Acid Proof Bitumor Mastic
Acid Proof Bitumen Mastic is a heavy-bodied, trowel-applied membrane compound formulated to serve as the critical secondary containment layer beneath acid-proof brick and tile linings. Applied directly over prepared concrete or steel substrates, it fills surface irregularities and creates an impermeable, chemically resistant barrier that prevents corrosive media from reaching the structural substrate — even if the primary brick lining develops microscopic cracks over time. Imperial World Trade supplies bitumen mastic as part of its complete Triple-Shield lining system, ensuring no weak link exists between your brick lining and the structure it protects.
- Impermeable Barrier: Dense, void-free application eliminates pathways for acid migration to the concrete or steel substrate beneath.
- Chemical Resistance: Effective against dilute to moderate concentrations of sulfuric, hydrochloric, and nitric acids.
- Excellent Adhesion: Bonds strongly to sandblasted concrete, steel, and FRP surfaces without primer in most applications.
- Flexibility: Accommodates minor structural movement and thermal expansion without cracking or debonding from the substrate.
- Trowel & Spray Application: Supplied in a consistency suitable for both hand troweling and mechanical spray application on large surfaces.
- Compatible Overlay: Chemically and mechanically compatible with all resin-based and silicate jointing mortars used in the overlying brick lining.
Acid Proof Bitumen Mastic is not an optional accessory — it is the foundation of a reliable lining system. Imperial World Trade ensures every mastic supply is matched to the specific chemical environment and brick lining system specified for your project.
