How to seal a plastic water tank. How to seal a plastic container How to seal a plastic spray bottle

A plastic tank is a convenient water reservoir that ensures the preservation of liquid parameters for a long time. It is not destroyed by moisture and is not prone to rust, but can be deformed under the influence of external factors. How to seal it plastic tank for water? The choice of method depends on the nature of the damage and the type of polymer.

Causes of deformation and nuances of repair

One of the reasons for damage to plastic water containers is improper installation. An uneven platform and the presence of sharp objects can lead to changes in the geometry of the tanks, the appearance of cracks and leaks. Deformation can also be caused by mechanical influences, including impacts during operation.

Before sealing a plastic water tank, you need to know the composition of the material that was used to make it. Depending on the feedstock, the following types of polymers are distinguished:

• Polyethylene (PE-HD). It is characterized by a combination of hardness and ductility, which simplifies the processing of plastic. Polyethylene low pressure resistant to various organic and inorganic environments and retains its parameters at temperatures from -50..+80 °C.
• Polypropylene (PP-H). It is characterized by increased hardness, tensile strength and chemical resistance.
• Polyvinyl chloride (PVC-U). Withstands temperatures ranging from 0...+60 °C, as well as exposure to oxidizing environments and chemically aggressive substances. In addition, it has high strength and hardness.

The type of polymer influences the choice of method by which damage and leakage of containers is repaired. Repair of plastic water tanks made of plastic with different compositions is carried out using certain technologies.

Damage repair options

Restoring the integrity of polyethylene containers is complicated by the low adhesion coefficient of the material, due to which the surface rejects the epoxy resin, the composition for cold welding, adhesives and sealants.

• From small crack You can get rid of it by sealing it with waterproofing bitumen tape.
• Another option is to repair the damage using a patch made from a piece of plastic and special modeling glue. The main thing is to thoroughly clean and degrease the surface.

How to seal a plastic polypropylene water tank

You can use fiberglass patches that are secured with molten polymer. To do this, the surface of the container at the site of damage is cleaned and heated with a hair dryer.
Then liquid plastic is poured from the gun and a piece of fiberglass of the required size is applied.
To ensure a strong fixation, the repaired area of ​​the tank is again heated with a hairdryer.
When choosing a method for restoring polymer containers, you should take into account the water pressure during their operation. It has a significant impact on the deformed area and can increase the size of the damage.

Restoring tanks using welding

One of effective ways Welding is used to eliminate deformations of plastic tanks. Its action is based on the ability of materials to transition from a solid to a viscous state under the influence of high temperatures.

To repair plastic tanks, there must be no water in them.

The container is emptied of liquid, and the damaged area is cleaned and degreased. Then perform the following operations:

• heat the plastic in the deformed area, melting it to a certain depth; fill the crack with a heated rope or piece of polymer;
• cool and clean the resulting seam from excess plastic.

The result obtained depends on compliance temperature regime and skills to work with special equipment.

Tools and accessories

In everyday life, repairs of plastic water tanks made of various types of plastic are carried out using a soldering iron and a hair dryer. When purchasing these tools, you need to consider the following criteria:

• Power. For a soldering iron it should be at least 100 W, and for a hair dryer - 1600 W.
• Maximum temperature heating

When choosing what to seal a plastic water tank with, you should also pay attention to comfort when using the devices.
It is advisable to give preference to soldering irons with wooden handle, because due to high temperature polymer can quickly melt.
The hair dryer should have several attachments and a smooth temperature control system, which will allow you to set the desired mode when working with different types plastic.
When welding, you will also need a polymer rod designed to reinforce the crack. Its quantity and diameter are selected depending on the size of the deformed area.
More significant damage is eliminated by fusing patches from a piece of plastic with a suitable composition.
Buckets, basins, barrels and other household equipment are made of plastic. This material is practical, easy to use, but short-lived.

Any fall or mechanical impact may lead to cracks. And the container that allows water to pass through becomes useless. But seal a plastic water container It is quite possible that it will serve properly for some time.

