Application steps

SUBSTRATE PREPARATION

Surfaces of cracks, joints and voids need to be clean, free of loose particles, dust, oil and any other bond-breaking substances. Any dirt must be blown out with compressed air.

MIXING

All parts are provided in pre-assembled container sizes to the correct mixing ratio.

  

1. Component A

Empty the contents of the small container (Part. A2) completely into the container of Part A1. Mix the parts thoroughly with a suitable stirrer/mixing paddle for three (3) minutes.

   

2. Component B

Part B is a powder and must be dissolved in 17 L of clean water. Mix three (3) minutes.

  

The activated components A & B are stable during 4 h and are applied by a 2-c pump at the ratio of 1:1 parts by volume.

CLEAN UP

Pump cleaning from liquid material with water only. Cured material can only be removed mechanically.
