What is bitumen, pros and cons of

Bitumen, also known as asphalt matter, is produced by processing oil products, which resemble black resin. On the outside, bitumen mastics resemble pasta-like black resin. Its viscous and plastic qualities set it apart and make it easy to apply to surfaces. Other additives, like polymer, can be added to the product’s composition to enhance its characteristics and make it easier to use. This can result in an invulnerable coating that forms a layer that blocks the passage of liquids.

Additionally, thickeners are added to the material to enhance its qualities; these additions aid in creating a superior insulating layer on the material’s surface. Additionally, substances that create a good degree of adhesion with various bases are used, as well as elements that prevent cracking. Special additives are used in the composition to give it an anti-corrosion characteristic.

Consequently, an even sealed layer is applied to the use of data and other components that may vary slightly based on the kind of product. which the water just cannot pass through to reach the base. The benefits of liquid mastic include the following, which are highlighted:

  • Obtaining a coating without seams, which excludes the leak;
  • Helps to make the surface even and block small flaws of the material;
  • A high level of connection with the base, so that there is no detachment and bloating of the base;
  • The surface of the layer does not crack;
  • It is allowed to apply to rusted areas on the iron, you can use to cover the old roof;
  • Durability, service life reaches 25-30 years;
  • A high-strength indicator on the gap, increased mechanical exposure will not lead to loss of integrity of the product;
  • Ease of use;
  • Does not provide strong loads with its presence on the roof;
  • You can, using the diluent, prepare a means of any consistency.

High-strength indicator on the gap ensures that integrity won’t be compromised by increased mechanical effect.

Numerous benefits do not negate the solution’s existence or drawbacks. You can identify the following drawbacks:

  • For work, it is required to get an even base, otherwise the viscous consistency will lead to the differences in mastic in inclined areas, in order to fix the moment, you can apply the addition of thickeners and cement mixture. If there are significant pits or bugrs, then they are previously recommended to be leveled so that the layer is reliable;
  • Permissible working conditions do not imply rain and negative temperature indicators, so the possibility of application is somewhat limited to weather conditions;
  • It is difficult to regulate the thickness of the distribution of mastic on the surface, which sometimes leads to excessive consumption of the composition.

A mastic agent’s pros and cons dictate its popularity; while there are drawbacks, they are outweighed by the benefits of using the product.

Types of bitumen compositions

Mastic can be categorized into different types on a number of grounds. Understanding the classification will make it easier to select the best course of action, resulting in long-lasting, high-quality protection. Therefore, the following can be distinguished based on the characteristics of technological application:

  • One -component, which are immediately ready for application, it is only necessary to mix them before use;
  • Two -component, two components are sold in one package, the first is the main part of the mastic, the second hardener. Which triggers the process of drying the layer. Their connection together is carried out immediately before covering the material. This type can be stored longer than the first option.

Additionally, there are differences in the constituent parts that make up the composition:

  • Oil types – with additives use cement, chalk, asbest;
  • Rubbering mastic use is associated with the creation of a layer that can withstand enhanced loads, is often selected for roofing, apply follow a spray, the pressure should be strong;
  • Polymer-bitamous, polymers are used to give special properties;
  • Latex, can be used indoors, due to the lack of toxic elements;
  • Rubber, stand out by the ability to stretch more than their original state by 20%, are not amenable to the effects of temperature changes. Can be used to work with the roof, for waterproofing other metal structures.

The product’s application area sets it apart:

  • Roofing-insulating for bulk roofs;
  • Asphalt-hydro-insulating, can be used for the foundation, recreating the road layer;
  • Anti -corrosion, suitable for giving a protective layer to metal structures, including on already affected by corrosion;
  • Glued, serve to glue roofing material.

Additionally, there is a division into hot and cold depending on the application technique.

Types of mastic according to the application method: cold and hot

The emergence of a cold has led to a recent decline in the popularity of hot mastic solutions. There are more challenging working conditions when using hot mastics. The product must first heat to +150 degrees in order to be applied. This is the original kind of waterproofing bitumen mastic. You can adhere rolled materials and sections of the multi-layer roof with their assistance. One can distinguish between the following benefits of funds:

  • Get a high -strength layer;
  • Does not give shrinkage after it has dried;
  • High indicator of the elasticity of the layer.

There are several applications for a cold option in the construction industry. They can be applied to inclined zones without the need for heating, and they don’t require rolling—which is a feature of the hot type—in order to achieve the necessary mass through density. Instead, they can be diluted with solvents. Study their features to determine if they are appropriate for the job:

  • Safety from fires and burns, because they are used in a cold state;
  • It can be applied in low -temperature weather, but then it takes more time to wait for the layer to dry;
  • They are in demand not only as a coating type of waterproofing agent, but also as an adhesive layer for rolled types of materials;
  • Can fill out suture areas, creating excellent protection;
  • Working with them just.

The composition needs to be heated to 30 to 40 degrees in order to carry out waterproofing in cold weather.

It is crucial to add this tool to the dilutors’ composition right away because storing it will prevent the dried solution from retaining its qualities.

The main application in construction

Understanding what a bitumen-based mastic is can aid in comprehending how to use the composition. Utilize a tool for a variety of building tasks. The work on the walls, floors, foundation, and roof is the most well-liked. Below is a description of the application’s specifics.

How to cook Bitumen mastic with your own hands

You can use your hands to prepare a mastic solution. Bitumen, fillers, and plasticizing agent will be needed for this. In terms of ratio, 8.5 kg of the primary component will need 1 kg of filler and 0.5 kg of plasticizing material; this will yield a 10 kg solution. You can use waste oil, asbestos, sawdust, kerosene plasticizer, or mineral wool as filler.

Crushed bitumen must also be used with the filler. It is essential to first heat the bitumen in a thick-walled container while keeping an eye on the solution’s delivery volume. The solution will rise after heating. heated to +190 degrees Celsius, and this indicator needs to stay that way. When the bubbles take on a greenish-yellow hue, clashing starts. The remaining ingredients should then be added gradually while stirring constantly. It’s necessary to remove the foamy portion. Once the foam has settled, plasticizers are added. After thoroughly stirring, turn off the heat.

Consumption and consumption rate

Usage for every 1KV.m. Depending on the kind of mastic that was used, hot views do not cause shrinkage after drying. Indicator average: 2-2.4 kg/sq.m.; layer thickness: 2 mm. Dry residue has a direct impact on consumption; the lower the indicator, which typically ranges from 20 to 70%, the more product is needed.

Bitumen mastic from leading manufacturers

There are several well-known producers of Bituminol mastics that come to mind when discussing tested and superior compounds. The following brands are set apart:
