Metal putty is used in cases where scratches, small holes and dents appear on the coating. With its help, the surface returns to its original state. The variety of putty is great, but not everyone can be suitable for metal.
There are putties for metal, which are divided into one- and two-component. Manufacturers produce mixtures of different compositions:
Each composition has its own specific characteristics and features when applied to a surface. If there is a choice when buying a putty for metal products, you need to pay attention to its properties, a high-quality putty should have the following:
Which putty for metal is better, everyone decides for himself when buying.
Two-component putties - These are polyester-based compounds, to which a hardener must be added before use. The advantages of this type of putty are that it:
On the construction market, polyester putties are presented in the following options:
By manufacturers of building materials, putty mixtures for metal are produced in the form of powder (reinforced metal) and fiberglass. The first ones are resistant to vibrations, they need to be applied on a flat surface, the second ones are able to seal through holes, noticeable irregularities and big size dents, this kind of mixture is not resistant to shaking and mechanical stress.
The main advantage of polyester putty is that the unused part of it, to which no hardener is added, can be stored further, until the period indicated on the package, and will not become unusable. Store the curing agent and base separately.
Advice! If you need a high temperature filler for metal surfaces, choose from a range of polyester blends that are heat resistant.
In the video: how much hardener you need to add to the putty.
Epoxy putty for metal is also two-component. It has the following advantages:
Nitro putty is a single component formulation that is ready to use right away. The material is easy to putty on metal parts, but has a shrinkage of up to 15%. Apply the mixture to repair small scratches and dents. The coating layer is applied at a time no more than 1 mm, so the area is covered a couple of times. It is recommended to prime the surface before starting the filling.
In the nitro putty, the bulk of the mass is occupied by special fillers that are included in it. Fillers can be neutral powders or fibers that add bulk. The type of composition depends on the filler, it happens:
In texture, nitro putties are pasty (applied with a spatula) and liquid, which are applied with a brush.
Pentaphthalic compounds give a noticeable shrinkage of 3 to 5% and are suitable for removing minor damage. This type of filler for metal must be applied in a very thin layer to avoid cracking. In addition, pentaphthalic putty requires drying when temperature conditions up to + 80 ° C.

Before you start puttingtying a metal surface with your own hands, you need to decide on the type of mixture that is suitable in this case. However, among the variety of filler materials for metal, the most popular is a mixture with an epoxy composition.
After acquiring the necessary material, a step-by-step process takes place:
Metal plastering specialists recommend the following:
If you need to choose a high-quality putty mixture for working with metal parts, pay attention to its purpose and properties specified by the manufacturer.
Today, domestic putties are divided into the following types:

Many repair work related to painting and restoration of paintwork of car bodies requires preliminary preparation to obtain a high-quality result. For these purposes, specialized putties for metal are used, which allow not only to eliminate small chips and scratches on the surface of the car, but also to close up significant dents and even through holes obtained after an accident or mechanical stress.
Domestic putties for metal are divided into the following types:
Polyester (PE-00-85 putty), using unsaturated polyester resins as a base and a hardener as the second component. They differ in insignificant shrinkage (up to 0.5%) and have good adhesion. Reinforced with fiberglass, these metal fillers can be used to seal large holes, and the addition of metal powder to its composition allows for an ideal combination with the base material and high vibration resistance.
It is unacceptable to use polyester putties for metal on painted and plastic substrates. When drying, the temperature should not exceed 75 ° C to avoid cracking.
Epoxy (EP-0010, E-4022 putty), also using two-component compositions of epoxy resin and hardener. A fairly common EP-0010 putty has high chemical resistance, and with significant strength it has a minimum shrinkage (about 0.1%), and can also be used on all types of surfaces due to increased adhesion. Before using these metal putties, it is recommended to add a little chalk, kaolin or talcum powder to them to avoid swelling from vertical surfaces. EP-0010 putty hardens in 15-20 minutes, but it takes about a day to dry completely.
Pentaphthalic (PF-002 putty), characterized by noticeable shrinkage (3-5%) and suitable for repairing minor damage. Such fillers for metal must be applied with a layer of up to 0.5 mm in order to avoid cracking. Pentaphthalic putty PF-002 requires prolonged drying (up to 24 hours) at a temperature not exceeding 80 ° C.
