The trend of our time: liquid roofing

One development in particular sticks out as we consider roofing solutions going forward: liquid roofing. Due to its adaptability and practicality in dealing with contemporary roofing challenges, this novel approach has been gaining popularity. Using a liquid coating applied over pre-existing roof surfaces, liquid roofing creates a seamless, waterproof membrane over time. This technique not only makes roofs more durable, but it also offers new constructions and roof renovations an affordable option.

Liquid roofing has the advantage of being able to adapt to different types of roofs and materials. A continuous barrier against water infiltration can be formed by applying liquid roofing evenly, regardless of the shape, curvature, or intricate details of your roof. Because of its adaptability, it is especially well suited for intricate architectural plans where conventional roofing materials might be challenging to install or maintain.

Liquid roofing has many practical advantages, but it’s also eco-friendly. Being low in volatile organic compounds (VOCs) means that many formulations have less of an effect on the quality of the air both during and after application. Furthermore, some liquid roof coatings’ reflective qualities enhance energy efficiency by lowering heat absorption, which can save cooling expenses in warmer climates.

Because of its longevity and low maintenance needs, liquid roofing provides property owners and managers with long-term financial savings. These coatings are resistant to UV rays and harsh weather once applied, so they won’t peel or crack. For those wishing to make a sustainable investment in the infrastructure of their buildings, its longevity translates into fewer repairs over time.

Liquid roofing is becoming a popular choice in today’s construction industry because of its longevity and adaptability in providing building protection. Liquid roofing systems, as opposed to traditional roofing materials, provide seamless coverage, are easy to modify to fit intricate roof structures, and require less upkeep. This creative method lowers installation time and energy consumption, improving building longevity while also offering affordable solutions. Liquid roofing’s capacity to reflect sunlight and increase energy efficiency is a perfect fit with eco-conscious building practices, as sustainability becomes more and more important. Adopting this trend is a move in the direction of more intelligent, durable building solutions for the modern day."

What is a bulk roofing

A waterproofing material known as liquid or bulk roof is made of bitumen and latex combined with water and technological additives. The fluid on the roof instantly becomes a strong, continuous layer because of its viscosity.

Any size or shape roof can use the material that turns from a liquid to a firm state.

The waterproofing process moves more quickly the larger the processed area. Even the roof’s relief, or the existence of chimneys and visors, is not slowed down by the liquid roof device.

The scope of liquid roof

The application of liquid waterproofing material is remarkably broad because it sticks firmly to any surface.

The bulk coating, in contrast to roofing material and membrane, adheres flawlessly to the roof’s base in both cold and preheated conditions.

Bulk coating is typically applied to the following types of roofs:

  • reinforced concrete;
  • slate;
  • metal;
  • wooden;
  • tiled;
  • Rolled.

The advantages and disadvantages of the bulk coating

The benefits of liquid roofs are well-known and include:

  • Seamless coating;
  • elimination of all cracks and holes;
  • high elasticity;
  • almost unlimited service;
  • lack of a negative reaction to ultraviolette;
  • the possibility of storage in liquid form in hermetic capacity;
  • the ability to adapt well even with an old coating;
  • minimum consumption (1-3 kg per 1 m 2);
  • device without the help of electric energy, water or source of fire;
  • harmlessness;
  • good insulation of the roof from moisture;
  • security from damage in contact with atmospheric precipitation;
  • normal tolerance of both cold and heat.

The following are the liquid roof’s drawbacks:

  • dismantling only by mechanical method;
  • fear of oil -containing solvents;
  • a significant cost of the device for the device of sprayed liquid roof (from 100 thousand rubles);
  • installation only at a temperature of at least 5 ° heat.

Types of liquid coating

Using the surface processing method, liquid roofing material is sprayed, stained, and applied in bulk.

Invalid technology

The bulk coating calls for manual action from the master. He must apply two compositions to the base beneath the liquid roof: a bitumen emulsion initially, followed by a primer once it has dried. This should cause a film to form that is between one and two centimeters thick.

A 2 or 3 mm layer of liquid waterproofing material is gradually poured into the prepared area. If a construction roller is used to distribute the waver coating layer across the roof area, the result will be even coverage. On top of a polymer-bitumen mixture that has solidified, it is advised to apply an additional layer of liquid material.

A liquid roof that uses bulk application technology dries in a matter of seconds. Experts advise against rushing to apply a second layer of waterproofing material until after a five-minute break.

Although the processed surface can be made perfectly even using bulk technology, pitched roof waterproofing is not a good use for it.

