Water-based bituminous mastic is a type of single-component sealant materials and products that convert into a flexible solid with excellent adhesion to the surface after the solvent used evaporates.
Benefits
- Suitable flexibility
- Excellent adhesion to various surfaces, including concrete, brick, asphalt, metal, wood, etc.
- Being cheap and economically
- Ease of application and no heat required
- High resistance against different types of chemical compounds and environmental conditions
- Environmentally friendly
- Can be diluted with water
- Can be applied with a brush, spatula and spray
Applications
– Waterproof layer on concrete and brick in water storage tanks and structures
– Sealing layer in buildings and roofs
– The sealing layer of all types of water supply channels, pipes and concrete water tanks