It is quite possible to seal a plastic barrel at home. Let's consider two options for how to eliminate holes in plastic barrels and other containers.

Option 1

To work you will need following materials and tools:

• stainless steel mesh (you can take aluminum or copper),
• scissors,
• soldering iron 100 watt.

Operating procedure:

1. Cut off a piece of mesh with scissors.
2. We fix the mesh at the site of damage to the depth of the mesh thickness.
3. Align it along the seam, moving along the entire plane. At the same time, we solder the mesh in parallel with a soldering iron, hold the free edge with a knife, and immediately after soldering we cool it with a heat exchanger (knife) - this important rule so that the mesh does not bristle.
4. Using this method, we insert the entire mesh into the seam.
5. At the end of the work, the seam is completely sealed and reinforced, which gives it strength.
6. We repeat the procedure with reverse side containers.

VIDEO INSTRUCTIONS

Option 2

If you need to repair a container in which the water is under pressure, you can resort to another method.

To work you will need:

• patch made of flexible plastic,
• construction hair dryer,
• protective gloves.

Operating procedure:

1. Wipe the damaged area and remove dirt.
2. We start heating with a hairdryer at low power so as not to burn a hole or a defective area.
3. We heat the patch with a hairdryer on the side that will be adjacent to the crack. We are already heating at a higher power.
4. Apply the patch to the damaged area and continue heating it with a hairdryer, adding more power. You must wear protective gloves on your hands to avoid getting burned. It is important not to overheat the surface.
5. Smooth the patch with your fingers and wait for it to cool. We pour water and check the quality of work.

Final sealing and smoothing out irregularities on the repaired plastic tank
The first method has proven to be the most effective in practice. The second one is more suitable as a temporary measure.

How to seal a plastic tank or water barrel - choosing an epoxy discount

If the defect in the plastic container is small, you can use epoxy glue. Two-component epoxy adhesive will help effectively solve the problem of a leaky plastic tank.

It is characterized by increased resistance to moisture and chemicals, polymerizes in just 1 hour, non-flammable.

It is necessary to cut off the required amount of glue, knead it with clean hands until a homogeneous mass is obtained, fashion a cone out of it and insert it into the hole in the tank. Fix securely for a few minutes.

Then you need to wait 2 hours, after which the container can be used.

Features of epoxy adhesive “Contact”:

• restores the shape of products and also hermetically fills voids,
• is not afraid not only of water, but also of oils, solvents,
• the repaired tank can be used at temperatures from -40C to +150C,
• within 3-5 minutes the glue can be corrected, and after an hour it can be cleaned, ground and subjected to other mechanical stress,
• The glue is sold ready for use.

Price of this composition from 150 rubles per package of 50 g.

They also have similar properties adhesives "General Purpos Permapoxy PERMATEX"(from 314 rubles for 25 ml) and “Plastic Weld Permapoxy PERMATEX” (from 320 rubles for 25 ml).

You can purchase epoxy adhesives in most construction stores, as well as via the Internet.

How to seal a plastic tank? Usually the issue is resolved with the help of a kit for repairing plastic containers, but remember if you want to use this method for a long time, such repairs will not help you. All capacitive products in 95% of cases are made of two materials: polypropylene (PP) and polyethylene (PE), which in turn have very low adhesion, that is, very resistant to chemical influences. Almost no glue sticks to them, and no patch with glue will provide high-quality repairs, professional repair by welding is required!

How to seal a plastic gas tank?

How to seal a plastic gas tank is a serious question; not every car service center has specialists who can restore a plastic fuel tank and, moreover, give a guarantee for sealing! You can repair it yourself, but for this again you need equipment and a simple hair dryer is unlikely to save you, where will they give you a guarantee for their repair? Our workshop both repairs and provides a guarantee for the repair of the fuel tank; specialists travel to the repair site if necessary by agreement.

