The consumption of bitumen primer per 1 m2 should be known to you if you intend to use it for waterproofing works.
general description
This composition is a homogeneous black liquid, which is a solution of petroleum bitumen. To soften them, conditions are required, characterized by a temperature of 80 degrees or more, and organic substances act as a solution. The mixture does not contain any foreign matter, and there should also be no heterogeneities. The mixture does not contain toxic solvents like toluene. Roofing and waterproofing work will be facilitated by using a bitumen primer. With it, you can reduce the time of the manipulation, improving the quality of waterproofing.
Varieties of bitumen primer
Consumption of bitumen primer per 1m2 will allow you to understand how much mixture you need to purchase. However, to purchase the composition, it is important to know the varieties of this mixture. Bitumen primers are available for sale in concentrated or ready-to-use form. Before use, the concentrate must be diluted with an organic solvent, namely kerosene, gasoline or white spirit. The ratio should be 1 to 2. The use of concentrate allows you to save space during storage, as well as transportation. If we are talking about a finished primer, then with it you do not need to carry out additional procedures previously, except for mixing. It is ready to use and easy to use.
Application area
If you decide to use the described composition in your work, then you should know the consumption of bitumen primer per 1 m2. To form one layer, it will be necessary to spend from 0.25 to 0.35 kilograms per square meter. The final figure will depend on the roughness and adhesion. Naturally, the smallest amount of materials will be spent on monolithic, durable and smooth surfaces, while whether there are rough, porous and loose substrates, the consumption will be large. If you will know the consumption of bitumen primer per 1 m2, then you can determine how much mixture you need to purchase. To do this, determine the area of the waterproofing surface, and then divide it by the aforementioned flow rate.
Bituminous mixtures are used for priming surfaces according to the type of asbestos cement, concrete, metal, reinforced concrete, wood and porous materials. Among other things, you can use a bitumen primer to carry out work in the field of roofs, as well as for waterproofing, while the mixtures are used as independent waterproofing materials, as well as in combination with other self-adhesive and surfaced materials.
Bitumen primer is used for waterproofing foundations, bridge spans, flat roof bases , underground structures and structures, as well as surfaces of metal pipelines. The product can be used to protect metal surfaces from corrosion.
Norms of use
The bitumen primer consumption rate per 1m2 was mentioned above, but to achieve a positive result, it is important to know the technology of the work. Application of the mixture is carried out on cement-sand, concrete and other rough surfaces. If we are talking about a porous, dusty and uneven surface, then processing must be carried out using a brush or a nylon brush. This application technology provides excellent base impregnation and high adhesion.
Primed surfaces can increase the life of materials. If there is a need to stick rolled materials with a primer, the surface of reinforced concrete and concrete slabs, as well as the seams between the elements, must be primed. Each subsequent layer of web material is glued 4 hours after the installation of the previous one. Roll materials should be overlapped, the width of which is 100 millimeters. In this case, cross-gluing should be excluded. As soon as the canvas is in place, it should be rolled up with a cylindrical roller for special purposes.
Main characteristics
Information about the consumption of bitumen primer per 1 m2 of surface, of course, matters. However, before purchasing this mixture, you should familiarize yourself with the main characteristics, among which: quick drying, waterproofing properties, preventing corrosion processes, the ability to use at low temperatures, a high level of adhesion, resistance to heat, the ability to use for sticking roll materials, as well as the availability water displacing characteristics.
If the average ambient temperature is 20 degrees, then the surface on which the primer was applied will dry out within 12 hours. If necessary, the product can be applied even in the winter, but before that, the base must be cleaned of dirt, foreign elements, snow and ice. Before work, the surface should be dried, warm up the rolled materials in a warm room, where the air temperature is +15 degrees or more. Work should not be started if the ambient temperature drops below -20 degrees.
Application Instructions
When carrying out work using a bitumen primer, intensive ventilation of the room or work in the fresh air should be provided. The material is suitable for work if its temperature has not dropped below +10 degrees. If necessary, the primer or work surface should be heated, however, the temperature of the mixture should not be higher than +40 degrees. As for fire safety standards, it is impossible to carry out work near an open flame.
Bitumen primer consumption rates for different surfaces
Quite often, professional builders and home craftsmen are interested in what is the consumption of a bitumen primer per 1 m2 of concrete surface. This figure can vary from 250 to 450 grams per square meter, as for the slate, as well as the plastered surface. If the application is carried out on steel structures or metal, then the consumption will be 200 grams, on the base of the wood, the consumption is 300-350 grams per square meter, according to the old rolled roofing, the consumption can reach 500 grams per square meter. When repairing roofing with powder coating, consumption increases to 750-900 grams per square meter.
Consumption of bitumen primer "TechnoNIKOL"
The consumption rate of the Technonikol bitumen primer per 1 m2 should be of interest to you if you intend to use this composition for waterproofing work. Approximately 1 liter, which is 0.3-0.35 liters per square meter, will take up 3.3 meters of square surface. Application should be carried out with nylon brushes or brushes in the case of the need to handle hard-to-reach and difficult places, while uniform distribution is made on the surface using a roller. For preliminary cleaning of the surface from contamination and dust, a polypropylene broom should be used. To form a reliable layer, which will be characterized by continuity, the surface must be cleaned of the remnants of the old waterproofing. Primer consumption of bitumen “Technonikol” per 1 m2 may vary depending on the characteristics of the base.
