Description
Durable Acid & Chemical-Resistant Mortar
Sodium Silicate Mortar is a high-performance acid-resistant and chemical-resistant mortar specially designed for bedding and jointing acid-resistant bricks and tiles in industrial applications. It is ideal for tanks, drains, floors, foundations, and chemical processing areas, providing excellent adhesion to concrete, ceramic, and metal surfacesfor long-lasting durability.
This industrial-grade mortar is resistant to oxidizing and non-oxidizing acids, alkalies, and chemical solutions, except hydrofluoric acid and concentrated sulfuric acid in vapor phase. With a maximum service temperature of 1000°C, Sodium Silicate Mortar ensures reliable performance under high heat and harsh chemical exposure. Its self-hardening and trowelable formulation allows easy application, uniform bonding, and strong mechanical properties.
Key Features

acid-resistant lining projects
Chemical & Temperature Resistance
- Resistant to oxidizing and non-oxidizing acids (pH range 0–6), except where sulphuric acid is present in vapor-phase wet-dry conditions or in concentrations above 93%.
- Not resistant to hydrofluoric acid (HF) or water immersion.
- Maximum service temperature: 1000°C
Surface Preparation
- Surfaces must be cement-plastered, dry, clean, and free from dust, dirt, grease, and oil.
- Slight roughness is required for optimal bonding.
- Maintain required slopes; slopes cannot be corrected after mortar application.
Preparation & Mixing
Sodium Silicate Mortar is supplied as a two-component system: Solution and Powder.
Setting & Curing
- Self-hardening occurs due to the chemical reaction between Powder and Solution.
- Initial setting: 5 – 7 hours at 30°C
- Final setting: 24 – 48 hours at 30°C
- Full curing: 7 days at 30°C
- Ensure no water contacts the lining until fully cured.
Setting & Curing
- Once bedding mortar is set, cure the joints for 72 hours with 20–25% HCl.
- Wash joints with clean water and allow thorough drying.
- Fill joints with resin-based mortar after drying.