Many people are concerned about one important question: how to seal a gas tank? Various car breakdowns can catch the driver at any time and most likely you won’t even expect it. One of the most serious problems is a breakdown of the gas tank. It needs to be solved very urgently, and at least partially.

In fact, fixing a gas tank is not that difficult for a person who has at least a little understanding of mechanics and has held a blowtorch in his hands. If you are unfamiliar with how your car works, you will have to learn, because the problem is really very serious. Many people ask the question: “How to seal a gas tank yourself?” First you need to know where it is. It is often located in the right corner of the rear sector of the car.

Due to this placement, the gas tank can ensure the safety of the driver and passengers. Find it and examine it carefully.

Your task is to understand the cause of the breakdown and where is the hole that needs to be soldered. After all, it is the lower part of the car that most often suffers from physical impact. But here, driving style can also be a factor in the breakdown; if you drive carefully, then most likely this problem will bypass you. The only thing you can expect from it is corrosion and rust. Time will take its toll, especially on domestic cars.

Fast work

How to seal the gas tank if an accident happened on the highway? First, drain all the fuel that is inside. You will need a jack to tilt the car and then use a tube to drain the fuel. But even after this, do not start work, you need to wait until the gas tank is completely dry, otherwise it may catch fire.

Next, assess the damage to the gas tank and identify the location of the breakdown. Your task is to carefully remove it for repairs. When the part is removed from the car body, it is necessary to determine whether there are additional holes in the gas tank. The process is quite delicate, so it is better not to rush here. It is necessary to carefully remove the gas tank from the car and carefully inspect it. Only after this can you start working.

Exceptions

There are several types of critical gas tank failures, but they are often solved in a simple way. If the breakdown occurred while driving and you are on the highway, then it is better to start by installing patches on the gas tank. This can be done using only a wrench.

Using available tools, it is necessary to widen the hole in the hole so that a bolt can be inserted into it. Then put a washer with an elastic band or a tight gasket on it, and then insert this structure into the neck.

Also, from the outside of the gas tank you need to install a special cuff with a washer, which can simply be tightened using a regular nut. This design will help you get to the car service center, where specialists will already carry out the main work.

Simple solution

In some situations, you can eliminate a hole in the gas tank using good glue or any analogue. For not very serious damage, this method will be the most relevant. All you need is a good piece of cloth, which you need to soak in glue and apply to the damaged area.

When you see that the fabric is firmly stuck to the damaged area, treat it with nitro paint; this temporary repair will allow you to easily reach to the nearest car service.

After these tips, you will most likely no longer ask: “How to seal a gas tank?” Now you can carry out repairs yourself at any time and protect yourself from even greater damage to the gas tank.

Repair of any type of gas tank without a trip to the service station

Car breakdown is a fairly common occurrence that can catch the driver in the most unexpected situation. Failure of a gas tank is a serious problem that must be at least partially eliminated at the scene of the accident. This will allow you to transport the car to the nearest service center, where it will be possible to carry out a major inspection and repair. Repairing a gas tank with your own hands is not too difficult for people who have some knowledge about such repairs.

Location of the gas tank - lower right corner of the rear sector vehicle. This is due to ensuring safety for the driver and passengers, as well as the formation of the correct center of gravity in the car, which improves its handling. However, the lower section most often suffers from constant physical impact, which leads to repeated damage to all the mechanisms located here. The fuel tank is no exception.

Causes of damage to the gas tank and basic repairs

Failure of gas tanks is most often associated with the gradual development of corrosion processes. Their impact is especially dangerous on inner part fuel tank. The provoking factor for the appearance of rust is water. It is almost impossible to avoid it getting into the tank.

Also, the cause of holes in the gas tank may be a malfunction in the vehicle's power system. A discharged pressure is formed inside the tank, which provokes the formation of an extreme load on all the walls of the fuel container. After some time, it becomes covered with small mechanical cracks.

