Silicone Aquarium

Aquarium leakage is a nuisance from which no one is immune. If it manifests itself, then you can go to the pet shop and buy a new house for fish. Independently eliminate the leakage is much cheaper, but only experts do not recommend the use of household glue "Moment", a tube of which is always in every home. So, we need some other glue that is suitable for such cases.

What requirements must meet the aquarium glue

In principle, two parts of ordinary glass can be glued together using ordinary superglue or using other adhesive synthetic products. However, if we are talking about repairing or manufacturing an aquarium, then not every glue compound will be suitable. And there are a number of reasons for this.

  • First, the walls of the existing aquarium experience a sufficiently large lateral pressure of the water mass. If, after drying, the glue at the junction of the walls becomes too hard, then there is the likelihood of fractures and cracks along the seam line.
Consequently, the aquarium adhesive composition must be elastic and work well in tension, without losing its sealant properties.
  • The second requirement is reliability.

The fact is that stretching acts on the glue-sealant constantly for a long time. In addition, the adhesive is affected by water from the inside and the air outside, ultraviolet radiation, as well as the temperature difference in the room (during the day) and in the water. And although the biological aggressiveness of such an environment is small, not every glue is able to withstand such conditions for a long time.

  • Thirdly, the chemical composition of the glue, which glue the aquarium glass, should not be toxic.
The safety of the inhabitants of the aquarium - this is what you should think first!

For example, a construction bituminous sealant or its polyurethane counterpart can reliably connect two glass surfaces of a frameless aquarium, but the harmful substances released over time can severely poison aquarium water. The same can be said about many other synthetic adhesives.

Thus, aquarium glue must be harmless to fish and aquatic plants.

Types of sealants

Immediately, we note: there are a lot of sealants. Some of them are used in construction (for external and internal works), others are used in plumbing works, for gluing various surfaces, sealing joints, etc.

There are 2 main categories: two-component and one-component sealants. Already from the name it is clear that two-component adhesives-sealants consist of two parts - the main component and the additive that activates it.

Single-component sealants, ready for use, are the most common due to ease of use.

On the chemical composition of the main element sealants are:

  • bituminous (used for sealing external surfaces);
  • thiokol (resistant to hydrocarbon-based solvents);
  • polyurethane;
  • acrylic;
  • silicone.
Each of these species is designed for use in specific conditions and only silicone is suitable for aquariums.

Silicone Sealant: Composition and Properties

This type of sealing glue is often simply called silicone. He received the most widespread in everyday life and production due to its qualities and versatility. It is this kind of sealant-glue used in aquarism, which means that you should learn more about its composition and properties.

The composition of silicone is quite complicated. It makes no sense to give the chemical formulas of its components, but in general, silicone sealant consists of:

  • artificial silicone rubber, which is the basis of the adhesive;
  • strength amplifier;
  • dye (if necessary);
  • a vulcanizer that turns glue paste into a dry, elastic material;
  • adheside, providing a strong connection of the adhesive to the surface of any other material;
  • plasticizer, due to which glue-silicone has a high elasticity.

All silicones are classified as acidic and neutral.

There is probably no home craftsman who, squeezing the sealant out of the tube, did not inhale the sour smell of vinegar. So smells acid silicone sealant. On the tube with a similar composition there is a special marking - the letter "A" (acid, which in English means "acid").

Neutral silicone has almost no odor, and it is recommended for bonding and repairing aquariums.

  • Good silicone is durable, moisture resistant and elastic.
  • It retains its properties in a large temperature range from -70 to +70 degrees Celsius.
  • There are special silicone sealants (heat resistant) that withstand a larger temperature range.

The paint on the frozen silicone does not fall, it seems to be rolling down from it. It should also be borne in mind that a new layer of such sealant on the old can not be applied - it just falls off. That is why when repairing a malfunctioning aquarium in the place of a leak, first carefully remove the old sealant, and then apply a new one to the degreased surface.

Selection features

When choosing a neutral silicone for an aquarium, it is important to pay attention to the following points:

  1. Such a sealant is somewhat more expensive than acid. So do not fall for all sorts of tricks of dishonest sellers. And even more to buy "with hands."
  2. It is necessary to check the expiration date of the silicone. Even the highest quality product loses its properties over time.
  3. Aquarium sealant should be colorless. Any dye is an additional chemical load on the aquatic environment.
  4. On the package and the tube should be the inscription "For aquariums" or "Aquarium" in Russian or English.