Nitro putties (NTs-007, NTs-009) do not require hardeners, are convenient to use, but have significant shrinkage (up to 15%), which limits their use mainly to eliminate minor scratches and damages. Nitro putties require a preliminary priming prior to application in order to obtain a good adhesion to the substrate. It dries very quickly (1-2 hours) and easily withstands elevated drying temperatures (90-100 ° C).
EP-0010 putty two-pack epoxy resin material. EP-0010 is used for leveling primed or unprimed metal and non-metallic surfaces, and also as a primer for epoxy materials. EP-0010 putty is used in coating systems that are used both in atmospheric conditions and indoors.
Solvents R-5A, R-5 or R-4.
At a temperature of (20 ± 2) ° C, putty applied with a spatula - 1.5 hours, putty applied by spraying - 6 hours.
Preliminary priming of the metal surface with primers such as EP, VL. In the case of applying a filler on pure metal, surface preparation is carried out according to 9.402. EP-0010 putty is applied with a spatula, pneumatic spraying.
Before use, make sure that the base of the putty is well mixed and homogeneous throughout the container. To prepare the composition, mix the hardener with the base in the ratio specified in the quality document for each batch of material, and mix thoroughly for at least 10 minutes. Before applying the putty by pneumatic spraying, it is diluted to a working viscosity of 18-20 s using a VZ-246 (or VZ-4) viscometer with a nozzle diameter of 4 mm with R-5A, R-5 or R-4 solvents. EP-0010 putty is applied to the metal surface with a spatula, pneumatic spraying at an ambient temperature of at least 5 ° C and a relative humidity of not more than 80%. To exclude moisture condensation, the surface temperature should be at least 3 ° C above the dew point. After the layer has completely dried (24 hours at 20 ° C), the surface of the putty is sanded and dust-free, after which subsequent layers of putty or other paints and varnishes are applied. Use the solvents specified above to flush the instrument.
In unopened original packaging 12 months from the date of production.

PUTTY "ALU"; Good day! Can you tell me what kind of putty is right for me to fill the dent? I want to prime with acrylic from Vika. Where to put the filler, before or after the primer? Hello. The putty must be applied before the ground. The type of filler used will depend on the size of the dent and may need to be straightened. Take a look at our catalog and decide on the type of putty yourself. Is it possible to put putty on the car if it was on the street all the time? Hello. Drive into the box, prepare the surface for applying the putty. I don't see any problem in your question!
Good day! How to remove grinding products ??? After sanding the soil ?? Is it worth it to degrease again? If you are sanding on wet, you can remove the sanding products with an ordinary rubber raikel (spatula), if you sand on dry, you can blow it off with a blow gun. Degrease is worth it.
We have a forum ... Come in and discuss :) forum.sibcolor.ru Good afternoon! After opening the NOVOL UNISOFT putty, I saw that there were small grains, the shelf life had not yet expired, after application there were not large craters and lumps, I diluted with a hardener correctly, maybe the storage conditions were violated ??? Tell me please??? I do not know what to do, can I throw it out ??? or wipe it properly and then apply a primer, maybe it will hide it ?! Good afternoon. It's best to give up of this material and, if possible, return his point of sale.
We have a forum ... Come in and discuss :) forum.sibcolor.ru Hello. I have quite a lot of product: NOVOL "UNISOFT" PUTTY, but, unfortunately, it has expired for more than half a year, the storage conditions were almost perfect, what should I do? And is it possible to continue with expired products, in particular NOVOL putty. Thank you in advance! Hello. I cannot recommend you the use of expired material. Whether to use it or not is up to you.
We have a forum ... Come in and discuss :) forum.sibcolor.ru Hello. Can you please tell me if I can use fiberglass putty without hardener. Will it dry? Hello. In principle, you can use it, but you don't need it. The hardener reacts with the material making it stronger and more stable. If no hardener is used at all, the final result after painting may not be predictable (shrinkage, contouring, etc.).
We have a forum ... Come in and discuss :) forum.sibcolor.ru Can you please tell me if it is possible to dilute the Body-soft putty with something other than the hardener from the kit. The hardener is over, but there is still a lot of putty. We use it for filling forged products... Thank you in advance. Hello. I can only offer another can or two putties and use a hardener from them. Hardener for fillers is not sold separately.
