Here is the factors affect the coverage area of bitumen paint:
The coverage of bitumen paint depends mainly on the type and porosity of the surface. It covers 4 to 6 m² per litre on porous surfaces and up to 11 m² per litre on smooth, non-porous surfaces.
Different materials, such as brick, wood, concrete, metal, asbestos-cement, and stone, also affect the amount of paint needed. The method of application, brush or airless spray, can also affect coverage.
Additionally, the thickness of each coat and the drying process can influence the total area covered. Choosing the right surface preparation ensures better coverage and long-lasting protection.
Hope this helps you understand the coverage area of bitumen paint.

The Bituminous paint coverage area depends on the surface type and its porosity. Smooth and non-porous surfaces give better coverage, while rough or porous surfaces absorb more paint. Here are the average area which this paint covers:
On metal and smooth surfaces, bituminous paint covers about 10 square metres per litre per coat. These surfaces do not absorb much paint, so one litre spreads easily and evenly.
On porous surfaces like concrete, masonry, or rough plaster, the coverage is lower. In such cases, bituminous paint covers around 8 square metres per litre when used as both paint and primer.
When workers use bituminous paint as an adhesive for malthoid sheets, the coverage reduces further. In this application, one litre covers approximately 5 square metres because the paint layer is thicker.