Rules for repairing a gas tank of any type:

1. Before starting the procedure, all available fuel must be drained from the gas tank. Using a jack, the car is installed in an inclined position. Gasoline is drained using pipes. Next, the gas tank should be thoroughly dried.
2. Determine the extent to which it is necessary to completely remove the fuel tank to carry out repair work. It is recommended to take into account the area of ​​damage and the degree of ease of repair.
3. Determine the feasibility of conducting full monitoring of the tank for the presence of additional holes.

Methods for repairing fuel storage tanks

There are several ways to troubleshoot. Most of them are applicable in extreme conditions, which will avoid spending additional money on calling a tow truck.

Installing the patch using a nut bolt and a rubber gasket. First, using available means, you need to expand the hole in the tank to a size that matches the bolt. A washer with a rubber gasket is placed on its narrow part. Then the entire structure is inserted into the hole through the neck. A cuff with a washer is installed on the outside and tightened with a nut.

The rubber must be petrol resistant. Not every driver has such material stored in his car.

How to repair a gas tank yourself: detailed instructions with video

A camera from any truck will be suitable as a replacement. This patch is considered quite durable. At correct installation You can wait a bit before going to the service station. This method is often used by truckers who spend most of their time on the road. A good patch can last more than five years.

Use Moment glue or any of its analogues to repair damage. The method is relevant for not very serious damage. To create a patch, you need a piece of dense but pliable fabric soaked in glue. It needs to be pressed firmly to the site of injury and held for a while. After the main gluing, the patch should be treated with nitro paint from the repair kit. This is a temporary measure to allow you to get to the nearest service station.

On - repairing a hole in the gas tank:

Temporary replacement of the gas tank with any bottle. The method is suitable for breakdown of the fuel capacity of carburetor-type cars. A plastic or any other container is filled with gasoline, and a hose running from the gas pump to the fuel tank is immersed in it. The container should be securely fastened so that it does not tip over and cause damage. negative consequences. This method will easily help the driver get out of a difficult situation.

Repairing damage using laundry soap. The method is considered effective only for superficial problems.

Sealing the crack area with epoxy glue and fiberglass. The gluing area must be thoroughly cleaned and dried, and the gasoline must be drained. Clear the work area sandpaper, degrease and dry again. A piece of fiberglass must be glued to the damaged area. After complete drying, apply another patch of the same type. The number of layers must be at least three. When gluing the last layer, you should use a plasticizer, which can be aluminum powder.

Repair of plastic gas tanks and metal gas tanks using cold welding. Most universal method combating holes. Damage is removed using epoxy resin. The first stage of work is sanding the surface with sandpaper. Then mix in a separate bowl epoxy resin with hardener until a homogeneous mass is obtained. If heating is required, the container can be placed on the engine. This method also uses a fabric patch. Saturate it generously with the resulting mixture and apply it to the hole in the fuel tank. Let dry thoroughly. This patch is very strong and can last quite a long time.

Soldering as a type of repair of any type of gas tank

This method of eliminating a hole is the most sustainable. Suitable for both metal and plastic fuel containers. Knowing how to seal a gas tank, you can extend its service for a long time without buying a new unit at a car store.

Repairing a plastic gas tank is carried out using a soldering iron with a power of 250 watts.

The procedure itself resembles soldering plastic bumper. Soldering is done from the outside. It is necessary to monitor the tightness and strength of the structure. If additional donor plastic is used, its type must match the original one. Plastic composition markings are usually present on each part. This can be polypropylene (PP), acrylonitrile butadiene styrene (ABS) or polyamide (PA). Metal or copper mesh with fine pitch is used as a reinforcing material. The required piece of it is applied to the cleaned surface and, using a heated soldering iron, is fused deep into the plastic. The remaining plastic on the surface of the mesh is carefully smeared, creating a surface layer. The entire operation must be carried out at one time, otherwise it will not be possible to avoid the influx of multiple layers of plastic.