We have a forum ... Come in and discuss :) forum.sibcolor.ru I have unisoft putty. Everything is in English, how to dilute it? how long does it harden? Hello.

Good afternoon. Putty metal surface(Polyester two-component glass-filled putty). It looks like I added little hardener. Two days have passed, it has not dried up. It is difficult to remove the putty, a thin layer remains, reminiscent of smeared plasticine. The surface is sticky. Tell me how you can remove the putty? Maybe some kind of solvent? Tell me the brand) Hello. Alternatively, too much layer was applied and hardener was added out of proportion. Remove the filler with a spatula to the metal and clean the rest with a coarse abrasive. If you want to shorten the time, you can use a wash old paint. Can polyester putty be used on wood? Hello. The putty presented in our assortment should not be used. Good afternoon. Mixing ratio and working time with body fine putty. Hello. On the packaging with the material, all these indicators should be in the form of pictograms. Approximate proportion of addition of hardener 2-3%, shelf life on a spatula 4-6 minutes after mixing with hardener.We have a forum ... Come in and discuss :) forum.sibcolor.ru Hello! Please tell me how you can find out the production time of WODY putties and primers? Hello.

We have a forum ... Come in and discuss :) forum.sibcolor.ru Hello. We need a heat-resistant putty for metal. After processing, parts are painted at a temperature of 260 degrees. Hello. There is no heat-resistant filler in our range.
P.S. If you have any more questions, I suggest discussing them on our forum forum.sibcolor.ru Good evening. Please tell me what to do if the putty place stood in a damp place for two days, and before that I washed off the dust from the skin with water, can it be primed? and can acrylic and acrylic paint be thinned with solvent 647? and whether the hardener from the ground is suitable for acrylic paint? Thank you in advance! Hello. In connection with the launch of the forum, your question has been moved there to the appropriate topic. You can see the answer to your question here >> To participate in the discussion on the forum, you need to register. I suggest continuing the discussion of your question on the forum.
P.S. The forum is under testing, thank you for your understanding. Tell me in what proportions to interfere with Body Soft putty. I did not find anything about this on the bank. Thanks. Hello. Add 2-3% hardener to BODY SOFT putty. Hello. Can you please tell me, the hardener from the novol liquid putty is lost !! How can you replace it ??? Hello. The hardener for Novol liquid putty cannot be replaced by anything and we do not have it on sale separately. Alternatively, you can buy another can of liquid putty and “stretch” one hardener for 2 cans, which will slightly increase the drying time. Good day! You write that (The putty always fits only on bare metal.) And in the description "UNISOFT soft putty" It can be used on the following types of surfaces: polyester laminates, steel, galvanized steel, aluminum, acrylic primers, 2-component old varnish coatings. so do I need to remove the paint to iron or can we just remove the varnish? where it is cracked from deformation, everything is clear, we clean it to iron, and where there are just scratches, do we also remove the varnish or to iron? Hello. If there is a deep scratch on the surface, then it can be repaired with 1K putty without cleaning it to bare metal. As for the manufacturer's recommendations, that is a difficult question. In the end, it's up to you to decide. As practice shows, that part of the putty, which is applied to the old, although quite strong paintwork material, tends to give "contouring" after priming and painting, which is noticeable in the end result. But this is not always the case. Therefore, we recommend to all our clients, just in case, to completely remove the old paintwork before filling. Can you please tell me what is like a liquid putty and is it desirable to apply it in order to betray the ideal surface of the part? Like the liquid putty, there is only Kansai primer, which can be used in a similar way. If you want to familiarize yourself with the entire range of putties available in our offer, then go to: Catalog => FILLERS => POLYESTER FILLERS => LIQUID FILLER. Liquid putty is usually used to fill irregularities, deep scratches on roughly finished metal and fiberglass parts. If you remove the surface well enough before priming, then the use of "liquid" is not necessary. I would not recommend to abuse it, tk. with a large layer of application, a slight "shrinkage" of the material is possible
Preparing a body part for repair is the most important starting point to achieve best quality at the exit. I hope no one will dispute this axiom?
So where should you start?
Take the front wing as an example.
