Types and best manufacturers of adhesives for PVC pipes, rules for their use
The use of a special adhesive for PVC pipes achieves excellent results. To achieve a strong and reliable hold, you should pay attention to the choice of adhesive. Today there are many effective tools on sale, each of which has certain characteristics. Strict compliance with the rules for applying the substance is not insignificant.
The main characteristics of polyethylene pipes
When choosing an adhesive, one should take into account the characteristic features of PVC pipes. This abbreviation hides a popular material - polyvinyl chloride. The tool belongs to the group of polymers and has the following characteristics:
- respect the environment;
- good strength after hardening;
- sustainability.
In this case, these factors can be removed. This is due to insufficient resistance to low temperatures. Low melting points can also be a problem. However, PVC pipes are popular with consumers.
The main technical parameters of PVC pipes are as follows:
- High ring stiffness. Due to this, the products are distinguished by good resistance to water hammer. The pipes are characterized by a pressure resistance of 120 atmospheres.
- Good resistance to high temperatures. Even when the pipe is heated to its maximum value, its diameter does not increase by more than 5%. This is not felt at all and does not lead to negative consequences.
- Low temperature resistance. The stiffness parameters of the bonded PVC pipe are significantly reduced when it warms up to 78 degrees. Therefore, experts do not recommend using such material for water with a temperature above 40 degrees.
- Low frost resistance. In case of constant exposure to negative temperatures on the pipes, there is a risk of material destruction. However, this does not mean at all that such products cannot be used in cold regions. To avoid damage to the material, it is worth insulating it.
- Low risk of pipe clogging. This is due to the smooth and even surface of the walls.
- The possibility of using for the arrangement of the sewage system. This is due to the presence of smooth walls and a small thickness of the product.
- Good durability. First of all, this can be achieved due to the high resistance of the material to the action of ultraviolet radiation.
What glue is needed for installation
Special adhesives are often called cold welding. These compounds help to distribute the stresses on the joint, which increases the strength of the material and increases its life.Using glue for PVC or other types of plastics breaks down the polymer with solvents. When the wall softens, the process moves to mounting, which also has a softened base. This method is often called chemical welding.It allows you to achieve 100% seam sealing.
All adhesives are divided into 2 categories:
- Hot melt adhesive. It is designed for mains drainage. PVC and air ducts are glued with the same means.
- Cold glue. The substance is used for cold water supply pipes.
Adhesives are also commercially available and are suitable for soft pipes and hard products. The substance can be of the following types:
- means closing holes up to 0.8mm between the adapter and the product;
- materials that do not seal holes - the distance between the pipe and the fixture should not exceed 0.1 millimeters.
As a rule, large holes appear at a joint in which pipes of an impressive diameter are involved and sockets are used. Small holes are observed in the water supply or heating system.

How to choose the right composition
There are many factors to consider when choosing a product. First of all, it is worth taking into account the degree of bodily harm. Some substances cannot be used in human habitations. The formulations used for welds differ in cure times. This process usually takes 1-4 minutes.
For hot welding, the solidification time is 30-60 minutes. It takes 24 hours to harden completely.
Place of installation of the pipeline
The choice of glue is influenced by the installation area of the pipe. This process is determined by the degree of pollution, liquid temperature and humidity parameters. The ambient temperature should also be considered. Sometimes a situation arises when it is worth choosing adhesives separately for different areas.
Fluid pressure
The bottle of glue should contain information about the pressure that the pipe can withstand. The higher this property, the more expensive the glue. Masters are not recommended to save on composition. It is recommended to compare the level of pressure in the water supply with the value indicated on the package.
Load Features
Piping often moves due to external mechanical factors and internal pressure. With large loads in the connection area, a more reliable compound should be used.
Temperature regime
Some types of glue are great for a cold water supply system, but they cannot be used for sewage, since the drains are characterized by different temperatures.
How to do the job well
Before starting to repair plastic pipes, it is worth making sure that the air circulation in the room is normal. In this case, the temperature should be between +5 and +35 degrees.
