The use of plumbing sealant is quite relevant, because no water supply system is immune from unexpected leaks and breakdowns. Therefore, the use of a special hermetic compound will help the pipeline to last longer.

Properties

It is recommended to use sanitary silicone sealants during the installation of the water supply system. When assembling pipes, it is best to immediately use a sealant on the threaded pipe connections, since they are most often susceptible to leakage. The main types of sealants have such positive properties as:

  • most compounds adhere very tightly to various surfaces;
  • a wide range of applications - there are universal sealants that can be used for any plumbing (sinks, toilet bowl, pipes);
  • sealants easily tolerate large temperature changes;
  • they are resistant to UV rays, except for self-adhesive tape;
  • the compositions are very plastic;
  • sealants have a long service life;
  • they prevent the appearance of mold and various harmful fungi.

Among the negative properties of sealants, it is worth noting the high toxicity of some compounds that can be harmful to humans. They can spoil objects in the interior, for example, tiles on the floor or wall. Such problems can be avoided if you work with the composition carefully and in protection, and some material should be laid on the floor and walls.

In the modern market, manufacturers offer a wide range of different types of sanitary sealants:

First of all, it is worth noting liquid formulations… These sealants are based on silicone. The essence of the liquid composition is to apply it to the required section of the pipe, where the sealant spreads and completely repeats the shape of the section. Then the composition hardens and forms an integral protective layer. When choosing such a sealant, you should pay attention to the brand, since not every composition can come into contact with hot water. They can be produced in cylinders or in a tube. And it is also necessary to take into account the high toxicity of the composition. It must be applied very carefully and do not forget about special protection

Adhesive sealant… The big plus of this composition is that it is completely transparent. This is an important criterion for people who want to keep the original appearance of the water supply pipes, or it can be painted in any color. This composition can be used at high humidity. It perfectly comes into contact with any materials and is able to maintain its properties for a long time. Among the adhesives-sealants, the compositions of the company have proven themselves well Soudal and "Moment" … Soudal is one of the most versatile and durable compounds available in a variety of colors. It can be either transparent or white, black, beige, gray and others. The products of the Moment firm have long established themselves in the domestic market as one of the most famous companies producing quality products for installation work

Neutral formulations… Typically, these types of sealants have rubber in their composition. They are flexible and can be used not only in plumbing works. The neutral composition has a high level of water resistance, good and reliable adhesion to various materials and a long service life. Unlike many other formulations, they are not intended for further paint coating

Acidic formulations… The big advantage of such compounds is their low cost relative to other sealants. And also when using such a sealant, mold or fungus will never appear, since the acid kills various harmful bacteria. But such materials are quite toxic and they are not recommended for use on thin pipes, and in no case in direct contact with drinking water. When installing pipes with such a sealant, it is imperative to use protection and avoid contact with exposed skin

One of the sealants is also self-adhesive tape… This option is perhaps the most popular. It is very convenient to use the tape in all types of pipes and sewers. It does not corrode and does not lose its properties with temperature drops. The tape itself consists of a rubber and a protective layer of aluminum foil. This type of sealant is one of the most reliable sealant materials for pipes. Among the negative aspects of this material, it is worth noting its changes when exposed to sunlight. Therefore, it is better to use such a sealant on pipes inaccessible to the sun's rays

Among the sealed materials, it can be noted dry flax… This material has been used for a very long time. But modern types of compounds are several times better than flax, which is prone to rapid decay. Therefore, the technical characteristics of this type of sealant are much less than the current ones. It can be used as temporary insulation of a damaged pipe section

How to apply?

Before applying any sealant directly to the desired section of the pipe, it must be carefully prepared. Usually the surface is cleaned of old paint or rust with a metal-bristled brush. It is also recommended to degrease the area with a small amount of gasoline. After that, you can already apply the sealant itself. If silicone tape is used, then it is wound on the threaded connection, and if any liquid sealant, then it is applied to the site using a special cylinder gun. It is important to remember about safety and not touch the fresh layer of the composition with unprotected hands, because some may contain acid. It is best to use a spatula and work with gloves to form the seams. Different formulations take different times to dry. After an average of 20 minutes, the silicone sealant begins to harden.

How to choose?

There are a number of factors to consider when choosing a sealant:

A situation may arise when the hermetic composition will directly contact with drinking water from the tap. In this case, you should pay more attention to the choice of material. Such a composition must be certified for contact with drinking water

It is necessary to take into account the material on which the hermetic composition will be applied. For pipes made of plastic, metal, or a combination of such materials, you can use a sealing thread designed for the specific material. There are threads that are designed for use in combination pipes. For such materials, you can use a gel sealant that can withstand large temperature differences. Most of these gels are usually white

  • Do not forget about the size of the threads in metal pipes. For fine threads, you can use the same thread or gel that is brown. For coarse threads, liquid formulations can be used.
  • Carefully inspect the packaging of the liquid sealant. There should be no damage on it. Of course, the expiration date should also be appropriate. The spoiled composition completely loses its properties.

Silicone sanitary sealant is a very useful tool for safe and reliable pipeline operation. Today there are many different formulations, among which you can choose the desired option.
