Bituminous paint, also known as natural bitumen paint, is a specialized kind of paint that is frequently utilized in the building industry for the purposes of waterproofing, corrosion resistance, and damp proofing various structural parts. Bitumen or coal tar is dissolved in mineral spirit or naphtha to make it, and then it is applied to the surface of the structure either in a liquid or semi-liquid state. Bitumen paints have important properties such as:
- The durability and adaptability of bituminous paints can be improved with the addition of polyurethane or acrylic polymer ingredients during the manufacturing process.
- Bituminous paints are alkaline-resistant.
- Since bituminous paints have strong adhesive characteristics, they are ideally suited to fulfill the role of an effective barrier against the passage of air and moisture.
- The bituminous paint is hard, waterproof, and long-lasting, and it is resistant to the harsh chemicals used in production as well as ultraviolet light.
- Rust can be prevented on surfaces by using bituminous paint.
- The amount of coverage that may be expected from one liter of bituminous paint is directly proportional to the porosity of the surface it will be applied.
- On metal and flat surfaces, you can expect to get 10 square meters of coverage from one liter of bituminous paint.
The application of bituminous paint can be done with either a brush or a spray gun, as it is a ready-to-use product that does not need to be thinned.
- They have a low cost, a quick drying time, and are simple to work with.
- The construction sector makes primary use of bituminous paint for the following applications:
- On foundations, iron, steel, metal projects, castings, asbestos cement sheeting, and structural concrete surfaces, bituminous paint is applied. Also suitable for use on metal structures.
- It is possible to coat ferrous metals, non-ferrous metals, and other building materials with bituminous paint in order to protect them against the effects of exposure to maritime conditions.
- It is a coating solution that is flexible, and it may be applied both above and below the ground.
Also, the degree of surface preparation has a crucial role in determining the performance of bituminous paint. Pay attention to the following tips to achieve the best results.
- Before beginning the painting process, it is essential to ensure that the surface to be painted with bituminous paint is clean and dry. It cannot contain any evidence of filth, rust, grease, or any other contaminant. Additionally, it is necessary to remove any loose or old paint from the surface.
- Before applying paint to metal surfaces, they must be cleaned thoroughly with a wire brush or sandpaper. To clean large metal surfaces, either shot blasting or sanding equipment can be used.
- When applying bituminous paint, parts of the surface that will be exposed to harsh marine environments must be primed with an anticorrosive primer.
- It is vital that the paint is applied evenly and in the required number of coats to the entire surface.
- Please allow a minimum of thirty minutes for each coat to dry between applications. Before backfilling, wait seven days to check that the treatment has taken effect.
natural bitumen paint
Paints are typically found in a liquid condition and are composed of a blend of pigments and binders. Natural bitumen paint, for instance, is an architectural composition that is made of bitumen and is typically diluted with natural solvents. On concrete, asphalt, metal, wood, and pipe surfaces, bituminous paint is applied as an exterior coating, which also serves as a sealer and a waterproofing agent. It has a greater resistance to the elements. When painted onto a surface, a paint coat dries as a solid film. This film shields the surface from a variety of threats, including corrosion, the effects of weathering, chemical assaults, and others. Paints can enhance the life of structures made of timber or metal by providing a protective layer. Paints offer not just protection but also an aesthetic appeal to the surfaces they are applied on. Therefore, paints play a significant part in the operations and projects related to construction. All paints are not suitable for all circumstances. It is possible that different kinds of paint will be necessary for the various environments. You can make bituminous paint by dissolving tar or asphalt in petroleum or white spirit. This creates the paint. They give the surface a dark look caused by their presence. Paints made of bitumen are typically utilized for metal structures that are submerged in water, such as iron pipes that transport water. The resistance of bituminous paints to alkaline conditions is quite high. Bitumen Paint is a synthetic rubber copolymer modified waterproofing coating that was designed for use in applications below ground that are not important. Even in the most difficult waterproofing conditions, paint made with water-based bitumen is incredibly durable while retaining a high degree of its original flexibility. Primers and paints made with bitumen have been used for damp proofing for many years and will continue to be used for many more years in the future. It is of the utmost importance to have a solid understanding of the nature of the damp problem, its origins, and the most effective means of resolving it. If a wall is damp because of a leaking radiator pipe, there is no need to add bitumen paint to the wall because it will not adhere properly. In other words, identify the issue and work to resolve it. The only use that bitumen paints serve is as barriers. It does not indicate that the damp disappears, and if the problem is not fixed, the bitumen will simply de-bond as illustrated in this image. Because this wall does not have a damp-resistant course, there is always the possibility that there will be an issue with moisture rising from the ground. The bitumen paint simply deteriorated over time, which allowed moisture to penetrate the surface and led to the rotting of the stringer supporting the staircase.
