Bituminous paints are coatings made from bitumen (asphalt) dissolved in organic solvents. They provide waterproofing, corrosion resistance, and protective properties on metal, concrete, and masonry surfaces.
Appearance: Black, viscous liquid
Properties:
Water resistant
Acid and alkali resistant
Good adhesion to substrates
UV-sensitive unless modified
Types of Bituminous Paints:
Type
Description
1. Solvent-based bitumen paint
Bitumen dissolved in solvents like mineral turpentine; quick-drying
2. Water-based bitumen emulsion
Bitumen dispersed in water with emulsifiers; eco-friendly and low VOC
3. Modified bitumen paint
Blended with polymers (e.g., styrene-butadiene) or aluminium for enhanced flexibility or reflectivity
4. Aluminium bituminous paint
Contains aluminium flakes; provides UV protection and aesthetic finish
5. Rubberized bitumen coating
Offers high elasticity, crack-bridging ability; used in waterproofing and roofing
Selection of Type – Based on Application:
Application Area
Recommended Type
Reason
Metal surface (pipes, tanks)
Solvent-based or Aluminium bitumen
Good adhesion and corrosion resistance
Concrete roofs, slabs
Rubberized or Water-based emulsion
Elasticity and non-toxic for buildings
Underground structures
Rubberized bitumen or Polymer-modified
Better crack resistance and longevity
UV-exposed areas
Aluminium bituminous
Reflects sunlight and prevents degradation
Eco-sensitive zones
Water-based bitumen emulsion
Low VOC, safer handling
