Brand of waterproofing roofing TG 350 for roofing: Specifications + Photo and Video

Brand of waterproofing roofing TG 350 for roofing: Specifications + Photo and Video Waterproofing roofing paper TG 350 GOST. Waterproofing is one of the most important stages of construction, and this applies to both foundation and roofing works. Recently, more and more materials are being developed that do an excellent job of this task.

One is such material as roofing. But does this material really do the job well? This will be discussed in this article.

General information

Many of those who have not previously been involved in roofing or waterproofing, will still be able to visually determine exactly how the roofing board looks. This material is very similar to roofing material, and not only externally, but even in composition. It is based on thick cardboard, therefore it differs in a certain level of fragility.

To increase the strength of waterproofing roofing roofing TG 350, impregnation is made with resins, which are mined from coal. Please note that the top layer of the material remains soft enough.

To level this deficiency, sprinkle with sand or any other mineral substance on top.

When passing through the bath, it is only perfectly soaked. This is possible due to the special container size. The width is 1.2 meters, which is enough for the sheet to enter the bathroom completely.

The thickness of the resin, into which the roofing is immersed, is 0.8 meters, and this is enough for a small thickness of the cardboard. But the impregnation temperature is +100 degrees. When the temperature drops, the roofing paper is rolled up.

To prevent it from sticking together, use a special powder.

It is convenient to store the roofing paper on a roll, since in this position it will not bend or be damaged. Before rolling, the roofing is dried with hot air.

Varieties

There are many varieties of roofing roofing, which mostly differ in the amount of bedding and quality. The material on which the coarse fraction is applied is used only for roofing work. It is laid on the roof as a second layer at a slight angle.

The bedding is applied on 2 layers, with the first on the front side and the second on the bottom. Please note that on the top of the roofing paper there is coarse sand and fine-grained mineral powder on the inside. If you need this particular variety, then look in the store for material marked TKK 350 and TKK 400.

These brands have slightly different physical properties. Both the first and second types in the amount of one roll can cover areas of 10 m 2 .

But in the first type the weight is 2 kg more, while in the second type it is 25 kg. The temperature for performing work should be about +25 degrees. It is at this temperature that the roofing will be elastic and easily take on any surface shape. Both of these options are made according to GOST.

And the last type of roofing that we will consider is used for other purposes.

This is a waterproofing roofing sheet TG 350 GOST.Its main advantage is not too high a price, unlike its competitor. This type only does not have a mineral powder, which determined the scope of this type of material.

TG roll material is perfect for waterproofing foundation and roof. The production of the last variety of roofing roofing has certain regulations, which are spelled out in GOST under the number 10999/76.

The manufacturer must carry out all prescribed tests after manufacture. One of them is the level of moisture absorption. To do this, the material is placed in water for 24 hours, and if during this time the material has absorbed more than 1/4 of the water, then it is not suitable for use as a waterproofing agent.

Important! Each roll has a central opening through which it can be transported and unwound during stacking.

Roofing material or roofing felt - that is the question?

Although both of these materials have similar characteristics, they cannot be called the same.

The fact is that they differ even in the impregnation they use for cardboard. If we talk about roofing material, we are talking about resin or bitumen, which is made from oil products. In an improved version of roofing material, polymers are added to the resin, which significantly improve the quality of the material and extend the service life. Above we have already said that roofing paper is impregnated not only with oil products, but also with tar based resin. Note that roofing felt is slightly stronger than roofing felt.

It has excellent insulating properties. The material is also considered to be vapor-permeable to some extent.

Advantages and disadvantages

Taking into account the above factors, you can easily make a list of advantages and disadvantages. The first group includes:

  • Light weight.
  • Low cost.

  • Easy to install.
  • Resistance to chemical components.
  • Excellent insulator.

If you do not plan to hire specialists or just a team of workers, you can still lift the roofing roll on your own, since it is relatively lightweight. He also tolerates chemical exposure well.

This is especially true for those elements that fall out with precipitation. Do not worry that the roofing will be destroyed due to precipitation. The material is also minimally susceptible to biological effects, which may be due to bacteria in the ground.

Of the minuses, we single out:

  • Small tensile strength.
  • Short service life.

  • Exposure to temperatures.

In comparison with modern materials, which are made on the basis of fiberglass or fiberglass, roofing paper has the lowest strength, and therefore you should be careful when laying it. As a result, the material has a short service life, as it is constantly exposed to stress. It only has properties to soften even at low temperatures, and for this reason it cannot be left under the scorching sun.

Please note, that if you do not follow the procedure for laying the material as an independent roofing covering, then its service life will not exceed one season.

As a result, you will have additional costs for the roofing material that you need to repair or replace the old roofing.

Scope of application

Brand of waterproofing roofing TG 350 for roofing: Specifications + Photo and Video Roofing board is a material from the budget rulers, therefore it is most often used as a rough material or as a lining when performing a certain type of work. It can also be used as a temporary replacement for roofing material, which will be laid later. It is perfect for finishing a basement or foundation, but then you need 2 layers for laying. One of them must necessarily be a waterproofing TG 350, which is laid on the plane itself.

In order for this layer of material to be protected from mechanical effects, lay the second layer of roofing roofing, but already with a coarse powder, which must be outside.

Good advice! If you plan to use the material only after a year, we advise you not to buy it in advance.

For storage of roofing roofing, it is imperative to choose a dry room, and at the same time arrange the rolls strictly vertically so that the coils do not crumble and stick together into one continuous mass.

Laying options

You can easily install the roofing roofing with your own hands. To do this, you need to make a thorough inspection of the surface to be processed in advance.

After that, you need to remove all debris and dust so that this does not interfere with good adhesion. It will be nice if you treat the planes with a primer. This composition can be easily made using kerosene and bitumen. When everything is dry, installation work can begin. Laying and its sequence on a plane was described earlier.

Please note that the roofing sheets must be fixed with overlapping seams. Each of the next layer should go to the last one by about 9-10 cm. This will make it possible to provide a high level of waterproofing properties.

TG 350 waterproofing roofing sheet can be glued to hot or cold mastic, and it is important to take into account how the material will behave at high temperatures. Sometimes the mastic is warmed up to +84 degrees before use.

The second layer of waterproofing from a layer of roofing tar paper with powder is laid so that the seams of the first floor are completely covered. This type of material should also be glued onto mastic.

For roofing works, roofing only is used only as a lining for the main material, and in this case it should also be glued to the surface on a layer of mastic. If we are talking about a concrete slab, then for laying it should be leveled and all imperfections in the form of an influx and potholes should be removed. If you do not do this, the material can easily tear and cease to function.

The top layer of roofing material / glass insulating material is laid by fusion, which gives all the chances to achieve an ideal level of adhesion.

Still sometimes roofing paper is used as an insulator when laying a soft roof / flooring on a wooden crate. But in this case, the sheets of material are laid from the bottom up and the overlap is not 10, but 15 cm. They are nailed to the crate using ordinary roofing nails that have a wide head. Sometimes adhesion to a layer of bituminous mastic is acceptable.

But in this case, the process will not only take more time, but a certain period will also be needed for the composition to dry out and polymerize to obtain the desired level of strength.

Conclusion

As you can see, roofing board has the right to be and is successfully used in construction. In many cases, it is used in the construction of various household buildings. This is due to the fact that for residential buildings you need to select materials that will last much longer. Before starting the installation, the rolls need to be rolled out and cutouts are made for those elements that will be on the surface.

After that, the roll should be re-rolled and unwound as the adhesive mixture is applied. Sometimes the ideal option is to roll out a roll of material from the middle to the edge of the roof or other surface.
