Description
High-Performance Acid-Resistant Mortar
Potassium Silicate Mortar is a premium acid-resistant and chemical-resistant mortar designed for bedding and jointing acid-resistant bricks and tiles in industrial and chemical applications. It is ideal for tanks, drains, floors, foundations, and chemical processing areas, providing strong adhesion to concrete, ceramic, and metallic surfaces.
This industrial-grade mortar offers excellent resistance to oxidizing and non-oxidizing acids, chlorine gas (except hydrofluoric acid), and salt solutions, making it suitable for harsh chemical environments. With a maximum service temperature of 1000°C, Potassium Silicate Mortar ensures durable performance under high heat and aggressive conditions.

Chemical & Temperature Resistance
- Resistant to oxidizing and non-oxidizing acids and chlorine gas
- Not resistant to hydrofluoric acid (HF)
- Maximum service temperature: 1000°C
Surface Preparation
- Surfaces must be cement-plastered, dry, clean, and free from dust, dirt, grease, or oil.
- Slight roughness is required for optimum adhesion.
- Maintain required slopes, as adjustments cannot be made after mortar application.
Preparation & Mixing
CNSL Resin Mortar is a two-component system consisting of Solution and Powder.
Setting & Curing
- Self-hardening: Chemical reaction occurs upon mixing Powder and Solution.
- Initial setting: 6 – 8 hours at 30°C
- Final setting: 24 – 48 hours at 30°C
- Full curing: 7 days at 30°C
- Ensure no water contact on the lining until fully cured.
Acid Curing
- After the bedding mortar has set, cure the joints with 20–25% HCl solution for at least 72 hours.
- Wash the joints with clean water and allow them to dry completely.
- Apply resin-based mortar into the cured joints.
