In order to prepare the surface of concrete and timber substrates for the application of heat-fused APP and SBS modified bitumen membranes, Bitumen Primer is a bitumen-based primer. This primer is used to condition the surface of the substrate. Bitumen is a mixed substance that is made up of organic liquids that are extremely sticky, viscous, and waterproof. Other names for bitumen include asphalt and coal tar. In the process of laying built-up roofing or membrane waterproofing, bitumen primer is typically utilized for priming concrete and masonry surfaces before the application of the first mopping coat of melted bitumen. This is done in order to facilitate the bonding of the bitumen with the concrete roof deck or stone surface. Primers and black paints made from bitumen that has been oxidized and is mixed with a variety of pure solvents are referred to as bituminous. Bituminous paints come in black and are typically used to coat pipelines, protect concrete and metal buildings, and anchor bituminous membranes. These paints can also be put on wet surfaces. Appropriate for use in securing bituminous coatings that have been hot applied to metal surfaces. They are also appropriate for closing the porosity of concrete substrates and for preparing a proper binding primer for numerous layers of bituminous waterproofing and bituminous membranes. Other applications for which they are well suited include the following: The product has a short curing period, excellent substrate penetration and adhesion, and no tackiness on the surface after it has cured. Primers made of bitumen can be divided into two distinct groups: those made with a solvent and those made with water. 
Solvent-based primer
The solvent-based primer is of the highest quality and dries very quickly. It is a bituminous primer that is solvent-based. In order to increase the bonding of bituminous materials, it performs the functions of both a primer and a sealing coat for masonry and concrete. When it dries, the product creates an odorless and seamless free bitumen film that is ideal for the protection against water damage of metals, concrete roof felt, fiber cement, corrugated metal, asphalt, and wood. Additionally, the film is free of bitumen. It is designed to be used as a prime coating, which involves the initial stage of surface preparation prior to the application of torch-on or self-adhesive waterproofing material. The prime coating is essential for ensuring the strong adhesion of bitumen-based waterproofing solutions to porous, rough, and dusty surfaces. This can only be accomplished with the application of the coating. The primer is a mixture that consists of high-quality bitumen and organic solvents that have been carefully chosen. It offers improved penetrability, a quicker drying time, and a greater capacity for covering the ground. This primer can be applied to a surface with either a large or tiny brush, depending on your preference. It is applied all at once to the base, which results in an increased amount of convenience and an improved level of performance. The primer is a mixture that consists of high-quality bitumen and organic solvents that have been carefully chosen. It is suitable for applying to a wide range of materials including iron and steel, lead, zinc aluminum, cement, concrete, stone, wood, felt, and brick, and is primarily used for metal preservation, protecting drinking water tanks as a protective coating for concrete structures, stone, bricks, concrete screeds, and sand or cement surfaces over coating felt or woo. It is resistant to low concentrations of alkalis and acids and can withstand prolonged oxidation. This primer is not supposed to be diluted in any way before being used. Use a brush or a spray to apply, A minimum of two coats of bitumen paint should be applied. The first coat should be allowed to dry (normally two to four hours depending on the weather condition) before the second coat is applied. The application rate should be between 4-6 m2 per liter, but the coverage will vary depending on the porosity of the substrate. In conditions of normal ambient temperature, the drying process takes three to four hours. Keep a safe distance from any ignition sources. It is possible to preserve it at an ambient temperature. 
Water-based primer
An emulsified bitumen-based primer or a water-based primer is designed for use as both a priming and a sealing layer in a variety of applications. Primer is used to help block dust and minimize the porosity of concrete. Because the product has water in its formulation, it does not support good adhesion and does not penetrate the substrate. Because of this, the product is not flammable and does not present any risks when it is used. The item has no discernible smell. It is an emulsion made entirely of bitumen that is distributed in the form of a thick liquid for the purpose of providing water resistance to substructure and superstructure areas in buildings and civil engineering projects. The coating has a color similar to dark brown coffee and dries into a protective layer that is black and flexible. The primer is manufactured using a bitumen dispersion in water as its foundation; it does not include any solvents in its composition. Because the primer has no discernible odor, it is an excellent choice for use in enclosed spaces. This water-based primer offers a variety of waterproofing and damps proofing benefits, including general protection against water and dampness in concrete, brick walls and foundations, asbestos cement sheets, roofing felts, and woods, among other materials. Steelwork, pipelines, and metal are all shielded from harm here. Before using the drum, you are required to shake it up. Before emptying the drum's contents into the container, you need to roll it back and forth on the ground. Additionally, it must be applied with a roller or a brush. To obtain a finish that is long-lasting, you need to apply at least two coats. 
Once the previous coat has completely cured, the second coat and any following coatings should be applied perpendicular to the first coat, and at least 24 hours should pass between the application of the first and second coats for optimal curing. Applying this primer to moist but not water-logged surfaces is possible; for a smoother application, dampen the brush before use and continue to dampen it intermittently while applying the primer. Prior to producing any bitumen primer, it is important to pay attention to the quality of the raw materials.
