Bitumen primer consumption per 1m2: characteristics, norms, instructions

The consumption of a bituminous 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 liquid of black color, which is a solution of petroleum bitumen. To soften them, conditions that are characterized by a temperature of 80 degrees or more are necessary, and organic substances act as a solution. In the composition of the mixture there are no foreign inclusions, and there should be no inhomogeneities. The mixture does not contain toxic solvents of the type of toluene. Roofing and waterproofing work will be facilitated if using a bitumen primer. With it, you can shorten the time of manipulation, improving the quality of waterproofing.

Varieties of bitumen primer

The bitumen primer consumption per 1m2 will allow you to understand how much of the mixture needs to be purchased. However, for the purchase of the composition it is important to know also the varieties of this mixture. For sale, bitumen primers are presented in concentrated or ready to use form. Before use concentrate should be diluted with organic solvent, namely: kerosene, gasoline or white spirit. In this case, the ratio should be 1 to 2. The use of concentrate allows to save space during storage, as well as transportation. If it is a ready-made primer, then it is not necessary to perform additional procedures with it, except for mixing. It is ready to use and easy to use.

Application area

If you decide to use the described composition in the work, then you should know the consumption of bitumen primer per 1m2. 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 the ability to bond. Naturally, the least amount of materials will be spent on monolithic, durable and smooth surfaces, whereas whether it is a question of rough, porous and loose bases, the expense will be great. If you know the consumption of bitumen primer for 1m2, you can determine how much of the mixture must be purchased. To do this, you need to determine the area of the waterproofing surface, and then divide it into the indicated flow.

Bituminous mixtures are used for priming surfaces like asbestos cement, concrete, metal, reinforced concrete, wood and porous materials. Among other things, you can use a bitumen primer for work in the field of roofing, as well as for waterproofing, while the mixtures are used as independent waterproofing materials, as well as in combination with other self-adhesive and welded materials.

Bitumen primer is used for waterproofing foundations, bridge spans, bases of flat roofs, underground structures and structures, as well as surfaces of metal pipelines. The product can be used to protect metal surfaces from corrosion.

Usage rates

The rate of bitumen primer consumption per 1m2 was mentioned above, but to achieve a positive result it is important to know also the technology of the work. The mixture is applied to cement-sand, concrete and other rough surfaces. If it is a porous, dusty and uneven surface, then the treatment must be done with a brush or a kapron brush. This application technology provides excellent impregnation of the substrate and high adhesion.

Priming the surface allows you to extend the life of materials. If there is a need to paste roll materials with a primer, the surface of reinforced concrete and concrete slabs, as well as the seams between the elements, must be primed. Each next layer of roll 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 avoided. Once the canvas is in place, it should be rolled with a special-purpose roller.

Main characteristics

Information on what the consumption of bitumen primer per 1 m2 of surface, of course, matters. However, before acquiring this mixture, you should familiarize yourself with the main characteristics, including: quick drying, waterproofing qualities, an obstacle to corrosion processes, the possibility of using at low temperatures, high adhesion, resistance to heat, the possibility of using for gluing roll materials, Water-displacing characteristics.

If the average temperature of the external environment is 20 degrees, then the surface on which the primer was applied will dry for 12 hours. If necessary, the product can be applied even in winter, but the base before it must be cleaned of contaminants, foreign elements, snow and ice. Before work, the surface should be dried, roll materials heated in a warm room, where the air temperature is +15 degrees or more. Work should not be started if the temperature of the external environment has dropped below -20 degrees.

Application Instructions

When carrying out work using a bitumen primer, intensive ventilation of the room or work in the open air should be provided. The material is suitable for work if its temperature does not drop below +10 degrees. If necessary, the primer or work surface should be heated, but the temperature of the mixture should not be above +40 degrees. As for the norms of fire safety, it is impossible to carry out work near an open fire.

The rates of bitumen primer consumption for different surfaces

Quite often, professional builders and home masters are interested in what is the consumption of bituminous primer on 1m2 of concrete surface. This figure can vary from 250 to 450 grams per square meter, as for the slate, as well as plastered surfaces. If the application is carried out on steel structures or metal, the consumption will be 200 grams, the basis for wood consumption is 300-350 grams per square meter, the old roll roofing consumption can reach 500 grams per square meter. When repairing the roof over the coating with powder, the consumption is increased to 750-900 grams per square meter.

Consumption of bitumen primer "Technonikol"

The rate of consumption of the primer bituminous "Technonikol" at 1m2 should interest you if you are going to use this compound for waterproofing works. At 3.3 meters square surface will take about 1 liter, which is 0.3-0.35 liters per square meter. The application should be done with nylon brushes or brushes in the case of the need to process difficult and difficult places, while the uniform distribution is done over the surface with a roller. To pre-clean the surface of dirt and dust, a polypropylene broom should be used. To form a reliable layer that will be characterized by continuity, the surface must necessarily be cleaned of the remnants of the old waterproofing. The consumption of the primer bituminous "Technonikol" per 1 m2 may differ depending on the characteristics of the substrate.
