Anleitung Step 1 No electricity? No mixer? No problem! Just bring the mixing bag and you’re ready to go. Step 2 Put the substance to mix into the mixing bag. Tip: Put the mixing bag over the material bag and only then tilt to minimize dust. Step 3 Add the correct amount of water directly into the mixing bag. Step 4 Close the mixing bag and then rotate it several times around its axis. A good mixing can be achieved after only 30 seconds. Step 5 Tilt the bag at the desired position, repeat all the steps and when finished simply wash the bag with water.
