DIRECTIONS FOR USE

1

PREPARE

Ensure the gaps and brick surfaces are clean, sound, and free of dust, dirt, or loose particles. Lightly dampen the surface with water before application.

2

MIX

Gradually add the powder to clean water. Mix manually or with a slow-speed stirrer to achieve a smooth, lump-free consistency. Let the mixture rest for 5-10 minutes, then remix before use.

3
Trowel

APPLY

Fill the gaps in the brickwork (between 10 mm to 25 mm thickness) uniformly using a pointing trowel or suitable application tool. Ensure the gaps are completely filled without voids.

4

FINISH & CURE

Clean any excess material from the brick face immediately with a damp cloth or sponge before it sets. Allow it to cure undisturbed (Initial setting time is approx. 1 Hour).
