply another layer.So you will get the most even surface.And it is better to do it right the first time, because this is a very costly exercise.Therefore, pay special attention to the quality and do not be afraid to spend a little more of your time.Finishing putty used for the last layer of smooth surface, do not forget to degrease it and then proceed to the primer.I would like to say that if you do everything right, and then paint the car, you'll be surprised at how well she looks.Well, perhaps, and everything that can be said about how to properly putty car.As you can see here all the steps are important, and without performing any of the conditions you will not achieve the expected result, and all work will be reduced to nothing.
