How to

Step by Step Guide

1. Preparation - Cleaning

2. Preparation of Cartridge

Place cartridge in dispense gun. Remove cap from cartridge. Dispense a small amount so that material is coming out of both sides of cartridge. Attach mix nozzle and dispense a bead at least half of the length of the nozzle. The material is ready to use.