Aquarium Silicone Sealants: A Brief Overview

There are quite a lot of brands of silicone sealants for aquariums from foreign and domestic manufacturers in the trade network.

Tytan. A large range of these products is presented by Polish companies. For example, Tytan silicones of the Polish firm Selena are in rather great demand in 40 countries of the world. So, Tytan Professional silicone sealant for aquariums

  • completely harmless to fish and other aquatic animals,
  • durable
  • flexible and reliable.

The cost of 1 tube with a capacity of 310 ml does not exceed 350 rubles.

Krass. There is a more budget option: Polish adhesive sealants brand Krass. The price range of this product is from 140 to 200 rubles, and the degree of sealing of the seam is quite satisfactory.

Okyanus kimya. Since 2000, the Turkish company Okyanus Kimya has been successfully operating in the market for this specific product. Despite the relative youth, this company has already found its niche in the market, and the single-component silicones Somafix Aquarium Silicone are in great demand. Experts rate their quality as high.

Soudal - Belgian brand sealants. Almost perfect for gluing and repairing aquariums. Absolutely harmless to fish, with a high degree of adhesion, not containing solvents and dyes - this glue-silicone costs no more than 350 rubles in a retail network.

Domestic silicone sealants quite satisfy all necessary requirements. Of particular note are such popular products as Germent (Lipetsk), Ceresit, and Henkel (a Russian-German company).

Currently, the acquisition of high-quality colorless neutral aquarium silicone is not difficult. It should only carefully review the description of the product and not save too much when choosing it.

Glue for an aquarium. How to glue the aquarium?

Having a home aquarium is very useful. According to psychologists, watching the fish, a person calms down, relaxes. Yes, and the kind of colorful, beautiful fish, quickly moving around the aquarium, always happy!

Today, the pet market is quite diverse. Therefore, beginner fish breeders most often acquire a ready-made aquarium. But aquarists with experience, as a rule, prefer to do them on their own. After all, this is the way to achieve the desired size and volume.

Choosing glass for aquarium

In order to self-glue the aquarium, it is necessary, first of all, to prepare the necessary materials.

It is better to order glasses in the workshop, because the machine performs cutting there (cutting accuracy in this case is higher). When ordering, be sure to clarify that it is necessary glass for the aquarium. It should be silicate, only the highest grade and 8-10 mm thick, since the thinner may not be strong enough and can not withstand the pressure of water.

All glasses are divided into 2 groups - window and polished. The former have a more affordable price, but for the manufacture of aquariums can not be used. The characteristic waviness and greenish tint will have a negative impact on the appearance of the finished product. In polished glass there are no such disadvantages, it provides a perfectly flat surface.

Assembly methods

Before you glue the aquarium, you should choose the method of assembly. There are two of them:

  1. Vertical sides set to the bottom. So glue small aquariums, but this method is rarely used.
  2. The walls are glued around the bottom. This method ensures the strength and reliability of the finished product.

Glue for aquarium

Self-bonding aquarium involves the correct choice of adhesive. Silicone must be present in its composition.

When choosing, you should carefully examine the packaging. Glue for the aquarium should be designed specifically for this product. Its composition should not include antibacterial substances that are detrimental to fish and plants.

Aquarium glass adhesive can be of several colors:

  • colorless;
  • white;
  • black (looks great in large aquariums).

For those who glue the product for the first time, it is better to choose a transparent glue for aquariums (waterproof). For ease of use it is recommended to purchase a special gun that helps squeeze the tool.

Silicone sealants are considered the most universal remedy. Their advantages:

  • long service life;
  • elasticity;
  • the tool provides reliable adhesion to any surface;
  • silicone is easy to use;
  • non-toxic;
  • does not emit harmful substances.

In addition, the glue for the aquarium freezes quite quickly, in just 20 minutes, and after a day the polymerization is finally completed. The seams are very strong. At the same time, silicone retains its elasticity. Before starting to use a sealant, make sure that the surfaces to be treated are clean, dry and degreased.

In addition to silicone, you can use epoxides. However, they are more fluid, harden for a long time and require more thorough cleaning of the surface.

Convenient to use cold welding. This remedy is chemically inert, seizes in a few minutes.

Cyacrines are also good, only when gluing the aquarium between the parts should be small gaps.

If you can not find aquarium sealant, you can purchase a tool that is intended for plumbing or dishes. Only in its composition should not be antifungal additives.

