Bitumen plastic is widely used in construction and has an impact on cost, operational characteristics, durability, and coating material selection. What kind of bitumen plastic is required? Making the best decision is challenging because there is a lot of variation in the building materials market. It’s important to understand the purpose of the product in order to avoid mistakes.

We examine the useful advantages and uses of mastic bitumen cold application at "All about the roof." This technique offers a straightforward, long-lasting way to waterproof and seal roofs, revolutionizing roofing. This mastic bitumen offers outstanding flexibility and weather resistance by applying itself smoothly to a variety of surfaces through the use of cold application techniques. It guarantees longevity and cost-effectiveness while maintaining ease of application without the need for heating, making it perfect for both new construction and repairs. See how this creative method’s dependability and adaptability improve roofing solutions.

Composition, types and types

All different types of composition-based mastics can be categorized by:

1. One -component. The properties of the coating are manifested after the evaporation of the secondary components of the product, that is, complete solidification.
2. Two -component. The properties of the material are manifested only after the hardener is added to it.

Among the primary varieties is mastic made of bitumen:

Two kinds of mastic should receive particular attention among the range of solutions:

Hot bitumen plastic

This is a uniform plastic mass that is heated to 180 degrees before use and is made of astringent fillers and products used in oil refining. The mass is applied to the previously primed surface after heating.

Cooing causes the mass to solidify into a highly elastic coating.

The following are hot bitumen mastic’s primary benefits:

• lack of shrinkage;
• dense structure;
• The ability to use at low temperatures.

Among the primary drawbacks are the elevated danger of fires and substantial labor expenses.

Labeling

The letter does, however, mention the addition of herbicidal additives and an antiseptic to the mass’s composition.

Cold use bitumen

Because it is so simple to use, this kind of bitumen plastic is the most widely used, confirming its many benefits:

• There is no need to heat the mixture, which facilitates its application.
• The composition of the mastic can include dyeing pigments to achieve a wide color scheme.
• The desired consistency of the mixture can be obtained thanks to the addition of a solvent to it. This breeding method is suitable for cold mastic, which it includes.
• The mass is transformed into a waterproofing layer that is not afraid of the UV radiation and temperature differences that is resistant to atmospheric influence.
• When using cold bitumen mastic, the duration of the service life of structures and structures processed by it increases.

Two groups of mastics for cold use are distinguished:

• made on solvents;
• on water -based (bitumen emulsions).

Areas of application

This kind of mastic has a wide range of applications. Bitumen materials are most frequently utilized for the following tasks:

• installation of a new roof;
• Repair of the old roof: restoration of the waterproofing layer, leveling;
• waterproofing of pools, artificial reservoirs, fountains;
• installation of tile coating in places with a high humidity; protection of metal products from corrosion;
• for waterproofing the roof in places of adjacence to parapets and ventilation ducts;
• installation of a protective layer for the foundation;
• laying of roll waterproofing;
• installation on the mastic of heat -insulating plates;
• waterproofing in buildings with poor ventilation, its absence, excessive humidity.

Advantages and disadvantages

I want to draw attention to the advantages and disadvantages of bitumen mastic. The composition is highly well-liked because of its many benefits:

• To perform high -quality work with bitumen compositions, construction experience or special tools do not need construction experience.
• Such compounds have good elasticity and deep penetration into the structure of the material.
• Cold mixtures are very often used during internal isolation of the premises due to solvents that make up the mixtures.

There are additional drawbacks to using cold-use bitumen mastic:

• It has no resistance to ultraviolet rays;
• low combustibility;
• High -quality cold bitumen is more expensive than hot.

It is important to take these characteristics into account when selecting a mixture for various plane repairs.

The main recommendations for working with bitumen compositions

When the temperature is at least -5 s and the weather is clear and dry, waterproofing work should be done.

Multiple layers are used to process vertical planes. Compound Apply parallel stripes of the same thickness starting at the bottom.

The bitumen mixture is kept out of direct sunlight and in closed containers. Use the special nozzle-mixer drill to thoroughly stir the composition.

It is worth mentioning that the mechanical method of applying the composition is not used very often. Because of the material’s high viscosity, use a sprayer. Make sure a tank or roller is ready in advance so that you can work at your convenience. A regular paintbrush is used to apply the bitumen primer.

Wash the tools in the white solvent or spite after the work is finished.

