Any building structure’s longevity and structural integrity depend heavily on roof waterproofing. Liquid rubber waterproofing is one of the most sophisticated and successful technologies available. This creative method provides a complete defense against leaks, weathering, and water damage to roofs.
The process of liquid rubber waterproofing entails putting a specially prepared liquid coating straight on the roof. This liquid material forms a seamless, impermeable barrier by tightly adhering to the roof’s contours. As opposed to conventional techniques, which rely on joints and seams, liquid rubber creates a continuous membrane that keeps water out.
Liquid rubber waterproofing technology is made with extreme flexibility and durability in mind. After application, the liquid material cures to create a membrane that resembles rubber and can expand and contract in response to temperature variations on the roof. Because of its adaptability to the building’s natural settling and shifts, this flexibility guarantees that the waterproofing will hold up over time.
In addition, the application of liquid rubber is a fairly simple and effective process. Various roof types, including sloped and flat roofs, can use it without requiring major reconstruction. It is an affordable option for both new construction and roof renovations due to its versatility.

Description of the waterproofing process in details
With advancements in construction technologies, roof waterproofing materials are subject to increasingly stringent requirements over time, including high properties and ease of use. This is particularly true when handling roofs with intricate relief and unusual construction, which is quite common in today’s world.
You can use a standard bucket and roller, or you can use special equipment depending on the type of liquid rubber you plan to use.
There is enough brush and standard manual application for a one-component solution. Ultimately, the consistency of such rubber is identical to that of regular mastic. However, spraying two-component rubber requires specialized machinery.
Waterproofing with two -component liquid rubber
We are referring to the airless spraying unit, which simultaneously submits and mixes two components under pressure. They polymerize quickly after becoming open. And without a single seam, they have outstanding adhesion in the end.
Consequently, the process of spraying liquid rubber with specialized equipment becomes relatively easy and enjoyable:
Spraying the roofing is an interesting process in and of itself. Which other roof could you apply quickly and in this manner? Furthermore, only two workers can easily handle the hardest task in this situation.
The precise thickness of the application—neither more nor less—is achieved with the use of specialized equipment. which is crucial because liquid rubber is an expensive substance. The operation of such a device operates essentially in the same way as a traditional spray gun.
It has two tanks: one holds a polymer-bitumen emulsion, and the other holds a chloristocalcium hardening agent. Both materials come from tank tanks, and at the tip, they are combined and fed through a tiny hole that is just thin enough to create a coating that is between 2.2 and 4.0 mm thick. The parts react to one another immediately and freeze in the open air.
Furthermore, the pneumatic and pressure-spraying methods are very dissimilar. The amount of material lost to the environment is greatly decreased here. Put simply, less solvent is added to the composition itself and fog does not form around the sprayer.
Because of all of this, working with liquid rubber eliminates the need for a mask and protective suit, and the coating process proceeds much more quickly because all of the material is focused solely on the roof rather than the air. And a small machine of the Gazelle type can easily house all the equipment needed to run a single brigade, including installation, liquid rubber, and a catalyst.
Liquid rubber is typically black in color, but it can be mixed with water-based or silicon-organic solvents; chemical solvents cannot be used with this material. Though there are now many different kinds of colored liquid rubber available, you can also paint your roof yourself using the VD-Ak-1503 speciality paint, which can also be sprayed on. Another benefit of this is that it provides additional UV protection for liquid rubber.
Skilled roofers are able to apply two layers of color simultaneously, the first layer being applied on top of the other. For what purpose is it used? It has nothing to do with design!
The new layer’s superior quality and whether it entirely covered the old one or some areas were still left uncovered are both very evident. Additionally, you can see how accurately the main material diverges when you spray a different color on top of the previous layer.
When hiring a brigade for this kind of work, keep in mind that you’ll need a license to apply liquid rubber to the roof because it can’t be sprayed without personnel training and there are risks involved.
Waterproofing with one -component liquid rubber
The desired portion of the roof is covered with liquid rubber that has a thickness of two to three millimeters, depending on the task. The coating in this instance is very elastic and can withstand temperatures ranging from -45 °C to +120 °C. Furthermore, how evenly and quickly liquid rubber lays on the roof determines its quality.