To repair a metal gas tank, only a soldering iron with a power of 500 watts is suitable. The most ordinary iron can help warm up the body of the gas tank. If necessary, a thin copper sheet can be used for the patch. The solder must be low-melting. The patch is soldered along the entire perimeter, which promotes tightness and reliability of fastening. Before soldering, the work area is treated with soldering acid. This is necessary for the reliability of the connection between the solder and the metal. The applied patch is covered on top bitumen mastic, which is particularly resistant to corrosion.

How to get your gas cap back on track

You can pay attention to a malfunction of the gas tank cap if, when opening it, you notice a noise effect associated with air being sucked into the container.

Repairing the gas tank cap is often associated with malfunctions of the plastic lead. You can replace it with ties that hold the wires together. To work you will need three clamps. You should insert one of them into the eye of the fuel tank cap and tighten the loop tightly. Already connect the second clamp to it. Make a small hole in the gas tank flap hinge and attach a loop knot to it. The second end of the clamp, located on the gas tank cap, will be tied to it.

Knowledge of the specifics of repairing a fuel tank is extremely useful for the driver. By understanding repair issues, not a single motorist will be taken by surprise, even far from civilization.

How to seal an aluminum tank

What are the effective methods and how to seal the gas tank so that it can be used in the future? Similar questions will be discussed in this section. After all, this topic concerns used cars more, and even then domestic production. Structurally, gas tanks are practically not protected from external damage, unlike their foreign counterparts. Often, small fractions of gravel, crushed stone, and asphalt bouncing off the rear wheels gradually destroy the coating of paint and primer, causing irreparable damage to the metal. After some time, the metal begins to rust. The driver begins to notice a fuel leak. How to seal the gas tank? Today there are two options for gluing:

Each method is good in its own way. Of course, you can find other ways to eliminate leaks in a gas tank, but they are less effective than the above. Tools and related equipment

• Half a liter of acetone;
• Epoxy resin;
• Fiberglass.

First, we purchase all the above materials, carefully read the terms of the instructions for use. Troubleshooting algorithm

• Degrease the surface of the gas tank with acetone.

  This procedure it is necessary to carry out several times, since the quality of gluing of the gas tank material depends on how well the degreasing is carried out;

Preparation stage and epoxy gluing For gluing, it is necessary to use glue of a viscous consistency, otherwise the effect may not be achieved.

• We cut the pieces of fiberglass so that they protrude 1-2 cm more than the perimeter of the crack or other damage. We thoroughly soak the scraps of fabric in epoxy;

Each subsequent layer should be slightly wider than the previous one and at intervals of 15-20 minutes. In addition last layer additionally impregnate with aluminum powder, which can be purchased at a car store. After a day, the structure will completely dry and harden. You can process it using fine sanding paper. We proceed to painting or priming, depending on the need. We use cold welding similarly to the above processes. Despite advanced technologies in the form of welding, many drivers prefer old, proven and durable methods. So the question of how to seal the gas tank has already been sorted out. A similar procedure can be carried out both in a garage and at a car service center, depending on your decision.

The reasons for damage to fuel tanks can be different, in one case it is rust, in another it is a normal trip on Russian roads. A small blow and almost immediately we begin to smell gasoline in the cabin. The fuel level arrow also tells us that gasoline is leaking. How difficult is it to repair a fuel tank yourself? If the gas tank is leaking, it is not safe to drive with such a breakdown, so do not put off repairing it for a long time. Before starting work, it is recommended that you familiarize yourself with:

General rules for repairing a gas tank

1. To drain gasoline from the fuel tank, you will need to tilt the car to one side with a jack and use a tube. If there is a hole in the gas tank in the lower part, then it will be faster to drain gasoline through it. Then you should dry the gas tank from gasoline vapors.
2. Repairing the gas tank without removing it or whether it is better to dismantle it is decided depending on accessibility to the place of damage and the type of repair work.

Folk way to repair a gas tank

Do you know how our grandfathers used to repair a fuel tank in the field? If a small crack appeared in the fuel tank, the hole was shaped into a round shape using a screwdriver. Next, we selected a bolt of suitable size for this hole and tightened it; first we put rubber washers on it (from the wheel chamber).