Bitumen mastic of cold use – scope of application

A waterproofing layer is actively created in construction using bitumen mastic. Tell the difference between hot and cold. The second type is prepared for use; it can be further divided into solvent-based and emulsion subtypes based on how they are applied.

What it is

It is a thick mass that depends on whose asphalt. Additives such as chalk, limestone, dolomite, and other products from waste processing may be included in this material. It has outstanding antiseptic qualities that shield it from biological deterioration due to the antiseptic silica sodium present in it.

The content is of excellent quality. The following are its attributes:

• Excellent waterproofing;
• Good elasticity;
• High -quality adhesion.

Application area

Bitumen mastic is applied in the situations listed below:

• When arranging and repairing various types of roofs;
• Waterproofing of various structures (foundation, basement and ceilings);
• Waterproofing of wet rooms;
• Connection of the joints when laying flexible tiles and similar materials with a bitumen base to the surface of brick, concrete, metal, wood, ceramics.
• The device of the protective layer when creating a roof.

Application technology refers to using this material without heating it beforehand. This enables you to operate in any environment.

Advantages and disadvantages

There are several advantageous aspects to the material. Among them are:

• Confrontation between fungi and damp;
• When exposed to humidity and paravzdutia, does not occur. The surface of the film remains continuous;
• Resistance to cracking, material strength is very high;
• Simplicity of use. It is easy to work with mastic, for this you do not need special knowledge and skills. The work methodology resembles oil painting;
• Easily withstands various temperatures;
• Effective protection against moisture of wooden and other surfaces;
• Good elasticity of the coating allows you to work with it and operate without fear to damage the structure;
• Many species have an affordable cost;
• Durability;
• Work can be carried out at any time of the year;
• Easy transportation;
• Resistance to various influences, including chemical.

The following are some of this material’s shortcomings:

• In the process, you should wait until it freezes. Otherwise, its quality will not correspond to the declared characteristics.

Material consumption

Both the kind of work for which it is used and the kind of material itself determine how much is consumed:

• For gluing, an average of 0.8-2 kilograms of mastic per 1 square meter of area is used, the consumption depends on the type of base material;
• When installing the waterproofing layer, 2.5-3 kilograms per square meter are required when creating a layer of 2 millimeters thick;
• The consumption of tile mastic on the end parts of the tiles with a width of 10 centimeters is 0.1 kilogram per 1 linear meter, 0.7 kilograms for adjacent to brick surfaces, 0.1 kilograms per linear meter are spent to glue the joints of the lining carpet;
• When creating a mastic roof per square meter, 4 to 6 kilograms of mastic will go;

Take note! It makes no sense to increase the consumption of mastic. Make the glue better so that it won’t work.

Roofing work using mastic

It is important to fully mix the roof bitumen mastic throughout the capacity before beginning any work. It can be diluted if needed. Nephras or white spiteen, gasoline, solvent, and bitumen emulsion primer are used for this.

Counseling! Only gasoline can be used as a mastic solvent dilution agent. Regular auto gasoline is inappropriate in this situation because it releases harmful vapors.

When roofing mastic is being worked on in frigid temperatures, it must be heated. It must be maintained in the room at a minimum temperature of +15 degrees in order to accomplish this.

Step-by-step instruction

1. The working surface is cleaned of dust, dirt, old coating, rust, snow, ice.

It needs to be dry on the surface. It is best to dry it ahead of time; gas burners work well for this. There is a maximum of fifteen percent humidity permitted.

A bitumen primer should be applied to the base if it is porous. Make sure you give it time to fully dry.

To waterproof a roof with bitumen materials, bitumen primer is required. It enables you to improve the base’s adhesion with waterproofing material and prepare it qualitatively. It also increases wettability and strengthens the surface, increasing its durability, both of which have an impact on work speed. This material takes eight to twelve hours to dry. The cost of processing one square meter of surface will rise slightly—by about five to eight rubles per meter—due to the primer’s use.

2. Mastics is applied to the surface using one of the following tools:

• Putty knife;
• Brush;
• Mop;
• Roller;
• Ring.

Pneumatic spraying or the bulk method, which uses rockets (troops) to disperse the material on the surface, are also options.

3. If several layers of waterproofing are created, each layer must dry within 1-5 hours, the time depends on the thickness of the layer.

