Why do we need liquid roof
An unfavorable climate that reigns in many regions of our country leads to the fact that many building materials over short time lose their operational properties. Low temperatures and sharp temperature fluctuations are able to deform the roofing coating. Thus, rubberoids and other similar means quickly come into disrepair, losing the ability to waterproofing.
Among modern, better and durable materials, you can select liquid rubber for the roof. It is applied to the surface with a "cold" way, that is, without warming up, which will noticeably simplifies the process of work. Such a roof is distinguished by increased strength, it is seamless, elastic and can serve a much longer sheet and rolled waterproofing. With this quality, the cost-effectiveness of the coating is connected, although it is noticeable more than the same referencerad. But, unlike Ruberoid, it will not have to be repaired every 1-2 years, the liquid tires serves decades without bursting, not cracking and not breaking.
Advantages of waterproofing roofing liquid rubber
- Liquid rubber allows you to create a monolithic coating on the surface without a single seam. It does not only have butt, adhesion and seams, but also microcracks, through which moisture can get into roofing pie and spoil the following materials.
- Most rolled materials are mounted on the roof by heating. If you do not heat the leaf itself, then you will definitely cast the mastic on which it is glued. And on some construction sites, due to certain reasons, the use of fire is not allowed. With liquid roof, which is applied to the surface with the "cold" way, such a problem will not arise.
- Liquid rubber has increased elasticity, which allows it to carry the temperature differences, the range of which is from -50 ° C to +100 ° C. Even under such adverse conditions, the material is not peeled, not deformed, does not crack and does not even soften.
- Fast repair of liquid roof - another of its undoubted advantages. Even if damage is formed on the surface for some reason, they can be patched with the same composition, but in the case of a roll material you have to change the whole fragment of the sheet.
- The repair of the liquid roof is simple and because it is very easy to detect the leakage and immediately close it. On rolled damages are not as noticeable and are designed more difficult.
- Liquid rubber for the roof allows you to work with complex objects and areas, such as drainters, mines and vertical elements. Apply it to such zones is much easier, but the rolled material will have to lift and lay in a certain sequence.
- A similar type of waterproofing is characterized by high strength, moreover, it can be further increased by adding a special spree between the coating layers or the glass-grid.
- In any case, the rolled materials cannot be kept on a wet roof, otherwise they will quickly exhaust. With liquid roof, this requirement is not necessary, since the rubber is perfectly engaged in almost any surface.
- Liquid hydroizol for roof can be used in combination with rolled means.
- Liquid rubber is used for waterproofing surfaces not only outside, but also indoors, and its installation is carried out much easier and faster than roll coating.
- The water-repellent properties of the material under consideration are much higher than other analogues.
- The liquid waterproofing of the roof has a small mass and does not have a noticeable load on the overlap of the building. The consumption of rubber is approximately 1.5-2 kg per 1 m², while a layer of 1.5-2 mm thick is created on the surface.
- The simplicity of work with the material is that you do not need to cut sheets and perform a certain sequence of laying, creating reinforcing layers. With the help of the spraying method with liquid rubber for 1 day, an area of \u200b\u200b600 m² can be covered.
- The roof, waterprojulated in this way, you later can paint in any hue.
- Through such a mastic very quickly. The durable grip with the base occurs faster than 1 minute, and after half an hour, the roof can withstand minor physical exposure, for example, it can be walking.
- The liquid roof is not afraid of ultraviolet radiation, it is resistant to most chemicals, is not damaged by salted water, alkaline and acidic compositions, gasoline, oils. It does not have microorganisms and mold.
Liquid waterproofing for the roof requires minimal labor and time costs, and although it is more expensive than many other materials, the durability of use with one will pay off all expenses.
Spheres of using liquid polymer roofing
- Most often, waterproofing of this type is used in the construction of residential and industrial facilities. Since the liquid polymer coating has increased strength, it can be used on the roofs, which will later be actively operated. For example, you can equip the parking for cars on such a roof, create a garden, recreation area, etc.
- With the help of such mastics, you can restore soft roofs.
- Liquid rubber is convenient to use for waterproofing complex areas: ventilation channels, chimneys, parapets, pipe output places, etc.
- With such compositions, you can water the balconies and loggias, as well as visors.
- Polymer mastic are indispensable on industrial buildings, especially where there is no fire when laying rolled materials.