Pasting of an aquarium

The work is carried out in several stages:

  1. To protect the glass from contamination, glue it over with masking tape. From each edge leave a distance equal to the thickness of the glass.
  2. All surfaces are degreased - rubbed with an acetone containing agent or alcohol.
  3. The glue joint should be made as smooth as possible. To do this, put on the end of a little silicone. After hardening, cut it off with a blade, leaving a small ledge above the glass. It will help to make a uniform seam.
  4. Gluing is carried out on a solid and flat surface, covered with polyethylene. First, the glass is glued, which will be located in front, then - the side and all the other parts. Excess glue for the aquarium from the glass should be removed with a cloth previously moistened with a solution of water and vinegar.
  5. After about an hour, the seams need to be smeared with silicone and leave the product to dry. Aquarium is ready to use.

Glue for aquarium

There are situations when there is a need to glue the glass of the aquarium because of a crack, or just make an aquarium yourself. And, of course, the question arises about which glue is better for an aquarium.

How to choose a sealant for the aquarium?

There is a huge choice of sealants on the market, but not every one of them can be used to glue an aquarium, because the glue must be both reliable and safe.

Do not use glue for gluing the aquarium, if it is an acrylic sealant. Such glue does not have sufficient strength of adhesion with glass, besides, it is not moisture resistant.

You should also not use a butyl-based sealant - although it is suitable for gluing glass, it does not have an adequate margin of safety.

Not suitable for glass aquarium and polyurethane, polysulfide or bituminous glue - these types are used mainly in construction.

You can use epoxy sealants, but you need to consider that before using them you need to carry out very thorough cleaning of the bonded surfaces, and they also require a long time to harden.

But the silicone adhesive sealant, being universal, is ideal for an aquarium. This adhesive is used for domestic use, it is flexible, adheres perfectly to any surface, and has a long service life. So when the question arises, what kind of glue is needed for an aquarium, the answer to it is obvious - silicone.

Silicone sealant

Silicone sealant is completely non-toxic, when in contact with water it does not emit harmful substances, which is the key to safety for living organisms in the aquarium. The use of silicone glue for gluing glass aquarium is very convenient because it hardens within 20 minutes, under the action of moisture in the air. The polymerization process is completed completely after 24 hours, the seams being distinguished by super-strength - in order to destroy them, the efforts must be 200 kg.

Being very elastic, this glue allows the seams not to become stiff and not to be destroyed or cracked, this ability of the glue is also important in terms of possible temperature differences, which often happens in an aquarium. When purchasing a silicone sealant, you should choose one on which there are no inscriptions: "antifungal" and "antimicrobial."

Repair aquarium at home

In case of aquarium failure, some ornamental fish owners advise simply to throw it away and purchase another. If the aquarium is small (for 30-40 liters, for example), then it makes sense. And if the house for the big fish? Already 100-liter aquariums are not cheap, even second-hand. Therefore, it is useful to find out how some breakdowns can be fixed at home by yourself.

You need to understand that repairing your own hands is not an easy task. Before starting this work, it is necessary to solve several serious issues:

  • where and how to move the fish, whether it is necessary to evacuate them at all;
  • what materials to use for repairs and where to buy them;
  • how to correct the defect or breakdown and when, after repair, the fish house can be used again for its intended purpose.

How to fix a leak?

Perhaps the leakage of water - the most common failure. One day, the fish owner notices the water on the pedestal, then it begins to drain on the floor, and the wet spot becomes more and more every day.

Leakage can occur for various reasons. When the aquarium is many years old, the sealant with which the joints of the glass walls are glued together (or the joints of the glass and the frame elements) loses its properties. He begins to crumble a little.

It so happens that the owner of the fish itself breaks tightness in any place, removing algae from the glass with a metal scraper. Anyway, the leakage appeared, and it can be fixed with your own hands.

First of all, it is necessary to determine the specific place where the sealing is broken. If the leak is in the upper or middle part of the aquarium, then you need to lower the level of aqua and use a cotton cloth to dry the place.

To prevent the maintenance of ornamental fish from deteriorating, lower the external filter tube to the water level or, if an internal filter is used, lay it on its side.

The leakage should be degreased with acetone, white spirit or alcohol from the outside (on the inside with toxic liquids should not work), dry and apply a layer of special sealant.

After that, during the day, you must wait until the silicone is completely vulcanized, carefully clean the seam, and only then increase the water level to normal.

Glue for aquarium

In industrial production, special silicone glue is used to make a frameless aquarium. Exactly the same should be purchased if a breakdown or seal failure is eliminated independently at home.

Силиконовый клей представляет собой желеобразную массу, которая затвердевает под воздействием влаги, находящейся в воздухе. Примерно за 30 минут на месте склеивания происходит процесс полимеризации массы.