Fill in any pits, chips, and cracks on the surface as a first step in surface preparation. If you have the chance, it would be ideal if you could thoroughly clean the roof with pressure-fed hose water and detergent. And how the surface’s levelness will impact the rubber’s homogeneity:
Additionally prepared beforehand by the primer and even mastic of the wall-joint joints and roofing element output:
In order to guarantee that the liquid rubber adheres well to the base, the surface needs to be specified next. Prepare a single component of liquid rubber now, thoroughly mix it, and apply a thin snake.
Next, apply the composition to the roof’s surface using the roller. Apply the second layer as soon as the first layer dries, which should take 8 to 24 hours.
The most important thing is to evenly apply the substance across the whole surface:
Even though the rubber has already been applied, it hardens up to 80% instantly and then again over the course of 48 hours. Nevertheless, you can stroll peacefully on such a roof after ten minutes.
First, figure out how much liquid rubber is needed for the roof. Therefore, 1.35 to 1.65 kg of liquid will be needed for a layer that is 1 mm thick per square meter. Furthermore, a lot relies on the type of base that will receive the liquid rubber application:
- The insulation layer for a wooden and metal structure is 1.50 mm;
- a layer for a concrete and reinforced concrete roof should be from 3.2 to 4.0 mm;
- If you need to cover the membrane roof, then the layer should be 2.0 mm.
If you calculate precisely, you won’t get too much or too little. Liquid rubber is also an expensive material.
Repair of roofing elements with liquid rubber
One of the best materials for waterproofing and repairing roofing is liquid rubber. After all, liquid rubber itself contributes to the strength of the roof’s structure in addition to providing superior hydro- and sound insulation when applied as a coating.
It is possible to apply liquid rubber directly to the older roof layers without first installing anything. which adds value to the material itself because it is suitable for installation on older roofs. The only thing that remains after that is the installation of deflectors to remove the accumulated moisture from the old surface.
One-component liquid rubber works better for localized roof repairs and waterproofing because it can be applied with a roller or brush. Additionally, the finished product’s quality won’t be any worse than a two-component one! You must first thoroughly stir the liquid rubber to prepare it. Apply overlays of special paper or fabric to a repaired surface to give it additional stiffness and unique reinforcement.
Restoration of the old roof: preparation and application
This is how liquid rubber waterproofing actually works in real life. Two or three layers of one-component rubber should be applied, and each one should be dried beforehand:
When waterproofing, rubber should only be sprayed or applied to dry surfaces, and all work should be done at a temperature of +5 °C.
Local repair of the roof and waterproofing of adjacence
Use reputable imported materials like Premier Rubber Membrane if the quality of the liquid rubber you’re using for repairs worries you. This is the composition of Cantex Coatings Ltd., a Canadian company; it is entirely made up of non-flammable liquids and contains no organic volatile compounds.
This product’s dense rubber coating and dark brown color will tell you what it is. It will have exceptional resistance to mechanical deformations, absolute water and vapor permeability, and a particularly high elasticity of roughly 1500% after it has completely dried.
The manufacturer also states that these properties, even with continuous contact with water, will be repaired for over 25 years:
As an illustration, consider liquid rubber applied to the repair area in two layers (up to 2 mm)—four layers of roofing material based on waterproofing properties!
Liquid rubber roof waterproofing is a contemporary and practical way to keep your house dry and safe from water damage. With the help of this technology, a flexible, seamless membrane that clings firmly to the roof surface and forms a strong barrier against leaks can be created. Unlike conventional techniques, liquid rubber ensures complete protection on a variety of roof types, including sloped and flat roofs.
The simplicity of application of liquid rubber is one of its main benefits. It can be applied to the roof in two ways: rolled or sprayed. It will cover joints and seams seamlessly and mold to irregular shapes. By doing away with joints and seams, which eventually become weak spots, this technique lowers the possibility of water seeping through and increases the roof’s lifespan.
The adaptability of liquid rubber in various weather circumstances is an additional advantage. Its efficacy is not compromised when applied in hot or cold temperatures. After application, it creates a strong membrane that, in response to weather variations, grows and shrinks while retaining its integrity over time.
In addition, liquid rubber is less harmful to the environment than conventional roofing materials. It doesn’t release any toxic fumes during or after application, nor does it contain any harmful chemicals. This promotes a healthier indoor and outdoor environment by making it a safer option for homeowners and installation teams alike.
To sum up, liquid rubber roof waterproofing is a state-of-the-art method of preventing water damage to your house. It’s a popular option for contemporary roofing solutions because of its easy application, resilience, and environmental advantages. For enduring protection and peace of mind, liquid rubber provides a dependable choice, whether you’re thinking about new installation or roof maintenance.