The surfaces are joined after the material has been spread out in a layer of 0.5–1 mm for glue. It is important to make sure that there are no folds or air bubbles at the same time. The surface is brushed smooth and rolled out with a heavy set roller to stop them from forming. Till the mastic emerges from the seams, press the surface.

Take note! The glued material is not coated with the composition!

Mastic finally dries and takes up to seven days to regain its properties.

Estimated cost

The kind and brand of mastic determines the price. The cost could change based on the location. The following are the primary typical options:

• Bitumen mastic ("Smuffle") – on sale of a bucket of 19.5 kilograms. Price per kilogram on average 55-60 rubles. Used for repair and creation of roll roofs, filling deformed and cracked seams.
• Insulating mastic, bitumen-resin-a bucket of 18.3 kilograms-67-70 rubles per kilogram. The price depends on the brand of mastic. By purchasing a large number – up to 200 kilograms – the price may be lower. Used for the design of roller roofs, for insulating work.
• Bitumen-polymer mastic-a bucket of 18 kilograms-69-70 rubles per kilogram. When purchasing a barrel of 200 liters, the price per kilogram – from 67 rubles.

High-grade waterproofing layers can be reliably and effectively created using cold mastics. It is possible to work with them on any surface, from the roof to the foundation. Compared to working with hot mastic, using cold bitumen mastic is more convenient and requires less time.

Bitumen mastic of cold use: Features of the material and cons and cons of

Bitumen mastic is currently utilized more frequently than other materials to form an isolation layer in construction projects. It can happen both hot and cold, depending on how it is used. Professional builders use hot bitumen mastics, which require special equipment and open flames for heating; cold bitumen mastics are simple to use and only require diluting.

Bitumen serves as the base for the production of mastic. In isolation, bitumen is not a very good insulator; at very low temperatures, it can crack, and at very high temperatures, it melts.

Main characteristics

Note: The product known as bituma is asphalt concrete that is produced during the refining of oil products. Particular polymer additives help to eliminate these drawbacks. They thus obtain a surface that is completely in opposition to variations in temperature and outside influences. Mastic differentiates between durability and dependability.

The thickener, which is made of ground asbestos, peat crumbs, and chalk, is another crucial part of this mixture. These ingredients help lower costs, improve thermal insulation properties, and make mastic even more user-friendly.

Note: Protecting the surface from excessive humidity is the primary objective of using mastic.

As previously stated, there is no need to prepare cold mastic before using it. All you have to do is mix and apply the composition. Use it primarily as a waterproofing layer for roofing. It is applied prior to the installation of roofing material and can also be used for foundation processing and roof repairs. Crucial: mastic that is cold is eaten less hotly. Mastic is resistant to a number of harmful elements and is not susceptible to corrosion processes.

Advantages and disadvantages

As a result of the production process’s use of streamlined technologies, this kind of mastic is growing in popularity with customers. With this bitumen-based cold use mortar, it has become the standard material for the waterproofing apparatus.

Bitumen mastic offers several advantages:

• It dries instantly;
• can be used for spot repairs;
• Easy use, which can not even cope with a professional;
• There is no need to use special equipment for heating, unlike hot appearance, which is greatly simplified by the process;
• She can work on a wooden, metal, concrete or plastic surface;
• has elasticity;
• when applying penetrates the structure of the coating;
• Due to their unique composition, they are resistant to atmospheric phenomena, temperature fluctuations, ultraviolet light;
• An extensive color scheme of mastic is achieved by adding coloring pigments;
• Water mastics are used for internal insulation of the premises.

Along with the benefits, there are some drawbacks as well:

• The material has combustibility;
• Cold mastic of high class can cost more hot.

Depending on the additional impurities, I highlight the following mastic varieties:

• with a polymer base, which includes modifiers that give the material of strength, heat and frost resistance;
• rubber, to which rubber crumb is added;
• latex;
• oil;
• rubber, most often used;
• kukersal, which is also called kukert.

Moreover, the cold use mastic can be:

• Made on the basis of the solvent;
• water based.

With the first, the composition is created in its completed form, so there is no need for preparation. able to be coated to provide waterproofing. Utilizable even in extremely cold temperatures. A monolithic waterproofing layer is created because the mastic contains a solvent and it evaporates instantly.

In roofing, cold mastic is essentially used to create a waterproofing layer. Note: A mastic layer takes 12 to 24 hours to dry, but it takes 7 days for it to take on its characteristics.