Coloring technology

After priming the surface, the liquid waterproofing material staining of the roof is done by hand. The first (30%) layer is made of a rubber and water mixture. If the street thermometer indicates a minimum temperature of 20°C, the composition is applied with a brush or roller and allowed to dry for an hour.

The amount of time needed to cure the paint coating’s first layer is doubled or tripled in colder temperatures (+5 °C).

A liquid waterproofing substance that isn’t diluted with water forms the second, 3 mm thick coat of paint. At the base of the roof, the composition is smeared in a direction perpendicular to the direction in which the initial layer of liquid roof was applied. A broad spatula is used to align the coloring coating.

In an attempt to reap two benefits, they turn to staining technology. In addition to decorating the roof, the paint coating shields the house from harmful weather conditions.

Pomping technology

According to pomping technology, the liquid roof device involves spraying the composition using an airless pumping apparatus that can run both an electric and gasoline engine.

The free pumping equipment needs to be purchased or rented. Therefore, you need to budget for additional costs when selecting the spraying technology. The equipment from the Pazkar RK-10, UND-01, Technoprok B-21, and RX-27 brands is the highest quality.

Two containers are connected to the installation right away. To hasten the liquid coating’s solidification, one of them should be filled with a bitumen-polymer emulsion and the other with calcium chloride.

Two substances combine as they go through the nozzle, settle on the roof’s surface, and form a polymer-biomatic waterproofing membrane.

Liquid waterproofing is applied to flat or, on the other hand, significantly tilted roofs using the pomping technology. The composition is evenly spread across the surface during irrigation.

It turns out that spray technology works best when you have a large area of the roof to waterproof. The calculations demonstrate that a large area consumes liquid material more economically than a small one.

Roof liquid waterproofing algorithm

Three stages make up the conditional division of the liquid roof device process:

  1. On the label of liquid rubber, information is found how many kg of this material falls on 1 m 2 . Roof area is divided into the identified number. So get the required amount of liquid rubber. And to find out how much tanks of the composition for waterproofing the roof will be needed, the total number of kg is divided by the amount that is placed in one container from under the material. When applying liquid rubber in cold form and in two layers of one kilogram usually enough for 3 m 2 . But these data are only approximate, in any case of waterproofing material, it should be bought 10-15% more than necessary.
  2. The base under the device of a liquid roof is cleaned of dust with a damp cloth or stream of compressed air and thoroughly examined. The garbage is removed, and the identified cracks are sealed with putty or a mixture of water, sand and cement. Further work is put off at the time when the surface of the roof is completely dry.
  3. By choosing a hot method of applying liquid rubber, the composition is heated to 22 °, and then immediately cooled so that its temperature drops by literally 7 °. After these manipulations, liquid rubber is promptly poured and distributed throughout the roof. When applying waterproofing material in a cold state, a wide brush or painting roller is used, which will help to scrupulously smear the roof and create a neat layer of 3 mm thick. In hard -to -reach areas of the roof they act with a spatula or a narrow brush.

Ten minutes after the first liquid waterproofing layer is applied, the second layer is created on the roof. The viscous material succeeds in solidifying into a film during this time. A third layer of liquid roof construction should adhere to the same guidelines.

The brands "Technonikol," "Fast Repair," "LKM USSR," "Technoprok," and "Euromast Plus" are among the many varieties of liquid rubber that are trustworthy.

"Fast repairs"

"Fast repairs" liquid rubber is a one-component polymer primer. Any weather can be used with this material; the processed surface’s condition won’t need to be taken into consideration.

Customers claim that the waterproof film from "Technonikol No. 33" mastic is extremely resistant. Even if the roof deforms, it does not deteriorate.

"LKM of the USSR"

"LKM USSR" liquid rubber is a type of one-component acrylate liquid waterproofing material. The mixture is applied specifically to protect against moisture and to repair the damaged roof.

Either a manual or mechanical method is used to arrange the roof made of the liquid material of the LKM USSR brand. The completed coating exhibits strong elasticity and resilience against all types of weather conditions.

"LKM of the USSR" liquid rubber sticks to any surface with consistency. In contrast to other brands, the composition can effortlessly switch from its original white color to any other by simply inserting a natural plug.

We ordered the liquid roof of the LKM of the USSR, we came across a little at first with it: we started to apply – rain watered, blurred it, turned out to be a great primer)). Then the truth was dry, she froze after 30 minutes. Another layer was applied – and ready.In general, the pluses: the simplicity of application does not smell, does not miss the water at all, elastic, stretches well, but at the same time, on the basis it is very strong, walk and carry a heavy cart without fear of its damage, it is also easy to wash the tool. Cons: you can apply only at plus temperature and medium surface moisture.