If you look at the old 130 ZILs, you will notice that their tanks are completely riddled with bolts, which suggests that this method is quite reliable and durable. Currently, this method finds its use among truck drivers, but the most popular for everyone affordable way Let's look at repairing the gas tank further:

Cold welding gas tank repair

This method is at the moment remains the most popular among car enthusiasts. It is based on a material called “cold welding”, which can be found in any household store. The point of this product is that when the two components are mixed, the resulting plasticine-like mixture hardens in 10-30 minutes, which is ideal for patches. If the damaged surface is first cleaned of dirt and dried, then the repair by cold welding will be quite durable, and it is unlikely Will you ever return to this damage again? However, if you try to repair a hole in your gas tank without prior preparation, the treatment will be temporary.

Repairing a gas tank using soldering

For this method, you will need soldering flux (fat, rosin) and a hammer soldering iron (200 Watt). We clean and degrease the space around the damage site, and thoroughly rinse the tank itself with water.

We treat it with 20% phosphoric acid and solder two galvanized patches (flux-hydrochloric acid with zinc, pos-40 solder). Clean and tin the mounting surfaces of the patch and tank.

DIY gas tank repair

This repair of a broken gas tank can be called reliable, but the disadvantage is the mandatory dismantling of the tank.

Fiberglass and epoxy resin gas tank repair

Another way to fix a gas tank leak. In this case, the patch will be fiberglass and epoxy resin. We clean the surface in the same way, and then apply a layer of fiberglass, which is impregnated with resin. After drying, apply the second layer in the same way. The final stage There will be anticorrosive treatment. The gas tank was repaired in 4 hours! In the field, instead of epoxy and fiberglass, use Moment glue and any material (rag, rags). The layers are alternately impregnated and applied to the damaged area. This temporary solution allows you to reach the nearest service station without any problems.

How to glue a plastic tank

snim (Moscow) 9 Feb 2004 08:32:33	The reservoir burst, made of a material very similar to the one from which car washer reservoirs are made (white brittle plastic). How to repair a fuel tank. DIY gas tank repair Crack 10-12mm. No glue can remove this infectious plastic... Who glued it, tell me with what???
Anton (Moscow, Russia) 9 Feb 2004 12:02:33	It's most likely polyethylene or something similar. The only solvent is a soldering iron.
Destroyer (Moscow) 9 Feb 2004 13:44:46	Right: You need a heat gun and a hairdryer. We widen the crack to 2mm, the edges are chamfered. We apply a smooth metal plate on the outside, heat the tank around the crack with a hairdryer so that it is not yet leaking, but already hot, and fill it with a heat gun from the inside. Cool, cut off the excess. We insert the plate from the inside, heat it with a hairdryer from the outside, and fill it with a heat gun from the outside. Heat gun rods different colors, with different properties, explain to the seller where this tank is used, and he will select it. It’s simpler: without a hairdryer and fill it from one side. In general, it’s elementary: buy a new tank.
Alex21 (Volzhsky, Volgograd region) 9 Feb 2004 15:48:32	This plastic tank is utter rubbish... Plastic ages over time (your crack is most likely the first swallow), and as a result, it can suddenly burst along its entire height, spilling the contents onto the floor. This is exactly what happened to a friend - she was well at home, and heard the whistle of water from the valve.
snim (Moscow) 9 Feb 2004 19:56:00	2Destroyer: It won’t work from the inside 🙁 The neck of the tank is 5 cm in diameter. > Even easier, without a heat gun: Roll it up plastic bag(which is thin, without a pattern) into a thin tight tube, light it, drops begin to fall from it. Wow, I'll try this now. But it will stink... > It’s actually quite simple: buy a new tank No, it’s not simpler, it’s specific, from a sprayer. I poured water on the wallpaper and primed the walls... Hello, Alexander!!! :-) > This plastic tank is utter rubbish... Probably yes. > Plastic ages over time... No, it’s new, it’s not even a month old, but it’s burst, it’s an infection. I think I hit him with something.
Serg (Samara, Russia) 10 Feb 2004 02:33:43	2snim: Buy a hot melt glue stick and use a soldering iron or just a hot nail (like a spatula) to cover the crack with it. Only, initially, you need to degrease the surfaces of the crack - you can use acetone. Best regards, Sergey
snim (Moscow) 11 Feb 2004 11:26:37	Thanks everyone for the advice. The gluing was done using a hot-melt gun. Only here's a nuance: there were 2 rods - one transparent, the other matte. The first one didn’t glue, the second one patched up tightly! Best regards, Nikolay.
Voka (Tomsk) 12 Feb. 2004 07:46:45	It’s late, of course, but... It is advisable to drill the ends of such cracks. So that it doesn't spread further.