The water-based cold mastic is still referred to as the bitumen emulsion. Its production is linked to the application of cutting-edge materials like emulsifier and polymers as well as sophisticated processes. Its application results in a safe and entirely ecologically friendly roof waterproofing. Water starts to evaporate from the emulsion as soon as it is applied to the surface, creating a layer of extremely strong waterproofing.

The bitumen emulsion has the following distinct benefits:

• The most convenient application;
• T.To. There is no solvent here, it is absolutely non -toxic material;
• It can also be used when working inside the dwelling in connection with explosive and fire safety;
• Dry quickly.

The fact that bitumen emulsion cannot be kept or used below plus five degrees Celsius, toto, may be its lone drawback. In a chilly setting, she loses her abilities. This is because the emulsion disintegrates when the fluid turns into a solid state.

There are two possible forms of mastic composition: one- and two-component.The former only fully manifests as a waterproofing coating when the secondary component—such as water—has completely evaporated. When the second element is added in a two-component version, the properties are demonstrated. Essentially, hardener fills this function.

Where it is used

The following are some guidelines for using mastics:

• Mastic with the base of kukersol varnish is the most suitable for the construction of concrete structures;
• Mastics with a rubber base are better than a waterproofing layer, thanks to the composition with rubber, which has good elastic and fluid properties;
• For the installation of roofs, select solutions with polymers and rubber bases;
• Where the spot application is required use the oil composition, t. To. This composition forms the most resistant to changes in the temperature of the coating.

Mastic is employed:

• In roofing work;
• As a protective layer of the roof of the UV rays and the strengthening layer during the installation of tiles;
• In the device of foundations, basements, piles;
• As protection against corrosion of the foundation, as well as when gluing thermal insulation material;
• When applying waterproofing in bathrooms, bathroom, balcony or garage room.

Features of application

The cold mastic’s primary attribute is its total usability.

Methodical implementation:

• The surface for the waterproofing layer is cleaned of contamination;
• Then it is processed by a special primer;

Note: Bitumen primer is frequently used to waterproof concrete, cement screed, and roofing materials.

• Then the mastic is well mixed;
• Application of mastic. This can be done using special devices or with a bulk method. As soon as the mastic is applied, it is well aligned. For greater effectiveness, mastic is better to apply in two layers, each of which is not made more than one and a half millimeters. The subsequent layer is applied only after drying the first;
• Then rolled materials are glued.

Important: It is not advised to use mastic in rooms without a functional ventilation system, per safety regulations. Furthermore, using it in close proximity to an open fire is forbidden.

The nuances of proper operation

The ability of the cold-cured mastic to liquefy is apparent when kneading it. Simply work with this property because of it. It is practically impossible to apply mastic using a mechanical method, and this material is not appropriate for spraying. The mixture has viscosity. As a result, a roller is used here. It is best to use a brush if the mastic composition is liquid.

Important: storing insulating materials properly requires them to be kept tightly sealed off from the elements.

The mixture will solidify and lose its use if it is left in an open container for a day. Mastic is first heated to fifty degrees when working during the winter. Less plus five won’t function at high temperatures or humidity levels, even if the composition is heated. It will be best to postpone all work until ideal circumstances.

In conclusion, mastic bitumen cold application provides a flexible answer for a range of roofing requirements. It is a preferred option for both homeowners and contractors due to its versatility and ease of use in both new construction and repairs. Cold-applied mastic bitumen is safer and easier to handle than traditional hot-applied bitumen because it doesn’t require heating equipment.

Mastic bitumen’s ability to stick well to a range of surfaces, such as metal, concrete, and pre-existing bituminous membranes, is one of its main advantages. Because of its adaptability, it can be utilized for a variety of roofing projects, including sloped and flat roofs. Its adaptability makes it simple to apply around intricate roof details and penetrations, guaranteeing a seamless and waterproof finish.

Furthermore, mastic bitumen is exceptionally resilient to weather, able to withstand a wide range of temperatures and meteorological conditions. Over time, maintenance costs are decreased because of the buildings’ long-lasting protection provided by this durability. Its ability to withstand UV light also contributes to the preservation of its structural integrity and aesthetic over time.

All things considered, mastic bitumen cold application is a cutting-edge, effective, and dependable option for roofing projects. Because of its versatility, user-friendliness, and strong performance, it’s a top choice for guaranteeing the durability and security of commercial, industrial, and residential roofs.
