Mortar Mix S

Use Mortar Mix S to lay block and brick BELOW and/or ABOVE grade. This product has excellent board life and workability. Perfect for exterior use.


One 30kg (66lb) bag of Mortar Mix S lays 14 standard block or 31 Max Brick with a 1cm (3/8”) joint.


A 30kg bag will use approximately 4 litres of potable water.
  1. Empty the required amount of material into a mortar box, wheelbarrow or onto a smooth working surface.
  2. Form a crater and add potable water, a little at a time, and mix thoroughly.

Note: If the mixture is thick, then add more water, but avoid a runny mixture.
Remixing reduces performance. Mortar should have full coverage on all surfaces for long lasting results. 

For best results:
  • Always use clean equipment, tools and potable water.
  • All surfaces should be clean and free of oil, gas, paint, grease, etc. before applying Mortar Mix.
  • A mechanical paddle-type mixer is recommended.
  • Use a measurable container so the exact amounts are used for each batch.
  • Mix for 6 to 8 minutes. Thoroughly dampen the brick, block or repair area before applying the new Mortar to prevent premature drying of the new material.
  • Keep the new Mortar damp for at lease 3 days by occasional fine spraying of water.
  • Exceeds ASTM C-270 for Type “S” Mortar when mixed and installed as directed.
  • Avoid working in extreme heat.
  • Use only when the temperature is 5°C (41°F) and rising. In cooler weather, use warm (not hot) water.