Types of liquid roofing
By the number of components, which are part of the material, distinguish such types of liquid rubber:
- One-component - represents a multicolor mass that does not need advance preparation and can be used immediately.
- Two-component is a composition that includes the basis and a special hardener. Its components are mixed before applying.
According to the application method, the material may be:
- Pause - applied to the surface with a bruster or roller, like ordinary paint. Most often it is a liquid or pasty mass.
- By sprayed - such rubber is a liquid that is supplied through a special installation and quickly spans on the working base.
- Empty - this mass is prepared immediately before work, then poured onto the roof site and rolls.
When sprayed or a bulk method, rubber penetrates the smallest slots, pores and cracks, closing them from moisture penetration and creating very durable and reliable protection.
Methods for applying liquid waterproofing
Mechanized method
Depending on the presence of materials, tools, devices, as well as on technical capabilities and type of coating, are determined with the method of applying liquid waterproofing. This can be done manually or enjoy a special airless injection unit. It should be noted that you need certain skills and skills to work with it, and if you are not sure that such work can be forces, it is better not to risk and put the coating manually.
The installation is convenient because in the process of work, it immediately mixes all components of the mastic in the desired proportions, and then supplies them as a sprayed mass. High pressure that is approximately 18 atmospheres, allows the solution to penetrate the smallest pores and microcracks. The polymer mastic is seized on the surface almost immediately after applying.
Mobile aggregate allows you to noticeably speed up the work process. It is also useful in that minimizes the consumption of the material and makes it the most economical. The thickness of applying mastic directly depends on the type of roof. The membrane roof requires waterproofing with a layer of 2-3 mm, a metal and wooden coating can be treated with a layer of 1.5 mm, and for concrete the ideal indicator will be 3 mm and more.
The process of creating a liquid roof consists of such a sequence of actions:
- Initially, the roof is measured and the number of necessary material is measured on the basis of the surface.
- Then buy goods paying attention to its quality. It is advisable to buy polymer mastic proven manufacturers in specialized sales points.
- After that, the surface of the roof is prepared for work, and then mastic is applied to the base.
- The tightness and flatness of the layer are verified and if necessary, the shortcomings are corrected.
About the desired amount of material is better to talk separately. Mastics should be enough for the processing of the whole roof. If it is not enough, there is nothing terrible in this, but it is inconvenient to buy material in the process of work. At the same time, it is not necessary to make a large stock when buying, since mastic is expensive, and this will entail unnecessary additional costs. To find out for sure how many rubber you will need, measure the roof and calculate its area. Then learn the approximate consumption of the material that is specified on the package. Based on this data, count the amount of mastic you need. If the packaging does not contain the necessary information, then follow these figures: 1 kg of substance is usually enough to cover 4 m² of area, if you apply it in 2 layers. To your calculations, add another 10% and purchase the material in this amount.
Mastic applying manual way
If the roof is small, you do not have a mobile installation, then mastic can be put in hand. For such work, a brush, roller or spatula is used. Immediately disclaim that the process is this time consuming and long, so you need to calculate your own strength and time. But manual application is available to each and does not require any special skills and skills.
The process of work is as follows:
- Mastics are better in good weather, when it's not too hot, there is no rain and fog. The ambient temperature should be not lower than +5 ° C.
- The preparation of the working foundation provides for the removal of all foreign objects from the surface of the roof, as well as cleaning it from garbage and pollution. If on the basis there is a fragile and peeling layers of the former coating, they should also be eliminated. Noticeable defects are corrected using a cement-sandy solution or another means suitable for this type of roof. If you restore the previously applied rubber coating, then clean the treated zone with coarse-grained sandpaper, then cover the plot of mastic and correct it in the rest of the surface.
- So that the tires are guaranteed concluded with roofing, oil and other fat stains should also be removed.
- Cold mastic is applied to the surface with a wide roller or a large brush, creating a layer of 3-4 mm.
- As a rule, waterproofing is applied in 2 layers. The first layer is allowed to dry for 10-15 minutes, during this time the rubber is completely polymerized and carefully concludes with a working base.
- After that, perform the second layer in the same way. In some cases, there are 3 coating layers, leveling all height differences in the process of applying.
- On top of the finally frozen mastic, you can apply the finish coating.
