Sodium vs Potassium Silicate Mortar for Acid-Resistant Brickwork
Compare the binder system, working time, and project chemical exposure before choosing an acid-proof mortar.
Sodium and potassium silicate mortars are both used for acid-resistant brick and tile work, but they are separate formulations. Their working times and published strength values can differ. A selection should begin with the process liquid, concentration, temperature, cleaning practice, and the brick or tile to be laid.
Compare the complete system
The mortar joint is one part of the lining. Check compatibility with the acid-resistant brick, the substrate, and any membrane or backup layer. Review the grade's chemical-resistance guidance and installation instructions. A higher compressive-strength figure does not automatically make one mortar suitable for every chemical exposure.
Plan mixing and laying
Confirm supplied components, mixing proportions, pot life, joint thickness, and cure before service. Prepare only the quantity the crew can place within the working time. Protect new work from conditions that would disturb setting or contaminate the joints.