Necessary material
It is recommended to select the materials necessary for the proper execution of the work.
To mark
To mark the pipes, it is worth using a marker and measuring tools.
To cut pipes
Special scissors are needed to cut the pipes. It is also allowed to do this with a hacksaw or an electric jigsaw.
For cleaning surfaces
To clean the surface, it is worth using sandpaper.
Degreasing
To degrease the surface, it is worth taking a solvent.
Adhesive composition
To fix the pipes, you need the glue itself. It is also recommended to use a brush with natural bristles and a glue gun.
Procedure
To successfully complete the procedure, a number of sequential steps should be performed.
markup
Before installing pipes, it is worth preparing a project and drawing up a detailed scheme. According to these documents, it is recommended to measure the pipes and carry out their marking.
Cut
The next step is to prepare the segments of the required length. For this purpose, it is recommended to use pipe cutters, however, it is allowed to use other devices. In this case, it is worth making sure that even cut places are obtained. It is recommended to sand the edges with sandpaper.
Connecting elements
It is better to glue the pipes with a special gun.This device helps to gently distribute the substance on the surface. If there is no such tool, it is permissible to use a brush. When applying glue, it should be remembered that there should be no free areas in the chosen place.
Connection parts
To glue the elements of the system, it is recommended to press them well together and leave for half a minute. During this time, the composition will thicken and become viscous. Then it is recommended to postpone the game for a day. It should be ensured that the compression force is high enough. Otherwise, the seal may leak during use.
Cleaning
No matter how precise the application of the substance, it may exceed the limits of the intended area. It is recommended to remove the product immediately, before it hardens. This can be done with a cloth or sponge. It is also permissible to use a damp cloth for this purpose.
Polymerization
It takes 20 to 24 hours for the glue to harden. It is not recommended to touch the system during this time. In this case, it is forbidden to move, separate and reattach the parts. Also, do not run water through the pipes.
Advantages of cold bonding
This type of bonding has many advantages. That is why many masters choose it.
Reduced risk of leaks
Using such a substance to fix sections of pipes helps to connect the elements at the molecular level. The seams are tight. In this case, leaks appear only under the influence of an increase in temperature or pressure.
Minimum labor costs
There are no complicated steps to repair the pipes. This is a simple technique that does not require any special skills.
Low price
All pipe fixing procedures can be done with your own hands. To do this, it is worth buying material and choosing an adhesive composition.
It is not necessary to use a welding machine.
Versatility
The method is suitable for fastening pipeline parts of different diameters - from 6 millimeters to 40 centimeters. It is allowed to use adhesive for fixing the elements of the water supply and sewerage systems.
Additional tips and tricks
When working with such compounds, it is worth applying security measures. First of all, it is recommended to act according to the manufacturer's instructions, which offers a detailed algorithm for performing the work. The use of protective equipment is also important. It is recommended to apply the glue with gloves. Otherwise, there is a high risk of damaging the skin by certain types of glue.
It is recommended to use the substance in a well-ventilated place. This is due to the presence of epoxy resin in the composition. With prolonged exposure to the human body, this remedy can cause nausea, weakness, dizziness.
The hot welding method should be used with care. It is only allowed to use it if you have the necessary skills.
To achieve reliable fastening, it is worth using the adhesive correctly:
- Apply the composition evenly. Otherwise there is a risk of unglued areas. In addition, large irregularities on the surface of the areas to be fixed also cause insufficient adhesion. It should be borne in mind that it takes 2 minutes to create a high-quality fixation after applying the substance.
- It is recommended to apply the composition at the correct temperature. Sufficient time for the composition to cure is also important.If these conditions are not met, the glue solvent will not work.
- Thoroughly mix the components of the product. Otherwise, there is a risk of the appearance of a porous adhesive layer. Air inclusions lead to it.
- Clean surfaces from dirt. If you don't use a special cleaning agent, you won't be able to get a reliable glue solution.
PVC pipe adhesive has a number of characteristics. Properly selected composition guarantees reliable fixation. In this case, it is worth strictly observing the technology of applying the product and observing safety measures.