A day after working with this glue, the frozen mass is almost impossible to break, its strength becomes almost the same as the strength of the glass surface itself. This is achieved by the fact that the composition of the silicone adhesive is silicon, which is also an element of glass.

Silicone adhesive sealant is sold in some pet stores and in almost all construction hypermarkets.

For example, sealants of the Soudal, Penosil, Titan or VIK Aquarium Silicone brands are safe for fish, perfectly maintain contact with the water environment, create strong seams. This glue can be carried out as the elimination of leaks, and full gluing. For sealing the cracks in the top cover use the same sealants.


Gluing aquarium

As a rule, gluing is done when the glass is cracked. If the crack is small and is located in the upper part of the tank, then do the same as in the case of the elimination of conventional leaks: the crack is sealed with silicone.

The worst case is when the glass surface is cracked along the entire vertical, horizontal or diagonal. It is necessary to act immediately, as the aquarium water can squeeze out the broken glass at any time.

Where to put the fish?

Immediately need to carry out the evacuation of ornamental fish and other animals. If there is a spare dwelling for aquatic inhabitants (even if of a smaller capacity), then the problem is solved quite simply: the water from the failed aquarium is poured into the spare, the plants are moved to a separate container (a jar, for example), the ground is removed.

You can begin to fix the damage. If there is a thermo bag for transporting fish, then it is also suitable as a temporary dwelling for fish. In extreme cases, you can use the usual three-liter glass jar.

When the glass is completely cracked, it is better to replace it with a new one. That is, requires gluing the aquarium.

Stages of work

The first step - remove the glass. After the dwelling for fish is cleaned and dried, the broken glass is carefully removed. In a frame aquarium, this is not easy to do: from the grooves of the frame you need to gently get as much as possible of the old silicone. As an improvised tool in this case, you can use a nail file. If the aquarium is glue, then inside and outside the cutter makes cuts to the joints.

The second step is to remove the old glue.. When the wall is removed, the entire old sealant is removed, the cleaned surfaces are degreased.

The third step is the creation of a blank. The pattern is cut new glass. Then the silicone sealant needs to be smeared with the edges of the new glass, and the surface of the joints of the structure.

Fourth step - installation. A new glass wall is installed in its place and fixed by wrapping it with a rope or ribbon both horizontally across the entire container and vertically. Before this little sponge silicone gently spreads on all the seams. It is better to slightly moisten the sponge in order to avoid glue sticking.

The fifth step is to consolidate the result. An hour after the first sizing, it is necessary to smear the seams with silicone a second time. Thus, guaranteed reliability of installation of a new wall is achieved.

Sixth step - integrity test. For the complete drying of the glue you need to take 1 day, and after that the aquarium is filled with water for 1-2 hours. During this time, you must carefully check the quality of work. There should be no leakage. At the same time, all foreign substances are washed out of the container.

Seventh Step - start the aquarium. Then the test volume of water is drained, and the ground is laid in the glued-up aquarium, the water for the fish and plants is poured, and the inhabitants of the artificial reservoir return.

In principle, any aquarium can be disassembled and then re-assembled. Some aquarists professionals do this to replace old sealants.

It should be understood that repairing a home for fish requires a lot of time, effort and patience, as well as having a spare home for decorative aquatic living creatures.

What glue is used for an aquarium?

Vladimir

You can really use any silicone sealants, but the cartridge or tube should not be labeled "contains antifungal and antimicrobial substances" or similar. Aquarium sealants are acid-free, so that odorless, vinegar is added to increase the shelf life, it evaporates in 1-2 hours. The rate of polymerization is determined not by smell, but by air humidity, water serves as a catalyst and the higher the humidity, the faster the sealant hardens. Under normal conditions (20 hail, humidity 50%), the polymerization rate is 2 mm / hour, and when the humidity is 95%, the order is 10 mm / hour. In addition to silicones, you can actually use epoxides, but they are too fluid, they harden for a long time and require good surface cleaning. It is more convenient to use cold welding — it is chemically inert, and it sets in minutes. Cyacrines are good, but they require small spaces between the parts, otherwise they just don't catch on.

Jenshen

any silicone sealant (better in a tube for a gun) ... manufacturer of any ... color is black or white (white, translucent looks more beautiful)
the only thing that must be written on the package is suitable for gluing aquariums
aquarium silicone can be distinguished by smell - it smells strongly of vinegar ... the smell disappears completely in 3-4 days, this time is necessary for setting