To determine the nature of the damage and draw up the correct work plan, the suspected element should be properly washed. Moreover, after the water, wipe it with White Spirit and solvent. This action will give us a complete picture of the damage. It should be noted that behind a small defect in the wing (a scratch or a small dent), paint chips and other minor defects can also be observed. And, if it is destined to paint it, then it must be done with all dignity, regardless of different faces.
So, we found all the defects - what next? And, then we come to the conclusion that we will have to prime the entire element. Hence, the conclusion is that we remove all defects from the surface.
Let's imagine that we have a long scratch on the surface of the wing, forming a shallow dent, and several small scratches and chips.
What to do? - The age-old question of the Russian intelligentsia.
I explain point by point:
1. Matting the entire wing surface with abrasive P220-240. You can use an orbital sander, but where you can't crawl - then manually. On a matted surface, all dents and small defects appear, as it were, and they become better visible.
2. A scratch with a dent must be sanded so that there are no sharp edges of chipped paint (If there is rust, remove it to zero). Do not be afraid to overwrite the excess. We grind the scratch and its edges with an abrasive (sandpaper) P120. This is a fairly coarse abrasive grain, with which the best adhesion of the putty to the surface is achieved.
3. Next, we grind small scratches and chips. We expand them along the plane. So that there are no sharp corners and exfoliation from the surface.
4. Now, it's time to putty.
If you are not yet in the know, then great news for you - putty, it is not alone! She has many varieties. Let's start in order:
2. Filler with aluminum filler (coarse two-component filler-filler, for filling deep dents, as a primary layer). Excellent processing properties, low drying shrinkage.
3. "Universal" putty - (two-component), coarse enough to remove shallow dents and irregularities, usually yellowish in color.
4. Putty "Finishing" (two-component), usually white, excellently processed. It is applied over a coarse putty for a more precise leveling.
5. One-component putty (just finishing?) In a tube, to fill micro-scratches and microroughnesses. Recommended for final filling.
Having cleaned the repair surface with abrasive P120, we proceed to puttying. Do not forget to first degrease the repair surface. If traces of rust remain on the repair site, they should be treated with a "rust converter" according to the instructions on the bottle.
We knead the coarse putty with the hardener - stirring thoroughly so that there are no pink streaks (usually pink color- hardener) and evenly fill the repair area with a spatula with light pressure. Do not try this procedure at one time. We applied, waited 10-15 minutes until the putty gets up. Usually, 3-4 kneading and greasing is required to achieve complete filling of the defective spot.
The next step is grinding.
We sand with an abrasive grain P120. Carefully, trying not to climb outside the repair area. (Otherwise, extra scratches - do you need it?)
To achieve safety - glue the repair area with masking tape, preferably in two or three layers. For better control, before sanding, I strongly recommend wiping the surface to be treated (dried filler) with black developing powder. It will be easier to control defects (where putties should still be greased).
I recommend grinding with a special plane, the highest quality processing is achieved.
When sanding a part, pay attention to abrasions. If the metal has begun to protrude, then there is no point in rubbing further - you need to add putties (to fill the gap formed between the wiped areas).
Remember! The putty is much softer than paint (varnish), and even more so than metal, so it can be wiped off with a sandpaper faster and easier. Therefore, if metal begins to show through on the surface to be treated, stop sanding and add another layer of putty.
Having sanded out a coarse putty and having achieved the desired result (as they say, "almost done"), you should apply the finish on all suspicious places to be treated (as well as on all the places indicated by the developing powder) and process it with sandpaper on a plane with P220-240 abrasive. By doing this, you will cut (rub) the larger risk caused by preliminary grinding with an abrasive with a grain of P120, and also smoothly grind all the transitions.
Putty for metal is a material that must be used when working with metal surfaces.
There are several varieties of this composition. The choice of the most suitable one depends on the qualities of the work to be done. Some mixtures shrink significantly, others are fast drying and have increased strength.
When choosing this or that material, you should carefully familiarize yourself with its features in order to avoid the appearance of microcracks on the surface after the composition has completely dried.
Nitro putties dry instantly All putties designed for metal work are divided into one- and two-component. Modern manufacturers produce many different formulations:
Before purchasing one of the ones offered by manufacturers, you should know that there is no need to mix only nitro putty with the hardener. Its main feature is its short drying time. It dries almost immediately after it reacts with air. However, after a short time, the entire treated surface can be covered with the smallest microcracks.