How to seal the gas tank? 2 time-tested methods

What are the effective methods and how to seal the gas tank so that it can be used in the future? Similar questions will be discussed in this section. After all, this topic concerns more used cars, and even those of domestic production.

Structurally, gas tanks are practically not protected from external damage, unlike their foreign counterparts. Often, small fractions of gravel, crushed stone, and asphalt bouncing off the rear wheels gradually destroy the coating of paint and primer, causing irreparable damage to the metal. After some time, the metal begins to rust. The driver begins to notice a fuel leak.

How to seal the gas tank? Today There are two options for gluing:

• Using cold welding to seal cracks and holes;
• Epoxy glue or popularly called fiberglass. It is better to buy a two-component one.

Each method is good in its own way. Of course, you can find other ways to eliminate leaks in a gas tank, but they are less effective than the above.

Tools and related equipment

• Several sheets of sanding paper;
• Half a liter of acetone;
• Epoxy resin;
• Fiberglass.

First, we purchase all the above materials, carefully read the terms of the instructions for use.

Troubleshooting algorithm

• We drive the car to inspection hole or overpass;
• We mark the location of the leak with chalk;
• We remove the fuel tank from the car;
• Pour out the remaining gasoline or diesel fuel;
• Be sure to dry it in the open air, since the vapors of the chemical reagent are explosive;
• Using a rag and a soap solution, we externally clean the gas tank from residual tar, dirt, and other impurities;
• For cleaning difficult to remove chemical compounds use coarse sandpaper;
• Degrease the surface of the gas tank with acetone. This procedure must be carried out several times, since the quality of gluing of the gas tank material depends on how well the degreasing is carried out;

Preparation stage and epoxy bonding

For gluing, it is necessary to use glue with a viscous consistency, otherwise the effect may not be achieved.

• We cut the pieces of fiberglass so that they protruded by 1-2 cm. greater than the perimeter of the crack or other damage. We thoroughly soak the scraps of fabric in epoxy;
• Carefully place the fiberglass cloth on the surface of the gas tank so that there is no air bubbles, otherwise, eliminate the shortcomings;
• Using a rag, remove excess glue and resin;
• Smoothes the glass strip using a small piece of plastic to make the platform even;
• After this, we proceed to apply the second ball and carry out a similar procedure. Depending on the degree of damage to the gas tank, the number of fiberglass balls is determined. Accordingly, minimal damage will be required minimum quantity fiberglass balls, I will require deeper affected areas more balls.

Note to the driver, it is necessary to remember that the quality of the rest of the structure depends on how the first layer is laid.

Each subsequent layer should be slightly wider than the previous one and at intervals of 15-20 minutes.

In addition, we impregnate the last layer with additional aluminum powder, which can be purchased at a car store.

After a day, the structure will completely dry and harden. You can sand it using fine sanding paper.

We proceed to painting or priming, depending on the need.

We use cold welding similarly to the above processes. Despite advanced technologies in the form of welding, many drivers prefer old, proven and durable methods. So the question of how to seal the gas tank has already been sorted out. A similar procedure can be carried out both in a garage and at a car service center, depending on your decision.