When choosing a putty for metal, you should pay special attention to mixtures consisting of two components.
Mix epoxies thoroughly One of the most popular is epoxy putty for metal. It is a base and hardener that must be mixed thoroughly to get the job done.
Its main advantage is that after preparing the required amount of the composition, you do not have to worry that the unused amount of putty will simply become unusable. Hardener and base are stored separately.
Epoxy filler for metal is intended for:
Due to its resistance and a high degree of resistance to chemicals, epoxy putty is used during renovation works to restore the car body.
Not only bodywork is done with epoxy putty. It has found wide application in shipbuilding and in the repair of any metal parts and surfaces.
Do work with gloves Base or filler - most of composition. Dilution and mixing is carried out strictly in accordance with the attached instructions.
Compliance technological process guarantees the creation of a full-fledged high-quality layer with high adhesion.
The layer thickness should be kept to a minimum. It ranges from 1 to 2 mm. The hardening time is 20-30 minutes, but experienced craftsmen it is advised to continue manipulations no earlier than a day after puttying.
Rust must be removed before starting work. To do it, you need to have certain skills.
Among the many putties, epoxy is the most popular.
The metal surface must be thoroughly cleaned of all kinds of dirt, but you can apply epoxy putty without preliminary priming:
Apply the mixture with a thin spatula The composition is applied to the metal with a special thin spatula, filling all cracks, cracks and chips on the surface.
Excess putty is removed with the same spatula so that there are no depressions or elevations above the main surface at the place of application of the composition.
After complete hardening, they begin to process the putty area with sandpaper, moistened with water.
The result is a flat and smooth surface that can be primed and painted after drying.
Fine-grained mixture fills cracks well To carry out repair work, epoxy putties are used:
Each of them has certain positive qualities and is used for high quality bodywork. So, for example, fine-grained perfectly fills the smallest cracks, allows you to create the most even and smooth surface and can be used as topcoat before painting.
Large defects on the metal surface can be corrected with a reinforced epoxy containing. It is used to remove traces of significant dents, but most often craftsmen use such a putty to eliminate small through holes on the surface of metal parts of the car body.
Lightweight is necessary to correct defects on the surface of various parts. It practically does not change their weight and is characterized by a high degree of strength. Epoxy putties are available in the form of pastes or liquid formulations designed to be applied with a spray gun. For more information on how to apply putty on metal, see this video:
In contrast, putties with the addition of relatively large metal particles are very difficult to process with sandpaper, although their main positive quality is high level strength and reliability. With their help, the created surfaces acquire a lot of positive qualities, including a long service life.
Putty for metal is used when surfaces are damaged: when dents, small cracks or irregularities appear on them. This will make it possible to return the product to its original appearance.
There are many different fillers available, but not all can be applied to metal. The article will tell you what types of putty exist, how to putty the metal and the features of its use.
When choosing a high-quality putty for a metal surface, it is necessary that it has the following properties:
There are several types of fillers for metal application.
Of these, the most commonly used:
Each of them has its own properties and features of DIY application.
Two-component putties are compositions, in the main polyester mass of which a hardener must be added before using the mixture.
The main features of such a coating are:
Tip: Polyester materials should not be used on materials with paint coatings, anti-corrosion primers and plastic materials.
Two-component putties are:
Polyester putties are produced:
Tip: If you need a heat-resistant putty for metal, you need to get acquainted with polyester mixtures with such properties.
Epoxy putty for metal is also two-component.
Its advantages:
Nitro putty is a one-component, completely ready-to-use composition. It is quite simple for metal putty, but it gives a large shrinkage, up to 15%. This allows it to be used for repairing small scratches and irregularities.
At one time, a layer can be applied about 0.1 millimeter of putty, which requires covering the surface with the compound several times. It is advisable to apply a primary primer before metal putty. In such mixtures, the bulk of the mass is created by special fillers included in it.
It can be:
The filler in the composition of the material determines its appearance.
He might be:
Nitro putties can differ in consistency, they are:
Tip: When applying putties of any kind, the instructions must be fully followed, otherwise the compositions will not have all the properties they should have.
The mixtures differ in the drying method.
She may be:
Before purchasing a composition for putty, you need to familiarize yourself with its features, determine how it should meet the requirements in a particular case. Will help you choose the right mix of videos in this article.
